YAY! My car has thrown some codes!

[Tim]

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.

I kinda agree with you on the unmetered air thing. All the reading ive done in regards to these codes or similar ones seems to relate to steering away from it actually being the O2. If i thought it was that simple i wouldnt have posted up here!
Thanks for your input though. Im by no means a mechanic. maybe im a saddist but i kinda enjoy problems like this. theyre always a learning process

my car has just ticked over 220000kms. how long does an o2 sensor usually last?

just to put a spanner in the works around 120ks then they start to get tired if its the original one. Im like you mate i love the diagnostics mate.

[Tim]

yeah cant wait to get my new gti so i can start ripping into the VR properly. Just a bit hessitant whilst its my daily

[vwthunder]

Then Tim, you will have time to take the engine out and rebuild with a turbo

[Tim]

hmm new problem seems to be developing. I wonder if its related to the one i have outlined already.
It seems when my fuel guage gets to around 1/4 full the car seems to starve of fuel when going around left hand corners. The fuel guage is accurate as its still filling the same amount of fuel as it used to when topped up from 1/4 tank. Once I fill her up again she drives fine.

Could this be a fuel pressure issue? If so how could it only occur when the tank gets lower but nowhere near empty?

I did read that fuel pressure can relate to some of the codes i have pulled earlier in the thread.

[Jmac]

fuel pressure can throw the codes but you were getting two codes, 1 relating to high pressure and the other low. Mate sounds like your sender is out of whack from the start mate and you maybe lower than you think. Level doesnt alter pressure only if its too low you are running out !!! As you have 2 different codes relating to either fuel pressure issues i would say this fault isnt code related mate.

[Tim]

fuel definately isnt low. When i refill she only takes 35 - 40 litres.
perhaps its something to do with the fuel pickup then. Its just strange that its ONLY when i turn left as well. as the pickup is normally on the right hand corner of the tank isnt it? so unless my physics are really bad fuel would starve when u went right, not left!

[Jmac]

From memory the pick up is right in the guts?centre mate! Unusual mate, but not code related me thinks, ill have a pondern:

[Tim]

well the fuel starvation issue was an easy fix. When science and i were working on his car the other week we pulled the fuel pump from my tank and noticed that it had just been floating around in there. Must have not clipped it all the way in last time i was messin about in there and with my crazy driving it must have come unclipped somehow.

You looking forwards to getting your pump back tommorow?
