Penprysg: AdBlue in the Diesel Tank? Find Your Situation
What to do about AdBlue in a diesel tank comes down to one thing more than any other: if the motor has been run since it went in. Anywhere your vehicle stands — Llanilid, Penprysg — never run a motor that hasn't been started yet. Keep nothing on, phone 0333 366 0103, and count on a thorough flush plus a drain, done right where the vehicle stands in Penprysg. When the motor has been run, stop safely first, then switch the vehicle off. Step one remains the same, even if the work is bigger.
Compare your case to one of the list below, anywhere around Bridgend you are.
Penprysg forecourt: AdBlue in a diesel at the pump
The cap you unscrewed was the wrong one — and you only spot it while you are stood at the pump, bottle or nozzle in hand. Be it Texaco, another forecourt nearby or anywhere else around Penprysg, the case is identical.
Meaning? Finding out on the forecourt is the best it gets. Still inside that tank, with nothing pulled onwards: that's where the AdBlue is.
Next: avoid the temptation to start it just to move away from the petrol pump. Ask the staff to help you roll the vehicle into a parking spot, keep the receipt or the bottle, then phone us from the forecourt. Stuck by the petrol pump? Explosion-proof equipment keeps a busy forecourt sensible, so it can be drained in place.
Penprysg, at home: AdBlue in the diesel tank
Days had gone by with the warning light on. Bought a container, tipped it in at home, binned the empty — and at that point checked the cap again, after the fact. Just off Islawen Meadows is no less likely from any other place.
Put simply: if your vehicle has not been driven since, it is almost as good as spotting it at the pump. AdBlue does not mix with diesel; it sinks to the bottom of that tank and waits there. Overnight does not change that.
Keep the keys in the house tonight — or someone might take it away at breakfast — and call us. Your drive is where it is drained, be it around Penprysg or Pencoed. Even at night, the pumps are quiet enough for a residential street.
AdBlue in a diesel and already driving around Penprysg?
Rough running, smoke, lost power or a glowing dashboard started a mile or two after the top-up. Perhaps it was on Pentwyn Road, possibly on the way out towards Cardiff, under 15 miles away.
The upshot: the system has pulled AdBlue through by now. Mileage sets how deep it gets: filter and pipework first, then the injection pump and every injector. It travels further with each extra mile driven and every restart.
Do this: stop somewhere safe, then turn your engine off. Leave at the first junction — not the services beyond — if you're on the M4, under a mile from Penprysg. Restarting it to test gets nothing — AdBlue never clears on its own. Call, and say what distance your vehicle was driven.
A hire or company car with AdBlue in the wrong tank?
A week ago, it was new to you. The AdBlue filler sits right beside the diesel one, which you did not know, because your own vehicle either has no AdBlue or keeps it somewhere else. It can happen to anyone, anywhere across Bridgend.
What it means: the same as the situations above, depending on whether it has run, with one more stage. Plenty of rental and company agreements require the owner's sign-off for work.
Next: phone the hire company or your fleet manager first, and then us — settling it before we arrive is faster. Stuck by St Davids Church or outside Pencoed until someone replies, the vehicle remains switched off the whole time.
Not sure it was AdBlue in your diesel tank, Penprysg?
"I think so" is often as honest as it gets. The bottle is lighter than it should be, there's a faint smell of ammonia around your filler, and you can't remember which cap you took off. A hurried top-up by the gates of the local primary school, or a call to a friend in Wern Tarw: either fit.
What it means: a little spilled round the filler does no damage to your motor. A diesel tank with AdBlue in it is a different matter. You cannot tell which by turning the ignition, and doing so will draw in any AdBlue that is in your tank.
Next: assume it went in, then keep the motor off. Phone with the details: we'd sooner confirm a clean tank than empty one once your engine has run.
The common ground in every Penprysg AdBlue drain
Every case has the same start to the work. Three things are asked when our engineers reach the car — at a forecourt, a drive, a street beside Pencoed Church Hall or the car park at The Chatterton Arms: the fluid, the amount, and if it has run. Those answers determine this work, and you get our quote by phone, before anyone heads out.
AdBlue forms crystals and eats at some metals used in fuel systems, and so it does not rinse out on its own; that is why the flush, after this drain, matters far more with AdBlue than with petrol. Clean diesel goes in once your filter is cleaned or changed, and your car is finally checked. Where your engine has not run, expect roughly half an hour on site, in most cases.
The final step is firing it up. With new diesel in, it runs while we check it's running smoothly, and then we go. The entire job is done where the car is, and when it is noticed early, permanent 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: lots of insurers offer misfuelling cover, so a quick look at your documents as we travel is worthwhile.
