Mercedes-Benz workshop in Singapore

Many Mercedes-Benz models use a brake pad wear sensor. A brake warning can mean the pads have worn down to the sensor, but it can also come from a damaged sensor wire, low brake fluid or a fault elsewhere in the system.

If the warning stays on after new pads, the wear sensor may also need replacing, or the cause may be something else. We inspect pad thickness, check the sensor and wiring, check fluid level and measure the discs. Disc condition should be measured against the specification, not assumed.

On models fitted with air suspension, a car that sits low after parking, a compressor that runs for a long time or a suspension warning can have several possible causes. Possible causes include an air leak from a strut or line, a valve block fault, a tired compressor or a ride-height sensor problem.

We inspect and test the system to find where the air is being lost before recommending a part. Not every Mercedes-Benz has air suspension, so we confirm what your vehicle uses first.

Coolant loss, oil leaks and engine warning lights should be traced to their source. In one Mercedes-Benz E-Class we inspected, coolant and oil concerns had been linked to a possible engine overhaul. Pressure and leakage testing found a leaking intercooler and water pump pipe instead, and the overhaul was not required.

Every vehicle is different, so we test before we conclude. We explain what we find, show you the evidence and recommend the repair that addresses the cause.
