AdBlue in a Diesel Tank in Preston? Don't Start It
With AdBlue in your diesel tank, your ignition remains off and so does the motor. AdBlue is urea dissolved in water. The trouble starts once it is pulled through your lines — it will not ignite, and it will not combine with diesel. In Preston, AdBlue in a diesel tank found before your engine runs usually means a drain and a thorough flush, right where the car is. No step comes before calling 0333 366 0103.
AdBlue in the diesel tank around Preston: the first few minutes
Things to do:
- Pocket your keys, which prevents someone switching the electrics on.
- Put the hazards on if you are anywhere near moving traffic.
- The empty bottle or the till receipt shows us the product and the quantity, so don't bin it out.
- Ring just where you are. Say a TQ3 2 postcode or the nearest street sign, and no one has to hunt for you.
Never:
- No starting the motor — not briefly, not to reposition the car.
- Turning the key to ignition alone sets the pump going on plenty of diesels. Avoid it.
- No more fuel on top. The AdBlue won't blend, so it's pointless.
- Even a short distance up Wills Avenue is too far to drive the vehicle.
- By the road, don't try draining it yourself.
Rolling your vehicle off the pumps is a job for staff to help with, whichever Preston forecourt you're on, the Shell included. At your own drive, don't touch it at all.
What AdBlue does in a diesel tank
The motor is not what AdBlue is made for; the exhaust is. It goes into its own tank and is sprayed into the exhaust gas to fresh it. A fuel pump is not made 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. It's heavier than diesel, so it sinks and gathers at the bottom of that tank, which is where the pickup pulls fuel from. A vehicle topped up on a driveway in Livermead overnight and not started since is the straightforward case. No pump has sucked the AdBlue up yet — though once your engine runs, that's what is pulled first, straight from the bottom of that tank.
Once it is pulled in, the damage comes in two forms. What remains once the water evaporates is urea, which turns into crystals: they lodge in narrow passages and clog filters. On top of that, it eats at certain metals in a fuel system, and keeps going until it's flushed out. Lines carrying AdBlue mean harm by morning for a vehicle parked around Preston. Only inside your tank, it stays the same. And there's the water: it offers no lubrication to the parts that need it most — the injection pump and each injector.
AdBlue in a diesel: why it's commonly worse than petrol
Petrol pumped into a diesel on Texaco's forecourt makes your fuel thin — that is the whole fault. It mixes with your diesel, and while it's in the tank it does no harm; the harm comes from running the engine on it.
AdBlue in a diesel is a fault of the wrong substance altogether. Because it doesn't burn, running it through is not an option. It does not stay mixed, and so it cannot be diluted. And crystals and corrosion do not wash out with the next tank of fuel. That's why the flush counts more with AdBlue than with petrol, and why starting your engine "to see" costs more here than nearly anywhere else, whether the car is in Paignton or the middle of Preston.
As with petrol, there's good news. Never run? Then the AdBlue sits just inside the tank, the simplest section of the whole system to empty, wherever the car has come to rest across Devon.
How does AdBlue end up in a diesel tank around Preston?
In dim light, two caps side by side — the AdBlue one and the diesel one, occasionally under one flap — can appear the same. Nobody means it; many layouts allow it. A container bought while driving home and tipped in at home, instead of at the filling station, is the typical route.
It tends to occur in a few familiar ways. The refill gets rushed outside Preston Primary School, because your dash lit up with a warning while the kids were taken off. In the evening, a bottle is tipped in on a drive close to Coombe Road. Or the car is topped up in the car park at The Old Manor Inn, in poor light, by someone who has never opened that flap before.
The least known cars get it most — rentals, brand-new cars, company cars, and the spare car in a family with one of each fuel types. Leave it off: that's the first response to the same mistake, wherever around Preston or the remainder of Devon you happen to be.
Already started your engine with AdBlue in the diesel tank around Preston?
Then your tank is no longer where the AdBlue is. Given any running, it travels to the injection pump and each injector, after passing through the filter and pipework.
Perhaps returning from Preston Park, or part way across Preston, your engine may go rough, smoke, drop pace, light up the dash or stall. Once you safely can, pull over then switch everything off — without restarting to test. With each start, more of it is pulled through.
Preston sits under 25 miles from the M5; if you were on it, exit by the first junction and stop safely rather than driving on.
Each mile pushes the AdBlue further in. That is why crossing Preston to park beside Paignton SNU Spiritualist Centre and a drive of under 25 miles for Exeter are very separate jobs. Let us know roughly how far it had come.
There's more to clean out once your engine has been started, and we do all of it where the vehicle has ended up. Permanent damage is very rare when it is caught quickly.
What does an AdBlue drain on a diesel involve around Preston?
Our engineers come to your car, wherever it has stopped in Preston: a side street close to St. Paul's Church, a drive, a lay-by or a forecourt. Three replies decide the work, and so before anything else our engineers ask which fluid got in, about the amount, and whether the motor has run.
Right there, that tank is then drained, and all of the polluted diesel and the urea leave at once. The fuel system is purged thoroughly, which counts more with AdBlue than with petrol, since what it leaves behind does not rinse out on its own. Clean diesel goes in after the filter is flushed — or replaced, when it needs to be — and after that the car is tested. Engine not run? In that case count on about half an hour once we are there for most jobs. Quiet enough to use outside a house at night, and fine on a busy forecourt, the pumps are explosion-proof.
Bleeding the system with clean diesel comes last. Firing it up comes next, and then you head off from where your car is parked, by Paignton or on a driveway in Preston. Our technicians check it runs correctly on clean diesel before leaving. No garage is required at any stage, with the entire job done then and there. You receive a VAT invoice and an engineer report later, which is what insurers want.
About Preston and where it is
Preston is a suburban area in Devon, situated on the coast near Torbay and Hollicombe. Preston sits at an elevation of 29 metres, with detached housing being the predominant type of accommodation. Preston is located approximately 19 miles from Exeter and 166 miles from London, making it a popular residential area. Preston benefits from its proximity to the sea and surrounding coastal towns like Shorton.
AdBlue drains across Preston and Devon
Hollicombe, Torbay and Shorton are among the towns near Preston that the same vans reach, together with much of Devon further out, throughout the TQ postcode area. Ring and ask rather than guess when you are by a county line, or anywhere awkward to explain.
Wherever your car sits — a driveway at home, a side street, a car park, a filling station — our engineers empty it on the spot, with no need to bring it to us; that suits Preston, a residential suburb, well.
What does AdBlue in a diesel tank cost to sort out around Preston?
Not one flat figure would be honest, since every job differs. Three things shift the cost: whether your engine has been running and for how long, how much AdBlue was put in, and where your car is. That last one rests on whether our van can reach it safely, and an open drive is simpler than a tight spot behind Oldway Mansion.
With that in mind, every enquiry from Preston begins by asking the same trio — which fluid got in, what quantity, if it ran — before a quote. Those replies turn a range into a straight price.
Before a van heads out, you are told our quote on the phone. And you pay on the day, card or over the phone, with nothing upfront. While our engineer is travelling, dig out your insurance: many cover misfuelling.
In Preston and still alongside your car?
Then the most useful thing you can do is nothing to the car. Keys out, motor off, ignition off. Tell us it was AdBlue, about how big an amount, and whether it ran, on 0333 366 0103. From there Petrol in Diesel handles it, across Preston or wherever within Devon.
