Had my first SMG Cog Error on my CSL

[billyboysm3]

The first thing I would change is the salmon relay for about £10.

As the cars not done much miles.

Mine lost gears and had flashing cog light. Elms done pressure test on SMG pump and fine, its been fine since relay.

UPDATE.

Replaced GPS. Indy popped it in for me. The cog light is now off. But only have half the box 135r. Thebox will not shift into 246.

Tried to run smg adaptation as assumed this would tell gearbox what was what, but the procedure will not run.

daft q. But is there anything I'm missing.

Car drives ok but will error if you try and shot into 246.side of box.

Do I just need dealer to recalibrate GPS or similar ?

Cheers
John

This guy had the same issue and used GT1 to run the 'Adapt Transmission Fully' adaptation on it:

Not sure what software you used, but may be worth running it again (if you haven't already).

Doesn't lack of 2/4/6 suggest it might be the detent spring, or something in that area?

I got the cog warning (without flashing) yesterday from cold start. I drove it for about a half hour (and all gears worked fine in auto and manual), parked up to nip in Tesco and when I restarted the car, the cog was gone. Didn't come on later in the day when I was returning home

Ordered a couple of Salmon Relays this morning so will replace and hopefully not see the cog again for a while.

so update.

After a new gear position sensor swap, and SMG Adaption all gears are now present and correct, cog has now gone away

cheers for comments.

Just needed adaptations, as the car had learned the old GPS settings, so needed to learn the new settings as the new GPS actually was working, so after the adaption system was ran, all was well again. In my case of course the car was working fine before the cog light came on, as in all gears were there and the car was working, just had the errors 36/37 as well as the cog light (from the errors)

some toys whilst my car was sat in the garage this week.

Good news Jonny time for S6 (DSC Off) and a bit of a thrashing to let the SMG know the optimum setting
