Any update on to what cured the issue as I'm having the same issue ?

I very rarely drive mine like that anymore 😂 I'm too busy looking at the fuel. Well I've spent all morning checking the intercooler system and all the hoses and they seem ok. Reset ECM and changed ambient temp sensor and still the same. Waiting for my cousin to come and check the electric side of things incase there is a split wire or bad earth so fingers crossed he finds something.

It could well be the wastegate and maybe its become free. Mine juts happened with no prior warning at all or symptons. I've got an OBD 11 reader and it's pretty good to be fair it allows you cycle through everything and watch live data so may be worth you getting one. Ive had 3 garages plug mine in and it always the same fault but as I've changed the MAF and MAP they are stumped and basically refused to look into it anymore ! Fingers crossed it doesn't happen for you again. A good "Italian Tune Up" may of fixed it 😀 Ive got to the point where I just want to find it regardless of cost. Then I can move forward. Its had the recall on the injectors and loom so hoping it's not them. I did and still kind of think maybe contaminated fuel has blocked up pump or injectors. Going down the rabbit hole though thinking of anything and everything !

I feel the same. Its like something is telling the car not to not accelerate but after 1500rpm runs fine. The fact that when the the MAP sensor is unplugged its ok is making me think communication from the MAF/IAT is out. Trying to get as much info possible before I dig any deeper on parts.

Cheers buddy. Mine has been like it since it first happened. I drove about 150 miles countless resets and still the same. I've just stripped the EGR cooler today in the hopes a good clean would resolve but still nothing. Checked all vacumn hoses and solenoids they seem ok so onto next job. My ambient temp sensor has been on the blink since I had the car 2 years ago. Goes from-20 to 40+ depending on its mood but has never gave me any issues as thought that it just controls the A/C but after some research today maybe its telling the IAT its too cold so the ECU is altering the air/fuel mixture. Maybe wrong but trying everything. If I ever find the reason I will.make the whole Audi community know about it as it seems like a common issue but with so many variables on what can cause the sames symptoms. Any others ideas or knowledge I'm all ears.

Hi guys new here and wondering if anybody has any advice as I'm pulling my hair out! Problem is I have Audi a4 Avant 2.0TDI 170 has been running faultlessly for 2 years. Taken a.over Europe etc. Coming home from Cornwall last week sat at 70 for 4 hours in cruise control on the motorway running fine untill I left then lost all power under 1500rpm. Thought i was in the wrong gear so carried on. Same on every junction! Managed to get it home barely (20miles or so) Thougt it would be a quick fix but am I wrong. Symptoms... very slow acceleration, it like massive turbo lag uptill 1500rpm then takes off. This is throughout the gears. Starts ok when warm but cold start takes a few goes and idles rough but then it's fine and idles perfect untill you pull away and it's dead. Have to ride the clutch together going and anticipate each gear shift and drop it down. So far I've cleaned MAF, no good so replaced for new one. Same. Changed fuel filter. Same. Stripped and cleaned EGR. Same. Replaced EGR. Same. Stripped and cleaned intake manifold and cleaned up swirlflaps checked to see if working on vacumn. Same. Replaced Boost pressure sensor as when unplugged its running ok just has the glow plug light on. Same. Changed it again for genuine Bosch sensor. Same. Checked wires and connectors on MAF, EGR map sensor. Seem ok. Same. Had it plugged in numerous times only fault code that shows is P0113 intake air temperature signal too high and P0238 boost pressure sensor signal too high hence changing MAF and Map sensor. Clear codes runs the same with no faults showing untill we start unplugging again. Had the AA come out. No idea ! 1 guy said EGR cooler but couldn't back up why and it's a big job to take on with no faults. Had one go on my caddy van and went into limp mode with code so had no issue in changing. I've spoke to countless garages and mechanics and it's stumped them all and they are all saying they can't help and would only do what ive already done. As no known faults show up apart form them 2 and the sensors have already been changed. Pulling my hair out now and I haven't got much left ! Is there anything you guys no of for me to check before I go insane ? I've ran some live data on OBD 11 and everything seems fine. I'm no expert but everything seems to be ok and In the parameters needed. Any help would be much appreciated before I start stripping and changing more parts to find the issue. Kind regards Andrew
