Don't Start It: AdBlue in a Diesel Tank in Grappenhall
With AdBlue in the diesel tank, your ignition remains off and so does the motor. AdBlue is urea mixed in water. It doesn't burn, it doesn't mix with diesel, and the harm it does begins when the system draws it in. In Grappenhall, AdBlue in a diesel tank caught before your motor runs normally means a drain and a thorough flush, right where the vehicle is. Ring 0333 366 0103 before you do anything else.
Grappenhall, AdBlue in your diesel tank: what to do right away
Things to do:
- Pocket the keys, which stops anyone turning the power on.
- Hazards on, if moving traffic is anywhere close.
- So you can tell us which fluid it was and roughly what quantity, save the receipt or the empty bottle.
- Tell us a postcode starting WA4 3, or whichever street is nearest, and the van finds you straight — so ring wherever you stand.
Never:
- Moving your car even a few yards is no reason to fire up your engine.
- Do not switch the ignition on. On many diesels that alone runs the fuel pump.
- No more fuel added. The AdBlue won't mix, and so it is pointless.
- Don't drive the car anywhere, not even a short stretch up Church Lane.
- Don't try to drain the car yourself by the kerbside.
The attendants on duty at any Grappenhall filling station — the Esso among them — will usually help rolling it clear if you ask. At your own driveway, don't touch it at all.
What does AdBlue do in a diesel tank?
The motor isn't what AdBlue is made for; your exhaust is. From a dedicated reservoir it is fed directly to your exhaust, treating what your engine emits. A fuel pump isn't made to cope with it, and AdBlue was never intended to go through one.
Poured in with your diesel, it keeps apart rather than blending — quite unlike fuel. It's heavier than diesel, so it sinks and gathers at the bottom of that tank, which is where the pickup pulls fuel from. The first thing the system pulls through, after it runs, is the AdBlue. So a vehicle that had AdBlue poured in on a drive in Thelwall last night, and hasn't been started since, is still the easy case: the AdBlue is lying at the bottom of that tank, and nothing has pulled it in.
After it's sucked in, the damage takes two forms. It attacks some metals found in fuel components, attacking any part it reaches until it's cleared completely. And once the water evaporates, the urea turns into crystals that clog filters and settle in narrow passages. Lines holding AdBlue mean harm overnight for a vehicle sitting in Grappenhall. Just in your tank, it stays stable. And there is the water: it offers no protection to the parts that need it most — the injection pump and every injector.
Why is AdBlue in a diesel commonly the bigger fault?
Petrol put into a diesel on Morrisons's forecourt makes the fuel watery — that's the main issue. Blended into the diesel and left still, it's no threat at that stage; using the engine does the harm.
With AdBlue in a diesel, the liquid itself is simply the wrong one. Not burning, it cannot simply be run through. It doesn't stay mixed, and so it cannot be thinned. And crystals and corrosion do not wash out with the next tank of fuel. That is why the flush matters more with AdBlue than with petrol, and why starting your motor "to see" costs more here than almost anywhere else, whether your car is in Wrights green or the middle of Grappenhall.
With AdBlue, the good news is no separate from petrol. If the motor has not run, the AdBlue is still in the tank, and your tank is the simplest part of a fuel system to clear, wherever in Cheshire the car is standing.
How does AdBlue end up in a diesel tank around Grappenhall?
It is not on purpose. Plenty of vehicles have the AdBlue inlet alongside the diesel one, now and then behind a single flap, and mixing them up is easy in poor light. Mostly it is never the filling station: a driver picks up a container driving home and tips it in outside the house.
The ways it takes place are few and familiar. Rushing, outside Grappenhall St Wilfrid's CofE Primary School, after a warning lamp flashed on during the school run, someone tops up the car. A bottle is poured in at the end of the day on a drive just off Albert Road. Or someone unfamiliar with that flap refills your car in dim light, stopped in the car park outside Ram's Head.
It takes place most in the cars people know least: a hire car, a new motor, a company car, or the second car of a household with one diesel and one petrol. Same slip, an identical first response — leave it off — anywhere you happen to be in Grappenhall or the remainder of Cheshire.
Started your engine with AdBlue in your diesel tank in Grappenhall?
In that case, the AdBlue is no longer in that tank. With any running time, it travels to the injection pump and each injector, after passing via your filter and pipework.
Rough running, smoke, lost power, dashboard warnings or cutting out: each may show up, perhaps midway across Grappenhall or returning from Grappenhall Cricket Club. Stop as soon as it is safe, switch off, and do not restart the vehicle to check. Every start pulls more of it through.
Exit the M6, under 3 miles from Grappenhall, at the first junction and park somewhere safe, rather than driving on.
Hopping across Grappenhall to the car park by Grappenhall Library is one matter; driving towards Salford, under 15 miles away, is something else, since every mile carries the AdBlue deeper in. So distance matters. Approximately how far had it come? Tell us.
Once the engine has been started, the flush takes in more, and all of it is done where your car has stopped. Very seldom does it leave long-term damage if it's spotted quickly.
What draining AdBlue from a diesel involves around Grappenhall
Wherever it has stopped in Grappenhall — a filling station, a layby, a drive, a road by St Wilfrid's Parish Centre — our van comes to the vehicle. What went in, about the quantity, plus if your motor has been run: our engineers ask first, because those decide the work.
Next, draining your tank right there removes the polluted diesel and the AdBlue in one go. A full flush counts far more after AdBlue than after petrol, because residue won't wash out by itself. Next, the filter: flushed, or changed when it must be. After that fresh diesel, then a check of the vehicle. The majority of these jobs are a half-hour job once our engineers turn up, provided the motor has not run. Low-noise enough for use outside a house at night, and safe on a working forecourt, our pumps are explosion-proof.
Fresh diesel goes in to bleed the system, and that is the last step. Firing it up comes next, and then you set off from where the car is parked, at Warrington Central or on a drive in Grappenhall. The test before we head off is that it runs smoothly on clean diesel. As the job is done in full where the vehicle is, a workshop never comes into it. Insurers want a VAT invoice and an engineer report, and you get both afterwards.

AdBlue in a diesel tank around Grappenhall: the cost of fixing it
Every job is different, and so no fixed quote would be fair. The cost changes first with how long, if at all, the engine has been running, and next with the amount of AdBlue that got in. After that it rests on where your car is and whether a technician can get to it safely, which is easier on an open drive than in a tight spot behind St. Wilfrid's, Grappenhall.
Before any quote, not after, each enquiry from Grappenhall opens with the same three questions: the liquid, the amount, plus whether it ran. Those answers shrink a range down to one figure.
Before a van sets off, you are told our price on the phone. And you pay on the day, by card or by phone, with nothing in advance. Misfuelling cover is part of plenty of insurance policies, so it pays to look at yours before the van gets there.
