Blowing exhaust and engine management light has came on
topdawg:
Hi, i had a hole in my miltek flexi at the bottom of the downpipe, got it booked in the garage with no lights on the dash, got the car back today all fixed and on the drive back engine management light has came on, i was half expecting it to come on while i drove the car with the hole in the exhaust, but now that its fixed the light has came on, any suggestions ? can i reset it myself or it could be unrelated? any advice welcome thanks,
Andy:
scan the car for the fault qnd reset the light

Could well be due to the hole in the exhaust, as the emissions light does take time to come on. Could also be a damaged Lambda if they didn't remove/disconnect it first etc.
Scan of the codes is the only way to see what the cause is, as it could well be totally unrelated.

Yes i guess it could be unrelated but seems a coincidense that it came on on the short drive home from getting it fixed, anyway like you guys said scan with vagcom next, i messaged the garage and they said their vagcom is playing up and "We don't use vag com at the moment as our cable has decided to play up. If the exhaust isn't on the map and it's got decat it wouldn't usually just go away if reset
Some people space the sensor to give false reading to take the Light off" - to which i replied is has a sports cat, and also the car was mapped with thte exhaust on :s
