Don't Start It: AdBlue in a Diesel Tank in Laity Moor
AdBlue in your diesel tank? Then leave the motor off — and your ignition too. Urea mixed in water is what AdBlue is. It doesn't burn, it doesn't mix with diesel, and the damage it does starts when the fuel system draws it in. If your engine hasn't run yet, AdBlue in a diesel tank is normally emptied and carefully cleaned where the car stands around Laity Moor. First, phone us on 0333 366 0103.
Those opening minutes: AdBlue in your diesel tank in Laity Moor
Do:
- Keys out — then no one can switch anything on.
- Put the hazards on if you're at all near moving traffic.
- The empty bottle or your receipt tells us the product and the quantity, so don't bin it out.
- Tell us a postcode starting TR16 5, or whichever street is nearest, and the van finds you straight — so ring wherever you are.
Never:
- Shifting the car even a short way is no reason to fire up the engine.
- Plenty of diesels power their pump the instant the ignition comes on, and so leave it off.
- No more fuel added. The AdBlue will not blend, so it is wasted.
- Never drive the vehicle anywhere, not even a short way down Coast to Coast.
- No emptying it yourself, at all, at the roadside.
Rolling the car off the pumps is a job for attendants to help with, whichever Laity Moor forecourt you're on, the Texaco or any other. Stopped on your own driveway? Then it remains just as it is.
AdBlue in a diesel tank, and what it does there
Made for your exhaust, AdBlue has no business in the motor. From a separate reservoir it is fed straight to the exhaust, treating what the engine emits. A fuel pump is not designed to take it, and AdBlue was never intended to go through one.
It doesn't combine. After it's poured into the tank, AdBlue behaves not at all like diesel. Heavier than diesel, it drops and collects below it — the same place the pickup draws from. The first thing your fuel system pulls through, after it runs, is the AdBlue. So a vehicle that had AdBlue poured in on a drive in Manor Parsley last night, and has not been started since, is still the straightforward case: the AdBlue is lying at the bottom of your tank, and nothing has drawn it in.
From there it does two kinds of damage. As its water goes, the urea left behind crystallises, and the crystals block filters and settle in fine passages. And it's corrosive to some of the metals a fuel system is made from, and so it keeps labouring on the components it hits for as long as it stays there. Where the AdBlue has reached the lines, waiting overnight around Laity Moor makes things worse. Inside that tank only, waiting does nothing. The water in it does harm of its own: your high-pressure pump and the fuel injectors rely on diesel to lubricate them, and water offers them nothing.
Why is AdBlue in a diesel regularly the bigger issue?
Petrol put into a diesel on Tesco's forecourt leaves your fuel thin — that is the main problem. It mixes with the diesel, and while it is inside the tank it causes no harm; the damage comes from running your engine on it.
AdBlue in a diesel is a fault of the wrong substance altogether. Not burning, it cannot simply be run through. Crystals and corrosion stay after the following fill, and AdBlue splits again out of your diesel, so thinning it won't work. Hence the flush matters more, and trying the engine "to see" does more harm with AdBlue than nearly any other slip — in North Country or the centre of Laity Moor equally.
The good news is the same as with petrol. Clearing a tank is the easiest part on any fuel system, and with no start-up, the AdBlue stays in it — wherever around Cornwall your vehicle sits.
Laity Moor: how AdBlue ends up in a diesel tank
Many motors place the AdBlue filler alongside the diesel cap, now and then behind a single flap, and after dark the two can appear identical. Nobody means it. Most of the time it occurs with a bottle bought on the way home and poured in on the driveway, not at the forecourt.
A couple of familiar ways cover most cases. Hurrying, outside Treleigh Community Primary School, after a warning lamp came on during the school run, someone refills your car. A bottle is poured in at the end of the day on a drive just off Chapel Hill. Or your car is topped up in the car park at the pub in the village, in poor light, by someone who has never opened that flap before.
It takes place most in the cars people know least: a hire car, a new car, a company car, or the second motor of a household with one diesel and one petrol. Anywhere around Cornwall, Laity Moor included, the slip does not change, and nor does the first step: leave it switched off.
AdBlue in the diesel tank in Laity Moor, and the motor started?
In that case, the AdBlue is no longer in that tank. Through your filter, through the pipework, and — given any running — on to the injection pump and every injector: that's how far it has gone.
You may see your motor running unevenly, smoking, losing power, showing warning lights or cutting out, maybe on the way back from Trenoweth Playing Field or halfway across Laity Moor. Stop as soon as it is safe, switch off, and do not restart it to check. Every start pulls more of that through.
If you were on the M5, over 50 miles from Laity Moor, come off at the next exit and stop somewhere sensible rather than pressing on.
Every mile pushes the AdBlue deeper in. That's why a hop across Laity Moor to park near Mawla Methodist Church and a drive of under 10 miles towards Truro are very different jobs. Tell us roughly how far it had come.
Wherever the car came to a halt is where all of it gets done, even with more to rinse out after your engine has been run. Permanent damage is very uncommon when it's noticed soon.
Emptying AdBlue in a diesel in Laity Moor: what it takes
Our technicians come to the car, wherever it has stopped around Laity Moor: a side street near Redruth Old Cornwall Society Museum, a drive, a lay-by or a forecourt. The work depends on three replies, which our technicians ask for first — what was put in, the amount, and if your motor has turned over.
On the spot, the tank is then emptied, and both the polluted diesel and the urea leave at once. With AdBlue, far more than with petrol, flushing matters: the whole system is flushed all the way through because what remains won't flush away by itself. Clean diesel goes in after your filter is flushed — or swapped, if it needs to be — and then your car is tested. The majority of these jobs are a half-hour visit once we get there, if the engine hasn't run. Explosion-proof pumps mean a busy forecourt sensible to work on, and they run quiet enough not to disturb the street at night.
Bleeding the system with clean diesel comes at the end. After that our technicians start the engine and you drive off, whether from a parking space at Redruth or a drive in Laity Moor. We confirm it runs smoothly on new diesel before leaving. Since the job is done in full where your car is, a workshop never comes into it. You get a VAT invoice and an engineer report later on, which is what insurers want.

AdBlue drains around Laity Moor and across Cornwall
Mawla, Cambrose and Parc Erissey are among the places near Laity Moor that the same vans serve, together with much of Cornwall further out, throughout the TR postcode area. Guessing doesn't help close to a county line or anywhere tricky to pin down; ring and ask.
No moving is needed. In Laity Moor, a coastal area, a mobile service works: your vehicle is drained on the spot, whether in a driveway, a side street, a parking area or a filling station.
Laity Moor: what AdBlue in a diesel tank costs to fix
There's no fair single price, because the jobs are not the same. The price changes first with how long, if at all, the engine has been running, and next with the quantity of AdBlue that was put in. After that it turns on where your car is and whether a van can get to it safely, which is simpler on an open driveway than in a tight gap behind North Country United Methodist Church.
Which fluid got in, how much, plus whether it ran: every Laity Moor enquiry opens with precisely that, before any quote, never afterwards. The replies turn a range into a straight price.
Priced on the call before the engineer heads out, it is settled on the day — card or phone, no deposit. As our engineer is travelling, dig out your policy: many cover misfuelling.
Laity Moor: still next to the car?
In that case, touch nothing — that's the most helpful step there is. Ignition off, engine off, keys out. Tell us it was AdBlue, roughly how big an amount, and if it ran, on 0333 366 0103. After that Petrol in Diesel takes over, in Laity Moor or wherever in Cornwall.
