AdBlue in a Diesel Tank in Coldeast? Don't Start It
Engine off, ignition off: that is where you begin if AdBlue has gone into the diesel tank. Water with urea mixed in it: that's AdBlue. It doesn't burn, it does not mix with diesel, and the damage it does starts when the fuel system draws it in. In Coldeast, AdBlue in a diesel tank caught before your engine runs normally means a drain and a thorough flush, right where the car is. Call 0333 366 0103 before you do anything else.
Those opening minutes: AdBlue in your diesel tank in Coldeast
Do:
- Keys out — that way nobody can power anything on.
- Hazards on, if moving traffic is anywhere near.
- The empty bottle or the receipt shows us the product and the amount, so don't bin it away.
- Our van finds you fastest with a postcode starting TQ12 6, or just the name of a street nearby, and so phone from the spot.
Not to do:
- Shifting the car even a few yards is no reason to fire up the engine.
- The ignition stays off: on many diesels, turning it on is enough to start your pump.
- Adding more diesel does not work: AdBlue settles out instead of thinning.
- Don't drive it anywhere, not even a short distance up Kittersley Drive.
- Emptying your tank on your own beside the road isn't worth trying.
The staff working at any Coldeast forecourt — the Shell among them — will usually help pushing it clear if you ask. At home, the car remains exactly as it is.
What AdBlue does in a diesel tank
AdBlue is made for your exhaust, not your motor. Kept in a separate tank, it's squirted into the exhaust to treat the fumes. Not one side suits the other: urea doesn't belong in a pump, and an injection pump cannot take urea.
It does not blend. Once it's tipped into the tank, AdBlue behaves not at all like diesel. It is heavier than diesel, and so it sinks and collects at the bottom of the tank, which is where the pickup sucks fuel from. The first thing the system pulls through, once it runs, is the AdBlue. So a car that had AdBlue poured in on a drive in Heathfield last night, and has not been started since, is still the easy case: the AdBlue is lying at the bottom of the tank, and nothing has pulled it in.
It does two kinds of damage from there. What remains once the water evaporates is urea, which turns into crystals: they lodge in tiny channels and block filters. Worse, it attacks some metals in the fuel system, and carries on till it is flushed out. Overnight, a vehicle sitting around Coldeast with AdBlue in its lines grows worse; if it is just inside that tank, nothing changes. Diesel protects the high-pressure pump and every injector as it passes; water gives none of that, which is a second form of damage.
Why AdBlue in a diesel is often more significant than petrol
Top up a diesel with petrol by mistake over at the BP, and this problem is thinned fuel. Harm only comes from driving on it. Blended into your diesel and sitting inside that tank, it causes none.
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. Whether the car sits in South Knighton or the centre of Coldeast, turning it over "to see" does more harm with AdBlue than almost any other slip, and the flush counts more. Why: it will not stay blended, and so watering it down fails; and deposits and corrosion survive the next tankful.
As with petrol, there is good news. Clearing a tank is the simplest part on a fuel system, and with no running, the AdBlue stays in there — wherever around Devon the vehicle has stopped.
How AdBlue ends up in a diesel tank around Coldeast
After dark, two caps side by side — the AdBlue cap and the diesel cap, now and then behind one flap — can look the same. No one means it; many layouts invite it. Usually it is not the forecourt: a driver picks up a bottle driving home and tips it in outside the house.
Mostly, it occurs in one of a few familiar ways. The refill is hurried outside Blackpool Church of England Primary School, after your dash flashed with a warning while the children were dropped in. A bottle is poured in at the end of the day on a drive just off Benedicts Road. One more version: dim light, a pub car park by Star Inn, and a driver using that flap the first time.
The least familiar vehicles see it most — rentals, brand-new cars, fleet ones, and the other motor in a home with both fuels. An identical slip, same first step — keep it switched off — wherever you happen to be in Coldeast or the rest of Devon.
AdBlue in your diesel tank in Coldeast, and the engine started?
Then that tank is no longer where the AdBlue is. The fuel filter and pipework have had it pulled through, and any running time carries it on to the injection pump and each injector.
You may see the motor running unevenly, smoking, losing power, showing warning lights or cutting out, perhaps on the way back from Little Meadow or halfway across Coldeast. Pull over when it is safe. Switch off. Leave it off instead of testing it again. More of that is pulled through with each start.
Coldeast lies under 15 miles from the M5; if you were on it, exit by the next junction and pull up safely instead of driving on.
Each mile carries the AdBlue further into the system. That is why crossing Coldeast to park beside Trago Mills and a drive of under 15 miles towards Exeter are very different jobs. Let us know roughly how far it had come.
Once the engine has been started, the flush includes more, and all of it is done where the vehicle has come to a stop. Very rarely does it leave long-term damage when it is noticed soon.
What does an AdBlue drain on a diesel involve in Coldeast?
Our engineers come to the car, wherever it has stopped around Coldeast: a side street close to Trago Family Fun Park, a drive, a lay-by or a forecourt. The job rests on three answers, which our engineers get first — what was put in, the amount, and whether the motor has turned over.
The contaminated diesel and the urea come out together after that tank is emptied, right there. With AdBlue, far more than with petrol, flushing matters: the whole system is flushed right through since residue will not flush away by itself. Next, the fuel filter: flushed, or replaced when it must be. After that clean diesel, and then a check of the car. About half an hour on site is typical for most jobs when the engine has not run. The pumps are explosion-proof, safe on a busy forecourt and quiet enough to use outside a house at night.
Priming the fuel system with clean diesel comes last. You drive off as soon as our engineers have started the car, and it makes no difference whether your car is on a drive around Coldeast or in a bay by Newton Abbot. It's checked on new diesel to be sure it runs smoothly before our engineers head off. The entire job is done where the car is, so it never has to go to a workshop. Your insurer is likely to want an engineer's report and your VAT invoice — each handed over afterwards.

AdBlue in a diesel tank in Coldeast: the cost of fixing it
Since the jobs vary, a single figure wouldn't be honest. What moves the price is, firstly, whether the engine has been running and for how long; then how much AdBlue got in; and then where your car is and whether a van can reach it safely, which is simpler on an open driveway than in a tight spot behind Super Skate Zone.
What got in, how much, and whether it ran: each Coldeast call opens with precisely those, before any quote, not afterwards. Those answers turn a range into a straight price.
Before a van sets off, you are told the quote on the phone. Then you pay on the day, card or over the phone, with nothing in advance. Check your policy while we're on the way: many include misfuelling cover.
