He everyone.
This forum is awesome, full of useful knowledge .

This is my first post. I'm work with car electronics for 5 years.
I'm trying to do Cat off and disconnect rear lambdas (Custom downpipe).
Car is Audi 3.0 V6 ASN with A/T.

So far I found and change these parameters.

Please check this, maybe I'm wrong.

22010 01 -> 00 cdkat
22012 01 -> 00 cdlash
2200c 01 -> 00 cdhsh heater diag
2200d 01 -> 00 cdhshe
22582 01 -> 00 cwdlsahk
22029 0x33 -> 0x11 CWKOLNS
18E29 03 -> 00 err. class P1118
18E28 03 -> 00 err. class P1118
18E2A 03 -> 00 p1122
18E2B 03 -> 00 p1122

Error code class table
18DE3 -> 18FF6

P-codes table
190A8

Driving fine and has no fault codes after that but...

I can't find CLRHK (or CLRSHK - car has wideband lambda) so I don't sure that post cat correction is off. How Can I check this with VCDS?

Readiness show failure in Oxygen Sensors and Catalitic Converter, is that normal?

In Meas. block 046 shows always "Test OFF" for Cat.
Block 043 and 044 (sensor agning) - B1S2 OK, B2S2 OK

I'll be glad for any help or hint.

Once again, great forum, good Job!
