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

AdBlue in your diesel tank? Then leave your engine off — and your ignition too. Water with urea mixed in it: that's AdBlue. As it is water-based, it won't ignite and won't blend with diesel; trouble just comes when the pump starts drawing it. Caught before your motor has run, AdBlue in a diesel tank is generally a drain and a thorough flush, done where the car is in Cowfold. Before anything, ring us on 0333 366 0103.

What to do straight away, Cowfold: AdBlue in the diesel tank

Do these:

  • Pocket your keys, and that prevents someone turning the power on.
  • Hazards on, if moving traffic is anywhere near.
  • Which fluid, and about how much quantity? Save the bottle or your receipt, and our technicians can see.
  • Our van locates you quickest with a postcode starting RH13 8, or simply the name of a street close by, so call from the spot.

Never:

  • Not even briefly, and not to roll the car: the engine stays off.
  • Don't switch your ignition on. On plenty of diesels that alone runs the fuel pump.
  • No more fuel added. The AdBlue will not blend, so it is pointless.
  • Don't drive the vehicle anywhere, not even a short stretch down The Street.
  • Beside the road, don't try emptying it yourself.

On a forecourt around Cowfold, whether it is the Pretty's Garage or another one, ask the attendants to help you push the vehicle clear of the pump. Parked on your own drive? Then it stays just as it is.

AdBlue in a diesel tank, and what it does there

AdBlue is made for the exhaust, not the motor. Stored in a separate tank, it's squirted into the exhaust stream to clean the fumes. Neither side fits the other: urea doesn't belong in an injection pump, and an injection pump can't take urea.

Poured in with your diesel, it keeps separate instead of blending — entirely different from fuel. The pickup takes fuel from the lowest part of the tank, and that's just where AdBlue ends up: as it is denser than diesel, it sinks. Easiest of all: one that got AdBlue in Maplehurst overnight and hasn't been started since. The AdBlue waits at the base of that tank, undrawn — though it would be first through if the motor runs, before any diesel at all.

It causes two kinds of harm from there. It attacks certain metals found in fuel systems, working on any part it reaches till it is cleared completely. And when the water evaporates, the urea forms crystals that clog filters and lodge in tiny passages. A motor left sitting around Cowfold with AdBlue already in its lines is worse by the morning; one with AdBlue only in its tank isn't. Water lubricates nothing. The high-pressure pump and every injector need diesel flowing past them, so the water content harms them in its own right.

Draining AdBlue from a diesel tank in Cowfold

Petrol or AdBlue in a diesel: why AdBlue is commonly worse

Petrol pumped into a diesel on Merco's forecourt makes your fuel thin — that's the main issue. No damage is done as long as it sits put, mixed into your diesel — only when the motor runs on it.

The issue with AdBlue in a diesel is a completely wrong substance. Not burning, it can't just be run through. Nor can it be thinned, since it separates again — and the following fill won't clear away crystals or corrosion. So the flush counts more here, and trying the engine "to see", in the heart of Cowfold or out in Shermanbury, does more harm than nearly any other mistake.

As with petrol, there is good news. Not started? Then the AdBlue sits just inside that tank, the easiest section of the entire system to empty, anywhere your car has come to rest in West Sussex.

How does AdBlue end up in a diesel tank around Cowfold?

Plenty of motors place the AdBlue filler beside the diesel cap, occasionally under a single flap, and in dim light the two may appear identical. No one intends it. A bottle bought when driving home and tipped in outside the house, rather than at the filling station, is the typical story.

A few familiar ways cover most cases. Halfway through the morning drop-off, the dashboard flags it up, and outside St Peter's CofE (Aided) Primary School the refill is hurried. Close to Henfield Road, a driver pours a container in on that drive in the evening. Or your car is topped up in the car park outside Hare & Hounds, in poor light, by someone who has never opened that flap before.

The least known cars get it the most — hire cars, brand-new ones, company cars, and the other vehicle in a family with both fuel types. Anywhere in West Sussex, Cowfold included, the slip doesn't change, and nor does the first response: leave it switched off.

Cowfold: started the engine with AdBlue in your diesel tank?

Then the AdBlue has left that tank. Through your filter, through the pipework, and — with any running time — on to the high-pressure pump and every injector: that's where it travels.

You may notice your motor running unevenly, smoking, losing power, showing warning lights or cutting out, perhaps on the way back from Eastlands Wood or halfway across Cowfold. Stop when it is safe. Switch off. Leave the vehicle off rather than restarting it to check. More of that is pulled through with each start.

If you were on the M23, under 10 miles from Cowfold, come off at the next exit and stop somewhere safe rather than pressing on.

Every mile pushes the AdBlue deeper into your system. That's why a hop across Cowfold to park beside Cowfold Village Hall and a drive of under 15 miles for Brighton and Hove are very separate jobs. Tell us roughly how far it had come.

There is more to flush once the engine has been run, and our technicians do all of it where the vehicle has come to a stop. If it's noticed soon, long-term damage is very uncommon.

What emptying AdBlue from a diesel involves around Cowfold

A street by Saint Peter's Church, a driveway, a layby or a filling station: anywhere your car has come to rest in Cowfold, our technicians travel to it. What went in, roughly how much, plus if the engine has been run: our engineers ask first, because those decide the job.

The contaminated diesel and the urea leave together when the tank is emptied, right there. Residue from AdBlue will not wash out by itself, so the whole system gets a careful flush, which counts far more here than with petrol. Next, the fuel filter: flushed, or changed if it has to be. After that clean diesel, and then a check of the car. Most of these jobs are a half-hour job once we arrive, provided the engine hasn't run. Low-noise enough to use outside a house at night, and safe on a working forecourt, the pumps are explosion-proof.

Clean diesel goes in to prime your system, and that's the last step. Whether it's a parking space outside Horsham or a driveway in Cowfold, that is where our technicians start the engine and you set off. Our technicians confirm it runs smoothly on clean diesel before we go. As the job is done in full where the car is, a workshop never comes into it. You get a VAT invoice and an engineer report later, which is what insurers ask for.

AdBlue drains around Cowfold and across West Sussex

AdBlue jobs around Cowfold go to vans that cover the towns around it — Kent Street, Crabtree as well as Littleworth — and much of West Sussex beyond, throughout RH postcodes. Phone and ask instead of guessing if you are by a border, or somewhere awkward to pin down.

A van that comes to you suits Cowfold, a village: you have no need to take the vehicle to us, since our technicians empty it on the spot, on a driveway, a side street, a car park or a forecourt.

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

Each job is different, so no fixed price would be fair. What changes the cost is, first of all, whether the motor has run and for how long; then how much AdBlue was put in; and finally where the car is and whether a van can reach it safely, which is easier on an open driveway than in a tight gap behind St. Hugh's Church.

That's why every call from Cowfold starts with the same three questions, asked before giving a figure, not after: what was put in, how much, and whether it's run. With them, the range narrows to a single firm figure.

Before a van sets off, you hear our price by phone. Then you pay on the day, by card or over the phone, with nothing in advance. Check your insurance whilst we are on the way: many include misfuelling cover.
