Water in AdBlue tank in Sawston Cambridge? Drained where it stands
Stop, switch nothing on, and call 01295 380724. Local drainers across Sawston Cambridge handle water in the adblue tank every week: tank out, lines flushed, clean fuel in, all where the vehicle is parked. Expect 1 to 3 hours on site and a call-out from £89, with the full price given before they leave for you.
AdBlue is a precise mix. Extra water takes it out of specification and the exhaust treatment system logs a fault. That is why the ignition is the one thing not to touch.

When a drainer arrives in Sawston Cambridge
A good drainer asks three questions before touching anything: what fuel went in, how full the tank is, and whether the engine was started. The answers decide whether it is a straight drain or a drain plus a flush of the filter and pump. Either way it happens where the vehicle is parked.
What to ask on the phone before a drainer travels to Sawston 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.
- Do you take card payment at the roadside?
- Can you work on the forecourt, or does the car need to be moved?
- What is the total, not just the call-out, if it is a straight drain?
- How much more if the engine has already been started?
- Will you dispose of the contaminated fuel, and can I have a note of it?
What to do right now
- Leave the key out of the ignition and do not unlock the steering to push the car.
- If you are at the pump, tell the cashier; most forecourts will let the car stay in a bay.
- Call 01295 380724. Say what fuel went in, roughly how much, and where you are.
- Agree the price on the phone. Nobody travels until you have.
- The drainer pumps out the tank, flushes the lines and adds clean fuel.
- They start the engine, check it runs cleanly and take the old fuel away.

Where you can be drained in Sawston Cambridge
Most drains in Sawston Cambridge happen on the forecourt where the mistake was made. The rest are at the roadside after the car cut out, or on a drive the next morning. All three work; the vehicle does not need to be towed anywhere.
The same van covers Foxton Cambridge, Newton Cambridge, Hauxton Cambridge and Great and Little Shelford Cambridge, which usually keeps arrival times short across this side of Cambridge.

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 Sawston 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 hire car or a company car?
Yes. Tell the hire company or fleet manager too; many prefer a drain on site to a recovery.
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.
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.
Can I pay by card?
Yes. Card payment is taken on site once the job is done.
What if I have already driven home?
Leave it on the drive with the engine off and call 01295 380724. The drainer can do the whole job at your house.
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.
