Extra Info:

Symptoms:

Engine runs unevenly
Engine warning light comes on

Extra Tip:

What’s the Issue? Bentleys are built heavy and rely on the brakes. This puts more demand on brake pads and discs, which tend to wear out faster.
How to Spot It:
Your brakes might start squealing or grinding.
You could feel vibrations in the brake pedal.
Stopping the car might take longer than usual.
A brake warning light could show up.
What to Do:
Change your brake pads and discs after every 25,000–35,000 kilometers. This depends on how you drive. Service My Car provides authentic Bentley brake parts and skilled fitting.
A Bit More to Know:
Worn-out brakes reduce safety. Strange noises or vibrations are signs to act fast so schedule a full brake inspection right away.
6. Transmission Issues
The Problem: Bentley owners sometimes notice jerky gear changes or delayed shifts. This often happens because of low transmission fluid or software glitches.
Signs to Watch For:
Gears shift with a delay
Transitions feel rough
A transmission warning light turns on
Gears begin slipping
Service Advice:
Always monitor transmission fluid levels and update your vehicle’s software when needed. Service My Car offers full transmission checks and repairs in both Dubai and Abu Dhabi.
Why It Matters:
Ignoring transmission trouble can lead to total gearbox failure. This repair costs a lot, so taking action can save you money.
7. Oil Leaks
Problem: Older Bentley models or cars driven in intense heat might develop oil leaks because gaskets wear out or seals fail.
Symptoms:
Oil puddles beneath the car
A burning oil odor
Warning light for low oil levels
Blue smoke from the exhaust
Service Tip:
Catching leaks can stop engine damage. Get an underbody inspection done during your next Bentley service appointment with Service My Car.
Additional Insight:
When engine oil runs low, it fails to lubricate . This leads to more wear and possible overheating. Make oil checks and refills a regular habit.
8. Battery Drain Problems
Problem: Bentley cars often face parasitic battery drain because their electronics run non-stop if left parked for a while.
Signs to Watch For:
Battery goes dead after sitting idle a few days
Starting becomes a struggle
Electronic systems stop working right
Maintenance Advice:
To avoid this, use a trickle charger when you’re not driving often and get the electrical system checked for any hidden drains. Service My Car helps find and fix Bentley battery issues .
FYI:
Replace the battery every 3 to 4 years based on how much you drive. High-quality AGM batteries fit Bentley models best.
9. Turbocharger Problems
Issue: Some Bentley V8 and W12 engines use turbochargers. Over time, these turbos might stop working because of issues like oil blockage, lack of lubrication, or overheating.
Common Signs:
Engine makes a whistling noise
Power drops
Extra smoke from the exhaust
Poor gas mileage
Maintenance Advice:
Do oil changes and always pick high-quality synthetic oil. Service My Car offers turbocharger inspections to spot problems and fix them.

The Issue: Bentleys have advanced climate control systems that might stop working because of issues like sensor problems refrigerant leaks, or blower motor faults.
What to Watch For:
Air conditioning not cooling
Controls for climate system not working
Uneven temperatures
Odd sounds coming from vents
