Question about Volvo S40
It happened suddenly, when I was stuck in traffic and when tried start it suddenly wasn't as powerful as 1 min before. never had any problems with the car it never stopped on the road but it has now 160000 miles on the clock. Thank you for help
Some of the newer Volvo S40 cars also have electronic Accelerator pedals which affect a lot of the system when they wear down.

Run fault codes and look for torque converter clutch solenoid/servo problems and TCM problem. Check oil condition and change if tan coloured.

I'm assuming that that smoke was more previlant while going uphill because that's when the turbo would be really spolling up to max psi. I would guess that if you really got on the gas hard and got the turbo going even on a flat surface, that you would notice the smoke too. The loss of power and the white/grey smoke are tell tale signs that your turbo is bad or starting to fail. Good luck!

iv only st come on here and seen this post i know exactly what this problem is. it's the waste gate in the turbo gets full of carbon and then over boosts itself and put on the engine management light and when you turn the key on and off it resets it. so what you have to do id take the turbo off and clean out the waste gate which is on the exhaust side and that will get rid of all your problems and the better you clean it out the longer it will last.
