2016 Continental GTC. I drove for a few 100m with the roof closed but not “bleeped” to signal shut (I had no choice) and now I have a roof fault light. Roof works fine.

Anyone know how to reset it please?

Never reset a light or code without understanding why it was set. Do you have a code reader or someone who can do it for you?

No. I think it had a hissy fit because I didn’t heed the “slow down to 20” warnings. But I was in traffic with a car up my arse and I couldn’t easily slow down or pull over.

I’ve done it before but not for such a distance. I don’t think there is an actual fault.

OK, then my suggestion is to buy yourself a code reader that can deal with your brand of car and do it yourself. Getting someone else to do the job is typically around £80 whereas and buying a half decent code reader/re-setter is around £250. You pays your money and you takes your choice. (No point buying a £70 code reader and finding it can't do anything.)

I’ve got a Bentley tech coming over during the week about something else. I will ask him to take a look. I was hoping there was a user reset.

Whilst waiting for the tech to get in touch, I tried a cheapo OBD reader yesterday. It says "no errors stored" or similar. Do better readers have access to more data? Or is there a specific tool required for my car?

Basic readers are often restricted to the generic OBD codes which are mainly about "emissions" and are the same across all manufacturers.

Over the years manufacturers have developed their own more sophisticated coding, typically called "enhanced codes", which may deal with a plethora of stuff. It's notable, for instance, that the yellow light is still called a CEL (Check Engine Light) even though it may be talking about the transmission, brakes or in this case your roof. I have no personal knowledge of the Bentley/VW group's approach but would imagine they'll be using a system of their own. The fancy reading kit from Bosch is quite pricey so you end up juggling the cost of buying a decent reader against the cost of paying somebody else £80 for a one-off reading. I'm sorry I can't be more helpful.

Thanks for trying!

As predicted, the Bentley chap pulled out a tablet with Bentley software on it and cleared the message. He owed me a favour, so it cost £0.
