Eu am e39 530D si are webasto si am si timer 1 , timer 2 , aux vent insa nu imi apare aux heater, insa imi apare cand e frig afara pre- heating pe bord si iese fum pe sub masina , deci face preincalzire ... are webasto si functioneaza doar pentru preincalzire motor. Ma interesa daca este doar o chestie de soft sa se poata incalzi si habitaclul. UPDATE: Pinched from another forum. Subject: Re: Aux Heater E39 530 diesel Please find a copy of an email I received from Rod Gascoyne the Sales Services Manager for Webasto GB Dear Sir Thank you for your valued enquiry regarding the above. As you are aware, the BMW 5 Series Diesel is fitted with the Webasto Thermo Top C fuel-burning heater as standard, which is used as a supplementary heater. In this application, the Webasto heater only operates when the engine is running and the outside temperature is below 5°C. In conjunction with BMW GB, we have developed a simple upgrade, which includes the addition of a simple electrical interface harness, which will switch the heater on independently. The parked car heater is started by a remote control device and warms the coolant independently from the vehicle's engine. The vehicle's blower system takes the warm air into the cabin and, at the same time, pre-heats the engine. Once this upgrade has been installed, it will provide pre-heating for your vehicle prior to commencing your journey. Some of the benefits associated with such a system are as follows: · Warmth and comfort of a pre-heated interior - a centrally heated interior. · Screen defrost and demist - increase safety with a safer clearer vision through the windscreen at the start of your journey. · Pre-heated engine - no more cold starts/easier starting. · A pre-warmed engine - a better engine response from cold. · Reduced engine wear · Reduced engine emissions - lower emissions from a preheated engine. · "Just drive off straight away and enjoy your journey." The standard installation includes full system integration with the parking heater controlled by a Telestart Remote Control. This allows switching on and off of the system by a remote control handset with a range of 600 metres. In the UK, this accessory is exclusively offered by official BMW Dealerships under the following BMW Part Number: 95.06.0.000.008 or 95.06.0.000.009 (dependent upon model year), therefore you should contact your local BMW Dealer, quoting either of these part numbers in order to obtain the full technical and product support expected within the BMW programme. So, it seems as though all BMW 530D's have one, but it's a BMW part only to get it going remotely. Hmmm, may look into that. Cheers, Gwaredd.
