This BMI kit is Compatible with: Passat (sedan and wagon) with TDI engines built from 2012 thru the 2014 model year (automatic trans only) This kit was developed because people were tired of cold mornings with rough starting and no heat for 10 miles, and no other such heating system existed. BMI Heater Kit Details: The 1000 Watt tank heater circulates coolant throughout the engine for QUICKER STARTS AND INSTANT HEAT! (TDI owners know how long it takes to get heat!) Benefits include: reducing wear on the glow plugs, starter and battery. Oil pan heaters only heat the oil, and could be a fire hazard. Without any accessible freezeplugs on the engine, a freezeplug heater is not an option either. Compact in size, comes pre-assembled with all necessary parts, hoses, and mounting bracket. The kit fits like a glove, and has good clearance around the heater even when installing the unit. It will have a factory appearance when installed.
