Gear Box oil And FOG lights

[MAP]

Hi looking to change my gear box oil on my A3 2008 1.9tdi manual 124k, is the standard manufactures oil ok to use or should I go for something better. Also what size are the fill and drain Allen key bolts. Finally I’m looking to add some fog lights will the wiring loom already be there and if so where should I start looking thanks for any help in sorting this 👍

Hi, I used a Fuchs branded oil on my A6 as I was advised by an oils specialist that this has very high modular test passes and he also informed me that Fuchs have been supplying most of the German car producers for years, the batch I got was on eBay and was about half the price Audi wanted.

With regard to the drain plug that will be on the bottom of the box and the filler plug will be on the side, easy enough to spot, some use hex headed plugs and some standard bolt heads but if you have a fairly comprehensive tool kit this should not be a problem drain . Other than that the only other thing I would advise is that you take the side filler plug out first, I wish I had a tenner for the amount of times I have seen people take the drain plug out first, drain the oil and then cant get the filler plug out, no oil in the box means you are up poo creek, at least if you do it in reverse sequence if you cant remove the plug at least you can drive the car until you can get help.

The fog lights are another matter in so much as the loom for them is probably in place with the plugs but I suspect that if the car was produced with out fogs once fitted this may well be a case of changing the switch panel unless already fitted and then get the fog lights activated using VCDS for which you will need the coding for the lights or possibly have to have the BCM reprogrammed to accept them.

Thanks for the reply Steve very helpful,with regards to the fog lights sounds like it would be easier to wire them in from scratch 👍

No worries, yes I think the fog lights would be better wired from scratch as at least you could go down the route of Can-bus error free bulbs this would mean the BCM will be none the wiser to the extra equipment/load.
