Thanks for the advice. Looks like I should remove the panel. I just thought things were best left undisturbed if possible.

I got mine check by the amazing Mr Nick at Austin Garages. He even did a cool cheap mod - cut the drainage tube a bit! The tube gets thinner so easily blocked. Cut the tube before the thinner section and you should be safer.

Takes 5 seconds to slide the panel out without removing or breaking the skuttle panel !!!

I have cleared the blockage in the so called plenum (for which thanks to various posts on how to do that). However it sounds as if I must have blockage to the sunroof drain(s) for water to end up in just one rear footwell. I think the other 3 footwells are dry. Can anyone point me in the right direction for instructions on how to clear the sunroof drain tubes?

Hi Simon.
Have a good read Arctic

Thanks your reply. This implies the problem is solved by clearing the tube running down behind the fuse box. Before I embark on this, there does not seem to be water in the front on-side foot well. Is it possible that there is another tube leaking direct to the area of the aft footwell? As I understand it there are 4 drainage holes from the sunroof of which that is presumably only one?

Appreciate your guidance!

Arctic has documented the rear drains starting at post #27 in that thread http://www.the75andztclub.co.uk/foru...+solved&page=3 There are four drain tubes in all one in each corner of the sunroof.

It's a job that i need to do before mine succumbs to the wet carpet scenario

Does the plenum issue affect MKII's. I thought the facelifted 75 and ZT had redesigned drain holes etc.

Hi Del.
All R75 & MG ZT have the same issues and need checking regular in my opinion Arctic

As Arctic says all are still prone to the dreaded blockage by crumbling leaf, I have rodded many for members who never knew there was a drain there! Several options for reducing risk of blockage include cutting off end of plenum drain at a angle to improve drainage, you can buy a guard from Jules to stop leaves etc entering on drivers side though on mark twos no drain on drivers side. My preferred option is to use the aquatic foam used in fish tanks shaped by cutting to size of gaps each end of the scuttle, the holes are large enough to allow water to drain freely but block all leaves and other debris twigs etc, since I did mine 18 months ago plenum chamber has been clean and no blockages. Hope you find this useful
