Diesel in the AdBlue tank in Dorking: a local drainer comes to you
The single most useful thing you can do now is nothing — leave the engine off. Then call 01295 380724. A drainer who works Dorking drains diesel in the adblue tank on the spot, flushes through and refuels, typically in 1 to 3 hours, with a call-out from £89 confirmed up front.
Diesel in the AdBlue tank contaminates the urea and can ruin the SCR dosing pump and injector, so it must come out before starting. That is why the ignition is the one thing not to touch.

Questions worth asking before you book a drain in Dorking
Most bad experiences with a fuel drain come from not asking these up front. Ask them all.
- Do you take card payment at the roadside?
- What is the total, not just the call-out, if it is a straight drain?
- Do you bring clean fuel, and is it included?
- How long until you reach me in Dorking?
- Is the vehicle over 3.5 tonnes, and does that change the price?
What to do right now
- Don't press the start button or turn the key.
- Take a photo of the pump display: it shows the fuel type and the litres.

- Agree the price before booking — the call-out starts at £89.
- The drainer empties the tank and flushes the system where the car stands.
- They refuel, start the engine and check it before handing back the keys.

From the drainer's notebook
Fuel Fixer, the company behind Wrong Fuel Drain, holds a rating of 4.8 out of 5 from 2,190 reviews on Trustpilot, on a profile claimed since 2017.
Across recent reviews, the themes customers raise most often are staff who stay polite, professional and reassuring during what is a stressful situation, and how quickly a technician arrives and gets the vehicle back on the road in Dorking.
The most common criticism is price. Some customers have felt the cost of an emergency drain was steep for a job that takes under two hours, and that is fair comment on an emergency call-out. It is why the misfuel call-out fee now starts at just £89 and why the full figure is quoted on the phone before a technician sets off — so nothing about the cost is a surprise at the roadside.
Common questions
What does it cost in Dorking?
The call-out starts at £89. The full price depends on the vehicle and how far the fuel got, and it is confirmed on 01295 380724 before anyone travels.
Will you bring fuel?
Yes. The drainer adds enough of the correct fuel to start the engine and reach a filling station.
Will my engine be damaged?
Not if it has not been started. The wrong fuel sitting in the tank touches nothing that a drain cannot clear. Damage starts once it circulates.
Do I need to move the car off the forecourt?
Only if it is blocking a pump. Push it into a bay with help and the engine off; the drainer can work there.
Will the car need a service afterwards?
Not after a straight drain. If the engine ran on the wrong fuel, the drainer will tell you whether the filter should be changed.
Is the drain messy?
No. The fuel is pumped into a sealed tank on the van, and a drip tray catches anything from the connection. The area is left as it was.
