AdBlue in the Diesel Tank in Cross Inn, and What to Do Next
Has the engine run since the AdBlue went in? This one question decides almost everything about what comes next. If it hasn't, keep it that way, whether the vehicle is in Cross Inn itself or out in Brynteg. Normally that means draining and thoroughly flushing it on the spot in Cross Inn — so leave the ignition and motor off and call 0333 366 0103. If it has run, stop as soon as it is safe and switch off. Step one remains the same, even though the job grows.
Below: the cases our engineers see, anywhere around Rhondda Cynon Taf. Choose the one that fits.
Cross Inn forecourt: AdBlue in a diesel at the pump
The cap you unscrewed was the wrong one — and you just notice it while you are stood at the petrol pump, bottle or nozzle in hand. Perhaps you are at the Tesco, possibly at the Sainsbury's, maybe somewhere else in Cross Inn.
Meaning? Finding out on the forecourt is as good as it can be. Just your tank has AdBlue; not one component past it has taken it in.
Your move: stay out of the driver's seat, even if the pump needs freeing. Get the staff to help rolling it into a space, save the bottle, then ring us from there. If it can't be moved, it can be drained at the pump: the equipment is explosion-proof and safe on a busy forecourt.
AdBlue in your diesel tank on a Cross Inn drive?
For days the dash had been warning you. Only by the recycling, the empty container in your hand, did you look back at the cap you had used on the drive. It occurs on driveways just off Cardiff Road as often as anywhere.
Meaning? Provided the vehicle has not been driven since, it's close to the pump case. AdBlue does not mix with diesel; it sinks to the bottom of that tank and waits there. Overnight does not change that.
Next: stop an early-morning move by putting the keys indoors, then phone us. In Llantrisant or right here in Cross Inn, the draining is done on your driveway. The equipment runs quietly enough that it won't wake the street at night.
Cross Inn: set off with AdBlue in a diesel?
A mile or two beyond filling up, the motor began playing up: roughness, smoke, less power, lights on the dash. Possibly it was on Main Road, maybe on the way out towards Cardiff, under 10 miles away.
What it means: the system has pulled the AdBlue in. The high-pressure pump and each injector get it too on a longer trip, after the filter and pipework have had it. More miles, more restarts: deeper it goes.
Pull in somewhere safe — that's the first job — then turn it off. Cross Inn sits under 3 miles from the M4; there, come off at the first junction instead of pushing on to the services. Starting it again to test achieves nothing — AdBlue doesn't clear itself. Phone us and say how far you drove.
AdBlue in the wrong tank: hire, lease and company motors
It's a motor you have had for a week. Your own motor either does without AdBlue or keeps it somewhere different, so nothing warned you the AdBlue cap sits right beside the diesel. Throughout Rhondda Cynon Taf, no one is safe from it.
Meaning? Whatever applies above counts here — run or not — and one extra stage. Plenty of hire and fleet agreements require the owner's sign-off before repairs.
What to do: call the hire firm or your fleet manager first, then us. That's quicker settled before our technicians turn up than after. Hanging on for an answer in the car park outside Pontyclun, or beside Llantrisant Leisure Centre? Leave your car off meanwhile.
AdBlue in the diesel tank? Not sure, around Cross Inn
Now and then, "I think so" is all anyone can honestly say. Which cap came off, you cannot recall; but the bottle feels lighter than expected, and a whiff of ammonia lingers by your filler. It might have been on a friend's drive in Talbot Green, or rushing outside the local primary school at the school run.
The point: the motor is not hurt by some AdBlue splashed around the filler. The diesel tank with AdBlue inside is a different matter. Any AdBlue in that tank would be sucked in by firing up your car, and the start wouldn't settle which it is in any case.
Take it that it went in, and never start your engine. Describe what you saw on your phone. A clear tank looked at counts as a happier outcome than an already-run one drained.
Every AdBlue drain in Cross Inn shares these stages
No matter the case, a single start applies. Our technicians come to the vehicle, whether it is on a forecourt, a driveway, the car park at the pub in the village or a side street near Llantrisant Library, and ask three things: what went in, about how much, and whether the engine has been run. On the phone, before dispatch, you are told the price, and those replies shape the work too.
AdBlue crystallises and is corrosive to some metals in fuel systems, so it does not rinse out on its own; that's why the flush, after this drain, matters far more with AdBlue than with petrol. Last are the fuel filter, cleaned or replaced if necessary; fresh diesel; and a test of your car. Most unstarted vehicles are a half-hour visit after the moment our engineers get there.
Starting it comes last. Our check that it runs properly on clean diesel comes before our engineers head off. The entire job is done where the vehicle is, and if it's spotted quickly, permanent damage is very unusual. Payment is that day, never upfront. For your insurer, there is a VAT invoice plus a written report from the engineer. It is worth knowing: many insurers include misfuelling cover, and so a check of your documents as we travel is worthwhile.
