w219 CLS 320- Distronic and Keyless
Engine swap

So I have a weird question.

I have a 2006 w221 320cdi as a replacement for my 2007 w221 320cdi which was written off recently.

We had the car on a jack to access, the jack slipped and punched a hole in the crank case. Engine is written off.

I have my old engine and transmission and ecu from the 2007.

I have someone who can do labour to change the engine for the old one. Potentially transmission as well as have issue with speed sensor.

1. Please can someone confirm if a engine swap using the same ecu will need any programming (I have Xentry and Vediamo)

2. Does anyone know how to virginise the transmission? Or if I swap ecu will it work without programming?
