Diesel in the AdBlue tank Stevenage — the severity verdict
| 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 | Call-out £89 to £199 · drain £199 to £1,999 |
| Time on site | About 90 minutes |
| Call-out | Call-out from £89 |
| Helpline | 01293 248666, 24 hours |
The call-out is £89 to £199. 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 Stevenage
- 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 Stevenage — what is different locally
Around Stevenage 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.
Getting to a dealer from Stevenage usually means a recovery movement, so the sequence matters: drain and flush first, establish whether the system has latched, and only then decide whether a dealer visit is unavoidable. HGV traffic through Stevenage changes the arithmetic — tank volumes an order of magnitude larger, disposal costs to match, and a loaded trailer that cannot simply be left.
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 Hertfordshire 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.
Whether this job is a roadside one depends on the direction of contamination rather than on the postcode. Frequently needs SCR component work rather than a drain. Quoted before a technician travels. Coverage runs across Hertfordshire on the same basis, with volume and disposal priced in before anyone sets off.

Common questions
How quickly can somebody get to Stevenage?
Attendance in Stevenage 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 90 minutes once the assessment is done.
What if my vehicle is already at a garage in Stevenage?
That is fine. The work is mobile, so it happens wherever the vehicle is standing — a forecourt, a yard, a driveway or somebody else's workshop.
Can I dilute it with more AdBlue?
No. Diesel does not dissolve in AdBlue and it does not stop coating the pump internals and the injector because there is more fluid around it. Topping up adds cost to the drain.
