Hello there!
I have a V70 2001 model. It has worked like a dream until a few days ago..The engine runs as normal when cold - as soon as it reaches normal temperatur the engine just lose power and the rpm varies between 1000 and 3500. (It runs on 2 or 3 cylinders). When the engine cool down it starts and runs as normal again. I had it in a garage (in France) and all they managed was to give me a readout from the diag unit. The code is 8b44 344. Anyone who has an idea?
regards

 

Is that a Generic code or a Volvo code it looks weird?

 

hi
well, I really dont know - I suspect that thefrench technicianjust gave me some numbers..! I will try to get another tech to look at it next week. I started the car today and the problem is still there. the odd thing is that when I stop the engine for about 10 minutes after it stalls, it work just fine the rest of the day! thanks n regards

 

Yes please see if there is different codes.
