Hi Guys

Im trying to help a mate out, he has a fault which is not showing on a scan, but the interesting thing is his instrument cluster is not showing a rev or ser number during a scan and some weird text at the bottom

Address 17: Instruments Labels: 8L0-920-xxx-17.lbl
Part No: 8L0 920 980 A
Component: AB-KOMBIINSTR. VDO D07
Coding: 00444
Shop #: WSC 00000
VCID: 316EB3A7FBBF84C26A-5178

Component: AUZ7Z0X1156133
ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ AUZ7Z0X1156133
not see this before ????


He also tells me that his DIS stalk is not working so he can not see MPG av speed etc, he said he had the dash apart a while back but has only just noticed / been informed of the EPC light during his MOT.

I tested the lights on the cluster and the blub (as are all) are working as it lights up during test.

Could it be the Cluster has become uncoded?

Also of note there is no address 16 when running a scan.

Any ideas of a way forward would be great


Thanks in advance.

Probably your cluster is faulty (the 908 processor).
-Remove the cluster
-Remove the back cover
-hold a 60 second hot air to 908 chip ('MC908AZ60xxxx)
-put all back and connect the cluster and test it again, and see is there any difference or not.

Regards
