Recently got myself a second hand 159 diesel. One owner, 99k miles, excellent condition. ANYWAY...
A few hundred miles after buying it, I noticed slight hesitation in lower gears with a sound, I can only describe as the car is panting... After another good few hundred miles the hesitation becomes more noticeable. The turbo also whistles, a bit like a police car.
Now..I take it to the garage, explain my problem, they do diagnostics which show DPF error - so they do an engine deep clean. DPF was 98% saturated, and is now at 70...£248 later
and the problem is still there. It did run a little better for about 10 minutes. I thought maybe I'll thrash it a bit. Nope. Limp mode. Towed back to the garage. Diagnostics. AH yeah its the EGR valve. Ok but I cleaned that recently. Yes but it's showing an EGR error...£177 please
. Problem is still there. Garage calls me "Its not the EGR valve, its actually the turbo" That's when I took my car back, I can't keep chucking money at various things to see if they get fixed. Had a hesitational drive home. Cleaned up the MAP sensor and now I'm writing this.
Any ideas? Also, phoned up the guy who sold me the car, he gave me £300.
