Sneyolg 30 Posted October 6, 2015 Posted October 6, 2015 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. Quote
paul.h Posted October 6, 2015 Posted October 6, 2015 Welcome to the forum. You will need to have a diagnostic check to see what the cause is, anything else would be a list of guesses and then you could replace many parts before getting to the faulty one. Normal servicing items to check though are when the fuel filter was last replaced and if the air filter needs replacing. Quote
Sneyolg 30 Posted October 11, 2015 Author Posted October 11, 2015 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 Quote
paul.h Posted October 11, 2015 Posted October 11, 2015 You could have a look at the pipe and see if it has softened. Also get somebody to rev the engine and see if it does collapse whilst you watch it. Quote
