The market has determined that some kind of fragrance is expected to mask the odour of the solvent carriers and fungicide / bactericide / biocide. Additionally, there is a slight risk of allergic reactions to some of these substances. But they may claim a standard of effectiveness - for example EN1276 specifies 99.99% death to bacteria and microorganisms. EN14476 is another standard relevant here. Best to treat the car and then leave it overnight. Plenty to choose from.

A helpful summary. Printed with a couple of the photos in my glovebox ready for the point I can't put up with the weirdness anymore.

VAG recommends you use a VAG specific product. How surprising. Most of the questions you have can be answered by working out what is meant to be sliding on what? Any temperature or environmental constraints? What type of loading? PS Someone who works in a bodyshop is not a lubrication specialist.

You do know more than you think. Hinges, for example, are ancient technology and white lithium or black molybdenum grease will be perfectly fine. On very dry joints I might spray a little thinner grease to help the heavier stuff get in. Wipe off excess afterwards and you're done. The thinner grease I have to hand is Wurth HHS 2000. Good penetration and good adhesion / durability - something WD40 doesn't have. Bonnet release catches are regularly checked but door / boot locks hardly ever unless I notice stiffness. Sunroofs are tricky things with many different requirements. Here's a summary from Krytox of all the challenges you face. ISTR the VW Eos convertible had issues with its roof which were only ameliorated by liberal use of a Krytox product (at vast expense when branded by VW). Dow Corning do make a special lubricant for this kind of application but very hard to find any retail quantities (Molykote G-1033). grease oil lubrication sunroof systems.pdf

I would begin with the aftermarket immobiliser. Often they are hateful little things and sometimes incorrectly installed. But I see your Zeder is just a mechanical device so cannot be part of your issue except for the buzzer. Try disconnecting that. Then my first step would be the correction of your faulty steering wheel. Your parasitic draw suggestion is the right one. But it seems to be intermittent. As far as aftermarket GPS trackers are concerned, you should be looking for any extra wires or piggyback connectors. Easy to say, hard to do. Favourite locations for these would be the fuse and relay blocks. Good luck.

The 2019 workshop manual refers to a special VW tool - T10165 - which just winds the piston back in. The Hilka tool looks as if it does the same job.

The refrigerant gas in your Bora will have been one of the now banned refrigerants. Modern cars are running refrigerant gases which are kinder to the ozone layer - but they do seem to leak a little more and are certainly more expensive. Take your car to a proper A/C specialist rather than the dealer. He will empty your system, refill to the correct level - often with a marker dye to trace if you do have a leak. The seals will be fine and should benefit from the correct amount of gas / lubricant in the system. Max pressure is regulated in the A/C circuit and will not be increased with the correct amount in. The anecdotal statement that regas leads to blown seals omits the question of why were they regassing anyway? Seems to indicate the fault was present before the regas. My wife's 2016 Rapid, with the 1.0 litre engine, always had a quiet chirrup from the A/C from new.

The clima setting of automatic is very clever but, as you've seen, once the system believes everything is fine the air vent flow seems to be very minimal. I've found that moving the fan control off "auto" and selecting manual fan speed at 2 or three gets you a more consistent flow. This is also my solution when four up in colder conditions - the rear passenger windows do start to steam up with four people in the car. Certainly a clever system but not perfect for every situation.

Did mine recently. This video shows how to get the trim panel off. My lights were W5W bulbs which I swapped for LEDs with no issues.

Plenum chamber not draining well? If you park on a slope and it rains water may accumulate in the chamber more than is normal. Sunroof drains?

I successfully installed P0468T on a 18 plate Rapid. From memory it had only P02xxx installed from the factory. Can't say I noticed any changes whatsoever. Maybe a slight change to the graphics but that's about it.

Rather you than me. Here are some of the relevant pages; Trim; cover; window; lifter

From memory, there is a small spring clip inside the key which likes to bid for freedom. Open both your keys up and see if it's missing now on the broken one. U shaped and about 1cm x 0.8cm in plan view (looking down. As far as I know it's not available as a spare so you may have to buy a dead key and rob it of the spring.
