Don't Start It: AdBlue in a Diesel Tank in Cross Stobbs

AdBlue in your diesel tank? Then keep the motor off — and the ignition as well. In plain terms, AdBlue is simply urea in water. The harm starts once it's pulled through your lines — it will not burn, and it won't blend with diesel. Caught before the engine has been run, AdBlue in a diesel tank is normally a drain and a thorough flush, done where your car is in Cross Stobbs. First, call us on 0333 366 0103.

AdBlue in the diesel tank around Cross Stobbs: the first few minutes

Do:

  • So no one can turn the ignition on, take the keys out.
  • If you are anywhere close to moving traffic, put the hazard lights on.
  • Keep the till receipt or the empty bottle, and so you can tell us what went in and roughly how much.
  • Ring just where you are. Quote a G78 1 postcode or the closest street name, and no one has to search for you.

Not to do:

  • Shifting the vehicle even a few yards is no reason to fire up the engine.
  • Your ignition remains off: on lots of diesels, turning it on is enough to start your fuel pump.
  • No extra fuel added. The AdBlue won't mix, and so it is wasted.
  • Any driving at all is to be avoided, even a short way down Stobs Drive.
  • No draining it yourself, at all, on the verge.

The staff on duty at any Cross Stobbs filling station — the Asda among them — will normally help rolling it aside if you ask. At your own drive, do not touch it at all.

AdBlue in a diesel tank: what it does

AdBlue is made for your exhaust, not the motor. Kept in a separate tank, it is squirted into the exhaust to treat the gases. Not one side fits the other: urea does not belong in a pump, and an injection pump cannot take urea.

Inside a diesel tank it acts very differently from fuel. It does not mix in. It sinks, since it is denser than diesel, and settles down where the pickup takes its supply from. A vehicle topped up on a drive in Hillside overnight and not started since counts as the straightforward one. No pump has pulled the AdBlue up so far — though once the engine runs, that is what is pulled first, straight from the bottom of that tank.

It causes two kinds of damage from there. What remains when the water goes is urea, which turns into crystals: they lodge in narrow channels and block filters. On top of that, it eats at certain metals in a fuel system, and keeps going until it is cleared out. Where the AdBlue is in the lines, waiting till morning in Cross Stobbs leaves it worse. In that tank only, waiting does nothing. Then there's the water: it brings no protection to the parts that need it most — the high-pressure pump and each injector.

Draining AdBlue from a diesel tank in Cross Stobbs

Why AdBlue in a diesel is often more major than petrol

A problem of thinned fuel is what you get from fuelling a diesel with petrol from the Barrhead Services. Harm just comes from running on it. Mixed into the diesel and left in your tank, it causes nothing.

With AdBlue in a diesel, the fluid as such is plainly the wrong one. Not burning, it cannot just be run through. It does not stay mixed, and so it can't be weakened. And crystals and corrosion don't wash out with the next tank of fuel. That's why the flush matters more with AdBlue than with petrol, and why starting the motor "to see" costs more here than almost anywhere else, whether the vehicle is in Barrhead or the middle of Cross Stobbs.

With AdBlue, the good news is no separate from petrol. Never started? Then the AdBlue sits only inside that tank, the easiest bit of the entire system to empty, wherever the vehicle has come to rest across Renfrewshire.

How AdBlue ends up in a diesel tank in Cross Stobbs

In dim light, two caps side by side — the AdBlue one and the diesel one, now and then behind a single flap — can appear the same. Nobody means it; plenty of layouts invite it. Mostly it happens with a bottle bought on the way home and poured in on the drive, not at the pump.

A few familiar ways account for most cases. A warning light comes on during the school run, and the top-up happens in a hurry outside the local primary school. A bottle is poured in at the end of the day on a drive just off Leven Court. Another version: darkness, the car park by Cross Stobs Inn, and someone using that flap the first time.

It takes place most in the vehicles people know least: a hire car, a new car, a company car, or the second motor of a household with one diesel and one petrol. Leave it off: that's the first step to an identical mistake, anywhere around Cross Stobbs or the rest of Renfrewshire you happen to be.

Already started the motor with AdBlue in your diesel tank in Cross Stobbs?

The AdBlue has left your tank, then. Given any running, it goes on to the injection pump and every injector, having passed via the filter and pipework.

Watch for lumpy running, smoke, lost power, warnings on the dash, or a stall — returning from Fereneze Golf Club, say, or midway across Cross Stobbs. No starting it again to test: pull over when safe, then turn everything off. With each start, more of that is pulled through.

On the M77, under 3 miles from Cross Stobbs, the next junction is where to exit, and somewhere safe is where to stop — not carrying on.

How far it went counts. A few hundred yards across Cross Stobbs to the car park by Shanks Bowling Club is a very different job from a run towards Glasgow, under 10 miles away, with the AdBlue reaching further into your system with each mile. Tell us roughly how far it had come.

Wherever the vehicle came to a stop is where all of it gets done, even with more to clean out once the engine has been running. Noticed early, it very rarely leaves lasting damage.

Draining AdBlue in a diesel around Cross Stobbs: what it takes

Anywhere it has stopped around Cross Stobbs — a forecourt, a lay-by, a driveway, a street by Dunterlie Park — our van travels to your vehicle. What was put in, about how much, plus if your motor has been run: our engineers check before all else, since those decide the work.

Then that tank is drained where the car waits, and so the polluted fuel and the AdBlue come out together. With AdBlue, far more than with petrol, flushing matters: the whole system is flushed all the way through because what remains won't flush out by itself. Fresh diesel goes in once your filter is flushed — or swapped, when it needs to be — and after that the vehicle is tested. Roughly half an hour once we arrive is typical for most jobs when the engine hasn't run. Low-noise enough to use outside a house at night, and safe on a working forecourt, the pumps are explosion-proof.

Priming your system with clean diesel comes last. You set off as soon as our engineers have fired it up, and it makes no difference whether the car is on a drive in Cross Stobbs or in a space outside Barrhead. It is checked on clean diesel to be sure it runs properly before we leave. No workshop is required at any stage, with the whole job done on the spot. You get a VAT invoice and an engineer report afterwards, which is what insurers ask for.

AdBlue drains in Cross Stobbs and across Renfrewshire

Boylestone, Dunterlie and Crossmill are among the towns around Cross Stobbs that the same vans serve, together with much of Renfrewshire further out, over the G postcode area. If you are close to a border, or somewhere hard to explain, ring and ask rather than guessing.

What does AdBlue in a diesel tank cost to sort out around Cross Stobbs?

There's no honest single price, since the jobs aren't the same. The price shifts first with how long, if at all, your engine has been running, and next with the amount of AdBlue that got in. After that it turns on where your car is and whether our van can get to it safely, which is simpler on an open driveway than in a tight gap behind Dunterlie Community Centre.

Ahead of any figure, never afterwards, every call from Cross Stobbs begins with the same three checks: the fuel, the amount, plus if the engine ran. Once those are answered, a range becomes one fixed number.

Quoted on the call before the van sets out, it is settled that day — card or phone, nothing in advance. As the van is on the way, dig out your policy: plenty cover misfuelling.
