Ok 2000 1.8 NA Manual Petrol.
Having serious condensation problems inside so investigated today. My rain water channelling plastic covering (the one including the pollen filter covering) is seriously cracked, so obvious point of entry here. This I am going to try glue, but I think I will probably need to replace from a scrap yard.

My battery was sitting in a swimming pool. The two water drain valves (1 under battery and 1 under brake servo unit were clogged; so I poked my finger through them and all the water drained out. They are now just soft rubber holes, should I be worried that there is no "valve" or anything in them?

And Finally, this hose; Where should it be connected? What is it?

Any help with the hose in particular I would be extremely grateful for. Thanks.

 

I just ran into this problem. There are two darwin plugs in the secondary firewall bay. First take the battery out, then take the battery tray out. theres a black rubber plug, pull that out. Its going to have a small shitload of debris in there. Theres another one under the master cylinder. that one is hard to get out so i just shoved a brush in there. And now my problem is solved

I would do this soon as i noticed the water was leaking into my interior via the firewall when these plugs were clogged.

 

So there should be valves in those two holes then? Mine are now empty.

Is the hose in my pictures just a battery vent hose or something else?

 

its not a valve its a rubber grommet filled with dirt, pull it out.

That looks like a battery vent hose in the pic

 

Great stuff mate. So those two water drain holes are empty, just rubber lined holes?

 

theres this weird plug thing with fins or what have you, when u pop it out you will see. it gets clogged. easy fix tho
