check.......... ask pass by PM
Hi,
I need some help.
Car: Audi A4 2002 3.0 V6 8E0909559L ME7.1.1 with automatic gearbox.
The main problem: Less power than other A4 3.0 V6 220hp.
I want to delete rear O2 sensor. I found selection at adress:22006. Is it correct?
Please give some hint or if anyone could make a simple mod with deleted rear lambda and a little more power. Car is too slow for the genuine 220hp.
Usa version could be reason?
I checked sensors (temp, barometric and others..), checked fuel pressure, checked compression/stroke, maf sensor...everything fine. Has got new spark plugs... Filters.
Please help.

Please explain what you want? The entire rear o2 removed? Or just catalyst monitoring? Do you have specific fault codes?
22010 is CDKAT, catalyst diagnosis.
22583 is CWDLSAHK, for sensor aging.
(0 CDKAT and CWDLSAHK if you want to gut the cats)
2201E is CDSLS
22027 is CWKONABG
(0 both if you want to remove secondary air injection)
Should also disable post cat lambda control via CLRHK if you're going catless to prevent wacky trimming.
24339, increment it by 1 (set bit 0).
for low power.........are you test the distribution? cilinder compresion?

Sorry for late, I had problems with dk website load. Thank you for descriptions.
There are no fault codes, just less power than the other the same audi..
Customer had faults from secondary lambda probe about one year ago and bought new cats and lambdas.
Then faults disappeared but still no power increase. Dyno shows 180hp.
Engine checked, distribution, compression...

The AWD audi's are subject to a 20-25 percent drivetrain loss. 180hp sounds right.
