DPF Problem

[Rok]

Dear all,

I am facing problems with my A6 avant ultra C7. 140000km At first there was constantly DPF light, and recuperation was much too often.. even i was doing 40km one way daily.

I check with local specialist and he was at first facing to unfinished recuperation.. but light apperas again after few 100km.. Then new error apera according to VCDS - Boost pressure regulator - we have install new one... and one week it was ok..  then DPF light apperas again.. few minutes later car was in service mode...…….. Few minutes before service mode i noticed low power..

Thank you in advance for some new ideas or approach...

Hi and welcome to the club.

If you have VCDS you can do a forced DPF regen. Ross-Tech have an How to

Hi Alan, Just came across this post. I have a similar issue where the EML has just come on today but no loss of power or anything. Although the AdBlue level warning came on today too, albeit just the 1500 mls top up advised so I've topped that up and cleared the EML and took the car for a short 15 min run keeping the revs above 2000rpm.

Beforehand I plugged in vcds and done a scan which came back with a fault code of "19226 Particulate Trap Bank 1"

                                          "Efficiency Below Threshold"

I haven't heard the car do a regen for a while now which I'm usually aware of and was going to do a forced regen but its not very clear how to do it on Ross Tech site.

Wondering if you can explain a bit clearer plz? 

Cheers

Hi Jim

Sorry for late response,

Have you asked the question on the VCDS site. I'm sure if you was to post a scan they would be more than happy to help out. Other than that I can't really help I'm afraid sorry. I don't have a DPF I've had mine deleted because of the known problems!

Lets us know how you get on, so others may learn.
