Hi,

Could you please tell if you know some reliability problems on the MAF Sensor Audi RS4 B7 ?
I have some light timing retardation sometimes and MRC suggests me to change it ?

Ref Audi OEM : 077133471M
Ref Bosh : 0280218187

The part seems difficult to buy out of the official Audi Network.

Thanks for your feedback.

they can be quite temperamental, mine was intermittently playing up apparently - i changed mine about 18mths ago, luckily it is a 5min job you can do yourself

Changed mine as well a few weeks back as preventative maintenance. Can't hurt after all those years.

I have a spare unused/unopened OEM MAF in Belgium as I ended up buying two due to circumstances. Don't mind selling it 20 percent below dealer price just FYI.

Thanks for your offer but I need it for thursday as I'm leaving on holiday with the car.
So will place an order to my Audi dealer ...

Thanks !

First step, take it out and clean with proper MAF cleaner.

I used to have searching revs at idle. Sorted after a good soaking.

MAF cleaner. Tell me more ?

I had the same until I was on my way to the AMD rolling road day when it went kaput and became almost in drivable. A new one foxed the problem and stopped the hunting revs.

This is the stuff I've used and was recommended to me..
