UK-POLOS.NET - THE VW Polo Forum

Had My 6n2 GTi on vag.com and the following faults came up. Ive got The exhaust emission check light on by the way.

16514 - oxygen (lambda) sensor b1 s1: malfunction in circuit

16556 - fuel trim bank 1 system too rich

16517 - oxygen (lambda) sensor b1 s1: response to slow

16555 - fuel trim bank 1 system to lean

17511 - oxygen (lambda) sensor heating b1 s1 : performance too low

17927 - camshaft adjustment bank 1 malfunction


What parts you reckon need replacing to get rid of these?

Cheers Dan

I've had a look on the Ross-Tech Wiki site and it seems to be that most of the fault codes are relating to the Lambda sensor.

The causes of '16555 - fuel trim bank 1 system to lean' is the Mass Air Flow sensor.

Here, have a look for yourself Ross-Tech Wiki!

Sorry, I haven't been much help.

6n2s dont have a MAF lol

Thats a problem with the lambda sensors for sure - check the wiring underneath the car.

nice one cheers mate
