Volvo v70 code po340 - 2003 Volvo V70

SOURCE: PLEASE HELP volvo 1998 v70 radio code

You need to call a Volvo dealer. They'll likely ask you for a number on a sticker on the radio itself. You can find that sticker by pulling the radio out (push the 2 skinny vertical "bars" on each side of the radio to pop them out, then pull on them to pull out the entire radio unit).

Hi:
The only way to get the radio code is at a dealer, and often you have to have the serial number of the radio, the VIN number of the car, and go to the service department. This is an anti theft preventative, and keeps theives from reselling stolen radios. If you have been to a Volvo dealer and done all I suggested above, then your only option is an aftermarket radio .

If it's not the fuse, the connections may be worn out inside the wheel.

The exact same set of codes have just come up on my car, the same car and year. Did you solve it? I am thinking cleaning the throttle body first, any help appreciated....
