December 7, 20213 yr Hi all, I've had my 2015 CR-V idtec (2.2) since April, and as the weather has got colder the dash makes some very strange sounds that last for about 45 seconds, this is without starting, just opening the door and sitting down. Does anyone know what it is? It's some sort of electrical sound and seems louder the colder it is! Thanks. Phil.
December 9, 20213 yr It could be the heater flaps re-indexing or other system relays (timer) to prime the engine (fuel, intake, etc)

Thanks.

Thanks. And yesterday which was a mild morning the sound was noticeably quieter, so definitely affected more by the cold.
December 15, 20213 yr Tolerance clearances have changed with the temperature I guess.....at least you'll know how cold it is by the level of noise the car makes 🙂

December 15, 20213 yr Silicon spray is quite safe to use unlike WD40 as it is not oil based and you can liberally spray it under the dash
