Volvo Common Problems

[Peter]

850 & S70/V70 -2000 :

– ABS/TRACS module stops working (cold solder problem)- This one is an easy fix, you need to remove the module and find someone who will solder the circuit again
– Heater unit – maybe it’s not very common, but happens more usual than in other cars.
– odometer – plastic gear inside the odometer breaks when near ~267.000km

S60, S80, V70 2000-2007

-Throttle body failure
-Stop Light relay – when it breaks only the 3rd stop light on the window works
-Automatic Transmission – often they wear out becouse of the ‘sealed for life’ policy, remeber : ALWAYS CHANGE YOUR TRASMISSION FLUID IN A VOLVO or SAAB…also there was a problem with the software

Schrodingers Box has a YouTube channel where the throttle was a problem on a Volvo. And yes, if it’s sealed from service…I must defeat it! Those engineers made a car I bought very young into my automotive days take 17 hours to change the transmission fluid. It broke every pump I tried to put the fluid into that “nonservicable” transmission because of back pressure.

No matter how little I pumped and the relieved the air, I couldn’t tell if I made progress as air pressure dumped fluid back out. 🙁

If I were to do it over, I might drop the transmission, turn it upside down and poor fluid into it’s easy exit bolt. Once it was right side up again and installed, I could take out it’s screw on the side which is the “fill line” and let it drip until it was correctly filled. (3 quarts for a 2 quart manual transmission and 17 hours of milking a tiny O2 plastic tube meant to deliver air into a humans nose I had success. The whole was that small! :whistle: )

addition to your s60 line: main cause is not just transmission fluid, i found that transmission cooler inside radiator would fail and then, coolant would mixed into transmission fluid and then, blow apart clutch pack and such…once you get transmission pan off, bottom will be full of metal.

overall, they are good vehicles..
