I need to replace my knackered AKE 2.5 V6 TDI engine. I have been told by a replacement engine specialist that a BAU engine will fit. As far as I can tell the BAU engine was the successor to the AKE engine, but have not found anywhere that tells me what the differences are. I am dubious about the swap. Audi UK unofficially say the engine management will be different. Can you help? Can you tell me who's got an AKE engine I can buy as hunting the net is getting me nowhere fast.
