Check engine light
Diagnostics for an engine warning light, including stored faults and the systems related to the symptoms you have noticed.
Diagnostics
Car losing power or in limp mode
Diagnostics for changes in acceleration, engine response or reduced-power warnings, based on the symptoms and recorded faults.
Power loss can be gradual, so you only notice it on an overtake, or sudden, with a warning and limp mode. Either way, the engine is protecting itself from a fault.
Common causes
- Boost leaks or turbocharger faults
- Clogged air, fuel or particulate filters
- Misfires from coils or plugs
- Gearbox faults that limit torque
Diagnosis
We read live data on a road test and compare it with the manufacturer’s values, so the repair fixes the cause, not the symptom.
Questions and answers
What is limp mode?
A protective mode that limits power and gears when the car detects a serious fault. It lets you drive slowly to a garage.
Can poor fuel cause a loss of power?
It can, but it is rare in the UAE. Clogged filters, boost leaks and sensor faults are far more common.
