Right grommet for water drain?

Hi guys.

I'm aware that some B5 and B6 A4's had an issue with water under the battery, as do some (B5 too?) Passats. I noticed I had water dripping onto the right hand driveshaft today, and it was consistently dripping for about an hour.

When I shone a torch into the chamber that the battery sits in I noticed about 2" of water. I stuck my hand down the back of the engine underneath the battery and felt a grommet, about 2" in length. I popped it half out to let the water drain, but not all the way out as it would have been difficult to get back in. You can see about a third of this grommet under the battery on the left hand side. The water has now completely drained away.

Question is: are there any proper drain holes in that chamber that are covered up by the battery (other than the one I found), or under the pollen filter etc? I don't want to disturb the pollen filter housing as I know these can be troublesome with water, and I know the battery is a bit of a PITA to get out: so will the removal of that grommet be sufficient for the water to drain away permanently, or do I need to pull all the battery etc out to clear a hole thats been covered up?

Thanks ion advance,
Dan

Lovely jubbly.

Well, as above, I've located the one under the battery, just one to go then. Seems like a stupid design fault to me, but then again I had a Mk4 Golf for 5 years so I'm used to stupid things.

What I think I'm going to do when have the time is remove them, cut holes into them and pop them back so it looks a little more factory. Mind you, no-one will ever go under there so just as easy to leave them out!

Thanks for the help guys.:icon_thumright:
