RKD in OKC

Peril sensitive headlamp option. Lights go out so you can't see what you are about to hit so your blood pressure stays normal.


Had a Jeep Cherokee that the rear windscreen washer would spray out the passenger rear wheel well like a dog on a fire hydrant.

Resistance builds up in the switch contacts for the X-Bus - X-Bus feeds headlight, driving/foglights, brakes, HVAC...

So operating any of those items can overload the switch then everything drops out - wiggling the switch can often restore function temporarily..

Very cool. Thanks Alan. It's amazing that no matter how crazy the question, Rennlist always has the answer.

Thanks!

Moral to the story.... Never hang a keyring full of keys there. This will help extend the life of your switch.

Always use a single ignition key with a Porsche fob..

I've had a symptom like this before, and found out it was a loose battery hold down... Battery was shifting and shorting!

I was thinking he is braking way to late, and the car was flinching

I dunno what it is but someone needs to add this to a Tshirt with other 928'isms

Hi Guys - newby here with the same problem. I just picked up the car in Barcelona Spain and drove back to Munich Germany. This pretty comedy problem decided to raise its head just after dark as we crossed the Alps from Italy into Austria.

So! I know this is an old thread but was the ignition barrel the culprit. I dont think they are are $75 any more! Alos my key is TERRIBLE! it looks like it was cut by a cave man! Perhaps this alone could wear the barrel and cause this problem??

Thanks in advance.

It is the ignition switch - just the electrical part that is at fault for this (and it is still quite cheap ~$100). No need to change the lock barrel for this electrical problem, the switch part just screws on at the back, and has a plug connector to the loom - quite easy to replace - the only issue is accessing it.

928 keys are not cut like traditional keys so they look very different, make sure you have a real problem with the keys before you assume anything needs to be changed. Do the locks work OK in the door & hatch?, if so reserve judgement until after you replace the ignition switch.

Thanks Alan! - Good to know - time to shop for parts! I happen to have found another maroon binnacle cover so that will get rid of some nasty cracks.

While I am there I will also do the following.

- fix anything binnacle end of the wobbly volt meter.
- Replace old dead lights.
- Clean up electrical connections.
- General hoover and clean up behind the steering column.

Any other suggestions of things worth doing while I am back there?
