Everything hinges on a single detail: if your motor has started after the AdBlue was added — more than anything else. Wherever your car stands — Moorlinch, Catcott — don't start a motor that has not run yet. Normally this means draining and thoroughly cleaning it right there around Catcott — so keep the ignition and motor off and ring 0333 366 0103. Stop the minute it is safe and switch off, if it has already run. The job is bigger, but the first stage is the same. Anywhere across Somerset it happened, one of the situations below fits yours. ## Catcott forecourt: AdBlue in a diesel at the pump Just now, bottle yet in your hand, it dawns on you that the cap you took off was the wrong one, right at the petrol pump. It could be the Murco, or perhaps the Shell, or another station in Catcott. Put simply: no better spot exists to spot it. Still in that tank, and nothing pulled onwards: that is where the AdBlue sits. Do this: stay out of the car, even if the queue wants clearing. Ask the attendants to help you roll the car into a parking spot, keep the receipt or the bottle, and ring us from the forecourt. The equipment is explosion-proof and safe on a live forecourt, and so a vehicle that can't be pushed clear gets cleared where it is at the petrol pump. ## Catcott, at home: AdBlue in your diesel tank For days the dashboard had been warning you. Only at the recycling bin, the empty container in your hand, did you look back at the cap you'd opened on the driveway. Drives close to Church Way get it as much as anywhere. Meaning? As long as your car hasn't moved since, it's second to the pump case. On the bottom of the tank sits exactly where AdBlue waits, because it won't mix with diesel — and a night passing makes no difference. Your move: keys in the house, so nobody takes the vehicle anywhere first thing. After that, ring. Your driveway is where it gets drained, whether around Catcott or Edington. The pumps are quiet enough to use outside a house after dark. ## Catcott: set off with AdBlue in a diesel? A mile or two after topping up, your motor began playing up: rough running, smoke, lost power, lights on the dash. King William Road, say, or the way to Wells — a run of under 15 miles. In short: the AdBlue has been pulled through your fuel system. Distance decides how far it gets: filter and lines to begin with, then the high-pressure pump and each injector. More miles, more restarts: deeper it goes. Stop safely — that's the first job — then switch it off. On the M5, under 5 miles from Catcott, that means the next exit, not the services further on. It will not have cleared, and so there is no point restarting to find out. Roughly what distance did it go? Say so when you phone. ## Hire, lease or company car with AdBlue in the wrong tank It is a car you have had for a week. Your own vehicle either does without AdBlue or keeps it somewhere different, and so nothing told you the AdBlue inlet sits just next to the diesel. Wherever you happen to be around Somerset, any driver could be caught. The point: just as above, split by if it ran, only with one added step. Plenty of hire and fleet contracts require the owner's sign-off before repairs. Sorting it before the van turn up is faster, and so phone the rental company or your fleet manager, then us. If you're stranded in the car park outside Bridgwater, or by St Peter, whilst you wait for an answer, leave your car off. ## Not sure it was AdBlue in your diesel tank, Catcott? "I think so" is sometimes as honest as it gets. Lighter, the bottle; a hint of ammonia round your filler; no clear memory of which cap. Look familiar? Maybe at a friend's driveway in Stawell, or in a rush outside Catcott Primary School on the school run. The upshot: your engine is not hurt by some AdBlue splashed around the filler. If it is inside the diesel tank, though, that changes. Any AdBlue in the tank would be sucked in by starting the car, and the start wouldn't settle which it is in any case. Next: act as though it went in, then leave the engine off. Phone with what you saw: we would rather confirm a clean tank than drain one after the engine has been run. ## The common ground in every Catcott AdBlue drain The job opens the same way, whatever the situation. Three questions are asked when our technicians arrive — at a filling station, a driveway, a road by Catcott War Memorial or the car park outside The Crown Inn: the liquid, the amount, and if it has run. On the phone, before anything else, you are told our price, and those answers decide the job too. Draining that tank comes next, then a full flush — more important after urea than with petrol, since crystals and corrosion will not go on their own, no matter how long you wait. Next is the filter — cleaned, or swapped when needed — followed by fresh diesel, and a test of your car. Most unstarted vehicles are a half-hour job from the moment our technicians turn up. Starting the engine comes last. Before our engineers head off, it's checked to make sure it runs properly on new diesel. When it is noticed soon, the car very rarely has lasting damage, and the whole job takes place where it is. Paying is that day, never in advance. For your insurer, there is a VAT invoice plus a written report from the engineer. Many insurance policies include misfuelling cover, so it is worth checking yours whilst we are on the way. ## About Catcott, for a moment Catcott is a small village in inland Somerset, situated near the villages of Edington, Chilton Polden, and Shapwick.
