Well, new fault has developed on my T5 V70 in the last few days.

Pulled out to overtake a car in 3rd, got up to about 5500rpm and was a huge bang and the car suddenly lurched forward. initially I thought the timing belt had failed or jumped a tooth! but it hasn't so that's some good news.

Being smart (arse), like I am, I disconnected the MAF (this has given me similar symptoms in the past) but the car still does it with the MAF unplugged. So I guess my MAF is fine.

So I did a DIM readout. frustrating I can't read the codes but the modules with faults are:

ABS ABS
SRS Airbags
ECM Engine Control Module
CEM Central Electronic Module
DDM Driver Door Module
CCM Climate Control Module
UEM Upper Electronic Module

I've highlighted in bold what modules I think are likely to be responsible. The only code I can pull with a generic reader is P1603 and it's not triggered but "pending".


Now, even when driving gently, it feels as though it's windy outside. like juddery.

I did have "STC Service Required" display and the STC disabled itself and put the light on the dash. It's not come back though.


Any clues? haha I knew I should have kept my 850!
