Needs to be mentioned that when using this memory saver and you unhook the + and - from the cars battery you still have to be careful as the + connector is still live and would shorten up when getting in contact with any grounded metal.
and presumably if you touch the terminals together on the crocodile clips on the memory saver, it's also still live so could blow a fuse on the OBD connector
Years ago i worked in a motor factor and we used to connect a small motorcycle battery to the leads while disconnecting the main battery so the radio, alarm and any other electronic devices never lost power. Simple solution!
I recently also purchased a Bosch battery from Tayna Batteries. I was very impressed with speed of delivery, price, packing, and the battery itself. I will certainly use them in future. Interesting video, thanks.😀🇬🇧
Same here. As soon as he started fitting it I thought hang on, wheres the battery insulation cover?? My Astra has a battery cover. Useful in cold weather. Helps the battery to hold charge.
It's a sleeve to keep heat in the battery and a ok bit of kit but just leave the car running when you change the battery and the radio codes will stay in and all the stations will be saved as well just rap a rag around the terminals so they dont touch
As his is power the car from another battery I think it won’t make a lot of difference which terminal you removed because if he was to short the positive to the chassis he will blow his ECU up from the other battery current so it’s a very scary procedure having the car electric systems powered in that way I think I’d rather find the radio code out and have it all shut down properly and safely myself
@@neilmurphy845 well my VW caddy which essentially had the same radio didn’t require a code it was only the days of the fords and the Vauxhalls had radio codes now the radios are built-in to the dash they don’t think they bother with security codes anymore?
@@PaulsRoadshow don’t think these have codes no... well technically they do but only needed if units are swapped from one car to another... still a good video and a good thing to have...stops them moaning about losing the clock time, stored radio stations etc...
these radio don't have radio code most car don't these day they get program with the car vin number and the radio request the vin from the body computer to make sure the vin matches if the vin matches then the radio will work if you took the radio out from that car and put it in a different car it will lock out or beep and it would need programing to the new car
Good to know, but I would say that RAC changed battery on daughter's Focus, (2002!), and she had to find the radio code. It was original radio - but older car, of course.
What we do in work about the radio codes is to remove the battery while car is running and put the new one in keeps the radio codes and don’t worry car will not die for a good while
23 years of working in the Motor Trade I never needed a code saver for a Skoda? I have bought 2nd hand original skoda head units to replace aftermarket ones and still never needed a code. I know that some cars do need a saver plugged in before anyone says it including some other old VAG cars but never a Skoda. Good video all the same to make people aware and no harm using a saver anyway.
Got to repeat what a number of other people have said. Disconnect the battery - Negative first, then the positive. Installing - Positive first, then the negative (negative earth vehicles). Again as others have stated, with the OBD code saver connected, the positive battery clamp will be 'live', so will need to be isolated from any contact with the body or engine.
Newer radios are tied to the vin of the car, it will ask for a code until you turn on the ignition for the first time after changing battery. Once immobilizer is disabled, the radio will unlock.
Modern car radios only need the code to start ups after a battery change or full loss of power, they very rarely lose the stored settings/radio stations either, unless left without power for 24/48 hrs, they have capacitors to store the minute power needed to keep the settings etc.
I have used this method for years. In my case, I have bought a tiny 12 V, 9Ah AGM battery for about $20, the one that you would use in an UPS and toghether with the OBD tool, I store them in a small toolbox that I can take with me wherever I like, it's so portable. I recharge that small battery every couple of months. It's powerfull enough to power the car for days. It is true that I haven't thought of this method all by myself, I saw it being used at a local battery change shop and it stuck with me until I made one for myself. I order that OBD tool from Ebay for another $20 or so.
shows that its working. if every car made today got rid of it, people would nab these modern complicated head units and sell em for £500 a pop. look at the current cat converter thefts. did not think of tha did ya

Thank you James. I’d have to say I wish for more informative videos on the mk2 Fabia (HB - TSI) but appreciate this isn’t a tailored channel. You’ve taught me so much so thank you.
Simple solution connect a booster pack to the battery terminals before you fully remove them from the dead battery and then fit replacement battery in place. ..job done.
