Thank you, ***** ***** is helpful. I assume the seal fails because it is rubber and therefore perishes with age and use ?
After I'd had the PSE replaced (to fix my car's central locking problem that I needed resolved in a hurry as I was going away on holiday so needed convenient access to the fuel filler cap) I was quoted - by a dealer - £2000 and being without the car for 6 days for "replacing the boot seal". [I won't identify which dealer unless you ask !]. That seems somewhat excessive compared to your mention of £300-£350. I do recognise the advantages of a dealer repair (especially as you mention the need for particular tools and equipment). Can you suggest to where I might take the car for a repair at or nearer the cost level you have mentioned ?
Are there any drain holes I should be aware of (other than the ones at the left and right hand side of the boot just behind where it joins the rear screen) ? I've taken care to keep these two unblocked, but I'd like to ensure any others are treated similarly.
I live in NW London ... but I'm mobile (at least, for the time being). Where are you ? For a reason that must be obvious, I don't mind travelling for a repair (or so that the car and its actual seal can be examined). I do try to remove algae, moss and other detritus as I really like the car and want it to last a few years yet. By the way, the aforementioned dealer said that my Tier 1 MB Warranty (for which I pay, having had the 2007 car for 3 years myself) doesn't cover seals: I'm not 100% convinced they're right about this when I read the policy document; but you know the purpose of ALL Insurance is to take your premiums then niggle over the small print when it comes to paying out so they might be right.
Thanks for the website link, Paul.
Sturry is only about a*****away from where I live (via M25), so that wouldn't be a problem and I presume I could get a train home if I needed to and decided to leave the car with you after an initial inspection (or return another day having booked it in). I fully realise that your role on the justanswer website is unrelated to your "day time job" so rest assured discretion also wouldn't be a problem. There are potentially advantages to both of us (&/or your employer) if a repair can be carried out under Tier 1 Warranty. I have a £250 excess so know I'd have to pay that personally. If you ARE able to check with your warranty administrator in advance that would be helpful - even if I have to wait a week or so.
I'm reluctant to pull too hard on the seal in case I break it or detach it - then I'd really be screwed as the car isn't garaged, it's street parked, but I'll give it a gentle examination tomorrow in the daylight.
I'll be away from my computer for the rest of the evening, but will get back to you tomorrow whenever you respond. Rod
