  1. Rather than providing an item number which, over time, will go obsolete, I suggest searching eBay, Amazon, etc using the a combination of the following key words: Universal Radiator Cooling System Pressure Test Tester Kit Using a combination of these words & my photos for comparison, you'll soon find what you're looking for. As I say. this kit appears to be non-branded & sold by many outlets - expect to pay between UK £40 ~ £60. Watch carefully where it being shipped from - especially if you need it within a few days!
  2. Cayenne 2003 4.5S I needed to pressure test my coolant system to identify a leak that, when hot, could be smelt but not seen & when cold didn't leak! I wanted to buy a Coolant Pressure Test Kit but was not sure which one to buy. During my research, I noticed there was one type of generic non-branded 'universal' kit that appeared multiple times on the general market (eBay & Amazon for instance).. Most listing for this generic kit listed all the car types it would fit but of course, Porsche was not listed - however, a few VAG applications were listed so I took a punt & orde
  3. 2003 4.5 S Interior Heater Fan Speed Control – Manual override. When the exterior temperature is higher than the set interior temperature (which isn’t very often in the UK), the heater fan usually runs flat out with all the associated indication bars illuminated on the centre console display. My question is, can I manually slow the fan speed down & if so, using what settings. I think I’ve tried all the settings (auto, mono, eco, etc). When I manually slow the fan down using the fan toggle switch, the associated indication bars drop too but as soon as I release the switch, th
  4. I've attached a picture of the whole circuit board / circuit card which, compared with your photo suggests your surface-mounted device (SMD) is missing - but the detail of my picture is not good enough to see the SMD value. If you still have the SMD that fell off, then look to see if it has numbers printed on the brown / grey ceramic (the middle bit). If you can find these numbers, an internet search should get you the SMD value or PM me & I'll try & get that for you. I have another thought though. Looking at your photo & the state of the solder pads, I have to sa
  5. Febi Bilstein Nº 37820 Amazon UK Stock Nº B00F3CI5DE Here's my Amazon UK 5 star review: Identical replacement for Porsche Cayenne 955 (2003-2006) handbrake foot pedal gas strut. The gas strut that this replaced was the original OEM unit (date coded 2003) & comparing old with new, all the printed ident & safety warnings are identical - the only difference being the date code. I swapped this out in about 15 mins. There's plenty of online tutorials to follow if you're unsure what to do - try renntech.org
  6. On my UK spec 2003 S, I use either socket in the boot - they remain constant live even if the ignition has been of for hours / days (I say this because newer Ford sockets are timed to switch off about an hour after ignition off). Also, I think running the charger wire through the boot shut is also a less convoluted route than running through one of the passenger door shuts.
  7. I wanted to swap-out the standard 5W filament side lights on my 2003 Cayenne S for brighter LED versions. I had a few failed attempts as although many sellers claimed their units were error free, my Cayenne S decided otherwise & still threw-up error messages each time the sidelights were switched-on. All sellers refunded me without quibble – perhaps they knew their error-free claims were a bit of a stretch. Anyhow, problem solved with these units: UK eBay item number 301792310390 - 5W CREE LED 501/W5W CANBUS ERROR FREE SIDELIGHT BULBS Each unit uses 1 x 5w Cree LED chip with p
  8. I totally agree with running CTEK every week - but that will only condition the battery under the seat. You might want to look at this thread too: http://www.renntech.org/forums/topic/49039-2003-cayenne-s-dual-battery-desulphation-charging/?hl=battery
  9. Here’s an update from my original posting I have determined that charging via the under-bonnet terminals or via any 12V Cigarette / Aux socket will only charge the battery located under the seat – it will not charge the battery under the spare wheel. It appears that the battery located under the spare wheel can only be charged via the alternator – so only when the car is running. I have run the CTEK desulphation & recondition cycles & the condition of the battery located under the seat appears to have improved – on the button strong cranking with no error codes thrown up. I
  10. Thanks for posting this extract Loren - it does fill some gaps in my knowledge but I'm still not clear which, in their words, is the main battery and the backup (2nd) battery - but unless I'm told otherwise, I'll assume for now that the backup (2nd) battery is the one under the spare wheel. This point is interesting: The backup battery is disconnected from the vehicle electrical system when the engine is switched off Based on this statement, it sounds that unless the battery terminals are physically accessed, it's not possible to charge the the backup (2nd) battery except by running the e
  11. After standing for a week or two, my Cayenne’s battery power drops - the engine starts but the cranking is slow, it’s creating temporary dash error messages & the comfort settings reset to factory – not good. I don’t know the age of the current batteries – there’s no record of them ever being changed – so I was about to bite the bullet & buy 2 new batteries at a cost of approx. GBP 300.00. Then I got to read a number of accounts saying that sulphation is the principal cause of power loss in lead-acid batteries & that this effect can be reversed – seemingly dead or dying batter
  12. .... and for anyone else still unsure, search "Electric Mirror Switch Controls Both Mirrors :o(" within this forum - or read the owners manual.
  13. I had the mirror glass out my 2003 S a few weeks ago to replace the ‘puddle light’ bulb. I found a tutorial from I-don’t-know-where but basically: Using the mirror position rocker switch, tilt the mirror glass so it’s looking as much as possible towards the car door Get your fingers between the mirror shell & in behind the mirror glass Gently pull the mirror glass out of the mirror shell - the retaining clips will yield - eventually To replace the mirror glass, just align the mirror glass with the aperture & push back in – it will click back in place. Being gentle is key as there ar
