This is a common fault on Vaillants with the turret seal perishing. Its noticeable when you see the crusting around the top of the main heat exchanger and means there's products of combustion spilling into the boiler.

I always keep a few of these seals along with the flue seals as it's a case of either shutting the boiler down or fixing it on the spot to keep your customer going with heating and hot water.
