An oil leak, misfire or temperature warning needs a cause identified before an engine repair is quoted. Digi-Tec assesses Mercedes engine and mechanical concerns at our Al Quoz workshop, using the vehicle details, service history and test findings to agree the next step.

Independent Mercedes workshop in Al Quoz · Established 2002 · XENTRY/Star diagnosis where compatible
Vehicle-specific scope
Tell us when the change happens: cold start, warm idle, acceleration, traffic or after parking. That context helps separate an engine-running fault from transmission, mount or driveline vibration.
Record whether it happens while stationary, in gear or only at road speed. Ignition, fuel delivery, air leaks, compression and mount condition are different test paths; shaking alone does not establish which part needs work.
Warning lights and engine-running symptomsNote the colour, duration, smell and whether oil or coolant is being lost. Brief condensation and persistent smoke need different assessment. Smoke colour alone cannot confirm a head-gasket, turbocharger or internal-engine fault.
Leak tracing and cooling-system tests establish the source before a hose, pump, thermostat or internal repair is proposed. A temperature warning needs prompt attention; do not open a hot cooling system.
Overheating: stop and assessment guidanceAir/boost leaks, fuel or ignition faults, exhaust restrictions and control problems can feel similar. Diagnostic evidence comes first; turbo or engine repairs follow only if the fault is confirmed.
XENTRY diagnosis for reduced powerIdentify the fluid, source and spread of the leak. Oil on an undertray or a photograph of a wet engine cannot establish which seal or component failed.
How an oil leak is investigatedThe inspection checks when a noise or movement occurs and which assembly it follows. Parts compatibility, access and any further dismantling are explained before the repair is authorised.
Share the VIN, model year, mileage, warning text and previous repairs. Engine family alone does not establish the fitted components or repair procedure.
Inspection may include leak tracing, cooling-system checks, compatible fault data and mechanical tests where indicated. A stored code is evidence to investigate, not an instruction to replace a part.
The estimate separates diagnosis, accessible component repairs and any further dismantling needed. Internal repair or replacement is considered only when findings support it; additional investigation requires agreement.
Verification is matched to the job: leak checks, operating temperature, fault review and running or road checks when appropriate. Remaining findings are discussed at handover.
The quote identifies the proposed parts option, seals, fluids, labour and any additional diagnostic work. Engine oil approval, coolant and component compatibility are checked for the exact vehicle. Availability and completion time are confirmed after inspection.
Request a Mercedes Engine InspectionModel and owner guides
Explore the relevant symptom, model or service scope to help describe the concern when you contact the workshop.
For an oil leak, coolant loss, rough idle or unusual engine noise, record whether it happens at cold start, warm idle or under load. Note changes in oil or coolant level and any recent repair. A warning, photograph or smoke colour helps describe the concern but cannot establish an internal-engine or turbocharger failure.
Confirm the initial assessment scope and its cost before work starts. A repair decision may need further tests or dismantling, discussed first. The repair estimate identifies findings, parts, fluids, labour, supported procedures and relevant completion checks. Additional work needs approval; timing depends on the agreed scope and parts availability.
