## Petrol in the AdBlue tank Caernarfon — 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 | Petrol in the AdBlue tank
 | Direction | Into the AdBlue tank
 | Typical cost | £280–£850 typical total, from a £89 call-out
 | Time on site | About 100 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 Caernarfon
- Do not start the engine and do not cycle the ignition repeatedly.
- Ventilate — petrol vapour in a vented AdBlue tank is a real consideration, especially in a garage.
- Do not add AdBlue on top.

## Petrol in the AdBlue tank in Caernarfon — what is different locally
Around Caernarfon 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 Caernarfon 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. Light commercial density around Caernarfon means a fair share of calls are fleet vehicles where the driver and the owner are different people, and the decision has to be made by someone not standing at the vehicle.

Where a vehicle is on contract or on a job, the cheapest outcome is almost always the one that avoids a recovery movement, even if the roadside work costs more per hour. Because North Wales sees sustained cold, the first thing to establish on a level warning in January is whether the fluid has simply not thawed yet.

Local conditions shape how this is done, not whether it can be. That is a question about the fluid and the tank. Frequently needs SCR component work rather than a drain. Quoted before a technician travels. Coverage runs across North Wales on the same basis, with volume and disposal priced in before anyone sets off.
