Hello all,
It has been close to a year now since I started this thread. All that time I've been driving around with a subtly crippled engine. I got rather used to it, but as temperatures increased over the last few months, the intensity of the phenomenon started increasing.
Two weeks ago I bumped into
www.volvo-forum.nl, the Dutch counterpart of this site. Browsing around the threads waiting for my account there to be activated, I came across a few other people who were having this problem. And a potential solution was listed as well!
I tried the mentioned solution as well, and it works for me too. Some 200 km later I still don't feel the fluctuating torque anymore, so things are really looking good.
Of course I'll share the thing that worked for me with you. I cannot guarantee that it works, and be carefull, as the brake cleaner produces very dangerous gases when heated.
The solution to my problem was to clean the turbo pressure sensor. This sensor is very easily reachable, sitting on top of the inlet manifold, just below the insulation on top of the motor. You have to unscrew one Torx screw, and you can gently pull the sensor out. I then sprayed brake cleaner on the sensor, also into the sensor tube. Getting the liquid back out took some patience (and violent swinging it around), but I did see some very small particles coming out with it. I put the sensor back, and started the engine. No fault codes, engine running smoothely. And as I told already, no more torque fluctuations when I was driving on the highway the day after!
Hope this helps some people on this site as well!
