New water feature

[apole]

Suffered a common problem today with the heavy rain. Car full of water on passenger side, even on top of the mats.

Apparantly this is common and something to do with a drain hose near the pollen filter/battery.

Anyone experienced this, is the part easy to get at and change?

What a nice end to the day

If it's something that can be checked, I'd advise people to check occasionally as the amount of water in there is unreal. Hope it doesn't damage anything till I can get it seen to.

Been doing some research on this as the likely cost of repair could be quite high, not only to remove and dry the carpets, but also the convenience ECU is located in the passenger area and if that gets wet, it will cost big bucks.

There are 2 reasons the water can get in, firstly around the pollen filter, for which there is a fix, and also the drain holes under the battery get blocked, for this you need to check them.

Posts below but well worth checking out, when you get this problem you will regret it....

Hope it helps.

Common problem with passat (3B) The pollen filter housing seal perishes and allows water in to the passenger side footwell. The wiring conectors/terminals become damaged and corroded often causing alarm faults ( false alarms etc).
Terminals to be renewed and the convienence control unit also.
The carpet and underlay will need to be dried out or renewed. Light colours will stain, beige or grey. Black carpets are usually ok.
Sometimes get a nasty whif that remains even when dry! break out the febreeze and it should go!.

Main dealer will charge about 8-9 hours plus £200 parts (without the carpet being renewed).

Hope this helps.

Ive just dug my ccm out of the passenger footwell and to put it bluntly its goosed it had pins missing in the sockets and the plugs were corroded to hell phoned vag to source replacement plugs and loom and guess what they dont do them they make their own up and i will have to take it down to them to have the job done (open cheque).Does anybody know if you buy a second hand one can you programme it from the key fob or is it a main dealer job?

[greas-E-monkey]

Programming is done using the 5051 vag computer so I am afraid it is a main dealer job. The pins/terminals are available to buy from VW but you would need to know the sizes etc to be able to order them to part number. (they can do this you cannot!). I am afraid they have you by the balls so to speak.

Thanks for the advice ive managed to source a second hand ccm complete with 18" of loom and the two plugs exact same part number and in pristine condition for £89.00 with a 3 mnth guarantee,just wondering if i can still use the car before it gets reprogrammed by vag and if i can what functions will be lost ie central locking etc. Regards Ed

Hi, whatever the dealer can do with their diagnostic equipment can be done with a 30 pounds vag-com interface and an old laptop ! See www.openobd.com for more info about how to code CCM modules and www.tdiclub.com for more advice. I am against dealers who charge enormous amounts of money for some of their services but sometimes its easyer to go that way + may be less frustrating but, if you do your research and are handy with the laptop, sky is the limit ! I would advice you get ELSA WIN (do a ebay search !) as its contains reference tables and workshop manuals for every vag car(actually is the program dealer techs use on their computers), not easy to use but you'll get the hang of it ! As for water ingress on the passenger footwels, clean the drains under the battery and polen filter housing. Common guys, get your hands dirty and when you done crack open a few beers and buy a bunch of flowers for the missus to keep her quiet !!! Good luck.

so where is the pollen filter. i have opened the bonnet and cleaned the air filter. is it under the battery or under the mysterious balck box om the left at the back. non technical terms please.

[adamss24]

The polen filter its on the passenger side under the windscreen. You may have to remove the plastic trim to gain access to it ! The drain holes are under the battery and under the ECU on the driver side.
