I'm running a 200Tdi 110. It has about 142K miles on the clock. When i got it it accelerate well and you could feel the turbo coming in.
Now it just doesn't accelerate. I'm having to drop down a gear on hills and you don't feel the turbo come in. The overall power is not down it just lacks acceleration.
I've changed all the pipework, the fuel filter, the air filter and the intercooler is also clear. Anyone any ideas on what the problem could be? (is it the turbo?). The drop off in power coincided with fitting a raised aire intake but I don't think the two are connected.
Thanks for any help.
Cheers,
Guy
