Renault Trafic Maf Intermittent Issues

Post by Adamhratcliffe »

Hello.

I am having yet more issues with my Trafic. I believe it to be MAF related but equally after hou8rs of reading other posts it could be more.

The van only seems to start when the glow plug light and EML lights are illuminated. (MAF Fault). When they aren't illuminated it starts and stalls immediately. I have tried a new Continental MAF which gives the same issue. When I read the codes in this state I get a MAF related code. As far as I understand the van should start with the MAF plugged in or not. When it does start (lights illuminated) it runs absolutely fine with boost etc.

I wondered where do I next go.
Should I try a Siemens MAF or are the Continental ones the same?
Is there a way to reset the system so I can get the error code to show up and get the van to fire. Without waiting several days when it sometimes comes back on.
I have read somewhere that this may be happening because a temp sensor/Crank sensor is having a meltdown so is totally preventing the van from running.
Thanks very much.
