... They installed me 5246 (originally 4637) and I may go back and ask why the latest one which I thought was 5921 but now looks like you have a later one wasn't installed.... I originally thought mine was better after the update, but I think it has deteriorated again - probably because it has gone through a cycle of learns.
Am interested in "upgrading" my ECU to the latest firmware too, I'm based near Hatfield, so figure I'll give Hatfield Audi a call and see what they say, though I'm not going to hold my breath! My current software version says 4637 so I'm assuming that there is a much higher update. Does anybody know exactly what the update does and if it is worth it? I've just done a throtte body clean so I am thinking that now may be a good time to go for the update.
