Vag-Com results - What to fix first

[tobodestroyer]

Here is the result of tonight's Vag-Com test on my car...

The car has a slight misfire at certain revs and I'm suspecting a dodgy sensor somewhere - should I replace the Lamda a see if that cures it? At least VAG-COM proves that my car is a Nothelle N300

And lamba, service item after all

I have a known good MAF you could borrow for test proposes

I had the same errors on my RS2 but I save some money by following the VAG-COM faults guide on S2 Centralnet before changing MAF and Lambda....
I suggest you first check that guide and then after checking all the involved items proceed to change MAF or Lambda or both.
On mine it was broken pipe from the oil breather that had a crack in it so the motor was getting unmisured air in.
So I believe the logical and evil circle was this:
Lambda feels too much air getting in so it proceeds to increase fuel.....
MAF could not reach the mixture adaptation because it's over it's limit so gives error fault
Lambda gives error fault because it's limit it's reached aswell
hence two fault codes but eventually none of the above was faulty
I must pay a couple of pints to Paul sometimes.....

do a search for 561.
lots on that on here.

I'll borrow the MAF from my other S2 and see if that works. If so, I'll order a new one. That leads nicely onto my next question... where's the best place to pick one up at a bargain price? (I'd rather pay a little more and get a decent one).

Bosch agent by far the cheapest place - see the Bosch OEM part numbers sticky thread

00513 - Engine Speed Sensor (G28)

From experience, probobly a small red fishy thing.
