Problems: Vauxhall Vivaro
The Vauxhall Vivaro has established itself as a reliable workhorse in the European light commercial vehicle segment. Popular among contractors, couriers, and campervan converters, it shares its technical roots with the Renault Trafic and Nissan Primastar. Despite its solid reputation, each generation of the Vivaro is known for several recurring mechanical and electronic shortcomings.
Vauxhall Vivaro B - Common Issues (2014–2019)
The second-generation Vivaro introduced modern engines, better comfort, and stricter emissions technology. While offering improved driving characteristics, the increased technical complexity resulted in several well-known reliability concerns.
AdBlue & SCR System Errors
- Symptom: Emissions warning messages, engine restart countdown, reduced power.
- Cause: Failed NOx sensors, blocked AdBlue injectors, or crystallised SCR components.
- Fix: Replace defective SCR parts and perform system recalibration using diagnostics.
EGR System Carbon Build-Up
- Symptom: Poor throttle response, uneven acceleration, engine fault light.
- Cause: Soot accumulation in the EGR valve and cooler, common with short-distance use.
- Fix: Clean or replace EGR components and ensure regular longer driving cycles.
Timing Chain Wear (1.6 CDTI)
- Symptom: Rattling noise during cold starts.
- Cause: Chain stretch caused by oil degradation or delayed servicing.
- Fix: Install a new timing chain kit and adhere to oil service intervals.
Boost Hose Failure
- Symptom: Sudden loss of power with loud air escape noise.
- Cause: Turbo pressure forcing poorly secured intercooler hoses loose.
- Fix: Fit reinforced hoses or upgraded clamps.
Electronic Handbrake Faults
- Symptom: Parking brake warnings or failure to engage/release.
- Cause: Actuator failure or calibration errors.
- Fix: Recalibrate or replace the electronic brake module.
Vauxhall Vivaro A – Common Issues (2001–2014)
The first-generation Vivaro focused on durability and simplicity, featuring mainly diesel engines between 1.9 and 2.5 CDTI. With age and mileage, several characteristic faults became increasingly common.
Diesel Injector Leakage
- Symptom: Difficult starting, uneven idle, fuel smell under the bonnet.
- Cause: Failed injector sealing washers allowing combustion gas leakage.
- Fix: Replace injector seals and clean mounting surfaces.
Manual Gearbox Bearing Noise
- Symptom: Gearbox whining in higher gears.
- Cause: Excessive wear of internal bearings in 6-speed transmissions.
- Fix: Gearbox overhaul with reinforced bearings.
Turbo Wear & Power Loss
- Symptom: Reduced engine performance and excessive exhaust smoke.
- Cause: Restricted oil supply to turbocharger bearings.
- Fix: Replace turbo and oil lines, ensure proper lubrication.
Timing Chain Noise (2.5 CDTI)
- Symptom: Metallic knocking at engine startup.
- Cause: Stretched timing chain and worn tensioners.
- Fix: Replace timing components and maintain oil quality.
Moisture-Related Electrical Problems
- Symptom: Intermittent electrical failures or no-start conditions.
- Cause: Water ingress near the ECU and fuse box.
- Fix: Seal drainage points and repair corroded connectors.
