Gulval: AdBlue in the Diesel Tank? Find Your Situation
One fact matters most once AdBlue is in a diesel tank, and it is if your engine has been started afterwards. Over in Treneere or right around Gulval, an unstarted motor should remain unrun. Switch nothing on, ring 0333 366 0103, and expect a proper flush plus a drain, done just where the vehicle sits around Gulval. Already started? Pull over once safe, then turn everything off. The job is bigger, yet the first step is the same.
Anywhere across Cornwall it took place, one of the cases below matches yours.
At the petrol pump around Gulval: AdBlue in a diesel
The cap you opened was the wrong one — and you only spot it as you are stood at the petrol pump, bottle or the nozzle in your hand. It could be the Sainsbury's, or perhaps the Tesco, or a different station in Gulval.
Put simply: no better spot exists to spot it. Nothing has pulled it in, so the AdBlue sits just inside your tank.
Your move: stay out of the driver's seat, however much the pump needs clearing. Have the staff to help rolling it into a space, hold on to the bottle, then phone us from there. The equipment is explosion-proof and fine on a busy forecourt, so a car that can't be pushed clear gets cleared right at the pump.
At home around Gulval with AdBlue in your diesel tank
The warning light had been on for days. Picked up a bottle, tipped it in at home, binned the empty — and only then checked the cap again, after the fact. It occurs on drives just off School Lane as frequently as anywhere.
The upshot: no driving since makes it almost equal to spotting it at the pump. AdBlue does not mix with diesel; it sinks to the bottom of the tank and waits there. Overnight does not change that.
Put your keys indoors tonight — otherwise someone may drive it off at breakfast — and call us. Trevarrack or Gulval: wherever your driveway is, that's where it is cleared. Night-time empties outside a house are fine: the pumps are low-noise.
On the road around Gulval with AdBlue in a diesel
Lumpy running, smoke, lost power or a glowing dashboard started a short way beyond the top-up. Posses Lane, perhaps, or the route to Truro — a trip of under 25 miles.
The upshot: your system has pulled AdBlue through by now. The injection pump and every injector see it too on a longer trip, after your filter and pipework have had it. More miles, more starts: deeper it goes.
Next: pick a sensible spot, stop, and switch your engine off. Leave by the first junction — not the services beyond — if you're on the M5, over 50 miles from Gulval. No test restarts: clearing itself isn't something AdBlue will do. Phone, and say what distance your car was driven.
Hire, lease or company car with AdBlue in the wrong tank
It is a motor you have had for a week. Unbeknown to you, the AdBlue and diesel fillers are side by side here — unlike your own vehicle, which has no AdBlue or stores it in another spot. Any driver, wherever around Cornwall, might make the same.
What it means: the same as the situations above, depending on whether it has run, with one more stage. Work on your vehicle often needs the owner's approval under hire or fleet agreements.
Settling it before the van arrives is faster, and so ring the hire company or your fleet manager, and then us. Waiting for an answer at the car park outside Penzance, or near St Gulval? Leave your car off throughout.
Not sure it was AdBlue in your diesel tank, Gulval?
At times, "I think so" is all you can honestly say. What cap came off, you cannot say; meanwhile the bottle weighs lighter than it ought to, and a whiff of ammonia hangs by your filler. Perhaps it happened in a hurry at the school gates at Gulval School, or on a friend's drive in Longrock.
What it means: a little spilled around your filler does no damage to your motor. AdBlue inside the diesel tank does. You can't tell which by turning the ignition, and doing so will suck in any AdBlue that is in the tank.
Your move: behave as though it did, and don't start the engine. Inspecting a tank that proves clean beats emptying one once it's been run — so phone then tell us what you saw.
What each AdBlue drain around Gulval has in common
The job opens identically, whichever your case. Filling station, driveway, The Coldstreamer's car park or a street beside Gulval Village Hall — our van comes to the car, and three answers follow: which liquid, what quantity, and whether it has run. Those answers settle this work, and you get the quote on the phone, before anybody heads out.
AdBlue forms crystals and eats at some metals used in fuel systems, and so it won't rinse out on its own; that is why a full flush, after the drain, counts far more with AdBlue than with petrol. The fuel filter is cleaned, or replaced where it needs to be; clean diesel goes in; and your car is tested. Where your engine hasn't run, expect about half an hour on site, in most cases.
Our engineers start the engine last. Our test that it runs correctly on new diesel comes before we head off. The entire job is done where your car is, and when it's spotted quickly, lasting damage is very uncommon. Nothing is paid upfront, payment happens on the day, and you receive what your insurer asks for: an engineer report and a VAT invoice. Plenty of insurance policies include misfuelling cover, so it is worth checking yours whilst we're on the way.
