TCU TurboLamik

All of a sudden after removing the megatronic checking all solder joints for continuity(which there is) l plug in to check and now the code changes to 21, this is now getting interesting lol

I have checked all plugs and pins and removed the megatronic it was sealed and all potting in place on the pcb ...there is no errors when put ignition on only when I engage Drive and the wheels start moving then the error occurs

Hi ....the error just came back now TCU pins and pins on plug looks all good although the transmission plug feels a bit loose , I used a pc board solder setup

Thanks for that information.....the car has been driving for 2 months now the error just came up today and just went away by itself after I checked now ...everything seems to be working fine again now

Hi All

So this error is No Rpm signal gearbox sensor 1......any idea on what the issue can be?

Thanks
