Headlight pop up after a day or two

[Uboat]

Hello,

Is everything in order with my +2 when the headlight pops up after a day or to? This never happened before during winter. As soon as the engine starts, the pods go down again.

Is the vacuum system temperature sensitive?

The vacuum system is not temperature sensitive. Popping up after a day or two is not bad but I assume that they stayed down longer previously. You probably have developed a leak and there are many possible sources from the check valve to the slide valve, tubing, actuator and chassis front cross member (which is the vacuum reservoir). There have been several posts on this topic recently. You just have to trace through the whole system to find the leak. When everything is correct on my +2 they stay down all winter (that is not the case right now).
