is this the MAF? if so, how can it be cleaned?

Yup - use isopropyl alcohol to clean it, at least 91% alcohol IIRC
 

make sure to let it dry out, maybe over night - it should remove any residue that may be on the wire. Be careful when cleaning it - I would assume you could dip the sensor in the alcohol, maybe very gently move it around to work anything off of it - then let it dry...

Hey are you coming down for Avantfest?

when is that?

k. I'll try that. ps: what happens if the car is driven without the MAF?
 

we'd like to figure out if this is the cause
of the
"17965 - Charge Pressure Control: Positive Deviation"
DTC...
already checked the N75 Valve, looks fine.
switched divertor valves and vac lines to the
divertor valves 3 times...
checked all hoses and tbb for leaks/tears...
couldn't find any probs with the above,
yet the car still goes into limp... .4 bar max boost
cleared the code a million times already...
still comes right back after going WOT in
any high ratio gear at low rpm's

thinking if driving without the MAF in place
doesn't bring it up, then it's def the MAF,
and it'll be a sigh of relief knowing what
caused the problem.

Saturday 10am@Longwood gardens. Daphne is running it again.

ugh. can't... already made plans for sat that I can't cancel.

That's cool. Maybe I'll see you again at the next meet. You talked to Jackie lately? Haven't seen
 

her on in awhile.

nope.
 

got no idea what she's up to. she pops
up on aim every now and then.

yo, can you post a pic of an N75 valve in the S4 engine bay? TIA