Hang-on. maybe I'm being a bit harsh on VAG. I think I can see one design improvement that VAG appear to have made to the bonnet scuttle area ( Immediately, underneath the wipers/windscreen). They've extended the width of the plastic gutter to cover what, on my model are the drain holes into the engine compartment. The design of the scuttle and drain holes on my 2003 model are open to the elements and collect all msnner of leaves and crud, which, if not cleared in a timely way, form a lovely agricultural tilth in the oainted scuttle bottom. A right breeding ground for corrosion.
When I changed my battery on my Passat the code was missing on my book too, all you need is the serial number from the radio, the vin number and a V5 and Skoda will give you the code. That’s what I was led to believe anyway. On that note, that OBD saver is an amazing tool!
original radio/navi is paired with car. so if you have disconnected battery, the first thing after reconnect ist to turn the key. then the radio will scan if it is still in the original car and decodes itself.
Well Done and as you did, always its the negative is the first lead to take off and the last one you connect, the amount of people who don't know that (unless very unlikely its a positive earth car a persons working on (pre 1962))

I have a 2013 Fabia and never had a jacket from new. Also my battery has died and been changed but never had to do this luckily enough hence why I'm watching this as I'm curious about it.
You didn't mention that usually sealed batteries have a vent hole which is normally blanked for transportation and therefore should be removed prior to fitting. Seems a good piece of kit though and saves messing around with jump leads etc.
I see the Value Analysis boys at VAG production design have been busy with the battery compartment - no hinged battery cover on the battery on the 2012 model - not much protection for the heavy duty link fuses. My 2003 saloon has a lovely cover with the link fuses integral, to keep it nice and warm in winter and to protect the link fuses from "Freeze-thaw" effect. So, lots of lovely "early onset" failure jobs created for the recovery and breakdown boys when the link on the starter motor breaks (Usually the first to go). Amazing how manufacturers, as they go futher into each models production run find new ways of economising on the design and saving even more oennies to contribute to VAGs bulging coffers. Would the other alternative to buying the £20 OBD device to record the radio code, be to borrow a VCDS cable and a laptop or tablet set-up with VCDS software. Try the Briskoda website. Its also useful to have a VCDS or OBD computer interface available, as you can then cancel any error codes that pop-up in the EMU/ECU as a result of either the battery depleting and outputing low voltage or/and the actual act of removing and replacing the battery. Be assured these error codes do arise and they will, if left unaddressed effect some aspect of the cars operation. As a result of 2 months lack of use due to lockdown, my Fabia's battery went flat. VCDS scan prior to battery removal, showed no error codes other than one oermanent one for the aircon which has been out of use for a long time. On re-installing the battery after a re-charge, the car was taken for a run and found to be over-fuelling at high revs (Accelerating uphill, foot-off) When subsequently scanned on VCDS, an "Excess Flow" fault was reported in the EGR and additionally in both door control modules. These fault codes were subsequently cancelled using VCDS - its worth noting that both of these faullts hadn't been reported before this series of events. After another run, a subsequent VCDS scan showed the error codes didn't reoccur. It is to be oresumed that just the low to non-existent voltage of a discharged battery or/and the electrical effects caused by its removal and replacement by a fully charged item were sufficient to corrupt the "Variables" section of the EMU memory. That said, the door card modules (Which hold the ekectronic control gear for the electric windows and central locking outposts)and EGR, which both include switch connections always get a bit sticky after a period of disuse, or in the case if the electric window switches, this can iccur if moisture seeps in.
That is handy. seen that in motor factors and didn't know what it was for but that's is handy ill get one and its there if I ever need to disconnect battery off some other car with no radio code.
Only think you forgot to mention is that the car live battery terminal remains live when the obd2 memory saver is connected and you have to ensure that the terminal does not touch any metal part of the car chassis
Bought a fabia 1.4tdi in December last year and found all your gearbox vids very interesting and now coming through with the goods again saving me a world of pain as I need to change the battery 😂
No need to buy a special tool to plug into OBD port. Just connect any 12v supply to the car at any convenient spot - many cars have posts for this. And put the battery sleeve back on. And code the battery to the ECU if required (probably not on this vehicle but the OEM battery did have the code on it so maybe it is necessary) If a new battery is not coded to the ECU it will die very very quickly.
