Did you have any luck then? I doubt the DP would have caused limp mode though surely?

Dom switched to Shark Performance as we don't offer a stg2+ on our own software, only REVO (which incidentally also threw EM faults on Doms car)

EM lights after tuning are common and are usually a sign of an underlying problem with the car rather than a fault caused by the software or a new part being fitted. A scan with VCDS should point out the fault that is causing the OP's problems.

I would have agreed with you, but Revo fault codes were engine running lean, caused by the first lambda sensor, new codes are the second lambda sensor with shark performance. I should have went back to superchips

000313 - Oxygen (Lambda) Sensor B1 S2: Response too Slow
P0139 - 004 - No Signal/Communication - MIL ON
004372 - Oxygen (Lambda) Sensor; B1 S2: Internal Resistance too High
P1114 - 008 - Implausible Signal - MIL ON

Just ask ben to remove the 2nd lambda from the map, have seen these before and was a faulty sensor rather than software issue so just deleted/adjusted the relevant maps manually and problem solved.

£600 - I would ask a bit more detail about what is required and what is being done.

matsu · « **Reply #22 on:** May 11, 2011, 02:43:14 pm »

these are thecodes it threw
p0420- cat effeciency below threshold- i take that as the 3" DP

p0121
p0221
p1545

when they download and re set it all...will i lose my map?
i,m going stage2 anyways -i just wondered.
ive known the owner of the garage a long time and altho he isnt a vag specialist-he is very thorough,if this isnt the problem- i wont get chaged for wrongly ordered parts!
and the labour is only 98 notes on this job!!

I think you'd be as well to go to a VAG specialist for this repair. I don't think the sum you've mentioned is correct.
