406 MK2 RFV ECU Error

Post by adinindu » Sun Jun 25, 2017 2:04 pm

I have a 99' 406 D9(MK2) originally came with an autobox. When i bought it about year ago, it was converted to a manual transmission. After few months of driving car has given many symptoms referring and ECU error. Today when i was checking the car with PP2000 for some error code, car suddenly died. Now i get only Immo Fault. Car has a XU10J4R engine. I have another ECU which came for a RFV manual. Before i try it on my car, was checking the compatibility. I got some weird info. Though car is a RFV, ECU part number suggest its a RFY. Anyway to get this solved? I dont have access to Service Box. How do i get partnumber of the original ECU came with the car.

Help would really appreciated.
