Don't Start It: AdBlue in a Diesel Tank in Carley Hill
If AdBlue has got into the diesel tank, keep the engine off and keep the ignition off. Water with urea dissolved in it: that is AdBlue. The harm starts once it's pulled through the pump — it will not burn, and it will not blend with diesel. If your motor hasn't run yet, AdBlue in a diesel tank is generally emptied and thoroughly cleaned where the vehicle stands in Carley Hill. Ring 0333 366 0103 before you do anything else.
Carley Hill, AdBlue in your diesel tank: what to do straight away
Do:
- Take your keys out, so no one switches the ignition on.
- If you're anywhere close to moving traffic, put the hazards on.
- Which product, and roughly what quantity? Hang on to the bottle or your receipt, and our technicians will know.
- Call us from where you are. A postcode starting SR5 2, or the name of the closest street, brings our van to you without a search.
Things not to do:
- Do not start the motor, even for a moment to move the vehicle.
- Plenty of diesels run their fuel pump the moment the ignition goes on, and so leave it off.
- Adding extra diesel does not work: AdBlue settles out instead of blending.
- Even a short distance down Eyemouth Lane is too far to drive the vehicle.
- No emptying it yourself, either, on the verge.
The staff on duty at any Carley Hill forecourt — the Asda included — will usually help rolling it clear if you ask. Parked on your own driveway? Then it stays exactly as it is.
AdBlue in a diesel tank: what it does
The motor is not what AdBlue is made for; the exhaust is. Its own tank holds it, and from there it's fed into the exhaust, where it treats the fumes. Not one side suits the other: urea doesn't belong in a pump, and a pump can't deal with urea.
Inside a diesel tank it acts very differently from fuel. It doesn't mix in. Heavier than diesel, it drops and pools underneath it — the very spot the intake draws from. When the pump runs, the AdBlue is top of the list to go through. Until then it waits beneath your diesel, which is how a car topped up in Southwick yesterday and not switched on remains the simple case, as long as no one touches your key.
From there it does two kinds of damage. It eats at some metals used in fuel systems, working on whatever it reaches till it's removed from the system. And when the water evaporates, the urea forms crystals that clog filters and settle in narrow passages. Lines holding AdBlue mean damage overnight for a vehicle parked around Carley Hill. Just in the tank, it stays the same. And there is the water: it offers no protection to the components that need it the most — the high-pressure pump and every injector.
Why AdBlue in a diesel is frequently more serious than petrol
Top up a diesel with petrol by mistake at the Sainsbury's, and this issue is diluted fuel. No harm comes as long as it sits put, blended into your diesel — only when the engine works on it.
The issue with AdBlue in a diesel is a totally unsuitable liquid. Not burning, it can't just be run through. Nor can it be thinned, because it separates back out — and the following tankful won't clear away crystals or corrosion. So the flush counts for more with AdBlue, and turning the key "to see", in the heart of Carley Hill or out in Low Southwick, does more harm than nearly any other mistake.
The good news is the same as with petrol. Wherever around Tyne and Wear the vehicle has come to rest, an unstarted motor leaves the AdBlue yet in the reservoir: the simplest bit of a fuel system to empty.
AdBlue in a diesel tank around Carley Hill: how it ends up there
Many vehicles place the AdBlue filler alongside the diesel one, occasionally behind a single flap, and after dark the two may appear identical. Nobody means it. Mostly it's not the forecourt: a driver buys a bottle heading home and tips it in at home.
The ways it happens are few and familiar. Midway through the drop-off, the dashboard flags it up, and outside Southwick Community Primary School the refill is rushed. A bottle is poured in at the end of the day on a drive just off Edinburgh Square. Else, in dim light outside The Grange, the car is refilled by a driver opening that flap the first time.
It comes up most in a rental, a brand-new motor, a fleet motor, or the spare vehicle of a family with both fuel types — the cars drivers know least. An identical slip, an identical first step — leave it off — anywhere you happen to be around Carley Hill or the rest of Tyne and Wear.
Carley Hill: started your engine with AdBlue in the diesel tank?
Then the AdBlue has left the tank. Through the fuel filter, through the lines, and — with any running time — into the high-pressure pump and each injector: that's where it has gone.
Perhaps returning from Carley Hill Quarry (SSSI), or midway across Carley Hill, your motor might go rough, smoke, drop power, flash the dash or stall. Stop as soon as it is safe, switch off, and don't restart the vehicle to check. With each start, more of that is pulled through.
On the A194(M), under 5 miles from Carley Hill, the first junction is where to leave, and somewhere safe is where to park — not driving on.
Mileage matters: each mile pushes the AdBlue further into the system, so driving towards Sunderland, under 3 miles away, makes a much bigger job than hopping across Carley Hill to the car park by Fulwell Acoustic Mirror. Approximately how far had it come? Tell us.
Once the engine has been run, the flush takes in more, and all of it is done where the car has ended up. When it's caught early, lasting damage is very rare.
What clearing AdBlue from a diesel involves around Carley Hill
Anywhere it has come to rest in Carley Hill — a forecourt, a layby, a driveway, a road by Fulwell Windmill visitor centre — our van travels to the vehicle. Three answers decide the job, and so first our engineers ask what got in, about the amount, and if your motor has run.
The contaminated diesel and the urea come out as one when the tank is emptied, on the spot. The fuel system is flushed thoroughly, which matters more with AdBlue than with petrol, since what it leaves behind does not rinse out on its own. Clean diesel goes in after your filter is cleaned — or swapped, if it needs to be — and after that the car is tested. Not run? In that case expect roughly half an hour on site for most jobs. The pumps are explosion-proof, fine on a busy forecourt and quiet enough to use outside a house after dark.
Finally, the fuel system is bled with fresh diesel. Firing it up comes next, and then you head off from where your car is parked, by Seaburn or on a drive around Carley Hill. Our technicians make sure it runs smoothly on fresh diesel before we leave. No workshop is required at any point, with the entire job done then and there. At the end, you are given paperwork for your insurer: a VAT invoice plus a report from the engineer.

Carley Hill: what AdBlue in a diesel tank costs to fix
Every job differs, and so no single quote is honest. Three things shift the cost: whether your engine has run and for how long, how much AdBlue went in, and where the car is. That last one rests on whether our van can get to it safely, and an open drive is easier than a tight space behind Holy Trinity Southwick.
That's why every call from Carley Hill starts with the same three questions, asked before giving a figure, not after: what got in, how much, and whether it has run. Those answers narrow a range right down to a single figure.
Our quote is given during the call, before anyone leaves; settling up happens on the day, by card or by phone, with nothing upfront. Check your policy while we are on the way: plenty carry misfuelling cover.
