Yellow Cog fault

niall1 · 09-05-2023, 11:05 AM

Hi all,

In a bit of a panic as I'm supposed to be heading to the 20th anniversary gathering at the end of the month.

The car has been parked up since last summer. I brought it out for an oil change and its annual National Car Test (NCT) in March. The yellow cog flashed up but cleared when the mechanic was driving it. On the way home from the garage the Yellow Cog fault light stayed on and the car stuck in fourth and cut out abandoning me on the side of the road. I turned the car on and off a few times and it went back into neutral, started and I limped home. I brought it back to the garage to replace the 'salmon relay' but the yellow cog light stays on permanently now. Are there two salon relays as the mechanic thinks the one he replaced is for the cold start?

Any help or guidance would be greatly appreciated!

Thanks
Niall

need to read the codes first

Fault code is ?SMG shift sequence?.
Any idea what that means

you could try lubricating the shift linkage on top of the gear box
what are reading the codes with is there a fault code number

I was trying to upload a picture of the error code:
017 - 11 SMG Shift sequence
