Find Your Situation All of that turns on a single detail: if the motor has been run since the AdBlue was added — far more than anything else. Over in Dittisham or right around Dartmouth, an unstarted engine should remain unrun. Usually that means draining and thoroughly cleaning it right there around Dartmouth — and so keep your key and motor off then ring 0333 366 0103. When your engine has been run, pull in somewhere safe straight away, then switch the vehicle off. A bigger job, yes, but the identical first move. Find the situation below that matches yours, wherever across Devon it happened. ## On a Dartmouth forecourt with AdBlue in a diesel You're at the petrol pump, the nozzle or the bottle still in your hand, and you have just noticed the cap you opened was the wrong one. Whether Dart Fuel Barge, BP or somewhere else around Dartmouth, the situation is identical. In short: no better place exists to discover it. Still inside the tank, with no fuel pulled through: that is where the AdBlue is. Your move: stay out of the driver's seat, however much the queue needs clearing. A few jobs: a shove into a bay with the staff helping, the receipt kept, and a call to us from where you stand. The equipment is explosion-proof and fine on a live forecourt, so a vehicle that can't be pushed clear gets emptied right at the petrol pump. ## Dartmouth, at home: AdBlue in your diesel tank On the dash, a reminder had been lit for days. A bottle from the garage, tipped in on the drive — and it was just by the recycling that the cap caught a second look. Right off Market Street is not less likely from any other place. In short: if your vehicle has not been driven since, it's almost as good as finding out at the pump. As it is unable to blend, AdBlue drops to the base inside that tank and waits. A night parked changes none of that. Your move: the keys indoors, and so no one drives the car anywhere first thing. Then, ring. Your driveway is where it is emptied, whether around Dartmouth or Kingswear. The equipment works quiet enough that it won't wake the street at night. ## On the road around Dartmouth with AdBlue in a diesel You filled up, set off, and a mile or two later your engine began to run roughly, smoke, lose power or light up the dashboard. Perhaps it was on Lake Street, possibly on the way out towards Plymouth, under 25 miles away. In short: the AdBlue has been pulled through the system. Through the filter, along the pipework, and — the more the distance — on into the injection pump and every injector. Each restart, like each mile, carries it on. What to do: pull over where it's safe and switch off. Service stations further along are too far: on the M5, under 25 miles out of Dartmouth, take the first junction. No test starts: clearing itself isn't something AdBlue does. Phone, saying how far your vehicle went. ## AdBlue in the wrong tank of a hire, lease or company car It is a car you have had for a week. The AdBlue filler is right next to the diesel one, which you did not know, since your own motor either has no AdBlue or keeps it somewhere else. Anyone, anywhere around Devon, might do the same. What it means: the same as the situations above, depending on whether it's run, with one more step. Any work on your car frequently needs the owner's go-ahead under hire or fleet agreements. What to do: ring the hire firm or your fleet manager first, then us. That is quicker settled before our technicians arrive than after. Leave the car off while the answer arrives, even if you are parked at Paignton or close to Originals by Deni. ## Dartmouth: unsure if it was AdBlue in your diesel tank? "I think so" is sometimes as honest answer there is. Which cap came off, you can't say; but the bottle weighs less than it ought to, and ammonia hangs by the filler. The gates of St John the Baptist Roman Catholic Primary School, Dartmouth in a rush, perhaps, or a friend's drive over in Hillhead. What it means: a little spilled around your filler does no harm to your engine. If it is inside your diesel tank, though, it does. Turning on your car will not tell you which, and if there is AdBlue in your tank it would draw it in. What to do: treat it as if it got in. Don't crank it. Phone and give the details: we'd rather find a tank free of AdBlue than drain one after your motor has run. ## What every AdBlue drain in Dartmouth has in common Whichever situation you are in, this job starts the same way. Filling station, drive, Market House Inn's car park or a street by The Flavel — our van comes to your car, and three questions follow: what liquid, which quantity, and whether it has run. Answers set the work; the price comes by phone whilst nobody has left yet. Then that tank is emptied and the fuel system flushed thoroughly, which matters more with AdBlue than with petrol: AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it doesn't rinse out on its own. Fresh diesel is put in after the filter has been flushed or changed, and the car is finally checked. The majority of unrun cars are a half-hour visit after the moment our technicians get there. Our technicians start the car at the end. Before we leave, it is tested to confirm it runs smoothly on fresh diesel. Lasting damage is very rare when it is noticed soon, and the whole job is done where your car is. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Check your insurance while we arrive: misfuelling cover comes included in many policies. ## About Dartmouth, briefly Dartmouth is a coastal town in Devon, situated on the western bank of the River Dart estuary.
