Update: replaced camshaft sensors and timing chain tensioner - both fairly easy to do. P0017 P0016 code remains. Next step is removing valve covers to check timing and inspect chain/guides. May also remove lower oil pan to check for any timing chain debris. Slight weeping at valve covers and lower oil pan gaskets so they’ll get replaced.

If timing is off, I have OEM timing tools so I will retime and report back, if damage to any components is found, will disassemble front end and do entire timing chain/guide/cover gasket job.

 

Would it have been a requirement to have disconnected the battery prior to having performed the motor mount(s) job?

What does the service manual state?

It sounds to me as though your electrical/electronic troubles started with disconnecting components while the battery was
connected.

As for a PDK fluid change and running the transmission through the gears as a part of the process, IIRC, that procedure has been
described by other forum members several times over the last few years (check the posts in the PDK DIY thread(s)).


BTW, the code noted in the thread's title - was that not present before you initiated the motor mount(s) R&R? Or, had you not run and
diagnostics prior to the procedure?


Good luck!

The only thing I disconnected for motor mount job was the electronic steering rack, which has no fault codes. No other wires were messed with. I already did the PDK service, I don’t need instructions on that. I bought the car 2 weeks ago, the check engine light with timing codes was not present when I bought it, I scanned the car before purchase. It did feel a little sluggish. However I daily drive a Tesla and that may be why it feels sluggish. Anyways, going to remove valve covers today and check timing with OEM timing tools. Let’s see if I find anything.

For those just joining. 15 Macan S 118K miles - P0344 P0016 P0017, some misfire, CEL, PSM fault, sluggish. Replaced tensioner and swapped cam shaft actuators/sensors with no luck. Per other threads on Cayenne with these codes, it seems as if timing chain is stretched or guides are broken/breaking. Going to figure it out.

 

How was doing the engine mounts? Just recently did my transmission mounts but it didn’t fix some of the NVH in the cabin.

 

Had to drop the subframe, so a lift is needed. Would of been a PITA doing it on the floor. But if you have access to a lift, it’s not hard at all, just a bunch of disconnecting suspension component. Drive side mount bolt is a pain, took me about 30 minutes just to get that bolt out. Broke 3 harbor freight extensions/swivel adaptors in the process, but with the right socket and extension combination it should be easier. Otherwise it’s a very satisfying repair as the car feels new again afterwards! Good idea to inspect suspension bushes and replace during this time too since it has to come off anyways.

 

Hello all, this thread will be done for, making a new thread to follow along the repair of destroyed timing chain guides on my Macan. Stay tuned. Thanks!
