Thanks, then I know it is normal with a hot pump.


Either way it will be expensive. I could easily change the pump but change the pipes looks complicated (pulling off wiper arms and so on)

Still i don't know the exact fault.




Pipesection 1 95535557951                147 $

Pipesection 2 95535557751                233 $

Electric vacuum pump 95535561702 247 $

Sum about:                                                600 $


I have booked a repair (fault find) at Porsche Center in Stockholm. The problem is that they charge almost 300 $ / hour (2018 august). 

Probably it would be cheaper to book a brain surgeon and if the cost too high I'Il still try to do the job myself.

FYI. Now the problem is solved by Porsche center. It costed me 600$.


They changed pipesection Pipesection 1 95535557951 ( in the order they said 47761900-42)            

It looked very fresh, but obviously there was a leak.


If you don't have a clue - I would try to change this myself since (and then leave to Porsche center if its not the solution):


1. it is fairly easy to replace

2. It is more likely that this part is broken - due to the heat.
