Don't Start It: AdBlue in a Diesel Tank in Throxenby
AdBlue in the diesel tank? Then leave your engine off — and the ignition as well. Chemically, AdBlue is simply urea in water. It doesn't burn, it does not mix with diesel, and the damage it does begins when the system draws it in. If your engine has not run yet, AdBlue in a diesel tank is normally emptied and thoroughly cleaned where your car sits around Throxenby. Nothing comes before calling 0333 366 0103.
Your next steps straight away, Throxenby: AdBlue in your diesel tank
Do these:
- Pull the keys out, and so no one switches your ignition on.
- Hazards on, if moving traffic is at all close.
- The empty bottle or your receipt tells us the product and the quantity, so do not bin it away.
- Call us from where you are. A postcode starting YO12 5, or the name of the nearest street, brings our van to you without a search.
Do not do these:
- Not even for a second, and not to shift your car: your motor stays off.
- Turning the key to ignition by itself starts the pump going on plenty of diesels. Avoid it.
- Pouring in more diesel doesn't work: AdBlue settles out rather than blending.
- Even a short way down Southlands Grove is too far to drive the vehicle.
- Do not try to drain the vehicle yourself at the kerbside.
At a forecourt in Throxenby, whether it's the JET or another one, ask the staff to help you roll your car away from the petrol pump. Parked on your own driveway? Then it remains exactly where it is.
AdBlue in a diesel tank: what it does
Not the engine but the exhaust is where AdBlue is meant to go. Its own tank keeps it, and from there it is fed into the exhaust, and there it treats the fumes. A fuel pump isn't designed to take it, and AdBlue was never supposed to go through one.
Inside a diesel tank it behaves really differently from fuel. It does not mix in. Heavier than diesel, it drops and collects below it — the very spot the pickup draws from. When the pump runs, the AdBlue is first to go through. Until then it waits beneath your diesel, and that is how a vehicle topped up in Newby last night and not started remains the straightforward one, as long as nobody touches your key.
After it's sucked in, the damage comes in two forms. As its water goes, the urea left behind crystallises, and the crystals block filters and settle in fine passages. And it is corrosive to some of the metals a fuel system is made from, and so it keeps working on the parts it hits for as long as it stays there. Overnight, a car sitting around Throxenby with AdBlue through its pipework gets worse; where it is only in the tank, it doesn't. And there is the water: it brings no protection to the components that rely on it the most — the injection pump and each injector.
Why is AdBlue in a diesel regularly the bigger problem?
Petrol pumped into a diesel on Penny Petrolium's forecourt makes your fuel thin — that is the main problem. No damage comes as long as it stays unused, blended into the diesel — only once the engine works on it.
The trouble with AdBlue in a diesel is a totally wrong substance. Not burning, it cannot just be run through. It doesn't stay mixed, so it can't be diluted. And crystals and corrosion don't wash out with the next tank of fuel. That is why the flush counts more with AdBlue than with petrol, and why starting the motor "to see" costs more here than almost anywhere else, whether the vehicle is in Prospect Mount or the middle of Throxenby.
The same good news holds as with petrol. Emptying a tank is the easiest job on a fuel system, and with no start-up, the AdBlue stays in there — wherever across North Yorkshire the car sits.
How AdBlue ends up in a diesel tank around Throxenby
It's not deliberate. Plenty of vehicles have the AdBlue cap alongside the diesel one, occasionally under a single flap, and mixing them up is simple in poor light. It usually happens outside the house, from a container bought on the journey home, not at the forecourt.
The ways it happens are few and familiar. Halfway through the morning drop-off, the dashboard flags it up, and outside Newby and Scalby Academy the refill is hurried. After work, a bottle is tipped in on a drive near Throxenby Lane. Another version: darkness, a pub car park by The Rosette, and a driver using that flap for the first time.
It comes up most in a hire car, a brand-new vehicle, a fleet vehicle, or the other motor in a family with one of each fuel types — the vehicles people know least. Wherever you are in Throxenby or the rest of North Yorkshire, it is the same slip and the same first answer: leave it off.
Started the engine with AdBlue in the diesel tank around Throxenby?
If so, the AdBlue is no longer in the tank. Via the filter, through the lines, and — given any running time — into the high-pressure pump and every injector: that's how far it travels.
You may see the engine running unevenly, smoking, losing power, showing warning lights or cutting out, perhaps on the way back from Low Wood or halfway across Throxenby. Stop when safe. Switch off. Keep the car off instead of restarting it to check. Each start pulls more of it through.
Throxenby lies under 50 miles from the Petuaria Way; if you were on it, exit by the first junction and stop safely rather than driving on.
A quick hop across Throxenby to the car park by Wreyfield Drive Methodist is one thing; heading towards York, under 50 miles away, is something else, since each mile carries the AdBlue deeper in. So mileage counts. Approximately how far had it come? Tell us.
There is more to rinse out once the motor has been run, and our technicians do all of it where the vehicle has come to a stop. Very rarely does it leave permanent damage when it is spotted quickly.
Throxenby: how AdBlue is emptied from a diesel
Anywhere it has stopped in Throxenby — a filling station, a layby, a driveway, a street by Scarborough Table Tennis Centre — our van comes to your vehicle. The job depends on three answers, which our technicians get first — which fluid went in, the amount, and whether your motor has run.
Then that tank is drained where the vehicle stands, and so the tainted fuel and the AdBlue come out together. With AdBlue, more so than with petrol, flushing counts: the fuel system is cleaned right through since what remains will not wash out by itself. Next, the filter: flushed, or replaced when it must be. After that fresh diesel, and then a check of the vehicle. Engine not run? In that case expect about half an hour once we are there for most jobs. Explosion-proof pumps mean a live forecourt safe to work on, and they're quiet enough to spare the neighbours at night.
The last step is to bleed your system on fresh diesel. Whether it is a parking space at Scarborough or a driveway around Throxenby, that is where our engineers fire it up and you drive off. Before leaving, our engineers check it is running properly with fresh diesel in. Our technicians do it all wherever the car has stopped, and it never needs to go to a garage. You receive a VAT invoice and an engineer report later, which is what insurers want.

Throxenby: what AdBlue in a diesel tank costs to fix
Each job is different, and so not one single price is fair. Three things move the cost: whether your engine has been running and for how long, how much AdBlue was put in, and where the car is. That last one comes down to whether a van can get to it safely, and an open driveway is simpler than a tight space behind St Luke.
That's why every call from Throxenby starts with the same three queries, asked before giving a figure, not after: what was put in, how much, and if it has run. Their answers shrink a range right down to one figure.
You hear that quote on the phone, before anyone heads out, and you pay on the day, by card or by phone, with nothing upfront. As the van is travelling, dig out your policy: plenty include misfuelling.
In Throxenby and still alongside the vehicle?
Then, the most helpful thing to do with your vehicle is to leave it. Motor off, keys out, ignition off. Petrol in Diesel takes over the rest, in Throxenby or wherever in North Yorkshire, once you phone 0333 366 0103 to say it's AdBlue, roughly what quantity, and if it ran.
