I have a B7 A4. On the ross-tech website, it says there are some functions that can work and some can't. Do you know which works? I'm basically jus looking at the car being able to recognise my RNS-EPetrolDave said:If you have an 8P A3/S3 then you need a CAN cable, if you have a B7 A4 then a combined KL/CAN cable is recommended, for older A3/A4 models a KL (dual-K) cable is OK.
There's been so many cases on here where people have tried to use VAG-COM versions earlier than 512 with a third party cable and had controller not responding messages. Adding to what Dirk has said, with the Bluetooth module it's advisable to use 607 or later to get a reliable connection.Haaggie said:so, when you only want to program your RNS-E and BT-module, you should do this with VAG COM 4.09 and a 'cheap' third party OBD cable?
