At Squad Workshop, a highly rated specialist car workshop in Singapore, we recently completed a comprehensive repair and servicing package for a BMW 540i G30. This vehicle came in with coolant leakage, ageing suspension components, and overdue maintenance. Our technicians performed a full cooling system overhaul, front lower and upper arms replacement, battery installation, and complete engine servicing.

The BMW 540i G30 uses multiple plastic connectors and hoses that become brittle over time due to heat cycling. Once these components weaken, coolant starts to leak, which can lead to overheating. At Squad Workshop, we recommend replacing the full set of coolant hoses and connectors to prevent repeated failures.
Common signs include:
Coolant loss or puddles under the car
Sweet smell from the engine bay
Temperature warnings
Overheating
Low coolant messages
If you notice these symptoms, it’s best to have the system checked immediately to avoid engine damage.
When one hose fails, it’s usually a sign that the rest are also aging. Replacing everything at once prevents repeat breakdowns and saves on labour costs. It also restores the cooling system to like-new reliability.
A complete overhaul for the BMW 540i G30 typically takes 1 full day, including disassembly, replacement of all hoses and components, system bleeding, and pressure testing.
The front arms contain bushings and ball joints that wear over time, causing:
Vibration
Uneven tyre wear
Poor stability
Noisy steering
Replacing both lower and upper arms restores handling quality and keeps the BMW driving tight and stable.
Yes. Any suspension arm replacement changes the wheel angles. A proper alignment ensures even tyre wear and stable handling. This is included as part of our service package.
BMW’s electrical system is power-hungry due to start-stop, electronic modules, comfort features, and stability systems. A 105Ah battery maintains reliability, smoother starts, and prevents electrical faults.
We use Amsoil European Formula, a high-performance synthetic oil that meets BMW LL-01/LL-04 requirements, paired with an original BMW oil filter for maximum engine protection and performance.
No. Driving with a coolant leak can lead to overheating and catastrophic engine damage. It’s best to stop the vehicle and have it inspected immediately.
