    Hi,

    Our 2014 A6 ultra, with 105K on the clock, keeps posting a 19226 P2002 Particulate Bank 1 Efficiency Below Threshold fault code.

    The DPF appears ok on VCDS, both load wise and regular re-gens, and I have also swapped the two differential pressure sensors and re-adapted which hasn't changed anything.

    I've read that the EGR system, in particular the EGR cooler can become clogged over time and so would like to attempt to clean them out to see if it makes a difference.

    I've had a look on youtube and other forums for a guide but am struggling to find this engine. The HP EGR, LP EGR valves and cooler look absolutely buried by the turbo, can anyone offer any advice on how to tackle this job?

    Thanks

    Can you post up a photo of the location of the EGR?

    I've got a new EGR waiting to go in as mine seems to be causing me no end of problems. The Bank 1 error seems to come up almost every time. I've done some work on my A6 (also CNHA) myself but looking at this, it seems the cooling will need to be drained. I've got the workshop manual but it still seems like a difficult job.

    If i'm not mistaken, it's further towards the back and on the bottom half of the DPF. I'll see if I can find a picture.

    Cheers, the attachment link won’t open, but it might be my phone.

    Do you think pulling the arch liner and going in from the side might be the best route?

    I may be way off piste here, but could you have the engine Terracleaned? Would that help at all?

    To be honest I don't really know. Looking at the assembly from above, it could be possible to try and get to it from the wheel arch liner. I guess there is only one way of finding out right? I seriously think my EGR needs replacing as its causing all sorts of issues.

    Hey mate, did you manage to get to the EGR Cooler? I’m on the same boat
