This Mercedes-Benz came in with worn front suspension and an engine oil pump solenoid fault. We diagnosed every issue, gave a full itemised quote, and sorted the suspension, engine electrics, spark plugs, all four fluids and the battery in one visit. Total: $6,200 nett.

The owner brought in the Mercedes-Benz having noticed the ride and handling had become less composed. The car was also showing a fault that needed diagnosing.
The owner wanted a full inspection and a clear itemised quote before any decision was made on what to fix. We lifted the car, scanned it with XENTRY diagnostic tools, and went through everything we found before any work began.
Modern Mercedes-Benz vehicles are sophisticated and comfortable to drive when their suspension and mechanical systems are in good condition. The front suspension design uses independent absorbers and lower control arms that locate the wheel precisely. When these wear, the car loses its composed feel and the tyre contact patch is no longer controlled as the engineers intended.
The engine oil pump solenoid is an electronic valve that controls oil pressure in the engine. When it faults, the engine management system logs a code and, in some conditions, limits engine performance to protect against oil pressure loss.
We connected XENTRY diagnostic tools and pulled every stored fault code. The engine oil pump solenoid fault was logged, along with a wiring fault on the same circuit.
We then lifted the car and inspected the front suspension. The front absorbers had worn past their effective range. The lower control arms and ball joints were worn, and the front linkages had also deteriorated.
We checked the maintenance items too. The spark plugs were overdue. The engine oil, gearbox oil and brake fluid all needed changing. The battery tested below a healthy level.
We wrote up every item with its price before calling the owner to confirm. The total of $6,200 nett was agreed in full before we picked up a single spanner.
A front suspension overhaul involves the absorbers, lower arms and linkages, which all have similar service lives. When one reaches the end of its effective range, the others are usually at a comparable state of wear. It makes more sense to address the full front suspension in one go than to replace items piecemeal.
The oil pump solenoid fault is an electrical component issue, separate from the suspension wear. It is exactly the kind of fault that shows up on a XENTRY scan but would not be obvious without connecting diagnostic tools.
The overdue service items and battery came to light during the same inspection. Catching them all in one visit saved the owner a return trip and kept the car in a healthy overall state.
We completed the full scope of work agreed before we began.
We rescanned with XENTRY after all work was complete. No remaining fault codes.
The total for this job was $6,200 nett, agreed as a full itemised breakdown before work started:
We quote every item before we start. No surprises on the final bill.
Front suspension components have a service life that is affected by both mileage and the quality of roads driven. In Singapore, speed humps and potholes put repeated stress on the absorbers and control arm bushings. Having the suspension inspected at each major service or whenever the ride feel changes is worthwhile.
Engine fault codes that appear and then disappear are often still stored in the ECU. A XENTRY scan at your next service will surface them, even if the warning light is no longer showing.
Engine oil, gearbox oil and brake fluid all degrade over time and with use. Keeping them on schedule prevents the secondary damage that dirty or low fluid causes.
This Mercedes-Benz (Front suspension overhaul, engine oil pump solenoid, spark plugs, engine oil, gearbox oil, brake fluid, battery) was handled at 1 Car Service, an independent workshop in Sin Ming AutoCity, Singapore. For Mercedes-Benz, we use dealer-level XENTRY diagnostics. We hold a 4.9★ rating from 1,775+ Google reviews.
WhatsApp us your Mercedes model and what it is doing. We will scan it with XENTRY, lift it and inspect every fault before quoting. No hard sell, full transparency on costs.
The front suspension on this Mercedes, covering absorbers, lower arms with ball joints, linkages and alignment, was $2,840 including labour. The full job including the engine solenoid, fluids, spark plugs and battery came to $6,200 nett. We quote item by item so you know exactly what you are paying for.
The oil pump solenoid is an electronic valve that manages oil pressure in the engine. It can fail from age, wiring faults or oil contamination. A XENTRY scan will log the fault code even if the warning light has gone out. We replace the solenoid and inspect the associated wiring.
Yes. We use XENTRY, the Mercedes-Benz diagnostic system, to scan the car before and after any repair. This is how we identified the oil pump solenoid fault and confirmed all codes were cleared after the work.
Doing the full front suspension in one visit is more efficient. The absorbers, lower arms and linkages all have similar service lives. Doing alignment once after the full replacement is more accurate and saves a second alignment charge.
We used Mobil 1 on this car, which meets the Mercedes-Benz oil specification. The correct grade depends on the model and year. We confirm this before the oil change.
