AdBlue in diesel in Gerrards Cross

Short answer

AdBlue in diesel Gerrards Cross: if you have put AdBlue in diesel, do not start the engine — call 01293 248666. AdBlue is water-based and sinks to the bottom of the tank, so a drain and flush before the engine runs almost always fixes it.

A mobile technician covers Gerrards Cross and the rest of Buckinghamshire. The job is quoted on the phone before anyone travels, and if it is not something that can be finished at the roadside you will be told that on the call rather than after arrival.

What to do right now in Gerrards Cross

  1. Do not turn the key. Do not press start. Ignition alone can prime the pump on many common-rail cars.
  2. Do not move the vehicle under its own power, and do not put it in gear.
  3. If you are on a forecourt, apply the handbrake and tell the station staff.
  4. Note roughly how much AdBlue went in and how much diesel was already in the tank.
  5. Call 01293 248666. Quantity and whether the engine ran are the two questions that set the job.

AdBlue in diesel in Gerrards Cross — what is different locally

Around Gerrards Cross the vehicle is as likely to be on a forecourt or a verge as on a driveway, so the first question on the call is whether it is in a safe position to be worked on where it stands.

Dealer coverage across Buckinghamshire is thinner than the map suggests once you need a specific marque, and a wasted recovery to the wrong workshop is an expensive way to find that out. Vans and pickups around Gerrards Cross carry larger AdBlue tanks, are refuelled by whoever is on shift, and lose a working day rather than an evening when they are off the road.

Downtime cost is usually what decides between a mobile fix and a recovery, and it is worth being blunt about it on the call rather than after the van arrives. AdBlue freezes at around −11 °C, and Buckinghamshire gets there most winters. Frozen fluid is not spoiled fluid — the tank and lines are heated by design and it thaws on its own — but a genuine level or quality fault reads much the same on the dash, which is why the two get confused.

Location changes the logistics of this job and nothing else about it — the severity is set by what went into which tank. Normally put right by a drain and flush, provided the engine has not been run. Coverage runs across Buckinghamshire on the same basis, with volume and disposal priced in before anyone sets off.

Common questions

Can this be finished at the roadside in Gerrards Cross?

Normally put right by a drain and flush, provided the engine has not been run. If it cannot, you are told on the call rather than after somebody has attended.

How quickly can somebody get to Gerrards Cross?

Attendance in Gerrards Cross is normally same day and the helpline runs 24 hours, but the time that actually matters is the time on site, which for this job is about 60 minutes once the assessment is done.

Does this damage the SCR system?

No. This is the opposite failure. Nothing has entered the exhaust or the SCR circuit — the AdBlue is in the fuel side, where it does not belong. Your SCR system is untouched.