Useful tool but I normally just hook some jump leads up to another car if I need to. I was under the impression that most cars are coded to the body computer so issues like this arise if you swap the radio to another car. I could be wrong, it has been known 😄 Also, when a car has a decent battery box, I put the receipt in a large self seal bag and keep it underneath the battery, not lost one yet but the battery always dies after the guarantee.
Hi I have only recently discovered your channel,Great Stuff man!! Just a word about Tayna batteries they come in at a good price. The issue is if you have a problem they wont replace it. I bought one with a five year guarantee it failed after nine months I sent photos, e mails, videos nothing worked. They want you to send it back so that they can test it and come up with a excuse not to replace it. It defeats the object I now buy locally if it fails just take it back. Hope your ok you've not posted for a while. Thanks Mike
these are a good little tool, I bought one recently [ebay, think it was a fiver] to change the battery on our Pug308, I recently had to change battery on my Grande Punto as well and I lost all the menu settings, was a right faff to set it all back up, didnt need a radio code though and strangely on that it kept it stations in memory. I seem to have a box full of various OBD2 things.
Over thinking it tbh ... just keep a set of jump leads attached and connected to a spare battery whilst removing from the battery terminals. Works the same and no need to faff checking you have a fully charged battery👍 P.S. think it’s been mentioned, but you forgot to put the Battery sleeve back on🥴
Changed my kangoo maxi battery in November it was locked out thankfully code was in hand book putting in said code that was a different matter good channel for tips and advice 👍
You could buy a smart charger for car battery, almost same price and it has built in option for supporting all vehicle electronics when changing battery. Anyway, another interesting video..
My E70 X5 battery failed, it had been replaced by the previous owner at a well known high-street garage ahem... "SwiftFit" and they didn't code it to the car which eventually killed it. I found out that new batteries need to be coded to the car which was news to me. I miss the good old days of a 5 minute battery swap.
all vag and skoda have the radio code built in for that car dont matter if you disconnect the batter 12 times day that radio will not looz its code on the other hand if you take the radio out of that car and put it in another skoda then you will need you code its like peugeot and citroen have the same kinda setup you have to program it into the ecu
When I changed the battery in my Audi A4 I had to go into the ECU BCM and change the battery’s stored serial number in the coding using a scan tool I think it’s to tell the cars ECU that you’ve changed the battery for a new one so the charging rate is reset I don’t know whether this is true it’s Skoda cars I thought you have a scan tool have a look and see if your has a battery update procedure ? As my VAC101 has a special option for doing this it’s called coding the battery
VAG batteries do tend to be pretty good from factory. My Golf's original battery lasted for 11 years. And yes that does look like an original battery to me. Both my golf and my dad's audi had the same type of battery from the factory.
Useful video but on a VAG car, the canbus radio knows its in the right car and will not need a code even if you physically take the radio out and put it back in again. It will however need a code if it goes into a different car
If it's factory stereo, yes it's a good idea to have the code BUT when i had my polo, if you disconnect the battery and reconnect, it will ask for the code but you can just turn igntion on and shut and open the drivers door and it will start working again
Save your money. Connect a spare battery to your starter motor live and to a good ground, check the continuity with a multi meter, then change your battery.
That's a great a tool but is much easier just to get a set of jump start cables hook them up to the battery terminals before taking them off and then hook the other end to a second battery or my case the run round then it's all good has to be done with Mercedes and any high end vehicles great tool though
If it's all factory. The radio should keep the code stored in it's memory so when it's switched back on, everything should talk to each other and switch on. Mind you, I'm sure it doesn't always work, but I've never had an issue.
Did you do the ecu battery adaptation using your scan tool afterwards? Another great video, keep them coming. I enjoyed watching your toolbox tour ones again while you tube sesrching

The stereo code is stored on the ecu on most modern cars , if its the genuine stereo that came with the car
Correct. My 2008 Fabia did not need any re-coding, everything was remembered

It is to be oresumed that just the low to non-existent voltage of a discharged battery or/and the electrical effects caused by its removal and replacement by a fully charged item were sufficient to corrupt the "Variables" section of the EMU memory.
