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

Engine off, ignition off: that is how you begin if AdBlue has got into the diesel tank. Chemically, AdBlue is just urea in water. The harm starts once it is sucked through your lines — it will not ignite, and it will not combine with diesel. In Arbury, AdBlue in a diesel tank caught before the engine runs usually comes down to a drain and a thorough flush, right where your car is. Call 0333 366 0103 before you do anything else.

Those opening minutes: AdBlue in the diesel tank around Arbury

Do these:

  • So no one can turn the ignition on, take the keys out.
  • Hazards on, if moving traffic is anywhere close.
  • So you can tell us which liquid it was and roughly what quantity, save the till receipt or the empty bottle.
  • Tell us a postcode starting CB4 2, or whatever street lies nearest, and our van finds you directly — so call from wherever you are.

Don't do these:

  • No starting the engine — not briefly, not to reposition your car.
  • Your ignition stays off: on lots of diesels, switching it on is enough to start your fuel pump.
  • No more fuel on top. The AdBlue will not mix, and so it is pointless.
  • Any driving at all is to be avoided, even a short way up Verulam Way.
  • No emptying it yourself, at all, on the verge.

Rolling the vehicle off the island is a job for attendants to help with, whichever Arbury forecourt you are on, the Esso or any other. If you are on your own drive, leave the car just where it stands.

AdBlue in a diesel tank: what it does

Made for your exhaust, AdBlue has no place in your engine. From a dedicated tank it goes directly to the exhaust, cleaning what your motor lets out. A fuel pump isn't designed to take it, and AdBlue was never supposed to travel through one.

Fuel blends; AdBlue, after poured in, will not. Its behaviour is nothing like fuel's. The pickup takes fuel from the lowest part of your tank, and that is precisely where AdBlue ends up: being denser than diesel, it sinks. Simplest of all: one that had AdBlue in Cambridge overnight and hasn't been started since. The liquid waits at the base of that tank, untouched — though it will be first through if your motor starts, ahead of any diesel at all.

Two kinds of damage come from there. What remains when the water goes is urea, which forms crystals: they lodge in narrow channels and clog filters. On top of that, it eats at some metals in the fuel system, and keeps going until it's flushed out. Pipes holding AdBlue spell damage by morning for a car sitting in Arbury. Only inside your tank, it stays stable. Water lubricates nothing. The high-pressure pump and every injector depend on diesel running past them, and so the water content damages them by itself.

Draining AdBlue from a diesel tank in Arbury

AdBlue in a diesel: why it is commonly worse than petrol

An issue of thinned fuel is what you get from filling a diesel with petrol at the BP. Blended into the diesel and left unused, it is harmless at that stage; running the engine does the damage.

AdBlue in a diesel is a different matter: not thin fuel, yet no fuel at all. Since it doesn't burn, running it through isn't an option. Nor can it be thinned, because it splits again — and the following tankful won't rinse away crystals or corrosion. So the flush counts more with AdBlue, and trying your engine "to see", in the centre of Arbury or out in Ridgeway Village, does more harm than almost any other error.

With AdBlue, the good news is no different from petrol. If the motor hasn't run, the AdBlue is still in that tank, and that tank is the quickest part of a fuel system to clear, wherever in Cambridgeshire the car is sitting.

Arbury: how AdBlue ends up in a diesel tank

Plenty of motors place the AdBlue filler beside the diesel cap, now and then under one flap, and in dim light the two can look the same. No one means it. A container picked up when heading home and poured in outside the house, instead of at the forecourt, is the usual story.

A few familiar ways cover the majority of them. The refill is hurried outside Arbury Primary School, because the dash lit up with a warning while the children were dropped off. A bottle is poured in at the end of the day on a drive just off Mere Way. Or someone new to that flap refills the vehicle after dark, stopped in the car park outside The Carlton Arms.

It takes place most in the vehicles drivers know least: a hire car, a new motor, a company car, or the second motor of a household with one diesel and one petrol. Same mistake, an identical first step — keep it switched off — anywhere you are in Arbury or the remainder of Cambridgeshire.

Started the engine with AdBlue in the diesel tank around Arbury?

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

Expect lumpy running, smoke, lost power, lights on the dash, or a cut-out — coming back from St Albans Recreation Ground, say, or midway across Arbury. Stop as soon as it is safe, switch off, and do not restart the vehicle to check. Each start pulls more of that through.

On the M11, under 3 miles from Arbury, the first junction is where to exit, and somewhere safe is where to stop — not driving on.

A quick hop across Arbury to the car park by The Annex - Over 65's Day Centre is one thing; heading towards Cambridge, under 3 miles away, is something else, because every mile carries the AdBlue further in. So distance matters. Tell us about how far it had come.

Once the motor has run, the flush takes in more, and all of it is done where the vehicle has ended up. When it is noticed early, permanent damage is very unusual.

What does an AdBlue drain on a diesel involve around Arbury?

A street by Parish Church of the Good Shepherd Church Hall, a driveway, a lay-by or a forecourt: anywhere your car has stopped around Arbury, we travel to it. The job rests on three replies, which our engineers get first — what got in, the quantity, and if the motor has run.

The polluted diesel and the urea leave as one after that tank is emptied, right there. A full flush counts far more with AdBlue than with petrol, since residue won't wash out by itself. Testing the vehicle comes last, after clean diesel goes in and the filter is flushed or, where necessary, swapped. Roughly half an hour once we arrive is typical for most jobs when your engine has not run. Our pumping gear is explosion-proof, and so a live filling station is no issue, and it's quiet enough for a residential street late at night.

Bleeding your system with fresh diesel comes last. Then we start it and you drive off, whether from a parking bay at Cambridge North or a drive around Arbury. Before we leave, our technicians make sure it's running smoothly with clean diesel in. Our engineers do it all wherever the car has ended up, and it never has to go to a garage. The insurer is likely to want an engineer's report and your VAT invoice — both yours once the job is done.

Arbury and Cambridgeshire: AdBlue drains across the area

Over the CB postcode area, the teams answering AdBlue jobs around Arbury reach most of Cambridgeshire as well, Kings Hedges, Orchard Park and Chesterton included. Assuming won't help close to a border or anywhere tricky to describe; phone and check.

Arbury is a residential suburb, and a call-out drain suits it: whether the vehicle is on a home drive, a residential street, a car park or a forecourt, we drain it where it is, and so it never needs to be shifted to us.

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

There is no honest single price, because the jobs are not the same. Three things shift the price: whether the engine has run and for how long, how much AdBlue got in, and where the car is. That last one comes down to whether a technician can reach it safely, and an open driveway is simpler than a tight space behind Parish Church of the Good Shepherd.

For that in mind, every call from Arbury begins by asking the identical trio — what was put in, what quantity, whether the engine ran — before a quote. Those answers turn a range into a straight price.

Priced by phone before the engineer heads out, the job is settled on the day — card or phone, nothing in advance. While the van is travelling, check your policy: plenty include misfuelling.
