“I drove 3 miles before the car started sputtering and cut out...”
Driving a diesel car on unleaded petrol is every motorist’s worst nightmare. Petrol strips away critical lubrication inside high-pressure common-rail pumps, causing airlocks and misfires. Most dealerships will quote £3,000+ for a full fuel system replacement.
Watch how our Fuel Fixer wrong fuel doctor saved this engine right at the roadside:
Full Fuel Drain: Safely evacuated 100% of the contaminated petrol-diesel mix from the fuel tank using ATEX-certified extraction gear.
High-Pressure System Flush: Flushed the fuel lines, common rail, and replaced the contaminated fuel filter to strip out volatile petrol solvents.
ECU Airlock Purge: Used diagnostic tools to purge airlocks and re-prime the fuel system without dry-cranking the high-pressure pump.
Fresh Diesel & Clean Restart: Topped up with fresh diesel, turned the key, and it started cleanly on the first try with zero mechanical damage! 🛠️💨
Total downtime: Back on the road in under an hour without an expensive tow truck!
