## Diesel in the AdBlue tank Molesey — the severity verdict

**Key facts**
 | Severity | Component risk Frequently needs SCR component work rather than a drain. Quoted before a technician travels.
 | What went where | Diesel in the AdBlue tank
 | Direction | Into the AdBlue tank
 | Typical cost | £260–£750 typical total, from a £89 call-out
 | Time on site | About 90 minutes
 | Call-out | From just £89 call-out fee
 | Helpline | 01293 248666, 24 hours
£89 is the call-out. An AdBlue tank drain and flush is quoted on the phone before a technician travels. If the SCR system needs component replacement — dosing injector, pump, tank or catalyst — that is separate, and you will be told before any work starts. If this is a job we cannot fix at the roadside, we will tell you that on the phone rather than after we arrive.

## What to do right now in Molesey
- Do not start the engine. The dosing pump runs on many vehicles as soon as the system is awake.
- If it is already running, switch it off now rather than driving to a garage.
- Do not top it up with AdBlue to dilute it. Dilution does not undo hydrocarbon contamination of the pump and lines.
- Call 01293 248666 and say how much diesel went in and whether the engine has run since.

## Diesel in the AdBlue tank in Molesey — what is different locally
Around Molesey 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.

Distance to a marque dealer from Molesey is the single biggest variable in what this ends up costing, and it is worth settling before anything is towed. Vans and pickups around Molesey 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.

A drain done on the day is usually cheaper than a recovery plus a workshop slot plus the wait, but that is only true where the contamination direction allows it. AdBlue freezes at around −11 °C, and Surrey 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.

The geography affects arrival time and disposal, not the outcome; that is decided by the contamination direction and whether the engine was run. Frequently needs SCR component work rather than a drain. Quoted before a technician travels. Coverage runs across Surrey on the same basis, with volume and disposal priced in before anyone sets off.

## Common questions

### How quickly can somebody get to Molesey?

### Do you cover the area around Molesey as well?
Yes. Cover runs across Surrey on the same terms, from the same call-out fee, and the job is priced identically wherever in the county it is.
