1.6 hdi 2012 c4 g picasso, as soon as my revs hit 2000 rpm my Interior fans all come on and I'm loosing power, I've changed the maf and map sensor and the battery. Has anybody seen anything like this before?? I cannot pin down the issue, any advice grately appreciated

It sounds like your BSI is malfunctioning and drawing too much power try doing a bsi reset.

It's a waste of time and money swapping parts out without diagnosing the issue first of all.

I suggest you get it properly diagnosed and then provide us with the full fault codes and the VIN.

Po100 maf sensor is the code I got and continue To get even tho it's been changed

Its related to it's circuit so could possibly be the wiring to the MAF or the ECU could be having issues. if you have changed it could be the new one is no good aswell, you need to determine what the cause is. Did you buy a genuine maf or a cheap eBay knock off. Most of the time they don't work right (personal experience). I think Siemens is the original manufacturer on your car but I could be mistaken.

Maf sensor came From a motor factor and was £150 I avoided ebay!! I did wonder if I should try returning it for a replacement. I believe the make I brought is beckermans.

I would get it tested I've never heard of that brand I wouldn't trust it to be honest. I would consider bringing it back and just buy a genuine one.
