Hyundai Tucson Exhaust System: Specs, Fitment & Common Faults

A genuinely important distinction: hybrid Tucsons use a different filter entirely (a PPF, not a diesel DPF) requiring different methodology — plus an honest, frustrating account of a dealer dismissing visible evidence three times.

OEM Part Number: confirm via VIN — Rear silencer (aftermarket) Bosal 165-287 / Walker 24045

Accuracy note: Covers the Hyundai Tucson (2015-2020) as listed in the UK aftermarket catalogues. Exhaust part numbers depend on engine, fuel, emissions standard (Euro 5 / Euro 6) and body — the catalogue listings below are aftermarket references for this generation and are not engine-filtered, so confirm the fit by your VIN or engine code before ordering. Walker 'code letter' values (52, 62, 91 etc.) must match the system fitted. Genuine numbers are only shown where a listing quotes one.

A Genuinely Important Distinction Worth Knowing If You Have a Hybrid — Hyundai Tucson Exhaust System

If your Tucson is a hybrid rather than a diesel, this is genuinely worth knowing before applying diesel-specific DPF advice to your car: hybrid Tucsons use a different filter entirely, called a Petrol Particulate Filter (PPF), since the engine is petrol-based despite the hybrid system. A warning light referencing this filter requires a genuinely different methodology to clear than the diesel DPF light, and advice aimed at diesel owners doesn't necessarily transfer directly. If you're seeing a particulate filter warning, it's worth confirming with a dealer specifically which filter type your car actually has before following generic DPF troubleshooting advice found online.

A genuinely honest, real account worth knowing about before accepting a dismissive diagnosis: one documented case saw a Santa Fe diesel with a visibly sooty boot and black-stained exhaust pipes taken to the dealer three separate times, each time being told no faults were recorded and the car was within acceptable limits for an MOT. If you're seeing clear physical evidence of a genuine issue — visible soot, staining, or unusual smoke — despite a diagnostic scan showing no fault codes, it's genuinely worth pushing back and requesting a more thorough physical inspection rather than accepting a scan result alone as the final word, since a computer diagnosis can miss issues that are visually obvious.

It's also worth knowing about a genuinely specific, distinctive diagnostic pattern documented on related diesel models: hesitation occurring specifically when the engine is warm rather than cold, at a fairly consistent RPM around 1800, with the problem notably easing when the air conditioning is switched on, has been linked to EGR-related issues. If your symptoms match this exact pattern — warm-only, a specific RPM range, and improvement with AC on — it's worth mentioning this precise combination to whoever is diagnosing the car, since it's a genuinely distinctive enough pattern to help narrow down the cause.

Hyundai Tucson Exhaust System: The Part That Announces Its Own Problems

On the Hyundai Tucson, most faults are things you'd spot visually first, but this one usually announces itself acoustically — a rattle, a drone, a noticeable jump in noise levels. That's actually helpful, since it means you'll likely notice trouble well before it gets serious.

Before you buy: exhaust configuration differs significantly by engine size, fuel type and whether your car has a particulate filter. Always confirm against your VIN before ordering.

Hyundai Tucson Exhaust System: What It Does

Three jobs happen inside the Hyundai Tucson's exhaust system: routing burnt gases away from the engine, quieting them through the silencer, and treating emissions via a catalytic converter and particulate filter. Petrol and diesel variants often need completely different systems to meet their respective emissions requirements.
