Engines: 1.0 T-GDi (48V) (Hybrid) · 1.6 T-GDi N (Petrol)

Carbon on the injectors and intake of the T-GDi petrol enginesInjection / turbo
Engine / equipment
Hyundai and Kia 1.0 and 1.6 T-GDi direct-injection turbo petrol engines
Period mentioned
2015 onwards
Symptoms
Loss of power, higher consumption, hesitation or rough idle, usually at high mileage.
Possible cause described
With direct injection, petrol does not wash the intake valves and carbon builds up on the injectors and intake. German guides mention it for the i20 III, Tucson IV and Picanto III (dirty injectors).
Check for the garage
Read misfire and fuel-trim codes; inspect the injectors and valves with a borescope; clean the intake if there are deposits.