That said, the door card modules (Which hold the ekectronic control gear for the electric windows and central locking outposts)and EGR, which both include switch connections always get a bit sticky after a period of disuse, or in the case if the electric window switches, this can iccur if moisture seeps in.
I've heard that you can do this process through using a jumper pack with cigarette lighter wire so you don't lose ECU info and radio
no need for the tool or jumper pack, just jump leads from another battery works fine
maxthecaddy battery leads from another battery and connect to what?
That is handy. seen that in motor factors and didn't know what it was for but that's is handy ill get one and its there if I ever need to disconnect battery off some other car with no radio code.
Only think you forgot to mention is that the car live battery terminal remains live when the obd2 memory saver is connected and you have to ensure that the terminal does not touch any metal part of the car chassis
Tayna is where I bought my replacement battery last year. Good price and service. Good video as always.
You can change battery with the car running the alternator keeps life in the system
Thanks James, another informative video. Cheers!👍🏻👍🏻👍🏻🏴
Great job 👍 I use jump leads as I have them already and no need to buy anything else 😀👍
Bought a fabia 1.4tdi in December last year and found all your gearbox vids very interesting and now coming through with the goods again saving me a world of pain as I need to change the battery 😂
No need to buy a special tool to plug into OBD port. Just connect any 12v supply to the car at any convenient spot - many cars have posts for this. And put the battery sleeve back on. And code the battery to the ECU if required (probably not on this vehicle but the OEM battery did have the code on it so maybe it is necessary) If a new battery is not coded to the ECU it will die very very quickly.
What a neat little kit I love how easy it is to use I have never used one thank you for sharrig this on video
Ph in stoke
If you have the engine running and quickly disconnect the battery and fit the new battery, that works
I actually got one of those tools I haven’t used it yet ,thanks for the great information
Useful tool but I normally just hook some jump leads up to another car if I need to. I was under the impression that most cars are coded to the body computer so issues like this arise if you swap the radio to another car.
I could be wrong, it has been known 😄
Also, when a car has a decent battery box, I put the receipt in a large self seal bag and keep it underneath the battery, not lost one yet but the battery always dies after the guarantee.
Nice little tool to have, I haven't had a coded radio on a new car, must be getting on ten years now and that was a Ford Focus.
Look at that beautiful mk5 zetec s in black. It's just patiently waiting. Come on James.. please.. get that on the channel a full series..
Thanks for this. Very useful
Date of battery usually is on minus pole. It will have four digit code for example week 39 year 2019 (3919). Hope this helps. Great videos.
Nothing for ages then boom two videos. Keep them coming bud 👍
cool tool but why waste the money on it lol, jump leads or charger to the terminals on the car, take battery out and reconnect and bingo....
Plug your scan tool in and code in a new battery so it gets full charge all VAG CARS need this
I didn't know about these little tools - thanks
vag cars original radio codes are tied to the ecu, good tool for other cars though
same with honda
Hi I have only recently discovered your channel,Great Stuff man!! Just a word about Tayna batteries they come in at a good price. The issue is if you have a problem they wont replace it. I bought one with a five year guarantee it failed after nine months I sent photos, e mails, videos nothing worked. They want you to send it back so that they can test it and come up with a excuse not to replace it. It defeats the object I now buy locally if it fails just take it back. Hope your ok you've not posted for a while. Thanks Mike
Thank you for this video very helpful recently bought a Skoda Octavia need to change the battery radio code is missing so going to use your method
I used a booster pack and clipped it to the leads left it on while I changed the battery job done no codes needed!! good luck
Great video. You forgot to put sleeve back on though. Good to see your videos again. Keep going chap.
That’s brilliant James didn’t know they existed great tip 👍
these are a good little tool, I bought one recently [ebay, think it was a fiver] to change the battery on our Pug308, I recently had to change battery on my Grande Punto as well and I lost all the menu settings, was a right faff to set it all back up, didnt need a radio code though and strangely on that it kept it stations in memory. I seem to have a box full of various OBD2 things.
