Usually, when the motor has not run, it's drained and fully rinsed where the vehicle is around East Kilbride. The remainder of this page covers why it happens and how to ensure it doesn't — useful if you're reading before it has happened. ## Why does AdBlue in a diesel car need its own filler? Diesel feeds your motor — yet many newer diesels seen round East Kilbride and West Mains hold a second liquid too. Kept in a tank of its own, AdBlue is sprayed into the exhaust stream to clean it. Different tanks, different fillers. Under one flap, side by side: that is the arrangement on many vehicles. Elsewhere, AdBlue's filler is beneath the bonnet or in your boot instead. The diesel side is filled at the petrol pump all the time. The AdBlue side is fuelled far less often, usually from a bottle, and normally by a person who has to stop and think where it goes. The mistake grows in the gap between them. ## AdBlue in your diesel tank in East Kilbride: how it takes place Three things tend to come together, and carelessness is seldom one of them. Hurry comes from the warning. The car tells you as AdBlue runs low, and an empty tank sends it into limp mode — so the top-up gets done quickly, before work on a drive off Birniehill Roundabout, or heading home in the car park outside Hudsons. Then, the hand goes for the cap it would have used on the old vehicle — because a hire car, a new car or a company car puts the fillers somewhere your last one did not. And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, so nothing stops the pour once it has started. The same few seconds settle it, in the middle of East Kilbride or out in Birniehill. ## How to tell the AdBlue filler from the diesel one Whether a East Kilbride forecourt or a drive out in East Mains, take a few seconds on these before anything is poured in. - Colour and lettering: an AdBlue cap is commonly blue, or says "AdBlue", where a diesel cap normally doesn't. Trust the cap, not its position. - The size. On many motors the AdBlue filler neck is the smaller of the two. - A label inside your fuel flap frequently shows which fuel goes where, on many motors. Check for it. - In the boot or under the bonnet: that's where the filler sits if it is not by your diesel cap, and the handbook tells you which. - The person who drove the vehicle last. On a hire or company car collected from somewhere like the car park at the nearest station, ask before you leave, not when the light comes on. ## Topping up AdBlue without it reaching the diesel tank On the day the warning appears — wherever you are in South Lanarkshire — a routine to follow. - Switch off once parked — flat ground, engine stopped, and never in a rush by Queensway at the roadside. - Say "AdBlue" out loud as you unscrew the cap, after you find the AdBlue filler and reading it. Silly, yes, yet it works. - Both under one flap? Then make sure the cap on the diesel filler is still shut ahead of raising the bottle. - Using the bottle's own spout, pour slowly — and stop when it is full or the bottle is empty. - Only then, start your car: close the cap, check again, and make sure the diesel cap was never opened. If at step two or three you find you have already poured into the diesel side, stop there. Leave out stage five entirely. ## Put AdBlue in the diesel tank around East Kilbride already? Then the order of things is short. Don't start the engine. Leave your ignition off as well, since on plenty of diesels it alone runs your fuel pump. AdBlue does not mix with diesel — it sinks to the bottom of that tank, where your fuel is drawn from — so don't top up with diesel to dilute it. At a forecourt — Co-op, BP or another — the attendants will normally help roll the vehicle clear, when you ask. Your own driveway around East Kilbride is where it stays. If your engine has already run, stop as soon as it is safe and switch off. East Kilbride sits under 10 miles from the M74; on it, use the next exit. Roughly how far did it go? Hopping across East Kilbride is smaller work than a run of under 10 miles to Glasgow, and so say. ## Our arrival in East Kilbride, and what occurs next Anywhere the vehicle has stopped, whether outside the local primary school, beside St Mark's or on your own drive, the van comes to it. Which liquid got in, the quantity, and whether it ran: our technicians ask since the replies set both work and price. On the call itself, you are told the quote — before anything else. Your system is then rinsed thoroughly, once the tank is emptied. With AdBlue that counts more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, and so it doesn't wash out on its own. The filter is flushed, or replaced where it needs to be; fresh diesel goes in; and your car is tested. Before we go, we fire it up and confirm that it is running correctly. Unstarted vehicles usually mean a half-hour visit after the moment we arrive. The kit is fine on a busy filling station, and hushed enough for a residential street after dark. No money upfront; you settle up on the day. Afterwards, a VAT invoice and a report from the engineer are handed to you for your insurer. Misfuelling cover is included in plenty of insurance policies — and so use the wait to check yours. ## About East Kilbride and where it is East Kilbride is a town in South Lanarkshire, situated on the banks of the River Clyde, with a mix of flat and other types of housing.
