Very true. But bad mafs can cause the ECU to log lambda sensor errors. And he said he had that error as well as the misfiring.bilko1 wrote: MAF sensors rarely show up as a fault code you need to log the data from them.

Re: RS6 MISFIRING ANY IDEA'S OFF CAUSE'S???????????
i got it checked today all the vacuum pipe's seem ok im gettin it compression test done on monday to check the pistons are all ok i personally dont think there's nothing wrong with engine the exhaust misfires like mad just at 2000rm how do i check if the maf senors are ok?

I did read on one post in the past that water leaking into passenger side footwell from blocked roof drain pipes might effect the ECU electronics causing all sorts of weird responses, misfires etc.

Re: RS6 MISFIRING ANY IDEA'S OFF CAUSE'S???????????
Have you had any work done on it that involved taking the airbox off? Mine drove like crap and had really poor throttle response, was also throwing up lambda codes after I picked it up from the garage.
Checked the maf readings and both were sub 2 so whipped the airbox off swapped the maf's for good measure and fitted box properly. Now running smoothly and maf readings spot on.
Easy job so may be worth a try?

Re: RS6 MISFIRING ANY IDEA'S OFF CAUSE'S???????????
yes they had the air flow box off while driving it still doin the same misfiring it seem's so strange because ive taken it to so many people they still dont know wats wrong with it ive changed few things wat the garage assumed when it was throwin up the codes im just gona wait till tmrw when i do a compression test and see how it goes

where are you mate? I have asked this 2 times now. If you are in the uk take it to either unit 20 (grizz) or mrc

I checked my compressions a couple of months ago while changing the spark plugs they were all 160 psi, just so you know what to expect.RS6_2011 wrote:yes they had the air flow box off while driving it still doin the same misfiring it seem's so strange because ive taken it to so many people they still dont know wats wrong with it ive changed few things wat the garage assumed when it was throwin up the codes im just gona wait till tmrw when i do a compression test and see how it goes

Re: RS6 MISFIRING ANY IDEA'S OFF CAUSE'S???????????
Can't engine Mounts cause the engine to misfire ?
Sure I read that on here somewhere.
They should throw codes though.

They can cause codes, though, but no power loss or adverse effects. I remember someone doing the experiment. There was a rumour that faulty engine mounts caused the ECU to back the turbos off, but this was proven to be false with vagcom logs.
Common causes of misfiring could be:
Plugs (wrong part, worn or not correctly torqued)
Bad fuel (you're not running on 95 are you?)
MAF
Lambda
Air leak
Am I missing any?
