Can anyone help with part numbers?


Registered User
Hi to all,i have performed a scan with vcds and it has come up with 6 fault codes on my a4 2001 2.5tdi 180 q.
some i have managed to locate while others not:-

code 00553 (G70)
code 00523 (G42)
code 01441 (G210)

i roughly know what the fault is but i cannot find the individual vag part numbers for these components so i can simply just replace the parts

p.s. it also came up with 00550 check tdi timing what does this mean and how do i alter/check /test it?
Cheers Rob

G210 is the Fuel Level Sender - is this the same as the fuel gauge sender unit?

G42 is the Intake Air Temp (AIT) sensor - I think this is incorporated into the MAF but I'm not 100%.

G70 is the MAF itself - ETKA shows the Air Volume Meter as 059 906 461M

Cheers qj for the response,i have no idea if the ait is embedded into the maf or even if the fuel sensor is part of the float device,i've ordered a new sender for the fuel just in case.
Does anyone know where i can get hold of a maf sensor for reasonable money,a second hand unit will do but how can you tell if they are toast?
