Build the inspection planTransmissionHigh
Clutch and flywheel wear on loaded vans
- Typically appears
- 100,000+ miles
- What to inspect
- Listen for idle rattle and test the bite point
BodyMedium
Sill and arch corrosion, side door wear
- Typically appears
- Age-related
- What to inspect
- Probe sills and operate the doors repeatedly
ElectricalHigh
Random limp mode and multiple dash warning lights including Check Injection and ESP.
- Typically appears
- 50,000-80,000 miles
- What to inspect
- Open the bonnet and inspect the main wiring loom routing near the gearbox mount and ECU bracket for visible chafing or exposed copper.
SuspensionMedium
Clunking noise or metallic 'twang' from the front end when turning at low speeds.
- Typically appears
- 40,000-70,000 miles
- What to inspect
- Turn the steering wheel lock-to-lock while stationary. Listen for a loud spring binding noise indicating seized front top strut mounts.
InteriorLow
Heater blower fan only operates on speed setting 4, or fails completely.
- Typically appears
- 4-6 years
- What to inspect
- Turn the ignition on and cycle the heater fan through speeds 1, 2, 3, and 4. If 1-3 are dead but 4 blows hard, the resistor pack has failed.
EngineHigh
Distinct metallic rattling noise from the top end during a cold start.
- Typically appears
- 80,000-120,000 miles
- What to inspect
- Ensure the engine is stone cold. Start the van with the bonnet open and listen closely to the right side of the engine for a 3-5 second rattle indicating timing chain stretch.

Build my inspection planFrequently asked questions
How do I judge a Trafic quickly?
Cold start, hot run, hill start, then body condition. That order catches most of the cost.
Are ex-fleet vans better?
Usually yes. Fleet servicing is documented and scheduled, unlike many owner-driver vans.
What kills retail price?
Corrosion and a scruffy load area, even on a mechanically sound van.
Which engine is more reliable for retail stock, the 1.6 dCi or the newer 2.0 dCi?
The newer 2.0 dCi, introduced late 2019, is generally preferred for retail. The older 1.6 dCi, particularly the twin-turbo variants, suffered from complex plumbing and premature wear. The 2.0-litre unit offers better torque, a more robust timing chain setup, and handles heavier payloads with less strain.
How can I verify if the van has the upgraded payload capacity?
Check the chassis plate located on the driver's door pillar and look at the Gross Vehicle Weight figure. Standard short-wheelbase models usually sit around 2,800kg, whereas heavier duty versions display 2,900kg or 3,000kg. This directly impacts the legal payload, which tradesmen will heavily scrutinise before purchasing.
Are the automatic EDC transmissions reliable on the newer models?
The EDC dual-clutch transmission is smooth but requires strict maintenance, demanding a fluid and filter change every 60,000 miles. If a van lacks this specific service history, budget for a gearbox service immediately. Neglected units exhibit jerky shifts between first and second gear, often leading to costly mechatronic failures.
