Hi
just bought a golf 5 1.4 tsi few months back for quite cheap. Had a few issues, fixed most of them but i'm still scratching my head because of the check engine light.
It gives me the following fault code:
- P2185 engine coolant temperature sensor 2 - circuit high
The fan still powers on and cools the engine down but not when the AC is on. That might be why my AC isn't working atm.
First thing I did was check the wiring and noticed some very dodgy wiring at the sensor. Did some wire work and replaced the sensor thinking that would make the dtc go away but no it keeps coming back.
Next thing I did was compare with another golf 5 of a colleague of mine because i'm not familiar with vw. Noticed a relay between the wiring on mine while the other golf had none (see picture). I don't know why it was placed there.
Car drives fine though and fan works.
Wondering if this could cause the dtc and how should I continue from here. Any help appreciated.
