AdBlue in a Diesel Tank in Row? Don't Start It
If AdBlue has got into your diesel tank, leave the motor off and keep the ignition off. AdBlue is urea mixed in water. It doesn't burn, it doesn't mix with diesel, and the harm it does begins when the fuel system pulls it in. If the engine has not run yet, AdBlue in a diesel tank is normally drained and thoroughly rinsed where your car stands around Row. Nothing comes before calling 0333 366 0103.
Row, AdBlue in your diesel tank: what to do at once
Things to do:
- Take the keys out, and so no one switches the ignition on.
- Hazards on, if moving traffic is anywhere close.
- Keep the receipt or the empty bottle, and so you can tell us what got in and roughly how much.
- Tell us a postcode starting CA10 1, or whichever street lies nearest, and our van reaches you straight — so ring wherever you stand.
Things not to do:
- Shifting your car just a few yards is no reason to fire up your engine.
- Plenty of diesels run their fuel pump the moment your ignition goes on, so leave it off.
- Pouring in extra diesel doesn't help: AdBlue separates out instead of thinning.
- Even a short distance down Currah Close is too far to drive the vehicle.
- No emptying it yourself, at all, on the roadside.
On a forecourt in Row, whether it is the the nearest petrol station or another one, ask the attendants to help you push the vehicle away from the petrol pump. On that drive, the car stays just where it was left.
AdBlue in a diesel tank: what it does
Meant for the exhaust, AdBlue has no place in your motor. Stored in a separate tank, it's injected into the exhaust stream to treat the gases. Neither side suits the other: urea doesn't belong in an injection pump, and an injection pump can't deal with urea.
Inside a diesel tank it acts really differently from fuel. It doesn't mix in. It sinks, because it's denser than diesel, and pools low where the pickup takes its supply from. Simplest of all: a vehicle that got AdBlue in Shire overnight and hasn't been started since. The AdBlue sits at the foot of the tank, undrawn — but it would be the first thing through once your motor runs, before any diesel at all.
After it's pulled in, the harm comes in two forms. Crystals and corrosion. As the water evaporates, it leaves urea that hardens in filter elements and narrow passages; meanwhile, because it attacks certain metals, every part it touches keeps suffering for as long as it remains inside. Overnight, a car parked in Row with AdBlue in its lines grows worse; if it's just inside your tank, it doesn't. Water lubricates nothing. The injection pump and each injector depend on diesel flowing through them, and so the water content damages them in its own right.
Why is AdBlue in a diesel regularly the bigger fault?
Petrol put into a diesel on another forecourt nearby's forecourt makes the fuel watery — that's the whole fault. No damage is done as long as it sits unused, mixed into the diesel — only when the engine works on it.
AdBlue in a diesel is a fault of the wrong substance altogether. It does not burn, so it can't simply be run through. Crystals and corrosion remain after the next tankful, and AdBlue separates again from the diesel, so watering it can't work. That is why the flush matters so much, and turning the key "to see" costs more with AdBlue than almost any other slip — in Crewgarth or the heart of Row equally.
The same good news holds as with petrol. Wherever in Cumbria the car has come to rest, an unstarted motor leaves the AdBlue still inside the reservoir: the simplest part of a fuel system to clear.
Row: how AdBlue ends up in a diesel tank
Plenty of motors put the AdBlue filler alongside the diesel one, now and then behind one flap, and in dim light the two may look the same. Nobody means it. Mostly it is not the forecourt: a driver picks up a bottle driving home and pours it in at home.
Mostly, it occurs in one of a few familiar ways. The top-up is rushed outside Culgaith CofE School, because the dash lit up with a warning while the children were taken off. A bottle is poured in at the end of the day on a drive just off Ullesby Gardens. Or a driver new to that flap tops up the vehicle in dim light, parked in the car park outside The Fox.
It crops up most in a hire car, a brand-new motor, a fleet vehicle, or the other motor in a family with both fuels — the cars people use the least. Same slip, same first step — leave it switched off — anywhere you are around Row or the remainder of Cumbria.
AdBlue in the diesel tank in Row, and the engine started?
In that case, the AdBlue is no longer inside the tank. Via your filter, through the lines, and — with any running time — into the high-pressure pump and every injector: that is where it travels.
Lumpy running, smoke from the exhaust, dropping power, dashboard lights or stalling: each might show up, perhaps midway across Row or returning from Gillbank Wood. No restarting to check: stop once it is safe, then turn it off. Every start pulls more of it through.
If you were on the M6, under 10 miles from Row, come off at the next junction and stop somewhere sensible instead of pressing on.
Each mile carries the AdBlue further in. That is why crossing Row to park near St Luke and a drive of under 25 miles towards Carlisle are such separate jobs. Roughly how far had it come? Tell us.
Once the engine has been run, the flush covers more, and all of it is done where the vehicle has ended up. Permanent damage is very unusual when it's spotted early.
What draining AdBlue from a diesel involves in Row
The car remains put, whether that is a street near fort, a drive, a lay-by or a filling station around Row, and the van travels to it. Three replies decide the job, so before anything else our technicians ask what went in, roughly what quantity, plus if your motor has turned over.
Then that tank is drained where your car waits, so the tainted fuel and the AdBlue come out together. With AdBlue, more so than with petrol, flushing counts: the whole system is flushed right through because residue will not flush out by itself. Next, the fuel filter: cleaned, or changed if it must be. After that fresh diesel, then a check of the vehicle. Engine not run? Then count on about half an hour once we are there for most jobs. The pumps are explosion-proof, fine on a busy forecourt and quiet enough to use outside a house at night.
Bleeding the system with fresh diesel comes last. Whether it is a parking bay at Langwathby or a drive around Row, that is where we start the engine and you drive off. It is checked on new diesel to confirm it runs correctly before we go. As the job is done in its entirety where the car is, a workshop never comes into it. You get a VAT invoice and an engineer report later, which is what insurers want.
About Row
Row is a small suburban area situated on the riverside in Cumbria, with a mix of detached housing and a population of around 502 residents. Row sits at an elevation of 201 metres, near the villages of Ousby, Bradley, and Hole, and is located approximately 19 miles from Carlisle. Row is part of the wider North West region, and is about 243 miles from London.
AdBlue drains across Row and Cumbria
Ousby, Bradley and Hole are among the towns around Row that the same vans serve, along with most of Cumbria further out, over the CA postcode area. Assuming won't help by a county line or anywhere hard to pin down; ring and ask.
No towing is needed. In Row, a residential suburb, a mobile service fits: your vehicle is drained on the spot, whether in a drive, a residential street, a parking area or a forecourt.
AdBlue in a diesel tank around Row: the cost of fixing it
Since each callouts vary, a single figure would not be honest. Three things move the price: whether the engine has been running and for how long, how much AdBlue got in, and where your car is. That last one comes down to whether a van can get to it safely, and an open driveway is simpler than a tight space behind St John the Evangelist.
That's why each call from Row starts with the same three questions, asked before giving a figure, not after: what went in, how much, and if it has run. Once those are known, a range turns into one fixed figure.
The price is quoted during the call, before a van sets off; settling up comes on the day, by card or by phone, with nothing upfront. Many insurance policies include misfuelling cover, so it's worth checking yours whilst we're on the way.
Row: still alongside your car?
Then, the most helpful thing to do with your vehicle is to leave it. Ignition off, motor off, keys out. Phone 0333 366 0103: AdBlue, roughly how much, plus whether the engine ran is all we need. Petrol in Diesel handles the rest across Cumbria, Row too.
