Cayenne GTS Starter Question - need 2nd opinion

Recommended Posts

I need a second opinion.  For the past 5 or 6 months, in the hot or cold, my Pepper would struggle to turnover, but only sometimes.  I was convinced the battery was on its way out.  I replaced the battery with an Interstate, then I hooked it up to a trickle charger to make sure it was fully charged.  Turned the key and the exact same problem. It got much worse over the past few days (prior to the new battery install).  Its now in my garage, thankfully, and when I turn the key, it almost seems like the starter is seized and wont turn-over even the slightest bit.  It clicks for a second then seems to suck all the life from the battery and nothing.  

 

I cannot think of any other culprit other than the starter.  I've been the 'Valley of Coolant' before, so its not a major worry to get at it.  Just want a second opinion.  Oh, and anything else I should update / mod while I have it apart?  I have a new thermostat, (water pump is already new), plugs, coil packs will be done when I have it apart.  

 

Thanks!

It sounds like it since you have a brand new battery. The other possibility is corroded cables that you can do some voltage drop tests to confirm or rule out.

Note the test probe needs to contact the battery posts and not the cable terminals. The readings are taken when you try to crank the engine.

      My front wheel was making a rattling noise for about the last week, and this morning as I drove out of my driveway and turned the wheel, I could hear a loud popping noise coming from my wheel whenever I turned. My best guess is that I drove over a pothole and the control arm / bushing moved out of place. Would this be covered under the OE warranty? Or should I take it to a mechanic?

      Hi there, my Cayenne is telling me my driver's side door is open when it is not. This is causing the dome light to stay on. Not sure what the issue is and if can be fixed easily. Any info given is greatly appreciated, thanks!

      Hello everyone,
                Does anyone have or know where I may have the bolt torque specs for a 2008 Cayenne Turbo? I need pretty much the specifications for all the bolts and nuts that would be included in a block replacement. I'm getting the back rebuilt by 928 Motorsports and reinstalling with an experienced friend. However, it's nearly impossible to find the specs for these motors. Additionally, if there's a place where I could find a complete 957 workshop manual, could someone please advise? Thank you.

      Just wanted to say thanks to the community helped answer some questions about the scoring on my 2008 CTT 957. My next question is, does anyone know where I may purchase a complete engine seals and gasket kit for a 2008 Cayenne Turbo? Or if these are unavailable as a whole unit, had anyone rebuilt their engine from the cylinder scoring or something similar and have a parts list of required seals and gaskets which need changed? Additionally, are there any other suggestions on parts that I should change some I'll have the motor apart? Anything would help at this point. Thanks
