Great advice. Makes sense for the EGR gasses to be directed downstream rather than against the incoming air flow. Sorted mine 100%. Thanks fella.
You've helped me with my timing chain on 1.4 tfsi and now this on my sisters 1.6 tdi. Absolute legend!
Glad i could help. Thanks for your feedback
@@FourRingsAuto only if you were local to me. Youd have all my wallet ahaha
Great advice. My 2013 tiguan tdi has 445k on it. Never had throttle body scrubbed. Will do this tomorrow. Thanks.
I think you have just solved my problem because my throttle sticks open and its bloody annoying and I have an egr code so will give this a try cheers mate.
Great video thanks! 245,000km before the first issue
Looks like mine is stuck it will only partially open
Could be broken plastic gears inside.
It was odd the gears were in great shape but there was residue preventing it from opening all the way. When I turned the gear by hand I got it to open. Then cleaned it with some foaming degreaser and worked some white lithium grease into the mechanism - ran an output test with the vcds working again now :) lol we will see for how long haha thanks again for the vid.
I know its an old vid, but omg I'm so happy I found ur channel. Obv am now a subscriber :)... Ive an Audi TT 2009 2.0TDI CBBB engine and while am still learning about this car these vids/info you provide am sure will be a great help should I run into this problem in the future. Again much appreciated for taking the time as I love my Audi, though I wish we had the Sun in the UK u guys have, as its the Roadster version which spends most of the time roof up grrrr... Lots of love to u guys xoxo
Could you do an in depth video on removal and reinstall of the throttle body as would love todo this myself and not pay a mechanic a shite load of money
Removing the rear bolt took me absolutely ages
@@jonmyers74what did you do to get it out?
I have the same code on a golf mk6 2.0 tdi cr cbab engine, uve also got tyre pressure warning light on dash and glow plug cylinder 2 code
would turning the nozzle 180 not make it block quicker ??
Excellent - well done! 2009 Passat CC (2.0L TDI) stalled at an intersection and was just dead! Had it towed to a workshop - I believe it was the throttle body (or technically ASV valve) that was stuck shut so no air to engine?! Workshop cleaned it out but said I would need to get a new one installed later - $$$! I understand the circular gear and semi-circular gear in the body of the valve also wear out prematurely (due to turning the flap coated in all that sticky carbon). I noticed that X8R in the UK sell a kit with stronger carbon-fibre reinforced gears for the DIY mechanic - what do you think of this?
would flipping that valve cause any other issues like the manifold clog up
It looks like the car company deliberately point the EGR intake toward the throttle instead of the engine. What was the purpose of that? Maybe to have a better mixer with air?
Coz i read somewhere the diesel engine does not need calabrating only for petrol engine
My car has done this engine light on permanent glow plug light kicks on goes into limp mode. My friend is taking my car next week for a stage 1 remap with the egr delet that should hopefully resolve the problem
Is throttle body fault anyway connected to the flywheel starts rattling when motor shuts down?before problems with throttle flywheel were not making any sounds?
Once the throttle body has been cleaned. Do I now require to calibrate the throttle valve, or will it learn itself now there is no blockage? Does it need it? And if it does what methods are available for doing so? I gather you can get software to interface with it but have also read about various forms of foot in peddle and turning the ignition on and off.
VCDS by Ross Tech from USA. It should have it's basic setting reset, but it'll probably still work witout.
Great video, thanks. Is it prudent to clean the pipe work you removed to allow the removal of the flange plate prior to rotating and reassembling?
It would be best yes.
Very helpful. Thanks for this video
hello, where do you have to look at the opening of the valve of the tube up or down where the butterfly thank you very much
If i just blanked the egr pipe would that throw a emissions light up
I'm having lagging issues with my car. When I unplug the throttle body the issue goes away? Can someone explain?
Ese cuerpo de aceleración puede dar fallo P2015?????
No engine light on my 2006 SDI Golf. I scanned codes and 2108 came up.
Hiya. My 2016 passat. Has thrown up a P048C code. Looking at other TH-cam videos and your own. It seems to be a similar issue, to the one you're showing and talking about here...
