Update for any interested UK Eos owners who still have leak issues. My Eos (delivered 13 January) still has an occasional drip onto the interior sill as I described in an earlier post. It seems to be completely random - heavy rain can leave it bone dry but then after a wash the drip can appear.
The car has been to the nearest dealer with an Eos trained technician and "recall 61A8" was apparently carried out, the car was water tested (not sure how) and declared to be leak free.
When the drip re-appeared a few days ago I e-mailed the salesman with a copy of Michael's post attached. I have been contacted by the Service Manager who advised that they believed that the dealer who carried out the previous work had lubricated some of the seals (no mention was made of the VW lubricant so it may or may not have been that which was used but I would hope so). He said the special lubricant was on back order (ie out of stock) as there was none in the UK at the moment(!) and it would arrive in 7 to 10 days. When it arrives, the car will be booked in and they (the supplying dealer) will carry out a full lubrication.
I will update you all as to the results as soon as I can. I sincerely hope they do the work as thoroughly as Michael and his dealership and achieve the same results!!
