The engine check light on my Cayenne came on a couple of weeks ago and is now continuously on when I am driving the car. I have booked my car into a Porsche Indy for an OBD check this week to see what the fault code is and hopefully they will resolve the problem. When I contacted the OPD and the Porsche Indy both explained it was most likely to be an emissions issue, probably the DPF and that I should go on a long drive in manual gear change mode and to keep the revs over 2,500 rpm. I have since been on a few long drives, no change in performance or mpg and the car drives as it had done previously before the engine check light came on. My question really, is if it had been the DPF then the warning light specific to this would have appeared also ? if anyone has had similar issues I would appreciate to hear what the problem was and approximate costs to resolve the matter.
