Hi guys,
Just joined so hello to you all
I'm after some help with my friends 2005 55 plate 1.8 s40. He has had it since new and its been very reliable but in the last week it has developed a fault that has gone from intermittent to every time you drive.
Basically the car starts up and but the revs are high and if you push the accelerator the revs take drop a bit to slow. After about 50m of driving the car goes into a limp mode and the engine runs like its on 2 cylinders and you get a message reduced engine performance / limp mode. It's so bad it can't really be driven.
In the last few days I have replaced the throttle body and an O2 sensor but still get the same fault code
P2110 forced reduced rpm.
I have tested the whole engine side loom and all checks out, I am now thinking PCM /ECU.
Any advice that saves me having to take it Volvo would be amazing
Thanks
Chris
