2012 Cayenne S.
Car just won't start with the battery fully charged. When I try to start I hear a single click.. nothing else. I checked the battery and it shows 13.89v. All the lights inside including the dash, blinkers, tail light, headlights work just fine... but the engine is not getting any power I think...
I tried to jump start the car, but the car is getting no power whatsoever when I connect an external battery via the jump start terminals. Not even a single light... it's completely dead.
I think there is a disconnect between the main power distributor and the fuse box in the engine compartment. Could it be the relay 433 in the engine bay fuse box? If the relay goes bad, would it completely cut off the power to the engine?
Anyone has the wiring diagram? I'd greatly appreciate any help on this. Thanks!
I have a 996 3.4l (1999) tiptronic with 140'000km. The engine was rebuild at 80'000km and the tiptronic rebuild at 100'000km. I face a strange problem since many month. I try to explain symptom in chronological order. - When it rain during the night, I need to start two time the car. The car start alway from the first power on, but no power at all. I need just to power off and re power on and the car work fine. - One month after, the car is running on 4-5 cylinder after the second power on... lot of missfire. - The garagist change all 6 spark, 6 coil, the AOS (leak problem), the MAF and the two lamda probe...
Now the car run almost good except: ans this is my question. Could you help? When i drive slowly (following car) between 1'500 and 2'000 rpm (rpm important) in 3 or 4 gear (tiptronic) and I would like to speed up to overtake a car, the engine do not ramp up rpm, lot of missfire, the gear do not swith to 2 quickly and accelerate...! When i accelerate from 3'000 to 6'000 no problem the car run very well. Now, the garage tell me it is a tiptronic problem...? Could you help me on the road to find a solution ? Thanks in advance
