2.0 TDi Ultra CNHA EGR and cooler removal and cleaning

[Whippy53]

Go to Audi UK first, write a clear, concise, well reasoned letter and send it registered post. Don't rant, don't threaten just lay the problem out and ask for a response within a reasonable time frame. Have a talk to citizens advice as well and document everything. If you get no response then elevate it up the line. Good luck.

They don't know why this happened. Told me contact Audi UK. I will do but I think is wast of time. Maybe write to Audi Germany. Anyone can suggest to whom contact in Germany? A lot of people have this problem. Not only in UK.

What was the bill? DPF and Egr cooler plus labour you must be close to 3k .
Call this number 0800 699 888 and explain your case. Go from there. They're usual get out clause for this is your driving profile is not compatible with a modern DPF equipped diesel.
For comparison my car had 136k miles on it when I took out the cooler and dpf ( because audi tech notice says inspect EGR cooler first for P2002 faults) . The cooler was only slightly dirty , I changed mine because I didnt want to take it out again . My DPF was clear but reading close to 75% max ash so I got it cleaned while I had it all apart.
In the end my problem was the MAP sensor .

Payed £882 ( they discounted me 33%)just for cooler. DPF was ok. Car is running now smooth. Did you have fault with MAP sensor, or you just replaced it?

Replaced sensor due car going into limp mode every now and then.

Replace even no faults?
I can't find 04L 145 049 AE. Without AE there are but no with AE.

A mechanic with alot of experience on this particular generation of VW engine told me that if you have intermittent limp mode and a P2002 fault the first , easiest and cheapest attempt at a fix is replace the map sensor. After that go and look at EGR cooler and DPF.

AE would be the revision status of the part. Ask the parts dept at your AUDI dealership. I replaced that exact part number during the summer.

Just pop up info on my dashboard today 'coolant low level'. Need to call Audi garage. Never had this before. Start leaking after they replaced egr valve cooler.

Some very tricky limited access water pipe clamps down in that area.
