I bought this thinking it would work with my 2001.5 audi s4. Needless to say it didn't work and the guy wont let me return it so make sure that your car is A box compatible and has a Bosch MAF. $425 obo.

 

bump just make me a decent offer and you can have it.

 

Hey. i'm a little confused with the whole A box Ch box. What does this mean. I've been wanting a new ecu for my A4 but i don't know where to start. My audi is a 2001 A4 1.8t.. if you could let me know and everything is correct maybe we can make a deal?

 

This ECU is only for a 2000 S4 6 speed with a bosch MAF

 

Just got an s4, but mine is a 2002, how do you determine which box you need?

 

If you need to know what ecu you have you can either pull it out and look to be sure but most likely this chart will work http://s4wiki.com/wiki/Generations the only reason why your car wouldn't match the list is if you have a different MAF then the list says. For example a 2000 S4 that was converted from Bosch MAF to Hitachi is not going to use the same ECU as one that still has a Bosch.
