Diesel engine repair
Diesel engine repair needs specific diagnosis and care — from the high-pressure injection to the turbo — to keep power and economy.
How we work
Diesel engines have their own traits: high-pressure injection (common rail), turbocharger, glow plugs, after-treatment system and dedicated sensors. We diagnose with a scanner, assess fuel pressure, turbo operation and component condition before recommending the repair.
At Mr. Service we treat diesel with the rigor it demands, avoiding needless swaps of costly parts such as injectors and the pump.
Warning signs
Hard starting (especially cold), excessive smoke, power loss, higher consumption, rough idle, a lit check-engine light or turbo noise all deserve a check.
On a diesel, small injection or intake problems tend to worsen fast. Diagnosing early protects high-cost components.
Why Mr. Service
Correct diagnosis first, a detailed quote before any work and a 3-month warranty on labour. We service diesel engines of every brand, domestic and imported, with service in Portuguese, English and Turkish.
