In that case put this page down for now, keep your ignition and motor off, then ring 0333 366 0103. In Hamilton, catching it before the engine runs normally leaves draining and a full flush on the spot. Here in advance? In that case what follows covers why it happens and what to stop it happening at all. ## AdBlue in a diesel vehicle: two tanks, two fillers No single liquid but two: that is what plenty of newer diesels around Hamilton and Chantinghall run, with diesel for the engine. Its own tank keeps it, and from there it goes to your exhaust, where a spray cleans the fumes. Every tank has a filler of its own. Some cars put the AdBlue filler in your boot or under the bonnet; plenty of others place both side by side behind one flap. At the pump, the diesel side is topped up all the time. A driver who has to stop and work out where it goes normally tops up the AdBlue side, from a bottle, and much less commonly. It's in that gap that the error lives. ## How does AdBlue in your diesel tank occur around Hamilton? Three things tend to come together, and carelessness is rarely one of them. Haste comes from the warning. The car warns you as AdBlue runs low, and a dry tank puts the vehicle into limp mode — so the top-up happens in a rush, before work on a driveway off Cadzow Street, or heading home in the car park at Hemingways. Unfamiliar motors come second, too. Rentals, new vehicles and company vehicles place their fillers differently, and the hand goes for the cap used on the old one. Nothing 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. Whether it takes place in Silvertonhill or the middle of Hamilton, it's the same few seconds. ## The AdBlue filler and the diesel filler: telling them apart Look at these first, at a forecourt around Hamilton or a driveway out in Ferniegair. A few seconds, that's all. - Blue and lettering: an AdBlue cap is often blue, or says "AdBlue", where a diesel cap usually doesn't. Trust the cap, not its position. - The size. On plenty of motors the AdBlue filler neck is the smaller of the two. - The flap. Look inside the fuel flap for a label. Many cars say there which fuel goes where. - The handbook says which it is when your filler is not next to your diesel cap: your boot, or under the bonnet. - Collecting a hire or company car, perhaps at the car park at Hamilton Central? Ask whoever drove the vehicle last before you set off, rather than once the light goes on. ## Keeping AdBlue out of your diesel tank when you top up For the day the light appears — wherever you are around South Lanarkshire — a routine to use. - Not in a rush on the side of Quarry Street, not on a slope, not with your motor running: park and switch off properly. - Say "AdBlue" out loud as you unscrew the cap, once you find the AdBlue filler and read it. Silly, perhaps, but it does the trick. - The diesel cap remains on. Where both sit under a flap, confirm it is shut before the bottle comes up. - Finish once the tank fills or the bottle runs dry; before that, pour gently through its built-in spout. - Close the cap, then look again — confirm your diesel cap remained shut throughout. Only then, start your car. Find at step two or three that it has already gone into your diesel side? So stop just there. Don't go on to step five. ## Already put AdBlue in the diesel tank around Hamilton? Then the order of things is short. Don't start the engine. Do not switch your ignition on; on many diesels that alone runs the fuel pump. Topping up with diesel will not thin it: instead, AdBlue sinks to the base of your tank, right where the fuel is drawn from. On a forecourt — Esso, Shell or another — the staff will normally help roll the vehicle away, when you ask. If you're on your own driveway in Hamilton, leave the car where it stands. Already started? Stop when it is sensible, then turn off. Leave the M74 — under a mile out of Hamilton — at the first junction. Tell us about how far it went: a run towards Glasgow, under 15 miles away, is a bigger job than a short hop across Hamilton. ## What happens when our engineers turn up around Hamilton We come to the car wherever it has stopped, whether that is outside the local primary school, near District Court or on your own driveway. Which fluid was put in, the quantity, and whether it ran: our technicians ask since the answers decide the work and quote. You hear that price on the phone, before anybody sets off. Then that tank is drained and the system cleaned thoroughly. With AdBlue that counts more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, so it doesn't wash out on its own. A test comes last: before that, clean diesel is added, and the fuel filter is cleaned or replaced if necessary. We don't leave until it has been started and is running correctly. If the motor has not run, the majority of jobs take about half an hour once we're there, using pumps that are fine on a working forecourt and quiet enough to use outside a house after dark. Payment happens on the day, not upfront, and you receive the paperwork your insurer asks for: an engineer report and a VAT invoice. Wrong-fuel cover is part of plenty of insurance policies — so use the wait to check yours. ## About Hamilton itself Hamilton is a town situated on the banks of the River Clyde in South Lanarkshire, with a mix of flat and other types of housing.