How did you get the actual valve off?? Doesn't seem plausible on mine.
Watching your vid. I may have messed up, by dowsing the valve in penetrating oil and wd40 (in the hope, lubing it up, would undo the seized valve) hopefully not.
Any help much appreciated.
I bought a new tb and plug and still have 123code an 0202 code
I have cleaned it once, after how many kilometers I have to clean it again, and now what it does is when I turn it off it rots it does not turn off smoothly. is it from it? Thanx you
I wouldn’t rotate it as I’d rather have to clean or replace this part which is easy rather than what your doing feeding all that carbon straight to the intake won’t be so easy cleaning that and off your valves.
Clean and leave how it was or block off the egr and have it mapped out correctly and you won’t have this problem again.
On the same 2.0 to ,I have just had the throttle valve cleaned , should I be thinking of having the egr valve cleaned and can you show how to locate and remove?
Is it something I could do myself.
Egr valve on the later 2.0tdi are on the rear of the engine with the cooler. From memory they aren't sold separately, at least on some of the variants, as i have seem them fitted with tamper proof bolts into the egr cooler assembly. A pain to replace especially as a diyer. Leave it until you have an issue then have the valve and cooler sonic cleaned.
Could you possibly point me in the direction of the official VW modification statement
Create an account for VW Erwin online. Pay the €7 for an hours use and you can find the TPI relative to your VIN number.
So to confirm, you suggest flipping the recirculation pipe so the EGR gasses go into the intake instead of the throttle unit?
Yep. And that's from the manufacturer, not just "my opinion".
Why is this though? Just curious.
@@AJ-ex8psa year late but I just did this , intake is farther away from where you can’t have debris going into and it’s also way easier to clean than the tb
I've replaced mine but still get the error code p2108 and the car huggers at high rpm, any suggestions?
Hi thanks very much for the vid,this fix worked a treat initially, but I am now getting the flashing coil again and the engine light with error P0403 which relates to the EGR valve. Do you have any idea if there is a link to the original fault or any hints on what I could try please? I checked the price of a new EGR valve and I am quite stressed as they are almost £250. Thanks in advance!
Hi i have a audi a4 b7 2.0 tdi 2006 when fitting a new throttle body do i need to calibrate it thanks
Why rotate it ? So essentially it will by pass throttle body. So what action will throttle body have then ?
Is it worth doing this if fault not shown yet? Had an egr fault so got it replaced with a walnut clean on the engine. It was replaced 10,000 miles ago on a 2011 with 90,000 miles on it???
i have removed my throttle it was cocked up that bad, but i noticed its getting stuck at the closed position sometime? also is there any way to test this because i plugged it back in to the connector plus whilst off car, started car, nothing happens to flap when ignition on,, nothing when i rev it engine, ,....is it faulty ?
How do I Rev the engine from the engine bay?
I have problem for golf 5 tdi my throttle body is open so there's no electric in throttle no power in my car pls pls help guys
Ciao mi dire dove si trova il sensore map su un motore cffb audi a3 8pa anno 2011
I have replaced the egr valve and throttle body and code p2108 code still comes up
Same with me. New one on and code still there?
@@jasonsasmanGTR how did you fix the problem after all?
Glad I'm not the only one
Does this cause engine judder / stutter around 1500 rpm on a 2012 2.0 tdi ?
The egr on my mk5 bkd tdi has been mapped out, I'm getting a shudder when I turn off the ignition. Will cleaning/replacing the throttle body help cure this problem?
hello im having the same problem, did you by any chance fix it?? please reply
When the inlet valve is turned to face the other way does this just not cause a problem/ clog further up stream. In the manifold etc
There's always going to be carbon build up, but when it's the wrong way it's hot air meeting the inlet air and forming on the throttle. There's nothing extra going to happen. This is the manufacturers recommended rectification, all other of their diesels are facing the inlet.
