--- title: Midhurst: AdBlue in a Diesel Tank, Explained canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/midhurst-west-sussex/ location: Midhurst county: West Sussex latitude: 50.985510 longitude: -0.740030 service: AdBlue in a Diesel Tank updated: 2026-10-12 --- # Avoiding AdBlue in a Diesel Tank in Midhurst: Why It Happens Keep your motor and ignition off and phone 0333 366 0103 now — the rest can wait when AdBlue is already in your diesel tank. Around Midhurst, finding it before your motor turns normally leaves a drain and a thorough flush where it stands. If you are reading before it has happened, the remainder of this page is about why it takes place and how to make sure it doesn't. ## Two fillers, two tanks: AdBlue in a diesel car Plenty of modern diesels around Bepton Common, as well as Midhurst, run on two fluids; the engine takes just your diesel. Its own tank holds it, and from there it goes to your exhaust, where a spray cleans the fumes. Separate tanks, different fillers. Other cars put the AdBlue filler in the boot or under the bonnet; a lot of others have the two together under one flap. Diesel goes in on every forecourt call-out, again and again. A driver who has to stop and think where it goes normally fills the AdBlue side, from a bottle, and far less often. That gap is where the slip lives. ## Midhurst: how AdBlue in the diesel tank takes place Carelessness seldom explains it. What does is three things coming up at once. The warning comes first. As AdBlue runs low the car tells you, and if it runs out altogether, the car goes into limp mode. So the top-up is done in a hurry: on a drive off Petersfield Road before work, or in the car park at The Bricklayer's Arms on the way home. Then your car is unfamiliar. A hire car, a new car or a company car puts the fillers where your last one didn't, and the hand reaches for the cap it would have used on the old one. Nothing halts the pour once it has started, since a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. It's a few seconds, be it out in West Lavington or right in the heart of Midhurst. ## Telling the AdBlue filler from your diesel filler A couple of seconds is all these take — so check them before you tip anything, on a driveway in Woolbeding or a forecourt around Midhurst. - Read the cap rather than going by where it sits: AdBlue ones are commonly blue or marked "AdBlue", and diesel ones usually aren't. - On plenty of cars, size tells: AdBlue gets the smaller filler neck. - Lift the filler flap and look for a label — many vehicles mark which belongs in each inlet right there. - The handbook. If the filler is not by the diesel cap, it's in your boot or under the bonnet, and the handbook says which. - The person who drove it last. On a hire or company car collected from somewhere like the car park at Liphook, ask before you leave, not when the light comes on. ## AdBlue top-ups that never reach your diesel tank Wherever across West Sussex the light comes on, this is a routine for the day. - Pull in somewhere level, engine off, with time to spare — not hurried on the side of Bepton Road. - Silly as it sounds, speaking "AdBlue" out loud while you unscrew the cap works — after you have found the filler and read it. - Leave the diesel cap on. If both sit under one flap, check your diesel cap is still closed before you lift the bottle. - Using the bottle's own spout, tip slowly — and stop when it's full or the bottle is empty. - Close the cap and check once more. Make sure the diesel cap was never opened. Only then start your car. If at stage two or three you find you have already poured into your diesel side, stop there. Step five is off limits. ## Put AdBlue in the diesel tank around Midhurst already? Don't start your engine: that's how the short order of things starts. The fuel pump runs on many diesels the moment the ignition is switched on — so keep it off. Filling up with diesel will not weaken it: instead, AdBlue drops to the base of your tank, right where fuel is drawn from. If you're at a forecourt, whether it is the Esso or the BP, ask the attendants to help roll the vehicle away from the petrol pump. On your own drive in Midhurst? Then the car remains put. Where your engine has been run already, pull over somewhere safe then switch it off. The next exit is the place to come off if you're on the Waterlooville Bypass, under 15 miles from Midhurst. Tell us about how far it went: a run towards Chichester, under 15 miles away, is a bigger job than a short hop across Midhurst. ## When our technicians arrive in Midhurst, what occurs? Our engineers come to the car wherever it has stopped, whether that is outside Midhurst CofE Primary School, close to Midhurst Library or on your own driveway. Our engineers ask what got in, roughly how much, and whether it has run, since those answers settle this work and our quote. Nobody sets off before you've heard our price by phone. The system is then rinsed thoroughly, once the tank is drained. With AdBlue that counts more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, so it does not wash out on its own. After the filter has been cleaned — or renewed, if required — clean diesel goes in, and then your vehicle gets tested. The motor is fired up next and tested to confirm it runs correctly, all before our technicians go. If the motor has not run, most jobs take about half an hour once we are there, using pumps that are safe on a busy forecourt and quiet enough to use outside a house after dark. The insurer usually wants an engineer's report and the VAT invoice, and you get both once this job is done. Payment comes on the day, with no deposit. It's worth looking at your insurance while we travel to you: misfuelling cover comes with plenty of policies. ## About Midhurst itself Midhurst is a town situated in the western part of West Sussex, on the River Rother, with a mix of old and new buildings.
