w202 diesel start problems
So, I've recently bought a w202 200 diesel from 1995 elegance edition. Very nice and comfortable car, but some problems started to show up.
First of all: Low airflow in the car -> checked the filter which I guess hasn't been replaced for about 10 years, cleaned it out a bit and this helped (I'm in the process of buying a new one).
Second: heater inside the car doesn't seem to follow the rolling buttons which regulate the heater. I have no idea on how to fix this.
Third: flashing buttons in the mirrors, means something is wrong when recognizing the key. However this problem mostly happens when the car has been recently driven. After checking whether all cables would appear to be intact and all connections are still in order my dad and I decided to look at the valve which stops the flow of diesel to the engine when these lights flash. This piece of machinery appears to have diesel on it (so I have a little leak somewhere) also the cables which connect that valve to the IFZ are partially losing their protective cover. So I'm thinking there is a short somewhere there and the diesel is interfering with the signal from the key. IFZ and valve are connected via a CAN bus.
Fourth: The lights behind the middle console don't really work unless a bit of pressure is applied: so a bad contact there.
I would really appreciate input on problem 3, the other ones are minor defects which don't hinder car operation.
UPDATE: we fixed the cables going to the shut off valve, no dice still the flashing lights. Running out of idea's, anybody else got a tip?
