A drain and a thorough flush, carried out right where the car stands around Blakedown, is usually what it needs if caught before your engine runs. If you're reading before it has happened, the rest of this page is about why it happens and how to make sure it does not. ## AdBlue in a diesel car: two tanks, two fillers Diesel goes to your engine — yet plenty of current diesels seen about Blakedown and Yieldingtree hold another fluid as well. Stored in a tank of its own, AdBlue is fed into the exhaust stream and cleans it. There's a filler for every tank. Under one flap, next to each other: that's the arrangement on many vehicles. Elsewhere, AdBlue's filler is under the bonnet or in the boot instead. At the petrol pump, the diesel side is topped up all the time. Someone who has to stop and work out where it goes normally fills the AdBlue side, from a bottle, and far less commonly. The mistake grows in the gap between them. ## Blakedown: how AdBlue in the diesel tank takes place Rarely is it carelessness: normally three things line up. First, the warning. Low AdBlue brings a message from the vehicle, and running dry leads to limp mode — hence a rushed top-up, perhaps before work off Forge Lane, perhaps outside The Old House at Home on the way home after work. New-to-you motors are next, too. Hire cars, new cars and company vehicles put their fillers differently, and the hand reaches for the cap it used on the old one. No part stops the tip once it has started, since a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. The same few seconds settle it, in the middle of Blakedown or out in Churchill. ## Which filler is for AdBlue, and which for diesel? A couple of seconds is all the checks take — so check them before you tip anything, on a drive in Barnettbrook or a forecourt around Blakedown. - Check the cap rather than going by where it sits: AdBlue caps are frequently blue or marked "AdBlue", and diesel ones normally aren't. - On many motors, the size tells: AdBlue has the smaller filler neck. - Look inside the fuel flap: plenty of motors have a label there showing which fuel goes where. - The handbook. If your 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 the nearest station? Ask the person who drove the vehicle last before leaving, rather than once the light goes on. ## Topping up AdBlue without it reaching your diesel tank When the light comes on, anywhere in Worcestershire, follow this routine. - Turn off after you park — flat ground, engine off, and not in a rush by Belbroughton Road at the roadside. - Daft as it sounds, saying "AdBlue" aloud while you unscrew the cap works — once you have found your filler and read the cap. - If both sit under one flap, check the diesel cap is still closed before you lift the bottle — then leave the car on. - Tip slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty. - Shut the cap, and check again — confirm the diesel filler remained closed throughout. After that, start the car. If at stage two or three you find you have already poured into your diesel side, stop there. Skip step five altogether. ## Put AdBlue in the diesel tank around Blakedown already? Short list, then. Top of it: the motor remains unstarted. The fuel pump starts on plenty of diesels the moment the ignition goes on — so keep it off. AdBlue doesn't mix with diesel — it sinks to the bottom of your tank, where the fuel is sucked from — so do not top up with diesel to thin it. The staff at Shell, Texaco or any forecourt will usually help to push the vehicle away if you ask. On your own drive around Blakedown? Then your car remains put. Stop as soon as it is safe and switch off, if the motor has already run. On the M5, under 10 miles from Blakedown, that means the next junction. Tell us about how far it went: a run towards Birmingham, under 15 miles away, is a bigger job than a short hop across Blakedown. ## When our technicians get there around Blakedown, what occurs? Our van reaches the car wherever it stopped — your own drive, near St James the Great, or by Blakedown CofE Primary School. Both the work and the price rest on three answers — which fluid, what quantity, and whether it's run — so our technicians ask. No one heads out before you have had the price over the phone. Then that tank is drained and the system flushed thoroughly. Unlike petrol, AdBlue forms crystals and attacks certain fuel-system metals, and none of that clears out unaided. Hence it matters more. Your filter is cleaned, or replaced where it needs to be; clean diesel goes in; and your car is tested. The engine is started next and tested to make sure it runs correctly, all before our engineers head off. Unrun vehicles usually mean a half-hour visit from the moment we arrive. The kit is safe on a busy forecourt, and hushed enough for a driveway after dark. The insurer will ask for an engineer's report and the VAT invoice, and both are yours at the end. Payment is on the day, with no money upfront. Before we get there, take a look at your insurance documents; many carry cover for misfuelling. ## About Blakedown itself Blakedown is a village in Worcestershire, situated in the West Midlands region of England, with a population of around 1448 people.
