Just got my first Volvo today - '94 850 Turbo with just over 100K miles on it.
I'm very happy - I've wanted one of these wagons for decades. :D

Anyhow, there are a few things of concern. Rather than list them all here, I
was wondering the following:

On Jeep Grand Cherokees, there is a way to run a simple self-diagnostic test by
yourself with no fancy equipment. Is there something similar in Volvos,
specifically my model?

Oh, and is there another way to set the radio code besides with the number
buttons - my code has two "fours" in it and, of course, the 4 button doesn't
work. :/

TIA,
John in NH

That's nice, but what does this have to do with Rush?

For 850s up to and including 1995, see:
http://www.brickboard.com/FAQ/700-900/EngineOBDCodes.htm
Even though that's written for the 700/900 models, your 850 is the same

If your radio code has the number 4 in it, you need the 4 button to
work.

Well you could pull the radio, then remove the front panel to get at the
PCB and just use a jumper wire to short the contacts, it's pretty
straight forward, just two screws to remove.

Thank you but I see you have to buy something that costs about $100 to
interface with the car. In the Jeeps, it's a diagnostic done with how many
times the engine light flashes - was hoping there was something like that
"build in" to the Volvo's too.

Had to remove the button to get at/clean the microswitch. It works now. Any
place to get replacement buttons for the radios? :)

Then the website is meant for 850s after 1995. Up to 1995 the 850 had a
system similar to Jeep with flashing built-in LEDs. From 1996 onwards
the extra interface is needed.

There is, it's down behind the offside headlight. There's a couple of
sockets A and B and a jumper wire and an LED. :)

Yeah, pried it out to clean the microswitch and the button's pretty hacked up
now.

From the link I gave you, click on
"General Notes on On-Board Diagnostics in Volvo RWD Cars"
Follow all instructions for up to 1995 cars. Yours is exactly like
that, except the A and B boxes are up by the right headlight. No tool
needed.

If it's your first one, go to Alldata.com and spend $24 for a year of
detailed info on your car. Lots of instructions, diagrams, TSB's etc.
Well worth it.

You should have removed the whole front panel, it's not hard, two screws
and it unclips.
