Normally, when your engine has not run, it is drained and fully flushed where your vehicle sits around Jordanhill. Here in advance? Then the rest explains why it comes about and what to prevent it happening at all. ## AdBlue in a diesel vehicle, and its separate tank No single liquid but two: that's what plenty of modern diesels near Jordanhill and Scotstounhill carry, with diesel for your engine. AdBlue goes to the exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own. There is a filler on every tank. Under one flap, side by side: that's the layout on many vehicles. Elsewhere, AdBlue's filler sits beneath the bonnet or in your boot instead. At the pump, your diesel side is topped up all the time. Rarely filled, AdBlue normally goes in from a bottle, tipped by someone who has to stop and think which filler it needs. The error lives in that gap. ## How AdBlue in your diesel tank takes place around Jordanhill Rarely is it carelessness: normally three things line up. The warning comes first. As AdBlue runs low the vehicle tells you, and if it runs out completely, the vehicle goes into limp mode. So the top-up is done in a hurry: on a drive off Southbrae Gardens before work, or in the car park at The Three Craws on the way home. Then your car is new. A hire car, a new car or a company car puts the fillers where your last one didn't, and your hand gets to for the cap it would have used on the old one. A spouted bottle meets no obstacle at a diesel filler no more than at an AdBlue one. And so the tip, after begun, keeps on. It takes a few seconds, be it in Scotstoun or right in the centre of Jordanhill. ## How to tell the AdBlue filler from the diesel one A few seconds is all the checks take — so run through them before you pour anything, on a driveway in Broomhill or a forecourt in Jordanhill. - Check the cap instead of going by where it sits: AdBlue ones are frequently blue or marked "AdBlue", and diesel caps usually are not. - Look at the size: the smaller neck is, on many motors, the AdBlue one. - A label inside your fuel flap frequently says which fuel goes where, on many cars. Look for it. - The handbook. If your filler isn't by your diesel cap, it is in your boot or under the bonnet, and the handbook says which. - The previous driver knows. Ask as you collect a hire car or company car — at the nearest station's car park, say — not when the light appears. ## AdBlue top-ups that never reach your diesel tank Wherever around Glasgow City the light comes on, this is a routine for the day. - Switch off after you park — level ground, motor stopped, and not in a rush beside School Drive on the verge. - Say "AdBlue" out loud as you unscrew the cap, once you find the AdBlue filler and reading it. Daft, perhaps, yet it works. - The diesel cap remains on. Where the two sit under a flap, confirm it's closed before lifting the bottle. - Tip slowly, using the bottle's own spout. Stop when it is full or when the bottle is empty. - Close the cap and check again. Make sure your diesel cap was never opened. Only then start the car. Stop there if you find, at stage two or three, that you have already poured into the diesel side. Don't go on to step five. ## Jordanhill: already put AdBlue in your diesel tank? Brief list, then. First: the motor stays unstarted. Keep your ignition off as well, since on many diesels switching it on by itself starts your fuel pump. Topping up with diesel will not dilute it: rather than mixing, AdBlue sinks to the bottom of that tank, right where the fuel is taken from. Ask the staff to help roll the car clear of the pump if you are at a forecourt — the BP, the Esso or anywhere else. Leave it where it is if you're on your own drive in Jordanhill. Already run? Pull over once it is sensible, then turn off. On the M8, under 3 miles from Jordanhill, that means the next exit. Tell us roughly how far it went: a run towards Glasgow, under 5 miles away, is a bigger job than a short hop across Jordanhill. ## Jordanhill: what takes place when our technicians get there Anywhere the vehicle came to rest, whether by the local primary school, near Scotstoun Leisure Centre or at home, the van travels to it. Which fluid was put in, the quantity, and if it ran: our engineers ask since those answers decide the work and quote. You hear that quote by phone, before anybody sets off. Next: a drain, then a full flush of the whole system. Not like petrol, AdBlue leaves crystals and eats at some fuel-system metals, and neither washes away by itself. That is why it matters more. Once the filter has been flushed — or renewed, where required — clean diesel goes in, and then your vehicle is tested. We don't leave until it has been fired up and is running smoothly. Unstarted vehicles usually need a half-hour job after arrival. The equipment is fine on a busy forecourt, and hushed enough for a driveway late at night. Payment is on the day, not upfront, and you are given the paperwork an insurer asks for: an engineer report and a VAT invoice. Many insurance policies include misfuelling cover, and so it's worth checking yours whilst we're on the way. ## About Jordanhill itself Jordanhill is a suburban area in Glasgow City, situated approximately 4.2 miles west of Glasgow's city centre.
