Hi 

I’m wondering if anyone can help me please?

I have just bought an Audi A6 black edition 67 plate 56000 miles from a reputable company

on my way home the engine light came on so I took it to my local garage straight away to have it diagnosed. And the code was P200200 particulate trap (bank 1) Efficiency below threshold. The mechanic asked how long it had been on the forecourt for and I know it came in in November. So 2 and a half months.

he said give it a good run on the motorway above 2000 revs as it could just be that so I did and when I next started it the light had gone off and has been off for 6 days but has come back on this morning. I’ve not had it diagnosed again as it is the weekend but I’m guessing it’s possibly the same issue I’ve contacted the company I bought it off and they have been great. They have told me to get it diagnosed again and get a quote for the work and it will be covered under warranty. 
I was just worrying I’ve bought a car with a serious issue or if it’s a simple fix?

any help would be very grateful 

Thanks Dan

Hi if they do it under warranty for you its a simple fix, if you were paying for it thats a different matter, its horrific as you have to remove the front of the car to get the cat and DPF out, I had mine done twice , the parts are expensive, I dont think the garage that sold you  the car have a clue about what's involved I did a fairly extensive description of it on the C7 part of the forum and all other members who own vehicles with the ULTRA system have had the same problems, A5,A6,Q5 etc, its a lousy design and if the fault is left the cooler ruptures and feeds adblue crystals in to the water system, thats fun, to be totally honest if I won another A6 in a competition I would have it up on Autotrader the next day the C7-C8 are money pits, what with the EGR coolers, stratospherically high parts prices for clutch parts and a dash light for every occasion I would definitely pass on another one.

I hope you have that in writing because it could be horrendously expensive.

Hi Dan,  

hope you got it resolved.

Could you let us know what the outcome was, and,  if there was success cleaning it  - how was it cleaned/fixed.

Seems there are quite a few ways to attempt to clean the DPF while it's still on the car?
