A drain and a thorough flush, done right where the car stands around Newton-with-Scales, is usually what it takes when found before the motor runs. If you're reading before it has happened, the remainder of this page is about why it happens and how to make sure it does not. ## Two fillers, two tanks: AdBlue in a diesel motor Diesel goes to the engine — yet plenty of current diesels driven around Newton-with-Scales and Salwick carry another liquid as well. Your exhaust, not your engine, is where AdBlue goes: sprayed into the fumes to clean them, from a separate tank. Separate tanks, different fillers. Plenty of vehicles share a single flap for both, whereas some move the AdBlue filler to your boot or under the bonnet. Filling your diesel side at the pump goes on all the time. The AdBlue side is topped up far less regularly, normally from a bottle, and normally by a person who has to stop and think where it goes. It's in the gap that the error lives. ## AdBlue in your diesel tank in Newton-with-Scales: how it occurs Carelessness seldom explains it. Instead is three things lining up together. Haste comes from the warning. The vehicle tells you as AdBlue runs low, and an empty tank sends the vehicle into limp mode — so the top-up happens in a rush, before work on a drive off Bryning Lane, or on the way home in the car park at Bell & Bottle. Then, your hand reaches for the cap it knew on the old motor — because a rental car, a new motor or a company car places the fillers somewhere your last one didn't. No part halts the pour once it has started, because a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. It takes seconds, be it in Newton or right in the heart of Newton-with-Scales. ## How to tell the AdBlue filler from the diesel one Look at these first, on a forecourt around Newton-with-Scales or a driveway over in Treales. A few seconds, that's all. - Colour and lettering: an AdBlue cap is often blue, or says "AdBlue", where a diesel cap usually doesn't. Trust the cap, not where it sits. - Check the size: the smaller neck is, on many motors, the AdBlue one. - The flap. Look inside the fuel flap for a label. Plenty of cars say there which fuel goes where. - The handbook says which it lives if the filler is not next to the diesel cap: your boot, or under the bonnet. - The previous driver will know. Check as you pick up a rental or company car — from Salwick's car park, perhaps — not when the light appears. ## AdBlue top-ups that never reach the diesel tank A routine for the day the light comes on, wherever in Lancashire that is. - Not in a rush on the side of School Lane, not on a slope, not with the motor running: park then switch off first. - Say "AdBlue" out loud as you unscrew the cap, once finding the AdBlue filler and reading it. Daft, yes, yet it does the trick. - If both sit under one flap, check your diesel cap is still closed before you lift the bottle — and leave the car on. - Stop once your tank fills or the bottle runs dry; before that, tip slowly through its built-in spout. - Close the cap, and check again — making sure the diesel cap remained closed the whole time. Only then, start the car. Stop there if you find, at step two or three, that you have already poured into the diesel side. Skip stage five entirely. ## Newton-with-Scales: already put AdBlue in your diesel tank? Then the order of things is short. Do not start the motor. Keep your ignition off too, since on plenty of diesels it alone starts the fuel pump. AdBlue does not mix with diesel — it sinks to the bottom of your tank, where your fuel is pulled from — so do not top up with diesel to dilute it. If you are on a forecourt, whether it's the Texaco or the another forecourt nearby, ask the staff to help roll the vehicle clear of the pump. On your own drive in Newton-with-Scales? So the vehicle remains put. Stop as soon as it is safe then switch off, if the engine has already run. Newton-with-Scales sits under 3 miles from the M55; on it, use the next exit. A short hop across Newton-with-Scales is a smaller job than a run towards Preston, under 10 miles away, and so tell us about how far it went. ## When our engineers turn up around Newton-with-Scales, what occurs? Anywhere your car came to rest, be it outside Newton Bluecoat Church of England Primary School, beside St John the Evangelist or at home, our van travels to it. The answers decide the work and our quote, and so our engineers ask what was put in, roughly how much, and if it has run. During the phone call itself, you hear the quote — before anything else. The system is then purged thoroughly, once your tank is emptied. AdBlue crystallises and is corrosive to some of the metals in a fuel system, and so it doesn't wash out on its own — which is why the flush counts more with AdBlue than with petrol. The filter flushed or, if needed, replaced; fresh diesel in; and then a test of the car. We don't go until it has been fired up and is running correctly. If your motor has not run, the majority of jobs take about half an hour once we are there, using pumps that are fine on a working forecourt and quiet enough to use outside a house at night. Your insurer will ask for the engineer's report and the VAT invoice, and both are yours once this job is done. Payment is on the day, with no money upfront. It is worth checking your policy as the van travels to you: misfuelling cover comes with plenty of policies. ## About Newton-with-Scales and where it is Newton-with-Scales is a village in Lancashire, situated inland at an elevation of 18 metres, approximately 5.8 miles from Preston.
