Tf developed a fault last week, seems to go straight to 4th and when slowing down hits 1st and the warning light comes on?
Move to neutral and revs drop, light goes out.
No faults on my ODB2 reader?
Taking some advice I changed the fluid and fluid pan filter, old fluid was dark but smelled OK, some swarf on magnet but everything looked clean up inside.
My guess is electrical? Display by stick shows all modes but dash display will not show D or DSport and cannot change gears maually either with stick or paddles.
Strange thing, if key turned to start pos while in D it lights up??? (But wont start obviously)

Any advice greatly appreciated

Pm Quicksilver (Chris). He is our Guru on the stepspeed.

have had some weird issues myself recently....

ECU seems to over heat, then eventually my gearbox refuses to change/kangeroo's and the rev counter dies...

the Stepspeed box is controlled by the ECU, so its possible you could have a faulty sensor, or even dodgy ECU...

Oz.

The F and TF Steppie has a separate ECU for the gearbox. It's located in the boot in the left rear wing. It takes some inputs from, and provides some to, the engine ECU iirc.

Located GIU in boot and checked conns. Spoken to CVT guy today and suspect electronic fault so getting on T4 to find codes as my Scan XL wont read cvt faults
Thanks for all the input so far

Spoke to MGR technician who dealt with a very similar problem recently and that was inhibitor switch fault.
T4 session booked for tomorrow, £40 + my back teeth
The saga continues

Well, after another chat wit MGR fella I decided top double check ihb. sw conns
One of the female conns on plug side had moved back in the sleeve after I had cleaned it and was replicating the original fault
What a dipstick!!!!!!
So I get to keep my back teeth after all

Thanks to all

I'm very pleased for you. Any 'how to' pics (when you have chance please)?

ave got some pics, will post once sorted

Sorry I havent been around to pick up on this been just a snowed under with work. Glad you got sorted- for future reference you did everything right Other thing I would have suggested is resetting the ecu which is done simply by removing the ecu from the loom, it loses all its learned adaptive info and basically resets to factory settings(worth trying if you get stuck again.)

Thanks Chris

All is well now, even drives better since fluid and filter change
Wil post some pics soon
