You've got me worried now. I. check clean or rod the passenger plenum tube out weekly but I never touch the drivers side one as its not very accessible. Will this cause flooding problems in the plenum chamber or will the water simple drain through the passenger tube instead.

Hi Johnny
As long as the passenger side is free of rubbish and as good outlet ie the flaps been cut of at an angle 45 degrees then in my opinion all should be ok, but merely looking into the plenum chamber from the drivers side with a torch and seeing it is clear, will not be enough what if the tube as only just blocked up and it pours down all night and for a few days, this is why it is best to do the spy hole mod, then check at least once a week if not more in really bad weather only takes 5 minutes.

Afternoon chaps
Get yourselves some netting or filter sponge and stop the debris getting into the bulkhead in the first place.........then it's just yearly checks from then on.
Every 3 months I pour a bucket of water over the driver's side windscreen area and watch it drain from 4 places underneath ! Or 3 places for later cars with only 3 drains
(rear of both arch liners and right and left sides of the rear edge of the undertray)

Delux solution
Why worry every week when you can fit and forget one of these.

Thankyou both for putting my mind at rest. I've done the spyhole mod a few weeks back and as you say, it takes 2 mins to check to plenum drain making it so much less hasel of a job. . The previous owner has cut the tube as when I peer down the spyhole I can see straight through the drain tube at the road below. Next mod will be Jules filter to stop all the rubbish getting there in the first place
Many thanks
John

Cheers for this.
Just checked mine and sure enough, 2 inches of water.

Cleaned out, and now on the regular check list.

My plenum was clear under the ecu but still found water was pooling up on the drivers side as the drain under the servo was blocked. Maybe the car was parked at a slight angle but the water drains away from the plenum a lot better now that I have cleared the one under the brake servo. I would recommend doing it, I managed to do it from above.

Saved your ecu but probably have water under your carpet
