Desperately need assistance before scrapping my Cayenne

[trevorhp]

Hi Everyone.
Looking for inspiration before finally deciding to finally scrap my 2005
4.5 9PA Cayenne:
Simple story almost 200,000 miles and seldom has given any trouble.

1, Had a leaking connecting pipe on the main coolant hose in the valley.
2. Replaced the hose on the aluminium connector on the large pipe.
3. Renewed the 3 smaller aluminium coolant pipes in the valley as had to cut out the original ones due to silicone sealant applied by someone who replaced the original plastic pipes before I owned the car.
4. Car started fine with no leaks and drove 250 miles with no issues and made a couple of stops on the journey, returned with quite low fuel level.
5. Parked the car overnight and next morning went to start it....No crank

Everything else works fine but no crank
I have PIWIS 111 and it shows a couple of faults:
P1314
P0189
P0185
P1049

I refuelled from cans to half full tank.
I noticed that the door puddle light does not come on along with the red warning light, nor does the fuel pump prime.
All the other door lights work.
No other signs of anything wrong.
I disconnected the fuel line at the rear of the engine and no fuel came out upon opening the door or trying to crank the engine.
No warning lights and No errors in onboard storage.
No door open symbol from any doors when open.
Gear selector shows correct position with lights and symbolon display.




I've ordered new:
Door lock
Starter motor
Ignition switch with key.

I suspect BCM but cannot replace it without coding so too much expenditur to justify this route.


I can't justify any more large expenditure and would appreciate any ideas as to what may cause all these faults in one go.Thanks in advance Trevor in the UK

How old is the battery ? Dieing batteries cause lots of issues with modern vehicles .

Thanks for the information.
I put a new battery on just in case.
But the problem was later fixed.
Thanks Trevor

Starter motor &
Door lock changed and these problems went away.
Just waiting for the next ones to appear.
