What service is required for a 1993 Volvo 940 Turbo

bulb failure warning relay has failed.behind your front ashtray last relay on the left .round one change it try on ebay.

It looks easy for the 940 but I am not sure about the 940 turbo, as maybe some of the turbo parts are in the way. I'm not sure about that, since there is no documentation on the turbo model vs. the 940 standard model. If you can follow the following instructions, then I would give it a whirl.

Any oil manufatured today will meet the requirments regaurdless of where it was made or where it was purchased.Here is a link to the owners manual.Hope it helps.http://www.volvoosad.com/Manuals/940_1993.pdf#190

I had a issue with my cruse control. Look under the hood. The the wire to the diaphragm for the crues might have popped off the throttle pully!

ok, this used alternator has bad diodes and will need them replaced. sometimes, certain technicians wont rebuild correctly. they just look over this vital part. i would return this alt.

The code seems to point to the camshft actuator circuit. Namely the Oil Control Valve. Probably needs replacement. I do not know the location on your vehicle. I suggest you ask a mechanic or try to find it online.

Sounds like you need an O2 sensor. You need to have it scanned, places like AutoZone will do this free of charge.
