FAQ:
- Q: How do I know if my fuel pump is failing? A: Symptoms include difficulty starting, sputtering, hesitation during acceleration, reduced fuel economy, and a whining noise from the fuel tank area.
- Q: Can I install a fuel pump myself? A: While possible, it’s a moderately challenging job. Consult a repair manual specific to your 540i model year.
- Q: How much should I expect to pay for a fuel pump for my BMW 540i? A: Prices vary greatly depending on the brand, features, and the type of fuel pump (assembly, module, etc). Expect to pay anywhere from $100 to $500+.
- Q: How long does a fuel pump typically last? A: Generally, a fuel pump will last for 100,000 miles or more but this can vary greatly depending on driving habits and fuel quality.
