What are the Most Common Problems with the BMW E36?
Although BMW E36 is a sturdy vehicle, it also suffers from problems over time due to negligence or poor maintenance. The most common problems include a faulty water pump, VANOS problems, rough idling, engine oil burning, and radiator leakage.
All of these problems tend to show up after 100,000 miles or so;
1- Faulty Water Pump
This problem occurs due to a plastic impeller that regulates the water movement from the radiator to the engine. It is known to crack or get damaged over time due to fragility and can cause frequent engine overheating. It usually occurs after 120,000 miles.
2- VANOS problems
This is a notorious problem with E36 and is also known as “Vanos Rattle”. It occurs due to Vanos-seal failure and a faulty piston bearing. It can be prevented by timely inspection of the engine, as it is costly to repair and occurs after 100,000 miles.
3- Rough idling
If the idle control valve gets chocked due to debris or the DME compartment gets flooded with water because of a poor seal, rough idling occurs on an E36. It is also a common issue and tends to occur after 150,000 miles.
4- Engine oil burning
The main culprit behind this problem is a faulty cam cover gasket, which leaks oil and causes burning if it gets in contact with the spark plug. Its solution is also a timely replacement, and owners must be careful about it after 125,000 miles.
5- Radiator leakage
This problem occurs due to the fragility of parts used in the assembly. The plastic thermostat housing and the top radiator pipe crack over time and the radiator leaks the coolant. This leads to overheating of the engine and can be fatal for the car. This problem occurs after 100,000 miles.
Cost of Fixing the Common Problems with the BMW E36
| Fault | Cost | |
| 1 | Faulty water pump | $800 |
| 2 | VANOS problems | $750-900 |
| 3 | Rough idling | $400-600 |
| 4 | Engine oil burning | $500-700 |
| 5 | Radiator leakage | $500 |
