Thanks guys,
I have only just got back to the lap top so cant check till tomorrow now, but these tips sound great the photos and how to by (majesticlarge) are great, I think it would be a lot wetter in the front foot-well if that was causing the problem but I think its a great tip for anyone with an Omega just to check now and then as part of your routine maintenance. I will start at this point but the Door membrane sounds like it is the cause if the door drains are blocked so I am hoping that this will stop the problem.
The front well did get a little water but I think it had flowed over from the back once the rear foot-well was up to about five inches deep it runs over the hump where the front seat is fixed. Well wish me luck and I will report back once I have checked everthing out tomorrow.
Thanks again everyone much appreciated.
