Bonjour, L'une des plus belle vidéo que j'ai vue Non toutes vos vidéos sont belles a moi que celle-ci est unique, J'adore votre façon de diagnostiquer d'ailleurs vous ne savez pas combien j'ai tant attendu la 2ème partie pour voir la fin du diagnostique Bonne continuation monsieur

My 2011 golf tdi has similar mileage right now, but mostly freeway miles. At around 224k miles it died on me. Then it would crank, no start, no codes. I had another car so only worked on it on my free time on and off for a few months. First check for hpfp failure, no metal specks. Pull the top of hpfp apart verified piston and check valve.Replace fuel filter. Specified and actual fuel pressure was good. Check fuel pressure from lift pump and aux electric pump. Check injector timing with scope and relative compression. Check ASV with the output test and removing that hose. Check timing and it seemed okay, replace timing belt, water pump and coolant anyway since it was due. Tried Priming the fuel system many times. Then I read about and tried removing the piping to the egr valve like you and it started. Checked the exhaust valve and it was working. Finally remove the intake pipe to the turbo and found that it failed and the compressor seize stuck to the side of housing preventing the impeller from turning on the exhaust side. It was pain to replace the turbo, with the help KZread channels like yours I was able to diagnose and finally repair it.

Great video of looking into how diesels work by air and how important it is on diesels could you of looked at dpf pressure senser and seen if that was reading high I presume it's got a pressure senser for dpf

Just picked up a 14 tdi with about 110k on it. I've put 2k on it and it's been running perfect until.... today i went to start it and it turned over then nothing. Flashing glow plug light. Tried again after work and it idled a bit then died. Did this several times. Thanks for the tips in this video, wish i lived closer to Kansas city! 😂

wow that a good one ...neven seen that before engin that stop running after 5 sec ...so diesel need more air than gas engine make sence because they have more compression ratio than gas .thanks for video love it

Cool diagnosis, so it looked like there was enough exhaust released thru the EGR pipe to allow it to run .. it kinda ran poorly but know I can see why. Would love to see how to remove and reinstall a new DPF. So what is the fault on the ECU from the DPF? How is that triggered? Is it a pressure differential sensor if there is inlet pressure to the DPF does it throw the fault? Great job guys 👍🏻 I have CJAA that’s running bad right now in ‘13 Jetta I suspect it’s related to to that filter

I like long learning ..i had a dpf issue. Had a rebuild by dealer for my 2015 diesel manual tdi...and had issues for the regeneration

one of my newest videos shows problems that might cause no regen. But there are lots of stuff that can do that.

This is another cool methodological diagnosis. a viewer like me wouldnt mind if its more than 15 min long. but do as you need to please your algorithmic overlords 🙂 this reminds me of the time my wife drove my 2001 civic and while on the freeway and it just stopped suddenly dead on its tracks while doing 65. it wouldnt even turn over no matter what. In the end we found that the catalytic medium had melted solid (probable cause was rich or lean fuel mix) and because of repeated starting attempts, we also broke the boss on the block that held the timing belt tensioner. fun times. got rid of the car soon as i rebuilt the engine.

My 2011 tdi 1.6 same problem. Started with glow plug indication on the dash. Diagnostics tool brought up " fuel injector circuit but all 4 gave 12v. I have replaced all 4 glow plugs. But still same issue. Wants to start, sounds normal but it just wouldn't start. Before that the engine ran but sounded very rough. Now its just not starting anymore.

no 1.6 tdi's here. So I have no clue.

When did they last change their timing belt? I had a similar problem where the car would start then stop. A few months past and my timing belt came undone and caused interference

That’s was a great who done it 👍

Does the scantool show rail pressure, MAP, MAF and DPF pressure? Unless the refresh rate is poor, it will give good direction on what needs testing

Hi sir i just want to ask you a question even though it's not related to this video a guy had an issue with the tsi engine blowing white smoke from the exhaust and it has something to do with the fuel pump however he doesn't want to explain more please if you have any info on that i will be glad to you thank you

Good video for learning purposes! Maybe it was "FAST" if you measured the differential pressure on the DPF with VCDS. I'm sure it was a big one given the fact that there was an error on the DPF!

Yes, but when you've never had clogged exhaust a problem like this you dont know. But if your methodical in your diag process then you find the problem anyway.

Not trying to sound like “that guy” BUT water in the intercooler line, will indeed, prevent an engine from running, AKA Hydrolocking..Unfortunately, speaking from experience. Ran for a few seconds then shut-down. Unlike your issue but worth noting.

@CoolAirVw

Жыл бұрын

Eric. Water in the bottom of the intercooler will not hydrolock. Water from the intercooler that passes into the engine will make hydrolock. Your splitting hairs with semanitcs like "that guy". But I understand what your saying. I have a video on intercooler icing. If the water is frozen entirely it wont pass into the engine till it thaws. Partial blockage by ice will not make the engine not run. Full blockage by ice will make start die situation then when you "thaw" the vehicle, if there is enough water to pass into the engine then it hydrolocks.
