Yes, it does come from the MAF, 100%. By the way, mélange trop pauvre is "mixture too lean" in english ;) HTH, Mihnea Thanks, i hope you're 100% right :wink: Another thing is that when i do a reset on the ECU. before it falls to 7psi, i find back a boost pressure, but never more than 14psi instead ...

Can it come from the MAF sensor?


What else could it be coming from?


Please help !

I did order a MAF sensor BOSH to AUDI.
I hope this is coming from it.

The error fault is :

"mélange (air/petrol admixture) too poor"

I did change the dump valves and did erase faults, i had 14psi instead of 20 psi (as it has been remapped) and the system came into fault .

I 've got 0.5bas back

after checking, it was coming from one of the two dumpvalves. So i ordered 2 forge motosport ones today !

Bloody Hell! This is bizarre! The last time I was on I mentioned about this that some of you guys might have boost leaks and not know (this happened to me) I was reading 0.5 constant and didn't think anything of it until I had a re-map and it was still at 0.5. If it's lack of boost the first thing ...

I was surprised by the feeling of a lack of pressure on my new RS4, so i took the pressure with a gauge. Has somebody already been confronted to this kind of problem on S4 or RS4 biturbo? No doubt 3 issues : - CHECK ENGINE that put the system in safety control and reduce to 0.5bars (7.25psi) - Leak ...

Thanks all of you for your instructions. My garage will get the AWE gauge and i don't know what will come in the box. I will check for the localisation to take the boost pressure like you told me.

Thanks a lot

I bought a AWE boost gauge.

Where should i pick up the boost pressure to get it on the gauge?

Thanks
