Hi All

I have a 2004 UK spec 3.2 Cayenne. It all started a week ago when i noticed the rad fan was running for about 30 minutes after i returned home. The temp was half way. The next day the car was dead. The car then jump started and all seemed fine. 3 days later i went to it started as you would expect. I then drove 10 miles got back home and locked the car. Went back to it 10 minutes later and it was dead again but this time it locked the key in the ignition and the indicator lights where all flashing. I managed to get the key released but the small button on the ignition. The car was dead. again jumped started it and noticed cayenne brake proportioning light was on, ABS light, Brake light, Speedo did not work and the car sounds rough under acceleration.

Please help?

Thanks

Tim

 

Replace battery 1st, clear all codes second and re test
