Further to my messages to you recently re Service light
Indicator on my dash board. I have a Citroen Picasso C3 1.6 VTR 2011.
This light keeps coming on and off on my dash board. Yesterday it was off all day. But now it's back on to day.
I got a dinogstic test done on my car this mornning and the fault came up as . Intermittent Air Flow. But no code.
As I said I had my service done recently and all was ok. Changed filters oil and Air filter. And was reset
Can you be of any more help please.
Regards
Roy

Re: Service light on Dashboard
Possibly there is a fault with the MAF (mass air flow) sensor or its wiring/connector. It could have been disturbed when the air filter was replaced. You could also check for an air leak between it and the engine. The MAF will be between the air filter and engine. On the parts diagram on this link it will be part no.10 https://www.ebay.co.uk/itm/275911546960 ... gIGfPD_BwE

I've deleted your other thread - please don't create multiple topics for the same issue as it duplicates answers. Please just update this thread in relation to this issue.
Regarding the Fault code you specified, see descriptors below. Although there is a long list of suspects, I would certainly check the Mass Air Flow Meter first and clean it with some specialist MAF cleaner first (Very carefully as the sensor wire is highly sensitive) and check all connections before moving on.
