Diesel in the AdBlue tank in Barnwell Cambridge, drained on the spot
The single most useful thing you can do now is nothing — leave the engine off. Then call 01295 380724. A drainer who works Barnwell Cambridge 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.
Here is why it matters. Diesel in the AdBlue tank contaminates the urea and can ruin the SCR dosing pump and injector, so it must come out before starting.

What to expect from the drainer in Barnwell Cambridge
Most of the time is spent draining. A full tank of the wrong fuel takes longer to pump than a few litres, so the drainer will tell you roughly how long it will be once they see the gauge. After that it is a flush, a refuel and a test run before they leave.
What to ask on the phone before a drainer travels to Barnwell Cambridge
A drainer should be happy to answer all of these on the phone. If they will not give a price before travelling, ring someone else.
- How much more if the engine has already been started?
- Can you work on the forecourt, or does the car need to be moved?
- Do you bring clean fuel, and is it included?
- Will you check the filter and pump if the engine ran?
- Is there an extra charge at night or at the weekend?
What to do right now
- Stop. Do not start the engine, even for a moment.
- Note the fuel type, the amount you put in and whether the car was already low.
- Ring 01295 380724 and give the location — a postcode or the filling station name is enough.
- Get the full price and an arrival time before you agree.
- A drainer attends, drains and flushes the fuel system where the car is parked.
- Clean fuel goes in, the engine is run, and you drive to the next forecourt to fill up.

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 Barnwell Cambridge.
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
Can you drain a van or a lorry?
Vans, yes, routinely. Vehicles over 3.5 tonnes are quoted separately because of the volume involved.
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.
I only put a little in — do I still need a drain?
In most modern diesels, yes. Even a small amount of petrol reduces the lubrication the pump depends on. A drain is cheap compared with a pump.
Can I drive to a garage with diesel in the adblue tank?
No. Every mile pushes the fuel further through the pump and injectors. A drainer comes to you, so there is no reason to move the car under its own power.
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 you cover all of Barnwell Cambridge?
Yes — forecourts, roadsides, homes and workplaces across Barnwell Cambridge and the surrounding area.
