The brief
The B180 came in for its service, the owner keeping it on schedule. That's the right habit, a service isn't just an oil change, it's the multi-point inspection where a workshop goes over the whole car and catches the small stuff before it becomes the expensive stuff, the things you don't see until someone's underneath looking for them. A proper service runs through the lot: change the engine oil and filter, replace the air and cabin filters, check and top the fluids, look over the brakes, suspension, steering and electrical side, test the battery under load, run a full diagnostic scan, and eyeball the belts, hoses and underbody. Anything found gets reported and sorted. Done on time, it's the cheapest insurance there is.
The diagnosis
The multi-point inspection went through everything. The engine oil and filter were due, the air and cabin filters near the end of their life, and a couple of fluids wanting topping. The brakes had healthy pad and disc life left, the belts, hoses and underbody checked out clean, the battery tested fine on load, and no fault codes were stored. So it was a straight service: replace the wear items, freshen the fluids, scan it clean, and hand it back.
The work
The engine oil was drained and refilled with the correct Mercedes-spec oil and a new oil filter fitted. The air and cabin filters were replaced, the fluids topped to spec, the brakes cleaned and adjusted, and a full diagnostic scan run with no codes left stored. The belts, hoses, suspension and underbody were checked over and the tyres set to the right pressures. A quick run confirmed a clean start, steady running, and nothing leaking.
The outcome
A clean bill of health on the B180, fresh oil and filters, fluids topped, brakes checked, and a clean diagnostic scan. Back on the road for another interval. The car went home serviced properly. A service done on time is what keeps a car reliable, and the multi-point inspection that comes with it is what catches the small problems while they're still small.
