Hello, our Arto has just sailed through it’s annual service - not bad for nearly 20 years old! The only thing mentioned was one LED missing from the high level break light. There are heavy showers today and i noticed a patch appear underneath the driver’s window - rain had been pouring off the roof and channelled by the awning toward this front corner, but I don’t recall having seen this before. The outside seals are in good condition - does anyone know why this patch has appeared and what I could do about it…
