Default Blocked Drains

Yes... The D3 suffers from them as much as the D2. And they're in a similar place.

Although the electronics units are mostly in sealed boxes under the carpet, some are vulnerable to water ingress, one of which being the ingition/lock module which controls the keyless entry and start, along with the ignition barrel.

Check the drains regularly, or this module (amongst others) may be killed off.

You'll also see water coming in down the passenger side centre console as it gets into the pollen filter and through that way. You could be looking at 2 weeks in the garage drying out the carpets.

Is there an official or otherwise documented procedure to clean and check them? Drano? H2SO4? C4?
TIA,
Tom

Cleaning is usually just a matter of making sure that nothing has obviously blocked them and sending water through at mains pressure (or air if you have a compressor).

Following my conversation today with Richard regarding the drains I decided to check the condition of mine. I knew they weren't completely blocked as water did run through but I never realised they were as bad as they were.

This is the bulkhead drains

The good news is you can access them from below the vehicle if you can raise the vehicle high enough, the bad news is you will need a ramp, the good news is I have a ramp



I'm sure next you take your car in for an MOT and speak nicely to the examiner they will clean the pipes for you as it only takes a couple of minutes with a long screwdriver or similar tool to prod the crud out.

The good news is nothing needs to be removed to do this from underneath the vehicle. With the vehicle raised locate the gearbox mountings, then looking slightly towards the front of the vehicle on the transmission tunnel you should be able to see the pipes

This is the off-side




The near side looks easier to gain access, but the exhaust gets in the way so a long screwdriver was used to clear the rubbish out.
I then stuck the vacuum cleaner into the end of the pipes and sucked through any crap that was remaining.


A couple of pictures of my illuminations




On another forum someone was asking how I got the electricity into the garage, I replied it was connected to the street lighting. Next day he sent me a pm asking if I could supply him with the details of how to connect a cable to the street lights

What I would like to know now is if anyone can tell me where the D3 air-con drains exit and if they are the same orange colour of the D2?

Also where do the D3 sunroof pipes exit?

How big are those drains? They look more like the bulkhead ones to me, though I only know D2 not D3.
On D2 the aircon (condenser tray) drains are not at all large - maybe 1cm - and happen to be bright orange.
