Blackheath: AdBlue in the Diesel Tank? Leave It Off

If AdBlue has gone into the diesel tank, keep your engine off and keep your ignition off. In plain terms, AdBlue is simply urea in water. As it is water-based, it will not ignite and never combines with diesel; trouble just comes once the pump starts pulling it. A drain and a thorough flush, done where the vehicle is in Blackheath, is usually all AdBlue in a diesel tank needs — if it's caught before your motor has run. First, phone us on 0333 366 0103.

Your next steps right now, Blackheath: AdBlue in the diesel tank

Things to do:

  • So nobody can turn the ignition on, take your keys out.
  • Close to moving traffic? So put the hazards on.
  • Keep the till receipt or the empty bottle, and so you can tell us what got in and roughly how much.
  • The van finds you fastest with a postcode starting CO2 0, or just the name of a street close by, and so call from the spot.

Things not to do:

  • Not even for a second, and not to shift your car: your motor stays off.
  • Many diesels run their pump the instant the ignition goes on, so keep it off.
  • No more fuel added. The AdBlue won't mix, so it's wasted.
  • Even a short way up Blackheath is too far to drive the car.
  • Emptying your tank yourself beside the road is not one to try.

Get the attendants to help you roll the car away from the island if you are on a forecourt around Blackheath, whether it's the BP or elsewhere. At home, your car remains exactly where it is.

What AdBlue does in a diesel tank

Not the engine but the exhaust is where AdBlue belongs. It goes into its own tank and is sprayed into the exhaust gas to clean it. A fuel pump is not made to take it, and AdBlue was never supposed to travel through one.

It doesn't combine. Once it is tipped into a tank of diesel, AdBlue behaves not at all like fuel. It's heavier than diesel, so it sinks and collects at the bottom of your tank, which is where the pickup sucks fuel from. Easiest of all: one that got AdBlue in Rowhedge overnight and has not turned since. The AdBlue sits at the base of that tank, undrawn — though it will be first through once the motor runs, ahead of any diesel at all.

It does two kinds of harm from there. It eats at certain metals found in fuel systems, working on any part it reaches until it is removed completely. And when the water goes, the urea forms crystals that clog filters and lodge in narrow channels. Lines carrying AdBlue mean damage by morning for a car sitting in Blackheath. Only inside that tank, it stays the same. Diesel protects the injection pump and each injector as it passes; water gives none of that, which is a separate kind of harm.

Draining AdBlue from a diesel tank in Blackheath

Why is AdBlue in a diesel commonly the bigger fault?

A fault of thin fuel is what you end up with after filling a diesel with petrol at the Murco. No harm comes as long as it sits put, blended into your diesel — only when your motor works on it.

AdBlue in a diesel is a fault of the wrong substance altogether. It does not burn, so it can't just be run through. Nor can it be watered down, because it splits back out — and the following fill won't clear away crystals or corrosion. So the flush matters for more here, and turning the key "to see", in the heart of Blackheath or out in Abberton, does more harm than nearly any other error.

As with petrol, there is good news. Clearing a tank is the simplest part on a fuel system, and with no start-up, the AdBlue stays in there — anywhere in Essex the vehicle has stopped.

How does AdBlue end up in a diesel tank in Blackheath?

After dark, two caps together — the AdBlue one and the diesel cap, now and then under one flap — may appear the same. Nobody intends it; many designs invite it. It usually occurs outside the house, from a bottle bought en route home, rather than at the filling station.

A couple of familiar ways cover the majority of them. Hurrying, outside Cherry Tree Academy, after a warning lamp flashed on during the school run, a parent refills the vehicle. A bottle is poured in at the end of the day on a drive just off Gosfield Road. Or a driver unfamiliar with that flap tops up your car in dim light, stopped in the car park outside The Cherry Tree.

The least known cars get it the most — rentals, new ones, fleet ones, and the other motor of a home with both fuel types. Leave it switched off: that is the first response to the same slip, anywhere in Blackheath or the remainder of Essex you happen to be.

