Hello dear community, there is really a lot to read because of the V50 2.0d regarding the power loss. Since I still have no solution for my problem, maybe one of you has a tip for me. The following problem: My V50 had less power than normal already when I bought it. This was pushed on one of the two brown turbocharge control valves. As it was obvious, this had several small cracks as if it had bursted. This ha of course I changed, which resulted in a “improvement”. Nevertheless, the car has no full power. It is impossible to overtake in 4 or 5. Even my 1.4 TDI is far faster. I was already at 2 Volvo workshops, both of which have confirmed that the performance is too little. Both have checked the hoses, all of which are firmly on it. I have not changed the other valve at the moment, since it still looks “good” without cracking or similar. If the turbocharger was defective, would there be an error message? And even more, would an improvement be possible with a defective turbocharger by changing the valve at all? What else I forgot: There is no error message in the display or anything else.
