In Batmans Hill, catching it before the engine turns usually leaves draining and a thorough flush on the spot. Reading before the event? Then the rest explains why it happens and what to stop it happening at all. ## Why does AdBlue in a diesel car need its own filler? Plenty of modern diesels on the roads around Batmans Hill and Princes End carry two liquids, not one. Diesel goes to your motor. The exhaust, not your engine, is where AdBlue ends up: sprayed into the gas to clean them, from a separate tank. Each tank has its own filler. Many of cars share a single flap for both, whereas some move the AdBlue filler to your boot or under the bonnet. Filling the diesel side at the pump happens constantly. Far less frequently, the AdBlue side is filled — mostly from a bottle, by someone working out where it goes. It is in that gap that the mistake happens. ## Batmans Hill: how AdBlue in your diesel tank occurs Three things tend to come together, and carelessness is seldom one of them. First, the warning. Low AdBlue brings a message from the car, and letting it run out leads to limp mode — hence a rushed top-up, maybe before work off Dereham Walk, or outside The Rocket Pools on the way home after work. Unfamiliar vehicles are second, too. Hire cars, new vehicles and company cars place their fillers in new places, and the hand reaches for the cap used on the old one. A spouted bottle finds no resistance at a diesel filler any more than at an AdBlue one. And so the tip, after begun, carries on. Whether it takes place in Hall Green or the middle of Batmans Hill, it's the same few seconds. ## The AdBlue filler and your diesel filler: telling them apart Be it a Batmans Hill forecourt or a drive over in Highfields, spend a couple of seconds on these before any is poured in. - Position can mislead; the cap doesn't. AdBlue caps are often blue or bear the name "AdBlue" — diesel ones usually don't. - Plenty of vehicles fit AdBlue the smaller filler of the two. - The flap. Look inside your fuel flap for a label. Many motors say there which fuel goes where. - In your boot or under the bonnet: that's where your filler is if it's not by the diesel cap, and the handbook says which. - The person who drove the vehicle last. On a hire or company car picked up from somewhere like the car park outside Coseley, ask before you leave, not when the light comes on. ## AdBlue top-ups that never reach the diesel tank For the day the warning appears — anywhere it is around West Midlands — a routine to use. - Park and switch off. Not on a slope, not with your engine running, and not in a rush on the side of Wilkinson Avenue. - Say "AdBlue" out loud as you unscrew the cap, after finding the AdBlue filler and read it. Silly, yes, but it does the trick. - The diesel cap stays on. Where both share a flap, make sure it is closed before the bottle comes up. - Tip slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty. - Only then, start your car: close the cap, check once more, and make sure your diesel cap was never opened. Find at step two or three that it's already gone into the diesel side? Then stop just there. Don't carry on to stage five. ## Put AdBlue in the diesel tank around Batmans Hill already? Brief order, then. Top of it: the engine stays off. Leave your ignition off as well, because on plenty of diesels switching it on by itself runs your fuel pump. Don't top up with diesel to dilute it: AdBlue doesn't mix with diesel, it sinks to the bottom of that tank, where the fuel is pulled from. The attendants at Asda, Morrisons or another forecourt will normally help to push the vehicle away if you ask. Leave it where it is if you're on your own driveway around Batmans Hill. Where your motor has run by now, pull over safely and turn the car off. On the M6, under 3 miles from Batmans Hill, that means the next exit. Distance matters — a quick hop across Batmans Hill is a smaller job than driving under 5 miles towards Wolverhampton — so tell us about how far it went. ## When we turn up in Batmans Hill, what occurs? Our engineers come to the car wherever it has stopped, whether that is outside Wilkinson Primary School, near St Martin or on your own drive. Both the work and the quote rest on three answers — which liquid, which quantity, and if it has run — so our technicians ask. During the call itself, you hear the price — ahead of anything else. Your system is then rinsed thoroughly, after that tank is drained. Not like petrol, AdBlue forms crystals and eats at certain fuel-system metals, and none of that washes away by itself. Hence it matters more. After the fuel filter is cleaned — or replaced, where needed — clean diesel is added, and finally the car gets tested. The engine is started next and checked to make sure it runs smoothly, all before our technicians leave. Most jobs are finished in roughly half an hour after our engineers arrive, as long as the motor hasn't run — and the pumps our technicians use are safe on a busy forecourt and quiet after dark beside a house. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Misfuelling cover is part of many insurance policies — and so make use of the wait to look at yours. ## About Batmans Hill, briefly Batmans Hill is a suburban area located on the outskirts of Wolverhampton, near the riverside and approximately 3.5 miles from the city centre.