Over thinking it tbh ... just keep a set of jump leads attached and connected to a spare battery whilst removing from the battery terminals. Works the same and no need to faff checking you have a fully charged battery👍
P.S. think it’s been mentioned, but you forgot to put the Battery sleeve back on🥴
It's a good week when we get 2 Savage Garage videos
Might be very handy if I have to change the battery in my merc as supposedly you need to do what you did
Changed my kangoo maxi battery in November it was locked out thankfully code was in hand book putting in said code that was a different matter good channel for tips and advice 👍
😂 all those sauces!
You could buy a smart charger for car battery, almost same price and it has built in option for supporting all vehicle electronics when changing battery. Anyway, another interesting video..
My E70 X5 battery failed, it had been replaced by the previous owner at a well known high-street garage ahem... "SwiftFit" and they didn't code it to the car which eventually killed it. I found out that new batteries need to be coded to the car which was news to me. I miss the good old days of a 5 minute battery swap.
all vag and skoda have the radio code built in for that car dont matter if you disconnect the batter 12 times day that radio will not looz its code on the other hand if you take the radio out of that car and put it in another skoda then you will need you code its like peugeot and citroen have the same kinda setup you have to program it into the ecu
Interesting vid Jimbo
Great to see you back in action
When I changed the battery in my Audi A4 I had to go into the ECU BCM and change the battery’s stored serial number in the coding using a scan tool I think it’s to tell the cars ECU that you’ve changed the battery for a new one so the charging rate is reset I don’t know whether this is true it’s Skoda cars I thought you have a scan tool have a look and see if your has a battery update procedure ? As my VAC101 has a special option for doing this it’s called coding the battery
This is not a stop/start car so no battery management to be able to reset
Skoda and a majority of vws don’t require radio codes when reconnecting battery’s.
Some vehicles print the code with a bunch of others in the boot or other ID plates.
VAG batteries do tend to be pretty good from factory. My Golf's original battery lasted for 11 years. And yes that does look like an original battery to me. Both my golf and my dad's audi had the same type of battery from the factory.
Vw uses different brand names batteries
Like exide moll vera, but thats for sure an original battery
in poland we have online shop similar to ebay, it's called ALLEGRO there you can buy any radio code for up to 5 pound
Useful video but on a VAG car, the canbus radio knows its in the right car and will not need a code even if you physically take the radio out and put it back in again. It will however need a code if it goes into a different car
Renault and Dacia need radio codes on some models also cars with stop start can need an ecu reset when batteries are changed.
If it's factory stereo, yes it's a good idea to have the code BUT when i had my polo, if you disconnect the battery and reconnect, it will ask for the code but you can just turn igntion on and shut and open the drivers door and it will start working again
Good to know, i own a 2017 juke someone has put the code in the manual, good job pal 😁👍
Save your money. Connect a spare battery to your starter motor live and to a good ground, check the continuity with a multi meter, then change your battery.
Did you ever do the rusty wheel arches on the mondeo. I know you bought a welder, I was interested seeing you doing them.
May be you could use a trickle charger on the battery terminals to keep power to the ECU !!!!!
You're spoiling us now!! Two videos in one week 😁😁😁
Like buses, none for ages and then two at the same time.
Great little video James didn’t even know these were a thing
That's a great a tool but is much easier just to get a set of jump start cables hook them up to the battery terminals before taking them off and then hook the other end to a second battery or my case the run round then it's all good has to be done with Mercedes and any high end vehicles great tool though
helpful as always James, put the date of fitting on the battery for future reference
What about Fiesta videos? Are they gonna continue?
If it's all factory. The radio should keep the code stored in it's memory so when it's switched back on, everything should talk to each other and switch on. Mind you, I'm sure it doesn't always work, but I've never had an issue.
Its not just radios, its ecu’s too 👍🏻
Did you do the ecu battery adaptation using your scan tool afterwards?
Another great video, keep them coming. I enjoyed watching your toolbox tour ones again while you tube sesrching
Well you learn something new every day😃
Changed out original battery last month on my 11 plate Fabia. Didn't use a memory saver, radio not affected at all. Helpful vid though.
