Had my first SMG Cog Error on my CSL

[Rick H]

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 :thumbs: time for S6 (DSC Off) and a bit of a thrashing to let the SMG know the optimum setting :supz:

Mines still working fine.

No thrashing for me as still got 900 miles to go before that starts.

So you finally have the engine and car back :thumbs:

Yeah. Just went for a blast to pick some fish and chips up.

A bloke walked over with his misses and said "bloody hell, a real Csl"

Forgot how good it sounds. Drives very very well. Had new suspension and bushes so is like new.

Collected car from garage on Friday, after having a service whilst it was up on the ramps, and all is back to normal, in fact, as the adaptations have been ran its a bit crisper ;0) happy days, took her for a early morning blast and all is again well with the world.

i had the cog come up on Saturday evening, at the same time gear indicator started to flash and car selected neutral, i pulled over switched off and restarted and cog went and i could select a gear.

but since then it can't find gears on the way down the box unless you lift of and let revs die and on the way up it also will not do it with much load.

using auto in a slow shift speed allowed me to get where i needed to go and manual mode was useless.

Anyone had anything similar or know the cause? it almost feels a bit like clutch, its not had one in 82k miles so i'm hoping that could be it.

How often do you drive the car? Id replace Salmon Relay first for £12

Use to be lots 10k a year now not a lot done about 800 miles since last October.

I'll order a Salmon relay and see if that works

[petery]

Wasn't the salmon relay, tried that now, so going to get the fault codes read and see where I go from there

[petery]

Read the fault codes on mine today on a Delphi system I have before it goes into BMW while I'm away.

From the gearbox I have

Fault 48 - Mechanical converter lockup clutch monitoring

Fault 6 - unknown

Fault 92 - Unknown

Anyone know what these mean?

first one to me signals a clutch issue. It has done 82000 miles and is on original clutch, other ones I've googled but not found anything

What does your pump pressure go to when checked?
