Rear fog left side not working

My 996 has only ever had right side rear fog operating, despite intact bulb and connections on left side. I appreciate a right side rear fog is all that is necessary (in UK) but I want to get the left side working for European travel. Is there something in settings that swaps right to left or switches on the redundant lamp?

I think, by design most cars now only have a single foglight - and it's the "offside" as you have found. There was a directive that rear fogs had to have physical seperation of a given distance from the brake lights - and I think the genreally accepted solution was to only use one side (offside) As such the activation of the "other side" is based on the system wide country coding of the car - not something that is swappable from the menu's ( and would like lead to a number of oddities with other systems if done with diagnostics). I have never seen any law or requirement for changing the side of the foglight for driving in Europe. MOT guidelines are to only look for 1 that is centrally or offside mounted. https://www.gov.uk/guidance/mot-ins...ectors-and-electrical-equipment#section-4-5-1 I know some folks have "wired across" from the offside to the nearside - although they typically do that because they bought after market lights from "less expensive" suppliers - who always seem to only populate the left hand light ( bigger market) - so in that case people get the left one working by wiring across from the right. Depends on how much it matters to you - but I think at best you are in looking a "dirty" wiring hacks - I think, leave as is personally.

Thanks for that. I appreciate the U.K. regs but french gendarmes seem to have an alternative opinion for cars on their roads but maybe it’s a car with a UK sticker that is the problem. If the side that works is just decided by “system wide country coding”, I guess the bulb inserted in the other side (has been there from new) is just intended as a spare.

However, I am confused regarding :- I know some folks have "wired across" from the offside to the nearside - although they typically do that because they bought after market lights from "less expensive" suppliers - who always seem to only populate the left hand light ( bigger market) - so in that case people get the left one working by wiring across from the right. I presumed you meant U.K. owners who are replacing a broken light cluster. But if replacing a broken left cluster (with a ‘less expensive’ or otherwise) why would you need to hard wire a connection from the right side if the left side fog lamp is not needed anyway.

Not needed but some folks appear to not notice that its extremely common for a single fog light and get a bit obsessed with making them both work. On the "less expensive" side - people buy them (led typically) from germany - and they come configured only to have the uk near side light working ( i.e. the wrong side) - which the UK cars don't power, so they then wire from right to left, get one working, and then fail an MOT...... if the tester notices. As to the French requiring it - never ever had an issue, in the Porsche or the daily driver focus ( or the toyota it replaced). Check with the RAC or the AA - but I have never heard of it being a requirement or an issue. Unlike headlights - I have had my headlights checked for beam deflection by french police in the Porsche - mine has a manual "switch/lever" in the headlight bodies that masks the (uk) nearside flick up on low beam. Different if you want to register a UK spec car in France but not for a visit from what I read.

Yes I have the same lever and always use it in France, the car is often there, and the digital speedo’s mph to kph switch is also useful.
