A Genuinely Honest, Real Account Worth Knowing About Before Accepting a Dismissive Diagnosis — Hyundai i30 Exhaust System
This is genuinely worth knowing if you're facing a dismissive response to visible evidence of a genuine exhaust or DPF issue: one documented case on a related diesel Hyundai model saw a visibly sooty boot and black-stained exhaust pipes dismissed by the dealer three separate times, each time being told no faults were recorded and the car was within acceptable limits. If you're seeing clear physical evidence of an issue despite a diagnostic scan showing no fault codes, it's genuinely worth pushing back and requesting a more thorough physical inspection.
It's also worth knowing that hesitation occurring specifically when the engine is warm rather than cold, at a fairly consistent RPM, with the problem easing when the air conditioning is switched on, has been linked to EGR-related issues on related diesel models.

Hyundai i30 Exhaust System: What It Does

Petrol and diesel variants often need completely different systems to meet their respective emissions requirements.
