940 dash lights instruments fault, help please

undertaker · Nov 9th, 2010, 18:23

Hi, my 940 estate 96 has developed an intermittent fault where the speedo, tacho and fuel gauge stop working, and the oil warning lamp glows while running. The car keeps going normally but i get a feeling the turbo has failed too when this happens. If I stop and switch off and ignition back on, most of the warnings are missing except for seat belt and indicator warning. Any ideas please? I had a front off side indicator blow earlier today and changed that but can't imagine it can be connected to this. I checked all fuses and wiggled all the relays mounted behind. The problem disappeared but has faulted again several times since. Thanks folks.

Hi,

Sounds suspiciously like the ignition barrel playing up. Details on the FAQ:
