DPF soot accumulation on Renault dCi — K9K/R9M over-soot, belt-in-oil contamination risk.
Renault P2463 — DPF soot accumulation on Renault dCi — K9K/R9M over-soot, belt-in-oil contamination risk. Typical UK independent garage cost: £180–£1600.
What actually causes P2463 on a Renault
Renault P2463 — Clip regen first. K9K belt-in-oil debris is a concurrent risk.
Renault engines that log P2463
- 1.5 dCi K9K (Clio/Megane)
- 1.6 dCi R9M (Megane/Kadjar)
How we diagnose P2463 on a Renault
- K9K belt inspection
- Clip regen
- DPF clean if regen fails
- OEM-spec replacement
The common misdiagnosis to avoid
Don't regen a K9K with a failing belt-in-oil — contamination will damage the new DPF if you replace it.
Renault P2463 repair cost in the UK
Expect £180–£1600 including parts and labour at an independent garage. Main-dealer quotes on Renault are usually higher for the same job, and the spread exists because the cheap cause and the expensive cause throw the same code — pay for the diagnosis before you pay for parts.

Reading P2463 on a Renault properly
A generic reader will show P2463 and nothing else. What matters is the freeze-frame data stored with it — engine speed, load, coolant temperature and fuel trims at the moment the fault was logged — plus whether any other module on the Renault has logged something at the same time. Codes rarely arrive alone, and the order they were stored in usually points at which one is the cause and which are the consequences.
Clearing P2463 without fixing it
Erasing the code resets the Renault's readiness monitors as well as the light. The fault returns on the next drive cycle if the cause is still there, and in the meantime the incomplete monitors can stop the car passing an emissions check. After a genuine repair, the car is driven until the relevant monitor completes before it is handed back.
Bob's Mechanical Repairs is an independent garage in Birnam, Dunkeld, Perthshire, with 32 years of Bob's experience on the tools. If P2463 is showing on your Renault, bring any scan results with you — we will read the live data ourselves, confirm which cause it actually is, and price the repair before any work starts.
