can anyone recommend a code reader for my 94 850 turbo? it apparently
requires the OBD1 interface
and I cant seem to find one that works on a volvo
One of the better things about the 94 is that you don't need a code
reader. Look under the hood, on front of the computer housing. Two
connector blocks, A and B, with a wire, LED, and button.
To read the engine codes, plug the wire into A2, and press the button
once. Watch the flashes (3 times, pause, 2 times, pause, 4 times =
3-1-4.

Press it again, and you get the next code if there are more than one.
You can also use it to clear the service light.
One good source of info is here:

If you plan on keeping the car for a while and maintaining it
yourself, I strongly suggest getting the excellent factory service
manuals, which contain troubleshooting procedures for each code.
If you have the original paperwork, there should be an order booklet
for the manuals. (They used to be available via their website, but I
can't find the link right now.)
(Note, the manuals and code data aren't available to owners on new
models, which is why I own an Audi now.)
