Interesting. According to Ebay they're the same but I think you're right. Do you know the correct part number just out of interest?Before I thought of swapping the control unit from the other door, I bought a second hand unit from camper van bits. It didn't work , I think because it's for a T6 rather than T5......If anyone has a genuine use for it they can have it for the price of postage...number on it is 7E0 959 243 D
