Diesel will not ignite on a spark, so the engine misfires, smokes or refuses to start. A drain normally resolves it. The fix is a mobile fuel drain: a technician attends where the vehicle stands anywhere in Scotland, pumps out the contaminated fuel, flushes the lines and refills with clean fuel — typically 45-90 minutes on site, from £150. Call 01295 380724 and you get the price before anyone travels. The single thing that decides both the outcome and the cost is whether the engine was started.

The moment the key turns, the fuel travels through the lift pump, the filter, the high-pressure pump and the injectors, and every one of those becomes part of the job. That is the whole reason the price range runs from £150 to £1,500. If you have already driven and the vehicle has lost power or cut out, pull over safely — on a Scottish trunk road that may mean the next lay-by rather than the hard shoulder — switch off, and call 01295 380724 rather than trying to reach a garage. ## What it costs Guide prices. Your exact price is confirmed on the phone before a technician sets off. Island and remote Highland jobs are quoted with travel included, so the figure you are given is the figure you pay. Your situation | What is involved | Typical cost | Time on site | Spotted it, engine never started | Drain the tank, flush the lines, refill with clean fuel | From £150 | 45–90 mins | Engine started but not driven | Drain plus a flush of the lines and filter | Mid range | 1–2 hours | Driven a short distance | Drain, flush and a check of the pump and injectors | Higher | 1–3 hours | Driven until it lost power or cut out | Drain, flush and fuel-system diagnosis | Upper end | Assessed on site | AdBlue in the diesel tank | Full drain and flush of tank and fuel lines | Quoted per vehicle | 1–3 hours | [Call 01295 380724 — 24/7](tel:+441295380724) ### Related answers [I put petrol in my diesel car what do i do?](/answers/i-put-petrol-in-my-diesel-car-what-do-i-do/)[How much does it cost to

Leave the vehicle where it is and call 01295 380724. **How long does the drain take in Scotland?** About 45 to 90 minutes on site once the technician arrives. Vehicles that were started or driven take longer, because the lines and filter need flushing as well as the tank. **How much does it cost in Scotland?** Most jobs fall between £150 and £1,500 depending on the vehicle, how much wrong fuel is in the tank and whether the engine was started. You get the price on the phone before we travel. **Will it have damaged the engine?** Only if it has been run through the system. Caught before starting, it sits in the tank and a drain removes it cleanly. **Does insurance cover it?** Often not. Most car insurance policies exclude misfuelling as standard, though some breakdown policies and optional add-ons include it. Check your own wording. **Do you cover rural and island Scotland?** Yes. Technicians attend forecourts, roadsides, homes, farms and workplaces across Scotland, including the Highlands and the islands. Remote jobs are quoted with travel included so the price does not move. ### One operator, four sites Fuel Fixer Scotland is the Scottish arm of Fuel Fixer Ltd.
