Pre-heating

Hello

I changed glasses on my headlights today. Under that a tube fell on which is so blind in the area. It then leads under the auxiliary heating. What kind of guy is that!?

Besides, I can't use my heater. If I turn it on, the blower will start, but there's no mux coming from the preheating. Where do I start looking?

A few months ago, there were problems. Something with flame out or something when reading out.

At present, however, there is no error in the error memory...
