Hi! I bought a second-hand 156 from 2000 with the 2.0l TS engine. (I’ve already opened a Tread for a lot of anticipation…) Since this morning I have the car now in my fingers. 1.) I found out after some time that the air conditioning is not running (outside temperature approx. 8 degrees). But during the test drive it was running, I’m actually sure. I heard a hissing from the ventilation grid, which disappeared after a short time when I switched off the climate. I can’t hear the magnetic coupling when switching on. Can it be a fuse? What else is there for reasons? 2.) I have a red light on the amature board. It probably comes from the alarm system. It lights up permanently. At Fiat, you didn’t even know what the lamp was, d I thought it was a game game from the previous owner (the car was a test vehicle before). In the manual I have now discovered that it is a malfunction in self-diagnosis when sharpening the system. Now the questions: – Can you read the errors via ODB? – Where are the interior sensors? In the manual it says that it is optional to have these. I would like to know if I have any… -How can I get my Diva back so that they look after themselves again. nn? – How much does the emergency key belonging to the alarm system cost? Did not know that there is such a thing when buying a car. And now I have seen that there is still a “Zündschloss” in the fuse box. I would be happy if there is someone here who knows the Alfas well, because the Alfa workshop (in Aachen) does not seem to be so wired with their own vehicles. (I also had a vehicle check made before the purchase to find out if the car is good. notice the broken carrying joint at the front left, which shakes from the pure touch…)
