Part Number IAW-45 WD45.01-IC60 MED503C 64834312.
It has the triacs screwed into the aluminum cases rather than having the hooked clips securing them in place.
Just wondering is it an ecu revision as most of the ecu's i have seen have the triacs p clipped to the case.

this is the link for the ecu i just bought.

 

if standard as stated in the ad if it has a white CO screw it's a L6 as fitted in 2w/d saffs if a yellow screw then it's a L1 as fitted in the 3dr!
