Have not been on this forum for a while since my 09 CTTS was super reliable. It has 250k km now and still drives like a dream. Loving it.

I had the truck rear-ended by a Honda on the highway, the muffler and lower bumper were replaced. After taking it back from the Porsche body shop the truck was shaking badly at idle and the 1373, 0421,0431, 1352, 1377, 1378 codes showed up. Body shop claimed that it was not their responsibility. The truck had very rough idle and very noticeable ticking noise.

I flushed the engine oil and nothing happened. After doing some research online, I replaced part #17 (Hydraulic Valve - Genuine Porsche G94810530803) on the driver side at my buddy's shop. It was held by 2 screws and was done from underneath the truck. Nothing else was removed other than the plastic panel under the car. Cleared the code and they never came back. Apparently, this valve is part of the VarioCam Plus that changes the opening heights of the lifters.

Local Porsche dealer told me that these valves fail all the time. As a result, they have these parts in stock.

Hope this would help fellow Cayenne owners.
