AdBlue in the petrol tank
AdBlue in the petrol tank means a water-based urea solution is sitting under the fuel, around the in-tank pump. Do not switch the ignition on — it primes the pump. Call 01295 380724 for a mobile drain and flush.
On a petrol car the fuel pump lives inside the tank, submerged. That is the difference that matters here: the contamination is not merely somewhere in the tank, it is around the pump body, the strainer and the level sender. Urea is corrosive to zinc and aluminium and it crystallises white as it dries, which is why the strainer gets inspected rather than assumed clean.

What to do right now
- Ignition off, and keep it off — priming happens before cranking.
- Do not attempt to siphon it yourself with a fuel siphon. It draws off the top; the AdBlue is at the bottom.

What a technician actually does
Complete drain, pump assembly and strainer inspection, petrol flush, filter where fitted, refill, run-up and a fuel-pressure check.
Why this is not the same job as the other direction
This is contamination of the fuel side. The SCR system itself is untouched, which is why this direction is the recoverable one — provided the engine has not been run. Starting it is what turns a drain into pump and injector work.
Common questions
Can I siphon it out myself?
A siphon takes fuel off the top of the tank. The AdBlue is at the bottom. You will remove petrol and leave the problem.
Will the fuel pump need replacing?
Usually not if the vehicle was never started, but it is inspected rather than assumed, and a pump replacement would be quoted before any work.
How long does it take?
About an hour on site for a standard drain and flush.
What customers say
4.8 out of 5 from 2,190 Trustpilot reviews. What reviewers mention most is that the technician stayed calm and professional with a driver who was embarrassed and stressed, and that somebody arrived when they said they would.
The most common criticism is price. People do not expect a wrong-fluid job to cost what it costs, and that is a fair complaint to publish rather than bury. The answer is the From just £89 call-out fee, a quote given on the phone before a technician travels, and being told when a job cannot be done at the roadside rather than after somebody has arrived and charged for the visit.
