Hi!
I bought a 2003 Golf 4 TDI 74kW PD model Pacific 3 weeks ago.
I learned from the previous owner that the car was involved in a minor accident on the left side.
Now, after 3 weeks, I'm seeing some defects that I want to fix!
First, I had to replace the generator regulator because it wasn't working.
1. The middle LCD on the KI is difficult to read despite the KI's good blue lighting.
The LCD lighting is intermittent, sometimes good and sometimes better. I think it's due to the light sensor under the speed needle. When I shine a flashlight on it, the LCD becomes brighter, and it becomes darker when I remove the flashlight.
I have also noticed that a blue wire is connected to terminal 12 (for the generator) on the blue connector of the KI unit, (I suspect that the previous owner tried to hide this error using this method). However, I still need to check where this cable is connected.
The display looks like this:
Then I also have problems with the fuel level sensor (the display on the dashboard is not correct). I have noticed that the float has fallen from the fuel pump housing into the tank. After repair, it is not much better. After a full tank and about 200 km later, the pointer is still at full. (it also took about 20 minutes for it to go from 0 to full).
P.S. maybe the KI is defective?
P.S. I am from Slovenia and apologize for my spelling mistakes!
