A drain plus a full flush, carried out right where your car stands in Dalginross, is normally what it needs if caught before your engine runs. The rest of this page covers why it happens and how to make sure it doesn't — handy if you're reading before it has happened. ## Why does AdBlue in a diesel car need its own filler? Many newer diesels in Tullybannocher, like those in Dalginross, run on two fluids; your motor gets just your diesel. The exhaust, not the engine, is where AdBlue goes: dosed into the gas to clean them, from its own tank. Each tank has its own filler. Under one flap, side by side: that's the arrangement on a lot of cars. Elsewhere, AdBlue's filler sits under the bonnet or in your boot instead. Filling your diesel side at the petrol pump goes on constantly. Someone who has to stop and think where it goes usually fills the AdBlue side, from a bottle, and much less commonly. It is in that gap that the error happens. ## AdBlue in your diesel tank in Dalginross: how it happens Three things tend to line up, and carelessness is rarely one of them. 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 driveway off Gowanlea Road before work, or in the car park at the pub in the village on the way home. The old car's cap is where the hand goes — but a rental car, a new vehicle or a company car keeps the fillers elsewhere. That's the second thing: a new vehicle. A spouted bottle finds no obstacle at a diesel filler any more than at an AdBlue one. So the tip, after begun, carries on. Polinard or the middle of Dalginross: it is the same few seconds in both. ## How to tell the AdBlue filler from the diesel one A couple of seconds is all the checks take — so check them before you pour anything, on a drive in Cultybraggan or a forecourt around Dalginross. - The cap. The AdBlue cap is commonly blue, or marked "AdBlue". The diesel cap normally isn't. Read it instead of going by position. - Look at the size: the smaller filler neck is, on plenty of motors, the AdBlue one. - Look inside your fuel flap: many motors carry a label there saying which fuel goes where. - In your boot or under the bonnet: that is where the filler sits if it's not by the diesel cap, and the handbook says which. - Check with the person who drove it last — before you leave, not when the light comes on — if you pick up a hire or company car from somewhere like the car park outside Gleneagles. ## AdBlue top-ups that never reach your diesel tank A routine for the day the light comes on, wherever in Perth and Kinross that is. - Switch off after you park — flat ground, engine off, and not in a rush beside Aros Field East on the verge. - Silly as it sounds, saying "AdBlue" out loud as you unscrew the cap works — after you have located your filler and read it. - The two under a single flap? So confirm the lid on the diesel filler stays shut ahead of raising the bottle. - Stop when the tank fills or the bottle is empty; before that, tip gently using its built-in spout. - Only then, start the vehicle: close the cap, check a second time, and make sure the diesel cap was never opened. Find at the second or third stage that AdBlue went into the wrong tank? That's where you stop. Don't go on to step five. ## Put AdBlue in the diesel tank in Dalginross already? The short order of things, beginning with no starting your engine. On plenty of diesels your ignition alone runs the fuel pump, and so don't switch it on. AdBlue does not mix with diesel — it sinks to the bottom of the tank, where your fuel is sucked from — so don't top up with diesel to thin it. The attendants at the nearest petrol station, another forecourt nearby or another forecourt will normally help to push the vehicle away when you ask. Your own drive in Dalginross is where it should stay. Already run? Stop once it's sensible, then turn off. The next exit is where to come off if you are on the M9, under 15 miles from Dalginross. Tell us roughly how far it went: a run towards Stirling, under 25 miles away, is a bigger job than a short hop across Dalginross. ## Dalginross: what takes place when our technicians arrive Our engineers come to your car wherever it has stopped, whether that is outside the local primary school, close to Dalginross Roman fort or on your own driveway. The answers settle this work and the quote, and so we ask what was put in, about how much, and whether it's run. You get that price on the phone, before anybody sets off. Emptying that tank comes next, followed by a full flush of the fuel system. Not like petrol, AdBlue leaves crystals and eats at certain fuel-system metals, and neither clears away unaided. That is why it counts more. Once the filter is flushed — or renewed, where required — clean diesel is added, and then your vehicle gets tested. After that our technicians fire it up and check it runs smoothly before we go. If the engine hasn't run, the majority of jobs take about half an hour once we are there, using pumps that are fine on a busy forecourt and quiet enough to use outside a house after dark. Payment is 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 many insurance policies — and so use the wait to look at yours. ## About Dalginross and where it is Dalginross is a suburban area situated on the riverside in Perth and Kinross, with a mix of detached housing and a population of around 1403 residents.
