Could be either or none. Swap them (MAF) left to right and see if the code stays or goes to the other one (G70 I believe).

Do you have a mechanic or doing it yourself? Either way, take the MAF's off the carbon intake to make your life easier and run it that way.

Yea, I believe the G70 is the left and the G246 is the right MAF sensor.

its at a work shop has been there for 2 weeks now, i dont really have a good feeling about them...i asked them to swap over the MAF's and see if the code followed....i got this response


Unfortunately late last night’s and mid-morning diagnosticsnetted not good news. We still have a few faults being reported even thoughdevices have either been changed, swapped or disconnected. So John, no MAFsrequired from Audi at this stage.

We have an auto electrician working on the car right nowtesting the wiring harness and ECU, so I will have a more detailed answer in anhour or so time…..

(me here) the car ran fine has done so for the past 8 years, have not had 1 fault code other than headlight self level (which was after we painted the car..headlights came out!..the car was perfect prior to my cat delete and Apr ecu upgrade?? i dorove it back to the work shop after having it home 1 day as iut ran like a bag of s,,t ..i took the airbox off the passenger maf connector was broken inside, i unplugged both MAfs drove it to the work shop and it was fine then too.idled nice etc...any suggestions..could the issue be in the software update from APR?? or have the fried the ECU somehow....open to thoughts

thanks johnny

Bad MAF wiring from what I can tell....and the shop should have had that for an hour or twos worth of work.

perhaps when the put the new plugs on? anyhow at this point 6hrs labor at $110 and hr and counting....i want to take the car but dont know who else to give it too, being so rare here no one seems to know them well..

[905084]

Not plugs at all. Do you have a code checker? and basic mechanical ability? I hate to see people pay someone else to learn an RS. $660 and they have no clue?

sorry not spark plugs they wired in new MAF connectors as they broke the passenger side MAf connector (they were $10 bucks from audi) the plastic connector that the pins go into.

i have a friend that always tuned my evo , the build race cars he has no specific Audi diagnostic tool though, but he said he would help me with it.(they have a maineline dyno etc).i have mech ability of a potato ..i can change Maf's air filters oil, but not wiring , thanks mate

[905084]

Have your friend that tuned your Evo help. I would guess he has good diagnostic ability. Logical thinking is not restricted to knowing the RS, you just have to learn the car a bit and the logic will flow. G70 is the right MAF, I believe and G246 is the left (as you are sitting in the car). Dear god I don't want to confuse passenger and driver sides as I think many/most of these live on the left side of the road Get cable from eBay for $1 and download VCDS Lite and it will help immensely.

[johnnie27]

ok so sitting in the car it was the LHS maf that had the broken (connector) i think i will just go get her, worst case i can drive to my mates workshop with maf's unplugged again! thanks my friend

[905084]

That is G246. 4 wires to the MAF, the signal is shielded and if it is shorted that could be it. Still recommend swapping left to right MAF's to make sure it is the wiring and not the MAF. Good luck!

[johnnie27]

work shop just called !!! siad yes it was a worn end of the LOOM you know where it bends back on itselft to sort of clear the airbox, they have repaired the wiring , test drove the car..he said its ballistic (and he has a s/c S5 ) so thats good news, no extra $ charge too..he is going to test the car when it cools down again to make sure no more codes..so i am somewhat relieved

fingers crossed my phone doesn't ring in the next 2 hrs....thanks so much for all the advice too!! johnny

Sounds to me like they likely wired in the new connector wrong and just cought it now. It's easy to make the mistake when replacing a connector.

car is going epic and beautiful and stonking hard!!, broken corrector fixed and small repair made to loom on passenger MAF (at that silly bendy spot) a wire had frey'd)

Sweet as mate, I hear ya, glad it got sorted!
