Bought two secondhand MFD’s today to replace my faulty TS MFD.
One is an 8V MFD and the other is a 16V MFD. The identification numbers on the units are almost exactly the same except the last number is different on all of them including my TS’s MFD.
8V MFD number 500.205/001/004 605
8
16V MFD number 500.205/001/004/605
4
16V Turbo MFD number 500.205/001/004/605
3
Tested them on my 5 door (Kadett 8v) and my Saloon (Astra TS) and works.
They are interchangeable between the engine size (ECU’s). Now why would they have different last numbers?
Maybe its something to do with the Speed and averages that’s received from the clocks or ECU?
8V (20SEH) clocks max speed is 220 km/h
16V (20XE) clocks max speed is 240 km/h
16V Turbo (20LET) clock max speed is 280 km/h
When I have time, ill test this speed theory with the different MFD doing let say at 100 km/h clock speed.
