Diesel in the AdBlue tank in Chelmsford, drained on the spot
Put the keys in your pocket and ring 01295 380724. Diesel in the AdBlue tank in Chelmsford is a drain-and-flush job done at the roadside, on the forecourt or on your drive — no tow, no garage. Call-out from £89, roughly 1 to 3 hours on site, price agreed first.
Diesel in the AdBlue tank contaminates the urea and can ruin the SCR dosing pump and injector, so it must come out before starting.

The drain itself, step by step in Chelmsford
They bring the fuel. Once the tank is empty and the lines are flushed, the drainer adds enough of the correct fuel to get the engine running and to reach a filling station, then checks for warning lights before handing the keys back.
What to ask on the phone before a drainer travels to Chelmsford
You are going to pay for the job, so it is worth two minutes on the phone first. These are the questions that separate a straight quote from a surprise at the roadside.
- Do you take card payment at the roadside?
- Will you dispose of the contaminated fuel, and can I have a note of it?
- How much more if the engine has already been started?
- Will you check the filter and pump if the engine ran?
- What is the total, not just the call-out, if it is a straight drain?
What to do right now
- Keep the engine off and put the keys somewhere you will not absent-mindedly use them.
- Move the car only by pushing, with help, and only if it is blocking a pump.
- Phone 01295 380724 and describe what happened.
- Confirm the quote — call-out from £89 — and the arrival window.
- The drainer empties the tank into a sealed container and flushes through.
- After a refuel and a test run, the waste fuel leaves with the drainer for licensed disposal.

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 Chelmsford.
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 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.
How long does a drain take in Chelmsford?
Usually 1 to 3 hours on site once the drainer arrives. Longer if the engine was started, because the filter and lines need flushing as well as the tank.
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.
How quickly can a drainer reach me in Chelmsford?
Usually the same day and often within a couple of hours. The operator gives you an arrival window on 01295 380724 before you agree.
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.
The engine is running rough — is that the wrong fuel?
If it started shortly after filling up, very likely. Pull over when it is safe, switch off and call 01295 380724.
