Over 300,000 Volkswagen Golf Mk7 manufactured until June 2013 may have a problem with the Air Conditioner drainage hose being installed incorrectly which leads to water accumulating in the passenger foot-well. As of September 2013 only around 50 cases of this occurring have been identified.
Condensation that collects on the evaporator is normally discharged to the outside via a small hose on the firewall.
This problem also affects the Audi A3 and Seat Leon.
After upgrading the RNS 510 to a higher version of firmware (3810 or higher) from revision C or earlier hardware running software 2840 or earlier the backlight may stop working after the gateway update and subsequent reboot. The screen can still be viewed with some additional light.
This recovery cd is based on the 2760 firmware but can be used to recover RNS 510’s running any version. Insert the media into the RNS 510 and start a new SWL process by pressing Setup + Eject +Info/Mic (top right hand button next to the DVD slot). It will attempt to restore a new SWL process and will enable it to boot up. There may be a problem with the RVC not working after this however and if this occurs and you want that to remain working you will need to flash an older version.
The Volkswagen RVC Camera from the Mark VI has a drain hole under the camera in the housing and this does build up a substantial amount of water under the right circumstances, I found around a litre of water in the base of the hatch after a downpour and when the hatch was opened in ran down inside the area around the rear window. There are two problems with drainage into the rear hatch and one is that many Golfs have all three drainage holes plugged and painted over and the other is that not all water can drain but instead sits in the seam at the bottom of the hatch until the rear hatch is opened.

I removed one of the drainage plugs in the middle and whilst it stopped the buildup of excess water I had concerns about the rear hatch long term especially when so much water can make it’s way inside the hatch. The Mark VI has a tube that drains to the outside and that’s what I’ve done here.

Fitting the tube
After the drain plug has been removed push the tube in.
The tube fits in under the lip on the bottom of the hatch so will require some jiggling around to force it under.
Connect the clear tube to the drain above it.

Adjusting the operation of the RegenLichtSens (RainLightSensor) is possible through Vagcom/VCDS or the VAS tools that Volkswagen dealers use however adjustments do not make a large difference in the operation of the sensor especially where you have the standard green glass.
Using Vagcom/VCDS open controller 9
Select the dropdown box and select option 2
Select config helper (may require version 10 of VCDS)
A common source of noise (rattling, clicking and squeaking) is the rear seat latches, when the seats move the lock mechanism moves around on the latch and makes a noise. You could try tapping them with a hammer from above to bend the latch slightly downwards but this doesn’t seem to fix the problem in most cases.
To test to see if it is the latches making the noise drive around with the seats lowered. If it is the latches the simplest fix is to wrap some electrical tape around the latch where the lock contacts it to stop the movement and remove the metal on metal noises. The fix should last for around 50 operations of the rear seats before you have to reapply the tape and only takes a few minutes and a roll of electrical tape (3M Temflex 1610 was used but any quality brand is ok, avoid cheap brands) in any colour except for body colour or black as you won’t be able to see if parts of the tape are stuck in the mechanism or if the tape requires replacing.
Lower the rear seats
Clean the latch with a suitable cleaner (99.7% Isopropyl alcohol or similar is suitable)
Wrap 14cms of 3M Temflex 1610 electrical tape (or equivalent) which will give you six full wraps.
Close the rear seat
(the latches after cleaning, you can see where the lock mechanism has been contacting on the first photo)
(the latches after applying the tape, this is the area in which the lock mechanism contacts the latch)
(this is the tape after many uses, it should be replaced before it looks like this – I had started to peel it back prior to the photos)
(check the lock mechanism for any large stray pieces of tape that might cause problems with the operation)
The PXE16 has a minimum displacement of 4.9cc, a maximum displacement of 163cc, maximum speed of 8500RPM and 7 pistons. The displacement control is external and varies the compressor displacement without the use of an electromagnetic clutch. The unit runs all the time and varies output from 2% through to 100% as required.
Refrigerant used is R-134A and the oil used is SP-10.
