I noticed another thing. If you press the DTC button for >10 seconds, you'll lock the button.
In other words: After pressing it for >10 seconds, pushing the button again doesn't do anything at all until you switch off the car.
Anyone knows what this is for? I can imagine that you could want to lock the safety systems if you give the car to your 18 year old son, but in this case it doesn't make sense as the button works again when you restart the car.

Holding DTC for > 10 seconds switches DSC off. Pushing it again switches everything back on. When you say you hold it and it locks it, do you mean it leaves everything enabled, and stops the button being able to disable the traction/stability controls? If so, that sounds like a fault - sounds like it's trying to disable DSC, finding a fault, and locking up. It's not a documented feature.

I press the button and hold it.
1) Immediately it says "DTC" as expected
2) After a couple of seconds is shows the triangle, indicating that you're all on you own
3) Then, after 10...15 seconds, it will switch off everything again (no more yellow warnings)
and from that point on, the button doesn't do a thing. No way to get the DTC or triangle messages unless you restart the car.
You guys should be able to reproduce that. My car is a EU LCI.

I guess it should be the same for all LCI models. Please give it a try. I'll ask my dealer what it's for (next Tuesday), although I don't think they'll know...

An interesting one the other day. Cruise was swtiched off automatically and a message came up on Idrive saying that this was due to slippage. It was round a bend and the road was slippery so was a correct functioning - I just never knew it did that.
Regards,
Regards,
But surely going round a bend with cruise on at a speed that, even to maintain constant speed, causes loss of grip sounds like dangerous verging on barmy ?

I can still enable the cruise control in both modes, no problem at all. If I disable DSC while driving with cruise control, it stays on. And I can then still switch CC on and off, independant of DTC/DSC settings.
It may be a US/EU difference.
