Hi Thanks again will try that. Sorry for delay in response been away from home

Hi, Thanks for your reply. The van has only just been serviced when all filters were replaced. Someone has told me that it could be that given the age/milege that the van has done the cause could be a weakening intercooler pipe that is compressing when the engine/turbo comes under load restricting airflow to the turbo then reganning full shape when load taken off. Does this make sense? Regards

Can anyone help please. The engine management warning light on my van comes on when the engine is under load ( going uphill with full throttle ) with slight loss of engine power. The light goes out immediately I lift of the throttle and the power comes back. The light does not come on at any other time. Any ideas what can cause this please.
