Don't Start It: AdBlue in a Diesel Tank in Hillside

If AdBlue has got into your diesel tank, keep your motor off then leave your ignition off. In plain terms, AdBlue is just urea in water. Being water-based, it will not burn and never combines with diesel; damage just comes when the pump starts pulling it. A drain and a thorough flush, done where your car is around Hillside, is generally what AdBlue in a diesel tank needs — if it's caught before the engine has been run. Before anything, call us on 0333 366 0103.

AdBlue in your diesel tank around Hillside: the first few minutes

Do these:

  • Keys out — that way no one can power anything on.
  • Hazards on, if moving traffic is at all close.
  • Hold on to your receipt or the empty bottle, so you can tell us what was put in and about how much.
  • Call right where you are. Say a BA2 8 postcode or the nearest street sign, and no one has to hunt for you.

Not to do:

  • Do not start your motor, even for a moment to shift your car.
  • Don't switch your ignition on. On many diesels that alone runs the fuel pump.
  • No extra fuel on top. The AdBlue will not blend, and so it's wasted.
  • Even a short stretch along Keel's Hill is too far to drive the car.
  • No emptying it yourself, at all, at the verge.

The attendants on duty at any Hillside forecourt — the Murco among them — will normally lend a hand rolling it clear if you ask. At home, the car remains just as it is.

AdBlue in a diesel tank, and what it does there

AdBlue is made for your exhaust, not your engine. Its own reservoir holds it, and from there it is fed into your exhaust, where it cleans the gas. Not one side suits the other: urea doesn't belong in an injection pump, and a pump can't deal with urea.

It doesn't blend. Once it's tipped into the tank, AdBlue acts nothing like fuel. The pickup takes fuel from the lowest part of your tank, and that is exactly where AdBlue ends up: as it is denser than diesel, it sinks. Once your system runs, the AdBlue is first to be pulled through. Before then it sits underneath your diesel, and that is how a car filled in Ashgrove yesterday and never switched on stays the simple one, provided no one touches the key.

It does two kinds of harm from there. Crystals and corrosion. As the water evaporates, it leaves urea that hardens in filters and narrow passages; meanwhile, because it attacks certain metals, every part it touches suffers for as long as it stays inside. By daybreak, a car sitting in Hillside with AdBlue through its pipework gets worse; where it is only in that tank, nothing changes. The water in it does harm of its own: the high-pressure pump and the injectors depend on diesel to lubricate them, and water gives them nothing.

Draining AdBlue from a diesel tank in Hillside

AdBlue in a diesel: why it's regularly worse than petrol

Petrol pumped into a diesel on Shell's forecourt makes your fuel thin — that is the whole issue. Blended into your diesel and left unused, it is harmless for now; using the motor does the harm.

The trouble with AdBlue in a diesel is a totally unsuitable liquid. Not burning, it can't simply be run through. Crystals and corrosion stay after the following tankful, and AdBlue separates again from the diesel, so thinning it won't help. Hence the flush matters so much, and trying the engine "to see" does more harm with AdBlue than almost any other mistake — in Wicklane or the heart of Hillside alike.

As with petrol, there's good news. Not run? Then the AdBlue sits just inside that tank, the simplest section of the whole system to clear, wherever your car has come to rest around Somerset.

Hillside: how AdBlue ends up in a diesel tank

Nobody means to do it. The AdBlue filler on many vehicles waits right next to the diesel filler, sometimes under the same flap, and the two caps can look alike in poor light. A bottle picked up when driving home and poured in at home, instead of at the filling station, is the usual story.

A few familiar ways account for the majority of them. Rushing, outside Peasedown St John Primary School, after a warning light flashed on during the school run, someone refills the vehicle. A bottle is poured in at the end of the day on a drive just off Hillside View. Or the car is topped up in the car park outside Wagon and Horses, in poor light, by somebody who has never opened that flap before.

Rented vehicles, new motors, company motors, or the second car in a home with one of each: the least familiar cars see it the most. Anywhere around Somerset, Hillside included, the mistake doesn't change, and neither does the first step: keep it switched off.

AdBlue in the diesel tank around Hillside, and the motor started?

Then that tank is no longer where the AdBlue is. It's been sucked through your filter and the fuel lines, and if your motor ran for any time, it has reached your high-pressure pump and the fuel injectors.

Maybe coming back from Sprickles, or midway across Hillside, your motor might run rough, smoke, drop pace, light up the dash or stall. No starting it again to test: pull over once safe, then switch it off. Each start pulls more of that through.

Hillside lies under 15 miles from the M32; if you were on it, exit at the first junction and stop safely rather than carrying on.

Every mile carries the AdBlue deeper into the system. That's why a hop across Hillside to park near Peasedown St John Methodist Church and a drive of under 10 miles for Bath are very separate jobs. Let us know about how far it had come.

Once your engine has been run, the flush takes in more, and all of it is done where your car has come to a stop. Very seldom does it leave permanent damage when it's caught early.

What emptying AdBlue from a diesel involves in Hillside

The car stays put, whether that is a road near St John the Baptist, a drive, a lay-by or a filling station in Hillside, and the van comes to it. What went in, about how much, and if the motor has been run: our engineers ask first, since those shape the job.

Then that tank is drained where the vehicle stands, and so the contaminated fuel and the AdBlue come out together. A careful flush matters far more with AdBlue than with petrol, because what remains will not wash out by itself. Fresh diesel goes in after your filter is cleaned — or swapped, when it needs to be — and then the car is tested. About half an hour on site is usual for most jobs where your motor has not run. The pumps are explosion-proof, fine on a busy forecourt and quiet enough to use outside a house after dark.

Clean diesel goes in to prime the system, and that's the final step. At that point our technicians fire it up and you set off, whether from a parking space outside Oldfield Park or a driveway around Hillside. It is tested on clean diesel to make sure it runs properly before our technicians head off. As the job is done in its entirety where the car is, a garage never comes into it. Insurers want a VAT invoice and an engineer report, and you get both at the end.

Hillside and Somerset: AdBlue drains across the area

Lower Peasedown, Peasedown St John and Carlingcott are among the places near Hillside that the same teams serve, along with most of Somerset beyond, throughout the BA postcode area. Close to a border, or somewhere tricky to pin down? Checking is better than assuming, and so ring.

No moving is needed. In Hillside, a residential suburb, a van that comes to you fits: the car is emptied where it stands, be it on a drive, a side street, a car park or a forecourt.

What AdBlue in a diesel tank costs to put right around Hillside

There's no honest single price, since the jobs aren't the same. Three things shift the price: whether the engine has been running and for how long, how much AdBlue got in, and where the car is. That last one turns on whether a technician can reach it safely, and an open driveway is easier than a tight gap behind Peasedown St John Christadelphian Hall.

With that in mind, every enquiry from Hillside begins with the identical trio — which fluid got in, how much, whether it ran — ahead of any figure. The replies turn a range into a straight price.

Before anyone sets off, you are told the price by phone. Then payment is on the day, card or by phone, with nothing upfront. Misfuelling cover is part of many insurance policies, so it pays to look at yours before the van arrives.

Next to your car in Hillside, still?
