Audi A4 power loss

yes sorry was thinking of MAP rather than MAF. Yes leave unplugged whilst driving

long jon : is this the same as what others are talking about when they mention MAF ??
when you say unplug , do you mean leave it unplugged as I drive or unplug and then refit before driving off ??

no disrespect to anyone but i think you barking up the wrong tree....
if it only occurs when wet or damp then i bet its to white multiplug for the throttle pedal thats corroded...

you will find this if you take ya wiper arms off
take off scuttle trim at bottom of windscreen
drivers side you will see eng ecu
take out but leave wires connected
then look down to see a few multiplugs
disconnect white plug and i bet you'll see green corroded connectors
clean up if poss and i bet it you'll have it fixed.
