loys Posted February 3, 2003 Report Share Posted February 3, 2003 Well i was with my car at the garage where they tried to read out my car with a system from Bosch. But the system couldn't get a connection with my car. 2 weeks earlier they serviced my car and it worked. Went to some other dealers and they also couldn't get a connection. They all said of known error when there was a non-Audi car-radio installed. But mine is fitted more then a year ago. Does this sound familiar for someone ? Please help !

loys Posted February 5, 2003 Author Report Share Posted February 5, 2003 Went back to the garage yesterday and disconnected the radio. Still no connection !!! Link to comment Share on other sites More sharing options...
Scotty Posted February 5, 2003 Report Share Posted February 5, 2003 I've only had two problems like this. One was one Tony's banana - I didn't know at the time but it left him without radio and he had to get it reactivated. The other one was on my car a few weeks ago. VAG_COM dropped the connection to the radio whilst in diag mode. It wouldn't reconnect and DIAG! was displayed all the time on the DIS. I pulled the fuse, entered the safety code and all was then OK.

loys Posted February 5, 2003 Author Report Share Posted February 5, 2003 Scotty, Which fuse do you mean ?? From the car or from the VAG.COM ? Sorry but i'm not familiar with the VAG.COM and my garage is using a Bosch FSA system. Will it help if i disconnect the battery for a while ?

I've never interrogated a radio that is not OE. If you disconnect the battery I think you then need to reset the airbag warning lights Link to comment Share on other sites More sharing options...
loys Posted February 6, 2003 Author Report Share Posted February 6, 2003 I did the test they described in the aftermarket radio article. I meassured 2,3 volts on the K-line so i won't be having this problem. But what is blocking my communication then ? Think i will go for the hard reset: unplug the battery !

Mo-S3 Posted February 6, 2003 Report Share Posted February 6, 2003 If you were to disconnect the fuse to the radio and try the vag com then should it work ? or will the radio have to be modified as per instructions from ross-tech? Link to comment Share on other sites More sharing options...
loys Posted February 6, 2003 Author Report Share Posted February 6, 2003 I already tried with the radio disconnected (is the same as the mod which ross-tech gives) but it didn't work ! Did the meassuring, and meassured 2,3 volts. That's under the 9 volts so there's no 12+ on the K-Line ! The radio isn't the problem i'm afraid !
