  1. My rear deck fan will start up, not immediately but, up to about 15-20 mins after shutting the engine down and may run for 5 -10 mins. I'm in very high ambient temperatures though.
  2. Is the car a 2006 CttS? There was no 2008 turbo S and the standard tyres on the 2009 turbo S were 295/35-21. From the choices above, I'd probably opt for the Pirellis, as I tyre I prefer the Michelin Latitude Sports, but I don't believe that they are available in your size.
  3. I wasn't questioning your methodology, I was merely stating that I would not base a diagnosis on a single reading which is why i have 100% confidence in the results I received. Fact is that during the test, hot engine at idle, the readings were consistently 13.6V and 12.3V and the alternator will maintain a constant voltage for minutes at a time. This a simple test from an easily accessible point which has three fundamental outcomes which can immediately point to the area which needs further investigation.
  4. There is more than one way to skin a cat. :) I would never advocate basing a diagnosis on a single reading; you can repeat the same test about 5 times in a minute and if the values measured are consistent then the test is reliable. The results from the OPs test on the jump terminal, tell him that the earth is OK and that the voltage is either low at the alternator or that the voltage drop is in the cable between the alternator and the jump terminal.
  5. Mine did this and it was a very easily and cheaply fixed selector issue.
  6. It would appear that 158 51 is the US version and 158 31 was fitted to European/ ROW cars from 2005 onwards. I don't what the physical differences are but lighting is one of the areas where US cars often differ from ROW. US PET 955 631 158 51 headlamp /R 1 I8JD I8JD Main headlights with gas-discharge lamps U.S. version, XENON RHD European Pet 955 631 158 31 headlamp /R 05- 1 I8BC I8BC Main headlights with gas-discharge lamps + direction indicators, XENON, right-hand traffic
  7. Before my engine was rebuilt I had the low voltage issue, so while the engine was out I had the voltage regulator and earth strap as a preemptive attempt at a cheap cure. When the engine went back in I still had the issue, so one after another every HD cable in the starter / charging circuit was changed including the front to rear ones; no result, voltage was still low. Completely frustrated I decided to take a look myself. Taking the easy route first, with the engine hot and on load I measured the voltage across the battery directly and then from the +ve terminal to the chassis, both were exactly the same. Moving to the engine bay I measured from the +ve jumper terminal to the engine (13.6V) and then from the jumper terminal to chassis (12.3V) and concluded that the earth strap was faulty. Took the car back to the shop and demonstrated my findings and they said that they had actually checked the earth connections and found that the connections were good. They agreed to test the car using the earth strap from another car in the shop which worked just fine; the shiny new Porsche original earth strap on my car was faulty. A temporary fix was made using a (not very well made up) earth strap from a local electrical shop; I ordered a heavier duty, marine quality, ground strap online and this is what is now fitted to the car. As Ahsai says above, just because it is new or looks OK, don't ignore it when checking.
  8. Good to hear that, I hope you're now enjoying the turbo!
  9. Did you also solve the oil pressure issue?
  10. This, along with the short inner harness, has been an issue on all of the Cayennes I have seen here in the middle east.
  11. Local Porsche dealer had to obtain a code from Germany when I had mine fitted.
  12. You may have a different issue, but the most common cause of this problem is covered here http://www.renntech.org/forums/topic/31161-brake-booster-faulty/
  13. Fact is that the Porsche did do that, and the temps are smoothed out. Between 69C and 97C mine (or either of the other 2 that I've scanned) does not move from the central 80C Norm mark.
  14. A friend of mine who owns my old 2005 CTT has just had the reservoir fail. Car is a 201k ams on original coolant pipes. Total cost at ARM AED 1200.00
  15. I could only guess that you first had an issue which hydrolocked a cylinder whilst under power and the extreme force was transferred to the crankshaft which in turn cracked the crankcase.
  16. I think it needs a new motor unit unless you can strip it and repair the plastic gear drive. Not a particularly unusual problem, the plastics become brittle with age.
  17. Since Porsche considers the markings to be Max and Min, right in the middle would be absolutely fine in my book.
  18. I ran my 09 GTS with DRL on for 3 years with no issues; my current turbo has the auto position so no DRL.
  19. I know that DLR cannot be de-activated in Canada, don't know about Europe. Perhaps it can be done PIWIS or Durametric?
