Default convertible soft roof

The convertible roof has always worked well but now has started a consistent "ping" sound when closed driving. It is silent when the car is station with the engine running. The is no constant "ping" driving with with the roof open, only the single one to confirm it is fixed.
If the roof is opened then closed it gives one ping only to confirm open or close is fixed.
A few minutes later when driving the constant "ping" starts again.
Any ideas please to silent it?

If the hood is locked in either the fully closed or fully open state and the alarm is pinging then the most likely explanation is a faulty micro-switch/sensor (probably one of the locating "brackets" cracked off) - three or four options,
1) get the codes read to identify the faulty sensor/micro-switch or canbus error
2) having found the fault, replace the sensor - if bought from a Volvo dealer many pennies apparently
3) pull the fuse for the "ping" alarm........recommended only as a short term fix
4) contact a breaker for a replacement sensor - "minty" is breaking a C70 rag top at the moment and may have the sensor you are looking for. His mobile number is 07841056796

Cheers

Hmmm...

I had a similar thing happen with my rag top (when I had it). But I don't think what happened with me will be that helpful?

Part way home from doing the shopping, the pinging started.

Then I did the wrong thing! I opened the roof a bit to 'free' the problem and the roof wouldn't even shut! So drove home s-l-o-w-l-y (and one-handed) with my fingers hooked through the gap between the hood and the top of the windscreen to try and stop any further opening. Frozen fingers by the time I got home! So unloaded the shopping.

Luckily, my Volvo indy was just up the road, so drove up there equally gently. And being the great guy he is, he plugged me into his computer. There were a couple of fault codes displayed. But... the codes were not that helpful! Anyway, he used his set up to clear them and we then spent the best part of half-an-hour just opening and closing the roof. Whatever the original fault was, it never reappeared in all the time I had the car. It was just one of those annoying random things.

Sorry, not a lot of help for you, but hopefully, it's just a sensor fault for you.

Thanks I will start by trying to locate the micro/switches you mention, then try cleaning them. If no luck I will try to get someone to local to read codes.
Thanks

Do you have an idea why the ping only sounds when car is moving, then stops eg. at traffic lights? Is this a clue as to which microswitch is the problem?
Thanks

It indicates the roof isn't locked down or locked closed when the car is in motion.
The canbus senses an error if it doesn't receive either of the correct signals so sounds the ping alarm - it acts a fail safe - somewhere in the handbook I think there's a warning words to the effect of "do not drive if the alarm pings".

I think it is confused as it always gives a single ping to confirm full up or down and windows closed.
Sounds like a faulty sensor and I unfortunately need the codes read.

The single ping sounds when the open or close sequence has completed - it only pings continuously if the lock in the full up or full down position and hasn't registered as locked or doesn't register the correct canbus signal for the roof control module when the car is moving.

If any of the micro switches are stuck, damaged or out of their correct position the ping alarm will sound continuously if the car is in motion.
