Hello again guys and thanks for all the help so far.
Was out topping up the oil in my 1999 Passat (which I only own a few weeks) and noticed a big puddle of water under the hood beside the battery and brake fluid reservoir. Surely this can't be normal! It has been parked up for a week until I sort out tax and registration and there has been a few days of rain.
Here are 2 photo's I have taken to show you what I mean...

You can see the dark black where the water is. It is right the way across that top part of the engine, even over where the battery is.
Is this normal, please help!

Hi, no it is not normal.

Here is a post I found on some other forum for the same car:

1999 Passat - Plenum Drain Holes - IDIY
Does anyone know where the drain holes(s) are in the above vehicle ? - I checked the car today and the plenum chamber is flooded (Car Parked on an angle and water 1cm up on electrical ECU box, halfway up the servo !!) The mats inside the car feel dry so fingers crossed no damage to ECU's. I've had a good look with a torch - I haven't removed the battery but I can't see any evidence of drain holes in either corner are they under the battery ?
Thanks in advance

You need to remove the battery & carrier tray to gain access to plenum drain tube.It is a black plastic "rose" about 30mm in diameter,probably blocked with leaves,debris etc.

A million thanks - I removed the battery - not for the faint hearted and found the rose which was blocked. A great bit of design by VW I'm surprised that they don't put plimsoll lines on the components in the plenum chamber - it could become part of the service checklist!! Many thanks once again

Be aware that there are two, equidistant of the centre line. If you know roughly where they are you can clear then with a long screwdriver with no disassembly.

Good luck

You may want to replace the battery while you are at it if you are still on the original. It is kind of a pain to remove.

Thanks guys. As soon as I removed the negative terminal from the battery the alarm went off, didn't know how to disconnect the alarm so re-connected battery. Was able to remove all water tho using a foot pump for an inflatable bed lol. So its off to the pub for a few pints and i'll get my mechanic friend to remove battery tomorrow and clear the hole.
