Audi a6 c5 2.5 TDI Quattro avant 1999
Sorry for my english, i'm not native english..



Hello, I own an Audi a6 C5 4B 2.5 TDI 150HP diesel Quattro avant 1999 V6 Manual (EU).


I would like to add performance parts (turbo, transmission, suspension ect ..) She starts to get old and we start to feel it
How could I find references? Or owners of the same model or smiliaire could perhaps refer me?

I am looking for a cable to make modifications on the calculator to change the turbo, to encode new keys and especially to encode my new ABS unit




Thanks you.

For coding abs and a bunch more buy vcds cable, unfortunately the Ecu on your car is not possible to flash trough the obd port as the chip is one time write only ! You will need someone to solder sockets and fit new chips on the Ecu motherboard. For more power the later 180 Bhp injectors are a mild upgrade along with the later vnt gen 2 turbochargers gt2052v.

Thank you for answering.

Do you have a reference for the cable or a link?

If I understood correctly, I can use the turbo & injectors of the 180hp version of the same model?

I forgot to specify that the ECU has been tune up, and that the immobilizer is off

Imobilizer it’s easy to bypass on the immo2 Ecu…yep, for a mild upgrade the gt2052v from the later 2001 on sport models are good to go and a bolt on mild upgrade!