Started the motor with AdBlue in the diesel tank in Blackheath?

Then the AdBlue has left your tank. It has been sucked through the fuel filter and the fuel lines, and if the engine ran for any time, it has reached your high-pressure pump and the injectors.

Maybe coming back from Corporal Budd VC Gymnasium, or midway across Blackheath, the motor may run lumpy, smoke, lose power, light up the dash or cut out. No starting it again to check: stop when it is safe, then switch it off. Each start pulls more of it through.

Blackheath lies under 50 miles from the M11; if you were on it, exit by the first junction and stop safely instead of driving on.

Mileage matters: every mile pushes the AdBlue further in, and so heading for Colchester, under 3 miles away, makes a much larger job than hopping across Blackheath to the car park by Orchard Baptist Church. Let us know about how far it had come.

We do all of the rinsing where the car has come to a stop, and once your engine has run there is more of it. Spotted soon, it very rarely leaves lasting damage.

What emptying AdBlue from a diesel involves in Blackheath

Our engineers come to the car, wherever it has stopped in Blackheath: a side street near St Margaret's Church, a drive, a lay-by or a forecourt. What got in, roughly the quantity, and whether the engine has turned over: we check first, because those decide the work.

The contaminated diesel and the urea leave as one after that tank is emptied, right there. The fuel system is rinsed thoroughly, which matters more with AdBlue than with petrol, since what it leaves behind does not rinse out on its own. Next, your filter: flushed, or replaced when it has to be. Then clean diesel, and then a test of the vehicle. Most of these jobs are a half-hour job once our engineers turn up, if the motor has not run. Quiet enough for use outside a house at night, and safe on a working forecourt, the pumps are explosion-proof.

The final step is to prime the system on new diesel. You head off as soon as we have started the car, and it makes no difference whether the car is on a driveway in Blackheath or in a bay by Colchester Town. We make sure it runs smoothly on clean diesel before leaving. No garage is required at any stage, with the whole job done then and there. Your insurer is likely to want an engineer's report and the VAT invoice — both yours once this job is done.

About Blackheath and where it is

Blackheath is a suburban area located near Colchester in Essex, sitting at an elevation of around 35 metres in the inland landscape of eastern England. Blackheath is characterized by its semi-detached housing stock and is situated close to nearby places such as Berechurch and Old Heath. Blackheath has a population of approximately 5299 residents and is part of the wider Colchester urban area. Blackheath is also near The Hythe, a historic area of Colchester.

AdBlue drains across Blackheath and Essex

AdBlue jobs in Blackheath go to teams that serve the towns near it — Berechurch, Old Heath as well as The Hythe — and most of Essex further out, throughout CO postcodes. Phone and check instead of guessing if you are close to a border, or anywhere awkward to pin down.

No moving is needed. In Blackheath, a residential suburb, a mobile service fits: your vehicle is emptied on the spot, whether in a drive, a residential street, a parking area or a filling station.

AdBlue in a diesel tank around Blackheath: the cost of fixing it

There's no honest single price, because the jobs aren't the same. What moves the price is, first, whether your engine has run and for how long; then how much AdBlue got in; and after that where your car is and whether a van can reach it safely, which is easier on an open drive than in a tight spot behind St Margarets, Berechurch.

Which fluid got in, how much, plus if the engine ran: each Blackheath call opens with precisely those, before any figure, never after. Once those are known, a range turns into a single fixed number.

Priced on the call before the van sets out, the job is paid for that day — card or phone, no deposit. Check your insurance whilst we are on the way: plenty include misfuelling cover.

In Blackheath and still alongside the vehicle?

In that case, touch nothing — that's the best move there is. Ignition off, engine off, keys out. Phone 0333 366 0103 and tell us it is AdBlue, roughly how much, and if it has run. Petrol in Diesel takes it from there, around Blackheath or anywhere around Essex.