A4 B8 2.0 TDI (CAGC) - I have rough idle (engine shaking badly, seems to work louder, noticeable vibrations inside of cabin), rev gauge is not fluctuating, rough idle happens random, and after pressing acc. pedal for few times or driving for a short time it becomes normal... does anyone have any idea why this is happening? I need to clean EGR valve (i think it is dirty), i tried to clean "throttle body" myself long time ago but later on i've read that butterfly plate inside is not good to touch or push, and i was pushing and releasing many times while cleaning, it is possible that i damaged my TB ? Also, i noticed engine temperature gauge is reaching 90 deg really slow and if i turn on heating it goes back to 70...60... degree.. I used vag-com to check high pressure and it is fluctuating it seems... no errors!
Did you find out what was the problem?
You are describing exactly the same thing that I want to figure out what the problem is.. With shaking and giving gas a few times and gets normal. The same thing with the Temperature, but in sommer it reaches 90 degrees. I was thinking to check the tb or maybe to replace TB because it's not so expensive about 80€. It seems that it's the common and design issue on this type of engine.. No one knows what it is it seems
I just had the throttle body replaced on mine. Let's see if the temp goes up to normal now. Haven't tried rotating the flange but that will be next.
Not getting up to temp is a thermostat related issue. On transverse DSG cars it can be tested by clamping the oil cooler coolant hose to the dsg. There is a thermostat in the hose that fails.
Do you have a video that shows how to take the throttle body out? I have a Q3 2.0 tdi that is showing PO121 and id like to try this but can't find any guides.
No sorry i don't think i do. I moght have one in my "to edit" folder of videos. I will have a look if i have time on the weekend.
Hi, thanks for the video. How did you manage to get the pipe connected to the throttle valve off? It looks like in order to remove the valve, the piping needs to come off but the bottom circlip is incredibly hard to access - im struggling to find a tool that can fit in that gap and allow me to loosen that bolt, which seems to be a hybrid 7mm bolt with flat head screw slot.
I'm working on my 2014 2.0TDI 140 Tiguan and the clearance between the throttle body and radiator fan isn't great....
@@FourRingsAuto thanks for the reply. Might give this a go over the weekend. What tools do u need to take the throttle body out?
Outstanding many thanks
There is any video on how to swap those plastic gears inside? i thinkmine are broken, I have an error code: P2108.
Sorry, no i haven't had to repair one of these yet.
Just take them out and slot the new ones in. But it could be the motor which is dying also.
i have 2004 audi a3 tdi i put on new throttle body and when go to adaption it says no communication
Have you tried exiting the ecu and going back in? Do you have a genuine RossTech VCDS cable or eBay one?
thanks for the video!
Thank you for the video. I have a question, changing the gas direction from throttle valve to engine intake, will not affect something else in the feature? Like injectors or something else? I want to mention that i dont know much about cars...
No issues. This repair is recommended by VW Audi under one of their technical bulletins.
@@FourRingsAuto can you indicate the service bulletin name please ? I'm having a hard time convincing my mechanic it's worth doing this...and by indicating the name I'm sure I will gain more credibility. Thank you !
Well if your mechanic is not a vw audi specialist then it sounds like he is not worth your time. If you have to convince him otherwise than what i have shared then you're better to go elsewhere. This is a factory advised modification.
@@FourRingsAuto problem is that finding a propper mechanic is very hard these days, especially where I live. He actually repairs a lot of VAG vehicles and untill now he's been pretty fair play but he said he couldn't find the TBS about this...so I was hoping to make use of your knowledge and share it with him...
What country are you in?
Thanks for sharing!
Great video, I am about to tackle this on a skoda superb mark 2, 2.0. 2013 , do you reckon it would be same process and would the throttle body need to be recalibrated afterwards? Cheers b
If it's the the same setup 2.0tdi then yes. Only difference on different models is the clearance against the front of the car when working on the throttle and removing. Yes it's definitely gonna be advised to do the basic settings afterwards.
Once turned 180 degrees back into the manifold, is there anything risky toward the engine when this is done
No. This is advised by tue manufacturer. It is where it should be facing.
