yes I get the same. The car is going back to SMC tomorrow for them to try and fix it.

My SMC dealer fixed this problem. He said it was related to "wire routing and the frequency of a light bulb affecting the volumetric sensor". Whatever that means, the problem has now gone away. I suggest you consider returning your car to the dealer for modification.

Sounds like the power wire feeding the interia light ( that comes on with the remote press) is interfering with the internal motion detector the alarm uses.

Thanks for the heads up I've booked the car in but my earliest appointment at my local Motovogue is the 23rd of march with a courtesy car that's about two months away, absolutely shocking long time to wait if you want a courtesy car
