passat/audi 1.8T MAF
« on: 10 October 2011, 14:46 »
will a 1.8t passat/audi MAF fit a mk4 AUM? I dont have any part numbers or anything I cant find anything printed on it, but would it be a direct replacement for my aum maf?
Just wondering as my current maf is playing up so wanted to try this one, I bought it off ebay around a year ago and never fitted it as I thought it was the wrong one but just opened it up for the first time and it looks the same

cheers
20vt conversion, sig pic coming soon!

suppose it would depend on what ecu the passat/A4 was running. if its a DBW then it would most likely be the same part. if it was a cable throttle like the agu then chances are its not going to work on your aum.
without part numbers or knowing what engine it came from its hard to tell..

Try it and see, if its compatible it will work, if not, w4nky idle and running.

Make sure same diameter though..

How will I know if its running properly? might sound like a stupid question but I dont know if my engine has ever been running properly since I got it. If its running properly will it run the same as if the maf is unplugged all together?

Unplug the maf and see if it runs better, if so your maf is playing up.

yeah cheers I'm gonna try that later, but when its unplugged is that what you would call running normally? so if I plug in the passat maf it will run the same as if its unplugged (if its the right one)?

it wont fit mate, the housings are different, you might get away with changing the sensor over instead, but you need torx/secuirty screws for it

Yeah I found this out yesterday, can't just change the sensor either as the plugs are different. No probs though as it turns out my maf is fine, it was a lambda problem thats now fixed  :smiley:
