New Owner. P1539 Code


Recommended Posts

Hello Everyone.

I just bought a 1999 911 C2 6 speed. It has 96000 miles. When I received the car off of the transport the CEL was on and rear spoiler light as well. Most of the rear lights didn't work, nor did the rear spoiler. I quickly discovered a mouse had been living in the rear of the car and snacked mainly on the drivers side wiring harness. I removed the rear interior of the car and pulled the harness to the inside of the car and repaired those wires and removed the passenger side tail light and repaired a couple of wires there and on the harness going to to rear spoiler.

I reconnected the battery and all was well until the second drive when the CEl reappeared. I used a basic ODB reader and got the P1539 code.The code is for Camshaft adjustment, bank 2. I cleared the code, and on the second drive the code reappeared. The car idles and runs great. I did a bunch of searching and feel like the Vario Cam solenoid and actuator are functioning correctly because of the smooth idle and strong revving.

I closely inspected the harness on the passenger side of the car for any more mouse marks and didn't see anything. Should I look at the valve actuator or the solenoid or both? There is no point in asking the guy I bought the car from anything about it because obviously he didn't disclose any of these problems with me and I will take it up with him financially once I fix the car.

Any thoughts or suggestions on anything else I should check before I have to take it 3 hours to the nearest Porsche mechanic?

Thanks
Tyler

Get the car scanned by someone knowledgeable with either the Durametric system, a PST II, or PIWIS system; not only to read the codes, but to activate the VarioCam units, and to check the actual cam angles while you are doing it. A smooth idle and strong revving is not particularly meaningful. Once you have run these test, you will know if the system is actually functioning correctly. If it is, you may have more wiring damage elsewhere in the harness.
