Hi,

I have a 2001 Model Vw 2.5 TDi T4 Callavell van.

this car has been great, However over the last 2 months It has had a great reduction in power.

What basicly happens is that the engin light would turn on, and there will be a great loss of power, but then suddenly the light, would go off and the power would come back. some times there is a loss of power and the light does not show. it started as a small loss but now it is deffinalty getting worse.

VW whant to strip the enitre motor as they dont actualy know what is worng.

any ideas would be a great help.

Thanks
