Battery with poor charge often gives random errors too! Worth a quick check

The fuel and the vdc stuff really sounds like my problem I had once..

But maybe disconnect the lead into the MAF and clean the connectors..

Check battery voltage when engine is running should be between 13.2 volts and 14.8 volts
If not it is not being charged.

Alfa 159 Codes

Hi, I'm looking around at the moment for some answers to some codes I have on my low mileage 2.2JTS 159 and found your post. Everything you mentioned is exactly the same as what has happened to mine, including the low/no fuel (and warning light). Can you tell me please, did you ever get to the bottom of what the actual source of the problem was? It sounds very much like one item tripping everything else up in line by the sounds of things. Any help you might be able to offer would be very much appreciated.

Regards
RCV
