Coed Mawr: AdBlue in the Diesel Tank? Find Your Situation
All of that hinges on one fact: whether your motor has started since the AdBlue went in — more than anything else. Not started so far? Then leave the car that way, whether the vehicle is — Coed Mawr or Minffordd. Phone 0333 366 0103 with the key and engine still off. Across Coed Mawr, such a case is generally drained and cleaned where it stands. Where your engine has run, pull in somewhere safe first, then turn it off. Step one remains the same, even if the work is bigger.
Match your case to a situation from the ones below, wherever across Gwynedd you happen to be.
AdBlue in a diesel on a Coed Mawr forecourt
Picture it: standing by the pump, holding the nozzle, you realise the filler you opened wasn't the correct one. Possibly you're at the Texaco, perhaps at the Tesco, maybe somewhere else in Coed Mawr.
Meaning? Finding out on the forecourt is the best it gets. Nothing has pulled it in, and so the AdBlue sits only in that tank.
Next: resist the temptation to start it just to move away from the pump. A few things: a push into a bay with the staff helping, the bottle saved, and a ring to us from where you stand. Stuck by the pump? Explosion-proof kit keeps a live forecourt sensible, so it can be drained in place.
Coed Mawr, at home: AdBlue in your diesel tank
For days the dashboard had been warning you. A bottle bought at the shop, tipped in at the drive — and it's only by the bin that the cap caught your eye. Houses just off Ffordd Coed Mawr get caught out as much as everywhere else.
What it means: if you haven't driven since, this is almost as good as the forecourt. Diesel and AdBlue stay apart: the AdBlue drops to the base of that tank and stays there, however long it waits.
Next: stop an early-morning move by keeping your keys in the house, then phone us. In Bryn-Llwyd or right here around Coed Mawr, the drain is done at your driveway. Late-night drains beside a house are fine: the pumps are low-noise.
On the road around Coed Mawr with AdBlue in a diesel
Rough running, smoke, falling power or a glowing dashboard started a mile or two after the fill. Cil Coed, say, or the route to Bangor — a trip of under 3 miles.
What it means: your fuel system has pulled the AdBlue in. Through the fuel filter, along the lines, and — the further the mileage — on into the high-pressure pump and each injector. It travels further with each extra mile driven and each restart.
Next: find a safe place, stop, then switch the engine off. Leave at the next junction — not the services further along — if you're on the Moreton Spur, under 50 miles from Coed Mawr. Do not restart the vehicle to see if it has cleared; it will not have. Tell us know the mileage covered when you call.
AdBlue in the wrong tank of a hire, lease or company car
You have just driven the vehicle for days. Unknown to you, the AdBlue and diesel fillers are next to each other here — not like your own car, which has no AdBlue or keeps it in another spot. Throughout Gwynedd, no one is immune.
In short: an extra step on top of the cases above, which turn on if it's run. Many rental and company contracts need the owner's approval before repairs.
Next: phone the hire company or your fleet manager first, then us — sorting it before we arrive is quicker. If you are stuck in the car park outside Bangor (Gwynedd), or by Coed Mawr Community Centre, whilst you wait for an answer, leave the car off.
Unsure about AdBlue in your diesel tank in Coed Mawr?
Sometimes the fair answer is "I think so". Which cap came off, you cannot say; but the bottle feels lighter than expected, and ammonia lingers by the filler. Maybe on a friend's driveway in Penrhos Garnedd, or in a rush outside the local primary school on the school run.
The point: the engine is not hurt by a little AdBlue splashed around the outside. Inside your diesel tank, however, AdBlue damages it. Any AdBlue in that tank will be sucked in by starting the car, and the start wouldn't settle which it is in any case.
Assume it got in, and don't start your engine. Describe what you saw on the phone. A clear tank checked counts as a better outcome than a run one emptied.
The common ground in each Coed Mawr AdBlue drain
Every case gets the same opening to the job. Our engineers come to the vehicle, whether it's on a forecourt, a drive, the car park outside The Union or a side street close to Capel Berea Newydd, and ask three things: what went in, roughly how much, and whether the motor has been run. Those replies settle this work, and you hear the price on the phone, before anyone sets off.
AdBlue forms crystals and is corrosive to some metals in fuel systems, and so it does not wash out unaided; that's why a full flush, after the drain, matters far more here than with petrol. Fresh diesel goes in once your filter has been flushed or replaced, and the car is then tested. Most unrun cars are a half-hour job after the moment our engineers get there.
Our technicians fire it up at the end. Before our engineers leave, it's checked to confirm it runs properly on new diesel. The whole job is done where the vehicle is, and when it is noticed early, lasting damage is very unusual. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Worth knowing: many insurers offer misfuelling cover, so a quick look at your policy as we travel is worthwhile.
