What are the Most Common Problems with the BMW G30?
Despite its solid reputation and long-term durability, G30 also runs into some issues and problems over the years and needs special attention in maintenance for smooth running. The common problems with BMW G30 are AC issues, fuel pump problems, faulty water pump, timing chain issues, and sunroof seals.
These problems, although common, occur only after 125,000 miles or if the car is not maintained properly.
1- AC Issues
The main issue with the air conditioning system in G30 is the alternating fan speed, and faulty condenser or cooling coil. Owners report the fan switching speed on its own and losing the cooling power over time. This problem is common in this generation and usually occurs after 125,000 miles.
2- Fuel Pump Problems
The fuel pump in G30 5 series is known to be fragile and gets clogged or damaged, usually due to poor fuel quality, as it is expensive to replace. The seals and connections are known to fail over time and cause problems with engine performance. This issue usually appears after 150,000 miles of running.
3- Faulty Water Pump
A faulty water pump is a common problem faced by G30 owners, causing the radiator system to fail completely. This leads to frequent overheating and fatal damage as the engine is not fixed timely. It usually occurs after 150,000 miles and is usually due to negligence in radiator servicing.
4- Timing Chain Issues
Another weak spot in the BMW G30 is the timing chains, that although quite robust, are known to span out of nowhere, rendering the car motionless and useless. This problem can appear as early as 70,000 miles, and replacing the chain timely can avoid this issue.
