Diesel in the AdBlue tank Cosham Portsmouth — 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 | £260–£750 typical total, from a £89 call-out |
| Time on site | About 90 minutes |

| 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 Cosham Portsmouth
- 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 Cosham Portsmouth — what is different locally
Most calls in Cosham Portsmouth come from a vehicle already parked on a residential street, which means the work is a planned on-site job rather than a recovery, and the technician can take the time to drain properly instead of clearing a live lane.
Because Cosham Portsmouth sits inside a large urban dealer network, a vehicle that truly needs a dealer-level reset is not far from one — the question is whether it needs one at all. The local vehicle mix is domestic, so the tanks are small and a single bottle of the wrong fluid is enough to take the system out.
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. Winter around Cosham Portsmouth brings the freezing question up constantly: the fluid freezes near −11 °C, the system is designed for it, and the dashboard message is the only thing that needs interpreting.
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 Portsmouth on the same basis, with volume and disposal priced in before anyone sets off.
