When did BMW E30 3 series air conditioning recharge?
In this technical article I will be focusing on the steps involved in diagnosing, repairing and recharging your air conditioning system on the 1984-92 BMW E30 3 Series.
Why is MY BMW E30 air conditioner not working?
Moisture in the lines is a potential problem, as refrigerant can eventually react with moisture and corrode the insides of the system. The process is completed when the hot liquid refrigerant then exits the receiver drier and passes through the expansion valve. The expansion valve receives the hot liquid refrigerant.
What kind of air conditioner does BMW E36 have?
All of the E36 cars should have R134a-compatible compressors. An E36 conversion kit is available for the early cars that ran R12 instead of R134a (P/N 82-31-9-067-403, about $200). This kit contains a new receiver drier, new O-rings, a capacity label, and a set of R134a valve adapters.
Are there any BMW E30s that are not compatible with R134A?
The E30 cars with compressors that are not compatible with R134a include the 318i (July 1985-August 1985); the 325e, 325i, and 325iC (July 1987-October 1988); the 325iX; and the M3.
When did they add air conditioning to the E30?
Air-conditioning was fitted as an optional extra to all E30s as early as 1984, except the 333i where owners had to choose between aircon and power steering. The system remained largely the same throughout the E30 production run, and is based around a sealed refrigerant oil, just like your fridge at home.
What kind of condenser does an E30 R-12 use?
An E30 R-12 system has a tube and fin type condenser, as most R-12 systems. A parallel flow condenser is required for R-134a because it can dissipate more heat from the higher operating pressure of R-134a due to a more efficient design, ie: more surface area. Below is a pic of the 3 types of condensers used in automotive systems.
