That was a good check on a car with no fault codes, nice explanation on why you see higher air flow on a diesel than a petrol. No power due to a choked air filter, nice find.
I'm only 4 mins in... I like the thought process. Good call on questioning the customer further, this does eliminate the MAF or IAT, as you stated. Nice to shorten the code list..... Continuing on....
Interesting info regarding the diesiels. As you're probably aware, we in the states don't have as many diesels as you do there. Even though I have done work on a variety of diesels, I am more well versed on petrol/gasoline driven vehicles. I appreciate the in depth coverage. You make it easy to understand (once you get passed the accent. 😅😂😂 just kidding). Thanks Dave! 😊🤗🤗 Oh I enjoyed the use of EricO's line "giving it the beans". 😉😉
So glad you enjoyed it cuba. I know my accent can appear strong tho i sometimes deliberately adf in some Norn Ireland slang which only locals may understand. Give it the Beans - Keep her Lit, cheers dave
Dave I have the same car, has big miles. It is sooting the dpf (and cat). I have noticed that if the Intercooler is disconnected it basically dies; is this normal? Could the intercooler be so blocked it need the air pressure of the turbo to run? or is this normal in the M9R engine? Let me know if you can. Fantastic video, learned a lot. CHEERS ;-)
Your point about checking the simple and basics first Dave is well taken. Would be interesting to see a side by side before and after graphs of the mass air as the RPM increases under load. Would the restriction cause a linear error in MAF or exponential as RPM increases ??? Buggerized MAF figures reek havoc on the calc load as you well know...spoiling the broth! Great Vid Dave. Cheers Pal
Yes ian absolutely. The before and after would have been a lot better on a test drive as the symptoms were on load. But, i have to press on as im sure you appreciate. Added the wee explanation bit in this morning, cheers dave
dave sterl Oh I totally understand Dave. You got a life to live. Just thinking out loud for what might make for interesting viewing. I have tons of ideas that never surface because of the practical constraints. As I said...great Vid 👍
Just goes to show , sometimes, back to basics , technology helps to point using the right direction , a case of vehicle strangulation if ever there was , no air, can't breath , just like a diver, let's hope the customer follows your advice, full service, and another customer, who will recommend you to all their friends and family, and the other person who wasn't maintaining the car will loose business, good job !!!!!!!
@@davesterl because the shitester who worked on it before has been ripping him off , good diagnosing is priceless , that's why we work doing what we do , too many people in our job just like to fit expensive electronic components, £8 air cleaner element , so easy to change , why did the previous garage not change it ?, What else did they not do ??
Absolutely delighted to have Davy dealing with my car. To be honest I really didn't appreciate the amount of miles I was doing a year. I had it serviced 24,000 miles ago and had an oil change in between. Thankfully this is a very valuable lesson for me. Full service getting done and a couple of extra things that Davy discussed with me. It's great to have a car investigated and diagnosed instead of just throwing parts at it. I do and will continue to recommend Davy. A pity you didn't live a bit closer, but hey going by this it is worth the journey. Thanks Dave
Was made up with this video Dave . I had this a while back on a fella s diesel freelander , he told me it had been serviced but looking at it things didnt seem right . Eventually after a bit of head scratching I thought I wonder what air filter is like and Bingo it was as black as a coal miners hanky . on roadtest it was a different vehicle once we removed the noose from its neck lol . Now and again we touch lucky with a cheap easy fix . Regards Rich
Thanks for sharing the video Dave. These can sometimes be the hardest complaints to track down, I think It’s easy to over think it, and head down the rabbit hole in the wrong direction, when you just need to check the basics. Lord knows I too often find myself down the rabbit hole, lol. Are those the Hantek breakout leads? If so, do you like them? I have some of those on my amazon tool list. I can’t decide if I want to get those or spring for the fancy kit from AESWave. Anyhow, keep the videos coming 🤓
Cheers Dave good tutorial on a diesel, must admit never thought about massive difference in air mass figures between petrol and diesel, well spotted and explained cheers sandy
Glad u liked it sandy, got a 26 minute video out of changing an air filter. Only kidding it al happened the way i showed it. Not quite sandy mendes yet tho. Cheers dave
Does anyone have a problem on a Nissan Qashqai 2.0 dci, that the revs drop, and immediately come back when you press the clutch, and it only happens when the car is cold
Hi Dave, i have a 2.0 volvo diesel at WOT i only have 180g/s it looks a bit low to me do you have any input about after new filter how many g/s got at max???
Well remember COMMON SENSE IS NOT SO >>>>>COMMON !!!!!! plus remember people who shop MECHANICS... aren`t well liked so there a pain in the ass more than any thing

The power of basics and knowing what to check well done Dave thanks for sharing
Cheers ian, not that easy when youve not much to go on, have to check everything
That was a good check on a car with no fault codes, nice explanation on why you see higher air flow on a diesel than a petrol. No power due to a choked air filter, nice find.
Chees matt, its dead easy when you've found it, as I'm sure you can relate to
The scream at the start scared me lol
Nice and simple, no spanners needed.
Yep, got it before the spanners came out, cheers dave

Top work Dave great thought process 👍👍👍
Very interseting regarding the throttle body or intake valve, cheers Dave.
Glad u liked it Colin
Love it Dave
Thanks
Great stuff dave.... and wow...that air filter...... holy crap.....
In the old days, air filters were only for people from the Malone.

Yeah Rich, kicked myself a bit on this one too. There's that many things we are thinking, we then skip the basics cheers dave
Mad, thanks for the info.

No probs Atom, yes overthinking all too often and they are indeed the hantek breakout leads which are great for the price
Nice fix mate
cheers Leon
Thanks for this, would a leaking vacuum pump cause P4088 erg valve issue ? Thanks.

@martinguitarhd28 glaf u liked it Martin
Nice explanation.
Morning,please can you assist with 2.0 dci it doesn't have power.
@@PietNoyo-fh6tz not much I can do from here

Sorry mate, i didnt record any wot readings on the tool. Have a look at the video when i rev the car might give u some info
Have you had any issues with these throwing a fuel pressure regulation fault up Dave?
Not had that on these but you can get that problem on any modern diesel
It randomly looses power and cuts out,the fault codes I've got are p0089.thanks for your reply
What about yeeeee! hahaha love it.
