I have an electronic fault occuring every time I go uphill with a complete lack of power, ie 15 mph but no black smoke. Going downhill, no problem. Car is otherwise great and gradually returns to full power. I have had all fuel pumps, and various sensors replaced over the last 5 years and EGR about 4k mls ago. I did clean EGR myself very recently and changed fuel filter plus have tried 'expensive' diesel and fuel additive. An excellent local independent diesel specialist could not find code but did otherwise confirm injector pressures etc were all OK. I have not taken car to local Renault dealer as I have no confidence they will find actual fault. Done 153,000 mls. Any ideas as to how I find fault? I did run very low on fuel once and hence changed filter in case debris sucked into lines but no difference. Thanks for any ideas.

I just love comments like the following:

"An excellent local independent diesel specialist could not find code"

Not that excellent are they, bet they still charged.

"I have not taken car to local Renault dealer as I have no confidence they will find actual fault."

Why not give it a shot, they might just be sucessful since they will have all the diagnostic kit.

Guess your alternative is to ask on a forum and hope a magical cure is available via a free download.

This is not meant to be condescending, but you are changing down to a suitable gear and raising the revs into the power band aren't you? Not trying to climb a hill in 5th at 30?

How does the engine behave if you put it under load on the flat?

Tried purging the fuel lines and filter to ensure no air locks?

Lack of power on a hill is a very common fault on vacuum operated torbo's. And most likely faults are (weak vacuum pump) vac line connecters Rubber elbows where there prone to splitting. This fault can be checked out using a vac pump or small vac gauge to try and visually check these out would be a waste of time At vehicle idling your vac pump or gauge reading should be approx 26/27 inhg. Get this checked out first and i think you'll find out this is your problem Hth Regards Mickeybo
