2008 Trafic Warning Lights - Help

Post by Malcolm »

Three lights have come on without noticeabley affecting starting or performance. My initial thoughts were heater plugs.
1) Preheat/electronic incident and water in fuel warning light
2)Warning light for monitoring exhaust gas
3)SERV

Connecting a cheap diagnostic tool, code P0100 - 'Mass or Volume Air flow Circuit Malfunction' was shown.

I understand that the SERV light will be resulting from the other two lights. The heater plugs haven't been changed in the five years I've had the van, initials thoughts were that would be the issue. Water in fuel? Service done in the last few thousand miles and filter replaced, so wouldn't have thought that the issue.
The exhaust gas monitor. Do these engines have something similar to a Lambda?
Does the code P0100 give a clue to issue with Air Flow (MAF) or is it a result of the previous issues.

Headache, any help greatly appreciated.
Thanks

FYI. Got another MAF yesterday and surprisingly after an OBD reset all lights are now out. Hadn't really appreciated rough running but is better after a cold start
