The value isn't put back to 00 to hide anything. But it may well be that modifying some bit, or combination of bits, has other effects (such as internal state changes for instance) that means that reverting the configuration doesn't in of itself restore the original behaviour. We don't have the specifications or a build guide to work against.

VCDS should know that the module is Jetta-specific, unless it's not Jetta-specific, in which case the answer is... I don't know. I would have thought the modules (or software versions at least) would not be shared between vehicle types, but who knows. Again, Ross-tech is your best bet. You can try any of the configurations that you think may yield the desired results. As I said before, I don't think it's likely to do any damage at all, but I can't promise anything.

I tried presets for other models including the GTI. You were right. They didn't do any damage. They did lead to wonky behaviour though. Reverse lights on in park. Dim park lights etc.
Thanks for the help so far.

Leaking Tail Light.

Can't see any gap, but water is in there. Should I drill a tiny hole on the inside (black part) of the lens assembly? It would not affect the lens itself, but not sure if it will cause more issues than it solves....

You went with aftermarket (non OEM) tails, didn't you? Hate to say it, but this sort of thing is much more likely to happen with the eBay aftermarket stuff.

If you drill a hole, you'll just allow more moisture to get in and cloud up the lights on an ongoing basis. They really should be completely airtight. Your best bet is to let the lights sit in the sun (or apply gentle heat) and the moisture will hopefully evaporate. No guarantee this won't happen again of course.

YUP

Ebayer said they will send another set if I send mine, but don't want to swap back to original tails and back again to new led's, so hoping he will go with a deposit from me to send new set and refund once he receives oldies back...
Few...all good. He will send out a replacement set and hold a deposit till the wet one gets back.

The same thing happened to my tails after using a pressure sprayer a bit too enthusiastically to clean the car- and they are original parts. I took the lights off, poured out what I could and then used a hair-drier to completely dry them out. took about 15 min. Couldn't find any cracks or gaps and have been fine since...

Thanks good to know. If the replacement set does the same thing - Ill try your solution. I also bought some flexible clear sealer from Bunnings, so might apply that around the assembly before installing . . .

So what's the current go, then? Go OEM (~$700) or something like the VACAR copy (~$350?)?

How did you end up going with this?
