Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1Original post

I noticed after getting my new 2007 Cayman S last Thursday that when the headlights and fog lights are on, one of the passenger side brake light bulbs does not illuminate as brightly as the drivers side when the brake pedal is pressed. My local Porsche service rep is telling me this is normal for all German made cars, this sounds like a line of ****. Can anyone else confirm please?

POST 2Original post

No its not a load of ****. See the FAQ The Cayman Club - FAQ: Miscellaneous . Most likely you got the rear fogs on.

POST 3Original post

This made me laugh..... Yep...its true....the passenger side has no rear fog lamp....intentionally. If you want to see something else that you are not used to seeing.....as you park, turn your signal light indicator on (flashing either to left or right). Then turn the car off, get out,shut the door, lock it....and go look at the front of your car. Have fun.

POST 4Original post

this is not unique to german cars. in fact, it may be standard in the industry...at least the volvo that i had also had only one rear fog light.

POST 5Original post

Wierd! I thought for sure she was blowing smoke up my skirt! Thanks!

POST 6Original post

instead of pulling it out 2 clicks like you're doing to turn your fogs on....just pull it out one click

POST 7Original post

100% correct. You'd be surprised how many Porsches I see driving around with this fog light on. I think the local dealer is forgetting to tell people about this.

POST 8Original post

And dare I say owner's aren't reading the manual either.... sorry couldn't resist.

POST 9Original post

^^i see it all the time as well. Makes me want to ride up next to them and tell them to push it in one click

POST 10Original post

Now, Santa Fe... You know that there are several Caymans that got shipped here without those pesky books...

POST 11Original post

Sounds like the "problem" with my Boxster in '97. The official Porsche answer then (probably now also) was that the USA cars were not wired to allow both rear fog lights to come on. There was a "fix" using a jumper in the rear wiring harness that was on Porsche Pete's Boxster board. It may still be there. Something similar may allow both of the Cayman's rear fog light to be on. The one click, two click switch position contros the front (only) or front and rear light to be on. The turn signal in either the left or right position with the key removed is to accomodate street side parking in poorly lit areas, primarily in Europe. John B.

POST 13Original post

And then it no longer looks like a fog light to those following but as tail lights thereby defeating the purpose. Think about it. By the way non-US cars don't have both on either.

POST 14Original post

The one fog light at the rear happened in Europe a few years ago. People were riding in the wet, not fog, and blinding everybody, and more to the point you couldn’t see if they braked, so they rated that the off side only (right in UK) left on mainland Europe and the States should be the fog light and should you hit the brakes then it is still visible that your braking !!! ................suppose it's logical really.

POST 15Original post

I think it is still legal to have both on in the UK though if you only have one it has to be on the right (UK).

POST 16Original post

Yea think your right Nick, but, it's now illegal for new cars to have 2 working foglights at the rear. I Think for the reason of not seeing brake lights.

POST 17Original post

dont think that applies to all cars, my C4 has 2 rear fog lights, but the are not integrated with the taillights This is NOT my car as I dont have pix of my car's rear! ________________________ "Sir! We're surrounded!" - "Excellent! We can shoot in any direction!" A good car will get you from point A to point B. A great car... will just get you into trouble!

POST 18Original post

Shame on them but you do know that you can download one from the Cayman Club's file section and be on your way with no excuses don't you?
