Check Plenums ! **NEW MEMBERS TAKE NOTE**
 
As above, if you haven't checked the plenum since that last bout of heavy rain across the UK then do so, ASAP.

Despite having had a recent full service by my regular mech - who knows to check the plenum drains - only a month or so ago. I've just found 1/2 an inch of water in the bottom of the plenum. I only checked as every time I've put the A/C on recently I've been getting a slightly off smell for the first 20 to 30 seconds of cold air before it clears, I had wondered weather the pollen filter had gotten damp: it looks like it must have got wet at the bottom. Evidently those last heavy rains had managed to wash some debris down to block the drain and start filling the plenum. I'm glad I checked it now.

The following links to the 'Spyhole mod' how to (I really should get around to doing this).

Maybe another member who know a good link can link to an explanation/how-to for how to check/drain the plenum?

A very good article on the Reason Why you check plenums is shown here and contains photo's of how to do it.

Done yesterday ;) and checked pretty much weekly with the spy mode :)

And that's why I should get around to doing the spyhole mod, as at the moment it's once a month at best (still only takes 15minutes though).

Thanks to the guys who've posted the right links.

Although Ive just ordered a pollen filter as the one in there is a bit pongy lol

This is an ideal tool for doing the job. Mine's always in the boot. Also avalilable from the likes of B&Q, Wilko etc. Cut the twirly bit off the end.

The Plenum Spyhole Mod is a great idea to clear the drains on V6 and Diesel models. The easiest way to check them is to shine a torch along the plenum floor under the brake Servo on the drivers side.

A timely reminder. Yeah, dry as a Pharoahs sock. I didn't do the full mod because the grommet sits a tad awkwardly on the curve of the cover. I drilled a 9mm hole and found it sufficient for the drain unblocker, then put a small piece of tape over it.:shrug:
