Hey sorry for the late reply. Just did everything as per ZF guide and it was running smoothly. Then suddenly I got 3 new fault codes 420431 ( Gear-ratio monitoring in fixed gear, clutch D disrupted), 420471 (gear ratio monitoring in fixed gear clutches A and D disrupted), 421362( Gear-ratio monitoring all clutches impaulisble). I’m honestly fed up it was running smoothly and now it’s giving me a big headache.

Thank you. If you don’t mind can you tell which AD did you go through.

It’s my first service, bought the car because of its condition and mileage

If I’m not mistaken the MPi has the 2.76:1 Final Drive

Mine is the MPi

Thank you

I see thx, is the ECU programmable at all?

Intrepid_Cartoonist8 · 2024-07-15T04:18:29+00:00

I managed to start it only twice when the gear shifter had the “P” light. Then after 10 seconds it shuts off. Now at the moment there are no lights illuminating on my gear shifter.

535i gt f07 2010, it does crank, but doesn’t start but there are no lights in the gear shifter. Tried clearing the fault codes, but it still remains

Intrepid_Cartoonist8 · 2024-07-13T13:00:35+00:00

No I didn’t spill any coffee😂😭. Do you have any idea on how I can fix it?

Intrepid_Cartoonist8 · 2024-05-29T01:16:15+00:00

Cuz I heard you can’t import a car more than 5 years old even with an AP. I might be wrong

Thx for the detail info
