Where can I get IPA?

Cheers Pete, looking foward to seeing your RS2!

Hi guys...

long time no see

quick question regarding cleaning the MAF...

after cleaning, what is the procedure to reset the MAF sensor?

what i did was, turn engine on and idle,

unplug sensor,

turn engine off,

plug sensor back in.


my worry is, is it the other way round? like, unplug sensor, then turn engine on?

thanx in advance

[Ski]

anyone?

Hi Matey, you can get it from Maplins online (just put IPA in the search box) or check for your nearest store. Sorry don't know the sequence though!

Erm confused, what are you referring to reseting the sensor???

MAF readings would go directly to the ECU IMO, S2Central should be able to answer this though.

yeah even if the maf is dirty, reseting the sensor will clear the over boost protection for a few miles...

also, if u clean ur maf crystal clean, it the over boost protection will still kick in unless u reset ur sensor...

it seemes to have sorted itself now, cleaned it and ungplugged the maf while it was running, switched engine off and plugged it back in.. all sorted

o.k can anybody clear this one up? because i'm under the impression the MAF is the sensor!

yes the MAF is the circular tube that connects the air filter to the pipe leading to the intercooler and it measures the amount of air.. so its a sensor.. and it gets cleaned with IPA. like all sensors it can be reset (i think).

when i say reset ur sensor, i mean unplug ur maf and plug it back in.

@Ski. I think you're on the wrong track here. Cleaning the MAF is not going to cure an overboost protection fault. Fixing a boost leak will cure that.
Overboost Protection can be cured temporarily by switching the car off for a few seconds and then restarting. Admittedly, removing the MAF to clean it and then refitting it may help as you are reconnecting hoses and clips. But its not the cleaning that fixes the fault.

I've never heard of a way to reset the MAF, as all it is doing is measuring air flow. It doesn't store any values. It passes its readings straight to the ECU. The ECU then adjusts the mixture accordingly. If the MAF is dirty it will give incorrect airflow readings and so the ECU will tell it to use the wrong amount of fuel. Cleaning the MAF should fix this.

Feel free to correct me on any of this. I'm heading out in to deep water here and I'm only just managing to keep my head above water.

I'm not going mad then!

hmm.. weired.. has cured my problem a few times now in the last few years :/

plus i read the trick on this forum a few months back how to reset it doing the unplug trick i mentioned and that helps too..

either way, after celaning the maf, my overboost protection has stopped, car pulls smoother, less fuel and faster

plus the maf was secure/tight in the first place...

weired.
