hi guys, I helped a mate with his 2.0 tdi Q5 tonight as he had error code -
P2002 - particulate trap bank 1 - efficiency bellow threshold
just as a bit of background info he had the glow plugs replaced last week, so not sure if any sensors are around them that could cause it, wouldn't have thought so but im not familiar with these and as much info as possible helps.
95,000 miles on the car and he has been on a good run and hammered it but not delved enough to know when the last one was.
I have done some digging and I believe this is what is required -
1. try to force a regeneration and check pipes to the filter
2. apparently someone else has a similar issue and replaced a g450 sensor and adapted it and forced a regen and this fixed it ( I believe they have 2 sensors)
3. if the above fails then the filter is beyond repair and requires a new/ second hand one.
anyone had this issue?
thanks for any advice
