Hey guyz any body changed there MAF sensor and may b can tell me the part number and the price?
And is it the same with S4 MAF may b?

RS4 MAF is different to S4, it is a lot larger tube. I suspect the 'guts' of the sensor are the same. Anyway the part number is 077 133 471K which is £250+, BUT if you add an X to the end of the part number it gives you an exchange item and this is only £75+Vat!!! Baragin.

HTH

Thanks man 4 the info,
but can u plz explaine 4 me whats an Exchange item? its sounds like Audi thing.
I am sorry to ask you this, but r 100% sure about the number cause it takes at least 2 weeks 2 order an item from the Stupid dealer here. So u can imagine what would happen if it comes as a wrong part.
Sorry agine and many thanks mate

Hi,

Just order 077 133 471KX from your dealer, and once you get the new one, give them your old MAF. This is what an exchange is.

Also means that the item has been reconditioned usually, although, while talking to somebody at Milton Keynes, it also could mean that a new sensor has been fitted to the old body, or that it is a completely new unit..........clear as mud then...

Usually for MAFs it's brand new units, maybe old housings but the sensors are brand new They can't be fixed, BTTriedThat and it doesn't work....

Thanks boyz, appreciate your help.
Wow Mihnea, always surprising knowledge.
R the EGTs the same or am just pushing my luck?
cheers 2 all.

If your MAF is shot, your EGTs are going to be much higher than with a normal MAF. If you have doubts about your MAF (poor performance), just disconnect it and run the car with the MAF unplugged. You should notice an immediate boost in performance, otherwise it means the problem is not your MAF...

HTH,

Mihnea

With it unplugged you will also get worse MPG. But performance will be back as it should be.

Excellent boys.
Although I have never taken a close look at it, I will try to unplug it.
Thanks allot 4 your help.
Will keep u posted.

Did it last night, unplugged it and went for a drive, the boost kicked back and the car didn’t go to limp mode.I have to say the car was behaving strangely when not moving like the Revs will go up and down, I guess that’s due to the unplugged MAF.
So went today to the dealer and ordered the exchange MAF sensor and cost me 120$US. They said it will take 2 to 3 weeks.
Hopefully this will solve the problem.
Thank u all for your help and support.
Special thanks 4 Stuner for his help here and in the PM.
Cheers to all.

MAF replaced, my baby is back.
I think it all started when the K&N filter was installed and the oil from the filter damaged the MAF, so be careful guys when u go K&N.
Funny the dealer told me that what I ordered and replaced is not MAF its Air flow meter, what do u guys think?
Just wanted 2 thank u all 4 your help.

same thing. MAF = Mass Air Flow - referred to in techogeek as Air flow meter.

glad its working again

thanks sitas3
That’s exactly what I said 2 him, I said it must be different names for the same thing then he said NO NO like he knows everything he even asked which one am interested in replacing so said to him just change the part I ordered

Are MAF sensors cleaned/replaced at service? Can they be done DIY? And are there any signs to look out for if they are dirty/buggered?

Thanks

Bob
