Hello people, I have been looking for light machines at ebay and found you somewhat uncertain about the many light machines. I asked myself at vw which light machines I need exactly….Answer…. 07c903018x …..but now I have found another 3021G in the end has instead of 3018X which is also a lot cheaper. Has someone made the experience with it whether this model of the light machine with the 3021G also fits my Pheaton. Thanks in advance ??
