Hi @RalpherHi, yes I bought the additional door rubbers, the passenger door is fine but the driver's door side required a proper slam to close the darn thing, which clearly isn't ideal for all sorts of reasons.
I spent a long time trying to re-position this rubber but it didn't make any difference.
I'm worried that I might die of old age before finding a satisfactory explanation to this, and boy I have tried.
Firstly, make sure you buy the 3M rubbers (or rather the sticky tape is by 3M) as the cheap stuff is S***.
Secondly, get someone else to install them, that way you can grief them when it does what mine did
I'm going to wait until I'm really bored before attempting the driver side again...
Hope this helps!
Rather than ’die of old age……….’ you may find reading some of the posts since #1 from 2016 useful.
If you don’t have time to read them all, then maybe at least from around #367 to #400 onwards?
The problems/suggestions/answers have been debated over and over, regarding quality, siting etc etc.
The VW Transporter models that come with the extra door seals from the factory actually have different versions of front doors, with holes punched in to allow fitting of OEM seals, which do not come with adhesive tape to affix, but dimples which push into the punched holes.
The R/H front door also comes with an additional air vent in the inner lower rear area to release the build up of air pressure between the inner and outer door seals on closing, which causes the door to ‘bounce’ unless closed very firmly.
Siting of the extra seals and the vent can be viewed at the post #393 by @Loz and earlier some of mine from around #367.
Take a close look at the R/H front door of a California etc which come with these seals, affix your good quality seals exactly as per and then fit the extra vent if door still doesn’t close as required.
This forum contains a huge amount of useful information, but being so big, it can often take a little research to find pertinent answers.
I hope this proves of some use.
