AdBlue in the Diesel Tank in Church Field? Keep It Switched Off

AdBlue in your diesel tank? Then leave the motor off — and the ignition as well. In plain terms, AdBlue is just urea in water. Unlike fuel, it neither ignites nor blends, and no harm starts until the motor sucks it through. In Church Field, AdBlue in a diesel tank found before the motor runs normally comes down to a drain and a thorough flush, just where the car is. Call 0333 366 0103 before you do anything else.

Those opening minutes: AdBlue in the diesel tank around Church Field

Things to do:

  • Take the keys out, and so no one switches the ignition on.
  • Close to moving traffic? Then put the hazards on.
  • Which fluid, and roughly what volume? Hang on to the bottle or the till receipt, and our engineers will see.
  • Ring us from where you are. A postcode starting PE7 1, or the name of the closest street, brings our van to you without a search.

Not to do:

  • Shifting the vehicle even a few yards is no reason to fire up your motor.
  • Do not switch the ignition on. On plenty of diesels that alone runs the fuel pump.
  • No more fuel added. The AdBlue won't mix, so it's pointless.
  • Don't drive it anywhere, not even a short way up Peterborough Road.
  • Do not try to drain the vehicle yourself by the roadside.

Rolling the vehicle away from the pumps is a job for staff to help with, wherever Church Field forecourt you're on, the Esso or any other. Parked on your own drive? Then it remains just where it is.

AdBlue in a diesel tank, and what it does there

Meant for the exhaust, AdBlue has no place in your motor. Its own reservoir keeps it, and from there it is sprayed into the exhaust, and there it cleans the fumes. A fuel pump isn't designed to take it, and AdBlue was never supposed to go through one.

Inside a diesel tank it behaves very differently from fuel. It does not mix in. Denser than diesel, it drops and collects underneath it — the same spot the intake draws from. Once your pump runs, the AdBlue is top of the list to be pulled through. Before then it waits beneath your diesel, and that is why a car topped up in Whittlesey last night and not switched on stays the simple one, provided nobody touches the key.

From there it does two kinds of harm. 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, so it keeps labouring on the components it gets to for as long as it remains there. Lines holding AdBlue mean damage by morning for a vehicle parked in Church Field. Just in that tank, it stays the same. Diesel protects the high-pressure pump and each injector as it flows; water offers no lubrication, which is a second form of harm.

Draining AdBlue from a diesel tank in Church Field

Why AdBlue in a diesel is commonly more significant than petrol

Top up a diesel with petrol in error at the BP, and this problem is thinned fuel. It mixes with the diesel, and while it is in the tank it does no damage; the harm comes from running the engine on it.

AdBlue in a diesel is another matter: not thin fuel, but no fuel at all. Since it doesn't burn, running it through is not an option. Crystals and corrosion stay after the next fill, and AdBlue separates back from the diesel, and so watering it can't work. That is why the flush counts so much, and turning the key "to see" does more harm here than nearly any other slip — in Inhams End or the centre of Church Field equally.

With AdBlue, the good news is no different from petrol. Not run? Then the AdBlue sits just inside that tank, the easiest bit of the entire system to clear, anywhere your car has stopped across Cambridgeshire.

Church Field: how AdBlue ends up in a diesel tank

It is not deliberate. Many cars keep the AdBlue cap beside the diesel inlet, now and then behind one flap, and mixing them up is simple in poor light. Most of the time it takes place with a bottle bought on the way home and poured in on the drive, not at the forecourt.

It tends to happen in a couple of familiar ways. A warning light comes on during the school run, and the top-up happens in a hurry outside Park Lane Primary & Nursery School. Near Holly Blue Gardens, a driver tips a container in on the drive after work. Otherwise, in dim light by The Letter B (BBQs & Brews), your car gets refilled by someone opening that flap the first time.

The least familiar cars see it the most — rentals, new cars, company cars, and the spare vehicle in a home with both fuel types. Anywhere in Cambridgeshire, Church Field included, the mistake does not change, and neither does the first step: leave it off.

AdBlue in your diesel tank in Church Field, and the motor started?

Then your tank is no longer where the AdBlue is. Given any running time, it goes on to the injection pump and every injector, after passing through your filter and lines.

Rough running, smoke from the exhaust, lost power, dashboard warnings or cutting out: each may show up, perhaps part way across Church Field or coming back from Whittlesey Junior Football Club. When safe, pull over and switch it off — with no turning it on again to test. Every start pulls more of it through.

Church Field lies under 10 miles from the A1(M); if you were on it, leave at the first junction and pull up safely instead of driving on.

A quick hop across Church Field to the car park by Whittlesey Salvation Army is one matter; driving towards Peterborough, under 5 miles away, is something else, since each mile carries the AdBlue further in. So distance matters. Let us know about how far it had come.

We do all of the cleaning where your car has ended up, and once the motor has been started there is more of it. Lasting damage is very unusual if it is spotted quickly.

What does an AdBlue drain on a diesel involve in Church Field?

Anywhere it has stopped in Church Field — a filling station, a lay-by, a driveway, a street beside St Andrews — the van travels to the vehicle. What was put in, about the quantity, and whether your motor has turned over: we ask before all else, since those shape the job.

Next, emptying your tank right there removes the contaminated diesel along with the AdBlue together. What remains from AdBlue won't flush out by itself, so the fuel system gets a full flush, which matters much more here than with petrol. Testing the car comes at the end, once clean diesel is added and the filter gets flushed or, if necessary, swapped. If your engine hasn't run, the majority of jobs take about half an hour once we arrive. The pumps are explosion-proof, fine on a busy forecourt and quiet enough to use outside a house after dark.

Lastly, the system is primed with new diesel. You head off as soon as our engineers have started the engine, and it makes no difference whether the vehicle is on a drive around Church Field or in a bay at Whittlesea. We make sure it runs correctly on fresh diesel before we go. We do it all wherever the vehicle has stopped, and it never needs to be taken to a workshop. You get a VAT invoice and an engineer report afterwards, which is what insurers want.

What does AdBlue in a diesel tank cost to sort out around Church Field?

No flat figure could be fair, because each job differs. Whether the motor has been running, and for how long, comes first in what changes the price. How much AdBlue went in comes next, and then the position of the vehicle, since an open drive is simpler for our van to get to safely than a tight space behind Whittlesey Christian Church.

What was put in, what quantity, and if the engine ran: each Church Field call begins with exactly that, before any figure, not afterwards. Once those are answered, a range turns into one firm number.

Before anyone heads out, you are told our price by phone. Then you pay on the day, card or by phone, with nothing in advance. As our engineer is travelling, check your policy: plenty include misfuelling.
