Cooling-Fan Diagnostics & Repair
Keep Your Van Running Cool
Same-day diagnostics and OEM fan repairs for Renault & Vauxhall vans
Overheating can warp cylinder heads, blow gaskets and put you off the road for days. Our OEM-grade diagnostics pinpoint cooling-fan faults fast—saving you time and money.
Common Symptoms We Fix
- Fan not switching on at idle
- Overheating in traffic but fine on the motorway
- “STOP – Engine Overheating” dash warning
- Constant fan noise even when the engine is cold
- DTCs:
P0480,P0481,P0691,P0693
Our 5-Step Process
| Step | Detail | Typical Time |
|---|---|---|
| 1. Scan & live-data | Clip / Tech 2 or Bosch KTS to read temps & fan-command signals | 10 min |
| 2. Electrical checks | Relay, fuse, PWM module & harness continuity | 20 min |
| 3. Fan motor test | Bench-test or on-car current draw | 10 min |
| 4. Repair / replace | OEM or upgraded fan assembly fitted | 30–60 min |
| 5. Coolant bleed & road test | Ensure stable temps at idle and under load | 15 min |
Turnaround: Most vans fixed same day if parts are in stock.
DPF / EGR Solutions
Restore Power & Cut Emissions
MOT-legal DPF cleaning & EGR repairs – no illegal deletes
Dashboard warnings, limp mode and poor MPG are usually caused by a blocked DPF or a stuck EGR valve. At DXR Motors we use dealer-level diagnostics and approved cleaning methods to solve the problem without illegal software removal.
Signs You Need Our Help
- DPF / Engine warning light (P242F, P2002, P0401…)
- Reduced power or limp-home mode
- Excessive smoke or frequent regenerations
- Stalling or rough idle after cold start
- Strong diesel smell inside the cabin
Our 5-Step DPF / EGR Service
| Step | Action | Time |
|---|---|---|
| 1. | OEM Clip / Tech 2 live-data & back-pressure test | 20 min |
| 2. | Forced regeneration with live monitoring | 30 min |
| 3. | Chemical DPF flush or EGR cleaner (if required) | 60 min |
| 4. | Hardware repair – valve, sensor or pipework | 30–90 min |
| 5. | Road-test, soot level check & DTC clear | 15 min |
Turnaround: Most vans leave the same day with no warning lights and sharper throttle response.
ECU Reprogramming
Unlock Your Van’s Hidden Potential
Custom economy & performance remaps for Renault & Vauxhall vans
Factory ECU maps are conservative for global fuel grades and climates. Our calibrations safely extract extra power or fuel economy—tailored for real-world UK conditions.
Two Tuned Packages
| Package | Gains | Ideal For |
|---|---|---|
| Eco Remap | +8–12 % MPG +10–15 Nm torque |
Couriers & fleets chasing fuel savings |
| Performance Remap | +25–40 Nm torque Sharper throttle |
Heavy payloads, motorway overtakes |
All maps retain factory safety limits for EGT, RPM and turbo pressure.
Emissions & Fuel-Injection Diagnostics
Stop Guessing—Start Diagnosing
Dealer-grade injector & emissions testing for Renault & Vauxhall vans
Black smoke, rough idle or a failed MOT opacity test usually trace back to injector imbalance or sensor faults. At DXR Motors we use OEM-level equipment to identify the real cause—saving you from costly “parts darts”.
Typical Symptoms We Solve
- Diesel knock or rough idle
- Excessive smoke (black or white)
- Flat spots on acceleration
- Poor MPG despite clean DPF / EGR
- P0201–P02XX injector circuit codes
- Failed smoke opacity test at MOT
Diagnostic Toolkit
| Tool | Purpose |
|---|---|
| Bosch KTS + OEM Clip/Tech 2 | Live rail pressure, injector correction, lambda & NOx readings |
| PicoScope | Crank/cam sync, injector waveform analysis |
| Injector Leak-Off Test | Measures return flow (balances within 10 % spec) |
| Smoke Meter (opacity) | Pre-MOT emission check |
Our Process
- Code Read & Freeze-Frame
- Live Data & Leak-Off Test
- Pressure / Waveform Analysis
- Targeted Repair – injector coding, sensor replacement, wiring fix
- Road-Test & Final Smoke Check
Result: Smooth idle, restored power, MOT-compliant emissions.
Turbocharger Repair & Replacement
Restore Boost, Restore Power
OEM-spec turbos, dynamic balancing & same-day turnaround
Whistling, smoke or limp mode? A worn turbo will cripple performance and economy. DXR Motors installs OEM-spec units, genuine gaskets and performs dynamic balancing to bring your van back to full boost—safely.
Warning Signs of Turbo Failure
- Siren / dentist-drill noise on spool-up
- Oil smoke from exhaust under load
- Loss of boost; van drops into limp mode
- P0299 “Underboost” or P0234 “Overboost” codes
- Oil in intercooler pipes
Catch it early and a cartridge rebuild may be all that’s needed; ignore it and you risk DPF clogging or engine damage.