@@FourRingsAuto is it same for Golf?
hey mate, great video. my question is..can that flange be rotated wihtout putting the notch in?
secondly my car is a skoda superb 2.0 tdi cffb engine 2012. last week it clonked out on me at a junction, wouldnt start. got it started with easy start and ran for half a mile, and done it again. and now will only start with easy start and run fine...i go to drive it and 100 yars or so, it will eventually sputter and cut out when i try to rev it. do you think the throttle is clogged or stuck? i noticed when i used to put my ignition on..my car would make a electric motor type noise for a few seconds but isnt doing that now...that that the motor engaging to close the throttle to allow car to start?. i cleaned it last year approx 8k miles ago but i only do short trips. surely it cant be clogged that quick?
Check the in tank fuel pump
@@FourRingsAuto i cleaned this throttle, and it started off its own power, no easy start needed, drove it 4/5 miles and didnt clonk out so i think its fixed thanks. i will next do the rotation of the valve thing you showed
Hey, do you need to re-align the throttle body using software like you would in a petrol engine ?
It is good practice to carry out a calibration yes. It isn't quite as issue as it is with a petrol though. However, yes it should be done.
as long as you dont move the flap it should be fine
Do you have the bulletin for the EGR fix?
Google vw Erwin or audi Erwin depending on brand. Create an account, pay for 1 hours use and put in your vin number. Will give u all TPI TSBs for your car and full workshop manual.
I did this and me EML light came one code P0405
If you have this same setup and p0405, the egr valve is built into the cooler on the back of the engine, below the turbo. Check there isn't any coolant coming out around it, as the cooler can leak into the egr valve. P0405 is an egr electrical circuit code. Sounds u related to this repair to prevent the throttle carboning up.
When you remove the ASV ("throttle body") do you need to replace a gasket?
It's rubber so usually can be reused. Ideally you'd replace it but they usually still have a good profile.
@@FourRingsAuto Thanks!
If there is a reason why this problem and the glow plug controller fault come up at the same time?? Are they related or is it simply because the P2111 turns MIL_ON?
I wish someone could answer this question above,
I have the same problem atm and would like to know why the glow plug light flashes and engine light on at the same time , on the dash .
I scanned DTC P2111“throttle actuator stuck open”
Is there a reason for this?
@@mordialloc1 the electric motor brushes wear out and the motor eventually stops working. The valve stays open if the motor does no make it move.
@@andrert2178 thanks for the explanation now it makes sense why the throttle is stuck open. That brought up the engine light which I believe is caused by the DTC P2111.
So I’m still curious isn’t the flashing squiggle light supposed to be a glow plug light?
@@mordialloc1 on vag cars at least, the glow plugs flashing is used to indicate that some system is preventing other systems from working. in this case indicates that you won't have for regeneration because the throttle valve not working makes the EGR stop working and without functional EGR the diesel particulate filter regeneration is not initiated by the control module. The throttle valve is used to regulate the flow of exhaust gases that are required to recirculate during normal driving but particularly during dpf regeneration.
@@andrert2178 Mate, you’re a legend!!
I have sound knowledge of petrol engines but new to the diesel engine and it’s operation.
Your answer has me on the right path to fixing it.
Many thanks 👍🏻
Wow that is filthy
Is this the same as the 2.0 PD TDI?
Nope. Different setup entirely.
I dont get it. On most of websites i see it say that diesrls engine have no throttle bodies
That's because most websites are full of people that don't know about cars.
Modern diesel engines have throttle bodies, I don't care what anyone says as they're there. Some call them anti shudder valves or shut off valves as that was there use early in 90s maybe. But it is actually used now as a throttle during EGR operation to partially throttle the fresh air intake and pull more exhaust gas from the open EGR valve.
What engine is it? 140hp version?
From memory, yes.
@@FourRingsAuto do you have any experience with the 110hp version? Are those reliable because I have a skoda yeti 2.0 tdi 4x4 110hp (enginecode: CFHF)?
Maybe better to delete the egr
So where is this locate
Ask your mechanic
