Thread: Interchangeable D3/D4 parts

Be aware that some D3 parts are not interchangeable between the various D3 models, particularly between pre MY07 and MY07 onwards. The D4 is a D3 model update given a new name to go with the 3.0 engine, a more plush interior and various small improvements.

Thanks Graeme. To be a little more clear, I'm comparing a MY07 D3 versus an early D4.

Not a lot of mechanical difference that I know of: D4 has lower suspension roll centres but wishbones should be interchangeable in pairs, shocks are interchangeable although different valving, 2.7 brakes same on both but front mudguards are different to at least pair with their respective bumpers. However no ecu that connects to the high speed canbus can be swapped to the other because of differing canbus protocols without even considering stored VIN restrictions.

Thanks again Graeme.

From what I've read around the last few days, a number of body panels/mouldings seem to fit (some with modifications), but electronics seem to be almost totally new for the D4.
