New Owner , issues now

[Coyotecayenne]

Hi just purchased 2005 9pa in UK,  140,000 miles 3.2 V6

 

All seemed ok till the rain today 😞

 

Front windscreen is steaming up badly now,

Parking sensors are now  been totally erratic  for some reason 

Sidelight/Indicator  error now 

 

just wondering if this is a bad earthing problem with wiring 

 

your help is is appreciated thanks

Cayennes are notorious for grounding (earthing) issues.  They also are notorious for the sunroof drains becoming blocked and causing leaks under the carpet where there are wiring harnesses.  Good luck!

Hi thanks, don’t have sunroof so that’s a bonus

Mate of mine told me a way to connect new earth straps so hopefully that will work.

Thanks for reply

Have your battery load tested also. A weak battery can cause all kinds of strange electrical faults.

If the battery is 5 years old or older I suggest you replace it.

[Coyotecayenne]

Thanks Loren, I was told new battery fitted recently but not he’d the chance to 

check yet.

Update 

located Ecu, it looked a corroded around the edges 

Applied ACF50 down into connections 

Hopefully this has worked

You need to track down the leak - either AC drain or roof trains are likely plugged.

Cowl drains are also probably plugged.
