Warning Lights

[Dartmoor]

Just had 4 warning messages together looks like a Christmas Tree

Hand break error
No all wheel sys only rear drive
ABS/PSM failure
All wheel overload Only rear-wh drive

Porsche Assist found a speed sensor error, don't know if it is related to previous Transfer Box issues?

Going into dealership tomorrow. Interested to hear any thoughts or experiences?

Please let us know what they said. I am no expert but I can't think how a speed sensor failure would be related to transfer box.

Yep. Another transfer box replaced, now on number 3. I diagnosed it last March!. Currently testing to see why warning lights are coming on. Sounds like Transfer Box overheating has knocked out a sensor?

Three transfer boxes!! I presume on the same car?
Can you give us the mileage when each of them were replaced?

I thought Porsche had engineered a solution to this problem?

Interesting, as I had my first replacement fitted last week and I'm pretty sure it is still doing the same little lurch, when pulling away with lock on?

Thought they'd got to the bottom of these boxes, ie: improved the design?

First box started going about 17k replaced at 19k which started to fail gain at 23k (9 months later). It appears that the overheating transfer box might have knocked out a sensor hence the light display?
