Accidentally put AdBlue in diesel cranleigh
Accidentally put AdBlue in diesel cranleigh: an accidental AdBlue fill is recoverable as long as the engine has not been started. Do not turn the key, do not move the vehicle on its own power, and call for a drain.
This is the most common call on this site and it very rarely ends badly, because most people notice at the pump. The bottle is designed to look like it belongs in the same place, the AdBlue filler is often beside the diesel filler under the same flap, and on a forecourt at night the two are easy to confuse. Noticing before you start the engine is the whole ball game. A mobile technician covers Cranleigh and the rest of Surrey, and the job is quoted on the phone before anyone travels.

What to do right now in Cranleigh
- Do not turn the key. Do not press start. Ignition alone can prime the pump on many common-rail cars.
- Do not move the vehicle under its own power, and do not put it in gear.
- If you are on a forecourt, apply the handbrake and tell the station staff.
- Note roughly how much AdBlue went in and how much diesel was already in the tank.
- Call 01293 248666. Quantity and whether the engine ran are the two questions that set the job.
AdBlue in diesel in Cranleigh — what is different locally
Around Cranleigh 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.
Specialist SCR workshops in Surrey are scattered, and the nearest one to Cranleigh may not be the nearest one that can actually clear this particular fault. Operators around Cranleigh tend to run vehicles hard and top up from bulk, which puts fluid quality rather than driver error at the top of the likely-cause list.
The cost split is simple and it is stated up front: the call-out, the drain and flush, and separately anything the SCR system itself needs. Cold mornings in Surrey produce a run of calls that turn out to be nothing more than fluid below −11 °C in a tank that has not yet warmed, and telling that apart from a real fault saves a wasted visit.
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 Surrey on the same basis, with volume and disposal priced in before anyone sets off.
