YAY! My car has thrown some codes!

**Tim** · 10-09-2007, 01:19 PM

My exhaust has smelt a little rich recently. especially on startup. So today being my day off i decided to have a bit of a poke about and give the car scan with the ol vag-com.

ive thrown the below codes. Just wondering b4 i start ripping into things if anyone has experience with similar codes b4? Im thinking of swapping out the O2 sensor with a spare one i have kicking about. The codes come back within a few seconds if you clear them.

I highly recommend Giorgio Locatelli: Pure Italian Very good show and the bloke is always on the piss

Mate check for split hoses/vac lines etc that can throw them codes. Watch the O2 sensor in measured value blocks with Vag com mate and see them fluctuate.

if i had a vacuum problem wouldnt my idle be all over the place?

Yep also you would be cutting off aswell!

Check those codes on Ross Techs site and also look for the explanation of fuel trim. I can't remember which way it goes but one form of the problem occurs at idle due to an air leak which the ECU cannot compensate for.

Ok then mixture adaption code 00561 is related to unmetered air. What is a vac leak??????? Hmmmm. G70 airmass meter also could be faulty and of course once again the lambda probe. Unmetered air also upsets the lambda probes. A sticky activated charcoal valve or too high fuel pressure also throws this code. 000537 also relates to unmetered air, or fuel pressure too low so it cant be that coz 00561 means it could be high. Back to unmetered air. Dont know how many times ive seen lambda probes fitted and there is nothing wrong with them, just because a fault relates to lambda it doesnt mean its the probe. The probe is reading what its getting guys, corrcet me if im wrong. When i was with Porsche the boxters were bad for throwing these codes and it ended up being a split crankcase breather hose (unmetered air) very rarely fitted probes unless they were old and tired.
