VW Golf MAF question and help needed

[Jmac]

I would guess its either the temp sensor or it could be running too cold ie Thermostat. I had an A4 do the same and it affected the running and furl consumption. That thing has never ran better.
Like H100w says you need some figures from your ecu to see what its getting and what its giving.

Last mechanic replaced the coolant temp sensor which did bugger all, except set me back $210 before i got on these forums and members rightly suggested the MAF but seems like there is still something else going on.

Just no faith in these midas guys as they scanned it and first time it showed 7 separate issues then apparently none. Will take the Bug-Racer suggestion on board.

Thanls again for replies

Ps: anyone know the guy that works at North Rocks, big beard and long hair. Works on aircooled mostly ...used to take my Bay bus there and he was pretty good. Think his name is Andrew. Wonder whether he has know how for a modern VW.

Yeah Midas Hmmmmm mate 7 faults generally only means 1. Like i say you need to see what inputs and outputs you are getting within measured value blocks on VAG 5052 or Vagcom. You could have unmetered air (airleak) which too can cause dramas. In measured value blocks you can also measure what the O2 sensors are doing, this plays a very important role with mixture control.
Let us know how you go mate
Cheers
