The last few months I made a few modifications.
I retrofitted the OEM PTC heater system. Unfortunately this system was not available for the Dutch market so there were not any used parts at the local scrap yards. After a few evenings bidding on Ebay I acquired the parts for a very low price. My car had some of the wiring already fitted so I only needed to install the wiring between the battery junction box and the PTC heater element.
After installing all needed parts and wiring I activated the system using an ELM327 interface and the ELMconfig software.
The system works very well. The car warms up much quicker than before. When the system is active warm air comes out of the airvents almost immediately.
I fitted a set of black custom heater knobs a few years ago but after fitting the 6CD Sony DAB radio the knobs did not match the radio knob anymore. I decided to remove the black custom knobs and ordered a set of silver custom heater knobs. after fitting these knobs I decided to make a custom knob for the light switch. Now all knobs are the same color and design.
2 weeks ago I retrofitted the Original heated seat system. I removed the seats from the car and installed the heated seat elements to the seats. Originally my seats had allready heated seat elements but the wires were cut off at the factory and the modules were missing. I suppose that during production they were out of seats without heating and installed heated seats with the wiring cut off.
The heated seat wiring was not present on my car so I had to make the wiring myself using the Original connectors. After I fitted all needed parts and connected the wiring in my car the heated seats work great. It took me a lot of time to fit all parts and make the wiring looms but it was worth the effort.
