SsangYong Rexton: DPF Clogging on Short Urban Trips

DPF Clogging on Short Urban Trips is a common engine fault on the SsangYong Rexton on the 2018 onward cars, and we rate it major. Putting it right costs $350 to $4,200 at New Zealand independent workshop rates. Below is what goes wrong, the symptoms to notice on a test drive, where to look, and what to ask the seller before you hand over any money. It is one of 13 documented faults on the SsangYong Rexton.

What you are looking at

No photograph available

We do not hold a verified photograph of the Diesel particulate filter yet. We would rather show none than show a picture of a different part.

What goes wrong

The diesel particulate filter on the 2.2 D22DTF engine requires sustained highway driving above 2000 rpm to complete passive soot regeneration. Vehicles used primarily for short urban trips never reach the exhaust gas temperature threshold needed to burn off accumulated soot, causing progressive DPF blockage. A forced regeneration performed by a dealer clears the blockage, but heavily blocked units that have exceeded maximum ash loading require full DPF replacement.

What you would notice

  • DPF warning light illuminated on dashboard
  • Reduced engine power or activation of limp mode
  • Increased fuel consumption as ECU attempts regeneration cycles
  • Excessive black or white smoke from exhaust during regeneration
  • P2002 fault code indicating DPF efficiency below threshold

How to check it

Where to look. Exhaust system, underbody behind catalytic converter

  1. Scan the ECU for DPF soot load percentage and ash load percentage — above 80% soot requires immediate forced regeneration.

  2. Review service records for previous forced regen events.

  3. Ask about typical driving patterns.

  4. Inspect exhaust tip for heavy soot deposits.

  5. Check for fault codes P2002, P2452, P2453.

What it costs to put right

$350 to $4,200 at New Zealand independent workshop rates. That is for this job on its own, not for the car.

An estimate, in NZD, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

Ask the seller

  • “What is the typical daily driving pattern — urban or highway?”
  • “Has the DPF warning light ever come on?”
  • “Has a forced DPF regeneration ever been performed by a dealer?”
  • “Has the DPF ever been cleaned or replaced?”

Now check the SsangYong Rexton you are actually looking at

Everything above is true of the model, and it is free. What it does not tell you is whether THIS car has been looked after: its odometer history and whether the reading has ever gone backwards, whether there is still money owing on it, whether it has been reported stolen, how many owners it has had and what it is really worth today. That comes from the official records for that plate. Enter the plate for the free details, or get the full history and a market valuation from $13.49.

Where this comes from

The failure described above is documented in published sources — owner forums, technical service bulletins, recall notices and workshop write-ups — held in our fault database. The inspection instructions and the cost estimate are KickTyres’ own interpretation of them, and it is a starting point for an inspection rather than a manufacturer statement.

SsangYong Rexton buyer questions

Is dpf clogging on short urban trips serious on a SsangYong Rexton?

We rate it major and common on the SsangYong Rexton. The diesel particulate filter on the 2.2 D22DTF engine requires sustained highway driving above 2000 rpm to complete passive soot regeneration. Vehicles used primarily for short urban trips never reach the exhaust gas temperature threshold needed to burn off accumulated soot, causing progressive DPF blockage. A forced regeneration performed by a dealer clears the blockage, but heavily blocked units that have exceeded maximum ash loading require full DPF replacement.

How much does it cost to fix on a SsangYong Rexton?

$350 to $4,200 at New Zealand independent workshop rates. That figure is for this job on its own. A car showing the symptoms on this page is usually worth either walking away from or negotiating down by at least the repair figure.

Which SsangYong Rexton years are affected?

Our research records this fault on the 2018 onward SsangYong Rexton. Build dates move around, especially on imported cars, so treat the range as the years to look hardest at rather than a guarantee either way. The official records tell you the exact build and first registration date for the car in front of you.

How do I check for it before I buy?

Scan the ECU for DPF soot load percentage and ash load percentage — above 80% soot requires immediate forced regeneration. Review service records for previous forced regen events. Ask about typical driving patterns. Inspect exhaust tip for heavy soot deposits. Check for fault codes P2002, P2452, P2453. Look here: Exhaust system, underbody behind catalytic converter
