Thread: Double beep on lock and unlock

I think it's a setting in the CCF.

I've checked the "as built" ccf, under safety/security and locking, and "vehicle horn on alarm enable" is set to yes.

It says 63% of cars were set to yes from factory.

If that is true, I'm guessing a lot of dealers turned it off when new.

I can't currently alter the CCF to test.

Also my post title is incorrect, the horn beeps once on lock, twice on unlock.

On the D4 beep once on lock and twice on unlock is correct. If a lat h sensor is faulty, it won't lock the car and double beeps.
