Then put this page aside for now, leave your ignition and engine off, and call 0333 366 0103. In Farm Cross, finding it before the engine turns normally leaves a drain and a full flush on the spot. If you're reading before it has happened, the rest of this page is about why it occurs and how to make sure it does not. ## AdBlue in a diesel car, and its separate tank Diesel goes to your engine — yet many modern diesels seen about Farm Cross and Shawfield hold another fluid too. Your exhaust, not the engine, is where AdBlue ends up: dosed into the fumes to fresh them, from its own tank. Each tank has one filler of its own. On a lot of motors the two sit side by side under the same flap; on others the AdBlue filler is in the boot or under the bonnet. The diesel side is filled at the pump all the time. Much less regularly, the AdBlue side gets topped up — normally from a bottle, by a person thinking about where it goes. The mistake lives in that gap. ## AdBlue in the diesel tank around Farm Cross: how it takes place Three things tend to line up, and carelessness is seldom one of them. On a drive off Downiebrae Road before work, or in the car park at Wee Mill heading home: that's where the rushed top-up happens. Why the rush? As AdBlue runs low the car warns you, and once it is gone, limp mode follows. New-to-you cars come next, too. Rentals, new motors and company vehicles put their fillers in new places, and the hand reaches for the cap used on the old one. And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, and so nothing stops the pour after it has started. Whether it takes place in Dalmarnock or the middle of Farm Cross, it's the same few seconds. ## The AdBlue filler and your diesel filler: telling them apart A couple of seconds is all the checks take — so run through them before you tip anything, on a driveway in Oatlands or a forecourt in Farm Cross. - Check the cap instead of going by position: AdBlue ones are regularly blue or marked "AdBlue", and diesel caps normally aren't. - Look at the size: the smaller filler neck is, on plenty of vehicles, the AdBlue one. - The flap. Look inside the fuel flap for a label. Plenty of vehicles say there which fuel goes where. - The handbook. If the filler is not by the diesel cap, it's in the boot or under the bonnet, and the handbook says which. - Collecting a hire or company car, perhaps at the car park at Dalmarnock? Ask the person who drove it last before you set off, not once the light comes on. ## AdBlue top-ups that never reach your diesel tank Wherever in South Lanarkshire the light comes on, this is a routine for that day. - Park then switch off. Not on a slope, not with your motor running, and not in a rush on the side of Dalmarnock Bridge. - Say "AdBlue" out loud as you unscrew the cap, once finding the AdBlue filler and read it. Daft, perhaps, yet it works. - The diesel cap remains on. Where both share a flap, confirm it is closed before lifting the bottle. - Tip slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty. - Only after that, start the car: close the cap, check once more, and make sure your diesel cap was never opened. Stop there if you find, at stage two or three, that you've already poured into your diesel side. Leave out step five altogether. ## Put AdBlue in your diesel tank around Farm Cross already? What follows is a short order of things, beginning with not starting your engine. Keep your ignition off too, because on many diesels it alone starts the pump. Do not top up with diesel to thin it: AdBlue doesn't mix with diesel, it sinks to the bottom of the tank, where your fuel is sucked from. At a forecourt — Tesco, BP or another — the attendants will normally help roll your car clear, if you ask. On your own drive in Farm Cross? So your car remains put. When the engine has been run already, pull over safely then turn the vehicle off. Leave the M74 — under a mile out of Farm Cross — at the first junction. Tell us roughly how far it went: a run towards Glasgow, under 3 miles away, is a bigger job than a short hop across Farm Cross. ## What occurs when our technicians arrive around Farm Cross Anywhere the vehicle came to rest, whether by the local primary school, beside Slipstream or at home, our van comes to it. Those replies decide this work and our price, and so we ask what got in, roughly how much, and if it has run. No one heads out before you've had the quote over the phone. Emptying the tank comes next, then a full flush of your system. AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it doesn't wash out on its own — which is why that matters more here than with petrol. The filter is flushed, or replaced where it needs to be; fresh diesel goes in; and the car is tested. After that we start it and check it runs smoothly before we go. Unstarted cars mostly need a half-hour visit from arrival. The kit is fine on a busy filling station, and quiet enough for a residential street after dark. Paying happens on the day, not upfront, and you receive the paperwork an insurer asks for: an engineer report and a VAT invoice. While we travel, have a look at your policy; plenty carry cover for misfuelling. ## About Farm Cross Farm Cross is a suburban area located on the riverside in South Lanarkshire, with a low elevation of around 5 metres.
