I was driving recently when our dog (who was sitting on my wife's lap) pressed the W button on the console with his foot for an extended period of time.

The car went into emergency mode (not sure what it's called) but it wouldn't go above 25 mph's and we were able to limp into a parking lot about 1/4 mile away.

I turned off the W button, but the check engine light came on and is throwing the P0700 code.

I tried clearing it with my ODBII scanner but did not have any luck.

Any suggestions on clearing this? Or if this is a problem that needs immediate attention?

Car runs great otherwise.

Thanks in advance.

 

2 years too late. But I spent $50 on this gem from a Volvo specialist.

P0700 (Generic transmission code) - Again no symptoms. No problems shifting. No problems with rear lights. Up arrow flashing light appears but again, no transmission issues. No limp mode.
Option 1: Remove battery for an hour to clear code.
Option 2: PNP switch replacement or cleaning
Option 3: Tranny replacement
Option 4: Shifter row. I rowed the shifter while the key was in Position II. This did nothing.

SOLUTION: This one was the one that I was really pissed about. If you don't have any shifting or obvious tranny problems or reverse light problems, look at the W button next to the shifter. Mine was stuck slightly and thus, triggering the code and the flashing arrow. Maybe I searched wrong, but I didn't see this mentioned anywhere on volvoforums or matthews.

To fix, you slide the plastic, polka dotted piece in front of the shifter. Squeeze the two clasps on the plastic piece under and slide off. Next, unclasp the plastic piece that holds the shifter. Use some contact cleaner, some canned air and clean around the button. Make sure the car is off. Take the W piece off, by unplugging it from its green electrical connection socket, and clean with clean towel. Put everything back together and make sure the W button goes up and down with ease.

That was it. Again, if you have no obvious tranny problems, look for this sticky W button. If I have time, I'll post pics.

 

Hello, I have this issue also, the W button is stuck. I do not see any polka dotted piece. I have a V40. Could you post a picture or two?

Thanks,

Dave

 

He is writing about the rubber pad under the radio. It's got the little bumps (polka dots) molded onto the surface of the rubber. It just lifts out. Under that is a hard plastic piece with two clasps on the sides that you squeeze and lift out. I use a small screw driver to lever this piece up enough to get a hold on it.

 

Ah, OK. I got it. I cleaned the button and it now works fine. I cleared the code but it came right back. Any ideas?

Thanks.
