| Description of the problem | There have been increasing reports of variocam camshaft drive bolt failures on the 2011 porsche cayenne v8 engines. When these bolts fail, engine damage occurs, and the engine typically stops running. In the case of the turbo model - this can also result in the loss of braking ability since the brakes are powered off a camshaft. There is also a loss of power steering - meaning you have a 4,500lb vehicle without brakes or steering. Porsche had a limited "workshop campaign" for these vehicles that addressed a certain range of vin# in the usa. It is wc-22 (i'm attaching a pdf of it.) the failures are now being reported with increasing frequency in vin#'s not covered by this workshop campaign. The campaign involves replacing the variocam assembly with one assembled with steel bolts rather than aluminum bolts. Earlier versions of this assembly also used steel bolts, and the failures appear limited to ones where the aluminum bolts were used. The most complete discussion on this can be found at: http://www. 6speedonline. Com/forums/cayenne/319690-snapped-camshaft-adjuster-bolt-engine-brake-hydraulics-failure. Html there are other websites and discussions on the same failure. Here is an article on the recall porsche did in china for the same problem: http://europe. Autonews. Com/article/20150209/ane/150209861/porsche-will-recall-some-panamera-cayenne-models-in-china mine has not failed yet - but it appears to be just a matter of time, mine has the aluminum bolts in the assembly. I would ask that porsche extend the workshop campaign to all the vehicles with the aluminum bolts used in the variocam assembly. The failure of both brakes and steering that occurs when these bolts fail is an obvious safety issue with these vehicles. It makes me hesitant to drive the vehicle. I've asked the local dealer about it, and they claim my vehicle is not effected. |
