Parking/light/seat sounder
Hi
Just mulling over a problem with my sounder which only works with parking aid, lights left on and seat controls when it feels like it. Either all work, or more frequently none. The sounder is new and soldered in satisfactorily. Is it possible that a fault with one of the control modules would affect the others? Thanks. |

I can’t help with your problem, I’m afraid.
Just wondered where you got your new sounder. Mine isn’t working at all. |

Hello Steve,
Why did you renew the sounder, did the original display the same fault? Simon

I got the car last August and in that time until I soldered in the new sounder it never worked. I assumed, (yes, I know the saying) that as the sounder had failed on everything, that it was the most likely culprit. At all times, all the reverse sensors click as they should.

Hi Steve,
I've done some research and the sounder for the Parking Distance Control is unique to that system. There is a separate "gong" for the memory seats and lights warning which appears to be integral with the instrument pack. All three systems use K-bus messages so that could be where your problem lies. When the fault condition next occurs, check that the direction indicator tell-tale lights in the instrument pack work normally. Simon

The chime just needs power and earth, not a difficult concept. As the sensors all click the parking aid is getting both. There is no K-bus fault showing. As you suggested earlier, that would normally impact other things on the K-bus. That logically, (in my warped mind) suggests 2 possibilities, either a poor connection or an intermittent short on the chimer circuit. I foresee prolonged and very irritating diagnostics. I was hoping that a similar problem had been solved on here. Most things generally elicit a solution. |

Thanks Steve, I've learnt something today!
