PL: Error P2002 - AUDI A6 2.0 TDI ULTRA (190 HP)
 

Good morning,

I have an AUDI A6 C7 from 2014 with a 2.0 TDI ULTRA 190 hp engine.

Recently I have been confused by the error:

P200200 - Particulate filter, bank 1; malfunction
- Intermittent

The car rides normally, has power, DPF filter burns normally when driving. The filter is not clogged.

I replaced the differential pressure sensor with another one but it did not work.

Lamka sometimes goes out by herself after a few days, sometimes she erases it and immediately appears.

Can you help me somehow?

greetings

Did you get to the bottom of this? I have the exact same issue, and on the exact same year and model of car. Replaced the DPF sensor (and also the one in front of), and told the car to adapt when replaced both times, but the EML and code P2002 still returns - it seems to return quicker when the car is being used in sports mode. Any help would be appreciated!

I am in the same boat as both of you with a 2015 190 A6 ULTRA. I've had a DPF and NOX sensor replaced in the last month and still getting the p2002 fault code and CEL. Although mine refers to the Diesel Particulate Filter Efficiency Below Threshold.

I had a 2013 A4 previously and never had issues like this before so a bit baffled by it!!

I found the problem and fix it,contact if somebody needs still to fix it.

hi I have the exact same problem as of tonight , engine management light came on , the code was p2002 particle filter threshold below bank 1 , can you kindly inform me of the fix

kind regards

Hi,
its the egr cooler that you need to change,mine was really blocked with soot. To get this egr cooler out its really a big work,i spend almost 20hours to replace it.
Here some pics of mine soot egr cooler and the new one.

Hi, I've been struggling to get to the bottom of this problem for a long time so the fact you've diagnosed it is awesome!! Do you by any chance have a DIY guide or tips to getting to it and getting it off as the 20 hour jobs seems huge! Would be so grateful for your help! Cheers
