What Now? AdBlue in the Diesel Tank in Underwood
One fact matters most once AdBlue is in a diesel tank, and it is whether your motor has run since. Wherever the car stands — Cats Ash, Underwood — never start an engine that hasn't been started yet. Switch nothing on, phone 0333 366 0103, then count on a proper flush after a drain, done right where the car stands around Underwood. Already run? Pull over once safe, then switch everything off. It's a bigger job, though step one does not change.
Further down: the cases our engineers see, wherever across Newport. Pick the one that fits.
Underwood forecourt: AdBlue in a diesel at the pump
You are at the pump, the nozzle or the bottle still in your hand, and you have just noticed the cap you opened was the wrong one. Maybe you're at the Esso, possibly at the BP, perhaps somewhere else around Underwood.
In short: there is no better spot exists to spot it. Only the tank holds AdBlue; no part past it has taken any in.
What to do: don't get back in and crank it to clear the petrol pump. Phone us from the forecourt once your car sits in a space — the attendants will lend a hand to push it — then keep the receipt. Stuck by the petrol pump? Our explosion-proof equipment makes a busy forecourt safe, so we can drain it where it is.
AdBlue in the diesel tank on a Underwood drive?
The warning light had been on for days. A bottle bought at the shop, tipped in at the driveway — and it's only by the recycling that the cap caught your eye. Drives near Hazel Road see it as much as anywhere.
What it means: if you haven't driven since, this is nearly as good as the forecourt. AdBlue does not mix with diesel; it sinks to the bottom of that tank and waits there. Overnight doesn't change that.
Keep your keys indoors overnight — or someone may drive it off first thing — then phone us. Out in Llanmartin or here around Underwood, the drain happens at your drive. Late-night clears outside a house are no problem: the pumps are quiet.
On the road around Underwood with AdBlue in a diesel
A short way beyond filling up, the motor began misbehaving: roughness, smoke, less power, warnings on the dash. It might have been driving to Newport, under 5 miles away, or simply down Birch Grove.
What it means: the fuel system has drawn the AdBlue in. It's been through your filter and the fuel lines and, the further you went, into your high-pressure pump and the injectors. It travels further with every mile covered and each restart.
What to do: pull over where it's safe to do so then switch off. Leave at the first junction — not the services beyond — if you are on the M4, under a mile from Underwood. Restarting it to test gets nothing — AdBlue doesn't clear itself. Phone us and say how far you travelled.
Hire, lease or company car with AdBlue in the wrong tank
You have only driven this vehicle a week. Your own car either has no AdBlue or puts it elsewhere, and so no one told you the AdBlue inlet sits just next to your diesel. It can happen to anyone, anywhere across Newport.
The upshot: exactly as above, divided by whether it ran, only with an added step. Many rental and fleet agreements need the owner's approval before repairs.
What to do: ring the hire firm or your fleet manager first, then us. That's faster settled before we arrive than after. Hanging on for a reply in the car park at Newport (South Wales), or beside Langstone Village Hall? Keep the car off throughout.
Underwood: unsure whether it was AdBlue in your diesel tank?
Honestly, the best answer may be that you think it did. Too light, that bottle; a trace of ammonia round the filler; no clear recollection of which cap. Sound familiar? Perhaps it happened in a hurry at the school gates at the local primary school, or on a friend's drive in Llanwern.
Put simply: spillage near the filler does your motor no harm. Inside your diesel tank, by contrast, AdBlue harms it. If there is AdBlue in your tank, turning on the car will draw it in, and it would not tell you which either.
What to do: treat it as if it got in. Do not fire it up. Call us and describe what you saw; we'd rather check a tank that turns out free of AdBlue than drain one that has already been run.
The common ground in each Underwood AdBlue drain
No matter the case, one start applies. Three things are asked when we reach the car — at a filling station, a drive, a street beside St Cadwaladr's Church or the car park outside The Old Barn: the fluid, the amount, and whether it has run. The price is given on the call, before a van leaves, and the replies set the work.
AdBlue forms crystals and is corrosive to some metals used in fuel systems, so it won't wash out on its own; that is why the flush, after this drain, matters much more here than with petrol. The fuel filter is cleaned, or replaced where it needs to be; clean diesel goes in; and the vehicle is tested. Where the motor has not run, allow roughly half an hour once we arrive, for most cases.
Our engineers fire it up at the end. Before our technicians go, it's tested to make sure it runs properly on fresh diesel. We do the entire job where your car is, and long-term damage is very uncommon if it has been caught early. Payment is that day, never upfront. For your insurer, there is a VAT invoice plus a report from the engineer. Plenty of insurance policies include misfuelling cover, and so it's worth checking yours whilst we're on the way.
