After starting my 2003 C4S about 2 weeks ago I got a CEL. I immediately took it to my independent Porsche shop. The fault codes: P1325 Inlet Camshaft Bank 2 - Signal Implausible. P0300, P0304, P0306 and P0305, which are Misfires on Cylinder 1, 6 and 5 My Mechanic cleared the code, told me to drive it and come back after the weekend. I drove it for about 70 miles, CEL didn't come back, took it back to the shop. The mechanic told me that that the P1325 came back (but no light). They kept the car for couple of days to run more diagnostics. They changed the oil, inspected the filter, and it looked fine. Switched Bank2 sensor with Bank 1, and still got the code on bank 2. Valve lift tested fine, Ohm tested actuators and that was fine. Eventually they told me they weren't sure what the problem was, and suggested I should take it to the dealership because they have the latest diagnostic tools. The car has little over 54k mi and sounds, idles and drives very well and the mechanic reiterated that fact. They mentioned that they got a strange reading "Adaption Angle = -128 degrees” which didn't make sense to them. One of the mechanics was leaning towards an electrical problem, but they didn't have the proper tools to diagnose it. I finally took it to the dealer, and then I got a call from the service advisor telling me that they ran their own diagnostics and they determined it is the Cam Adjuster. They gave me quote for $3700 to fix. Ouch! Is it possible that the cam can go off just like that? Do you agree that the next step is to open the cam and fix the adjuster? Is there any other troubleshooting they can do? What do you think? I appreciate your help and ideas. Thanks!
