How do i reset the radio code in a volvo 850 glt sedan 1996

go to your local volvo dealership, and you must have the car in your name, but ask one of the mechanics if you can have the code for your radio, they'll look it up and give it to you I believe.

One BIG question I have for do you know that the mileage is not way over what you've been told?...

small tip for the future.......if you ever look at another car for anybody, and the speedometer doesn't work...pass up the car..there is always another one down the road waiting for you.

Hopefully this will help you, and thanks for letting us at help out...happy New Year

1996 Volvo Oil Issue

Change the oil and filter.  I had this same thing happen; the sludge reminded me of chocolate mousse...  The mechanic who takes care of my car pointed out it had been a while since my last oil filter change.  Over time the filter gets clogged, and the engine basically whips up it's own oil - a la mousse.  A more expensive possibility is that the PCV valve is clogged and needs to be changed.  Again, in this instance the engine can't breathe properly, so it not only whips the oil up, but starts to shoot it out the dipstick hole, sort of like when you have to breath through your mouth when your nose gets clogged up because of a cold.  Didn't seem to injure the car, or freak out the mechanic.  Best of luck.

Obd system diagnostic trouble code rejection

IPD, the indy authority on all things Volvo says this is an actual emmission control device. Especially during cold starts/winter. Have this system thoroughly checked at a Volvo dealer or Indy Volvo shop. Could be pump, valve, hoses, etc. But make them show you the faulty part and explain to you how they diagnosed it. This will help you know you are not being ripped. PLus they should take it for test drive(s) to make sure P0410 does not reset.
