Engine light after stage 2 with dp and cat **SOLVED**
Hedge:
Before recommending anything I would want to know what the actual fault code was that's causing the CEL.
It can come on for a lot of things but I drove around for several weeks on the standard map with dp and cat with no problems.
Once you get the codes post them on here and check http://wiki.ross-tech.com/index.php/Category:Fault_Codes.
Aparoon:
I have just got the codes using my bf handset (v useful), they are p0139 and p2195, they both relate to the os sensor :happy2:
Poppa Dom:
Could be that a new sensor is in order if that is the case, but I am no expert.
Hedge:
I think I would be speaking to whoever fitted the exhaust.
Janner_Sy:
the guy who i bought my pipewerx exhaust off had the same problem also using bluefin stage 2.
ill find the link for you in a bit, but i believe one of the sensor bungs in the exhaust was blanked off for some reason which pipewerx explained and he drilled it through, solving the problem
