--- title: AdBlue in a Diesel Tank Fittleworth — Don't Start It canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/fittleworth-west-sussex/ location: Fittleworth county: West Sussex latitude: 50.960420 longitude: -0.562100 service: AdBlue in a Diesel Tank updated: 2026-10-20 --- # Fittleworth: AdBlue in the Diesel Tank? Leave It Off Motor off, ignition off: that's where you begin if AdBlue has got into your diesel tank. AdBlue is urea mixed in water. It does not burn, it does not mix with diesel, and the harm it does begins when your fuel system pulls it in. If the motor hasn't run yet, AdBlue in a diesel tank is usually emptied and thoroughly cleaned where the car stands around Fittleworth. Nothing comes before calling 0333 366 0103. ## What to do straight away, Fittleworth: AdBlue in your diesel tank Things to do: - Remove the keys, and that prevents anyone switching the electrics on. - Hazards on, if moving traffic is anywhere near. - Which product, and about what quantity? Hang on to the bottle or the receipt, and we will know. - Ring us from where you are. A postcode starting RH20 1, or the name of the closest street, brings the van to you without a search. Don't: - Shifting the vehicle even a few yards is no reason to fire up your engine. - Plenty of diesels power their fuel pump the instant your ignition comes on, so keep it off. - Adding extra diesel doesn't work: AdBlue separates out instead of thinning. - Any driving at all is to be avoided, even a short way along Lower Street. - Do not try to drain the car yourself at the kerbside. Rolling the vehicle away from the pumps is a job for attendants to help with, whichever Fittleworth forecourt you are on, the Elite Garages or any other. At your own driveway, do not touch it at all. ## AdBlue in a diesel tank: what it does Made for the exhaust, AdBlue has no place in your engine. From a dedicated tank it goes directly to your exhaust, cleaning what your engine emits. Nothing in it is supposed to pass through a fuel pump, and nothing in a fuel pump is built to handle it. Tipped in with your diesel, it keeps apart rather than blending — entirely different from fuel. It's heavier than diesel, so it sinks and collects at the bottom of your tank, which is where the pickup pulls fuel from. A vehicle filled on a driveway in Stopham overnight and left unstarted is the straightforward case. Nothing has sucked the AdBlue up so far — but once the engine turns, that's what is pulled first, straight from the bottom of that tank. After it is sucked in, the harm takes two forms. What remains when the water evaporates is urea, which turns into crystals: they settle in narrow passages and clog filters. On top of that, it eats at certain metals in a fuel system, and carries on until it's cleared out. Pipes carrying AdBlue spell harm overnight for a car sitting around Fittleworth. Just in your tank, it stays stable. And there is the water: it offers no lubrication to the components that rely on it most — the injection pump and every injector. ## Why AdBlue in a diesel is regularly more major than petrol Petrol pumped into a diesel on Murco's forecourt makes your fuel watery — that's the main problem. Mixed into the diesel and sitting unused, it's no threat at that stage; using the motor is the damage. The issue with AdBlue in a diesel is a completely unsuitable liquid. It doesn't burn, so it cannot simply be run through. Crystals and corrosion remain through the next fill, and AdBlue separates back from your diesel, so thinning it can't help. That is why the flush matters so much, and turning your key "to see" does more harm here than almost any other slip — in Coates or the centre of Fittleworth alike. With AdBlue, the good news is no separate from petrol. Emptying a tank is the simplest part on a fuel system, and without start-up, the AdBlue stays in it — wherever around West Sussex your car sits. ## How does AdBlue end up in a diesel tank in Fittleworth? No one means to do it. The AdBlue filler on many motors rests right next to your diesel filler, at times under the same flap, and the two caps can look alike in poor light. It mostly takes place at home, from a container grabbed on the journey home, rather than at the forecourt. The ways it takes place are few and familiar. Rushing, outside Fittleworth CofE Village School, after a warning light came on during the school run, someone refills the vehicle. Someone pours the bottle in outside their house, right off School Close, as the day ends. Another pattern: darkness, the car park by The Swan, and a driver opening that flap the first time. Rented motors, brand-new vehicles, company vehicles, or the second car in a family with both fuels: the least familiar cars get it the most. Same slip, same first response — keep it off — anywhere you happen to be in Fittleworth or the remainder of West Sussex. ## Started the motor with AdBlue in the diesel tank around Fittleworth? Then the tank is no longer where the AdBlue is. It has been pulled through the fuel filter and the fuel lines, and if your motor ran for any time, it has got to your high-pressure pump and the fuel injectors. Rough running, smoke, lost power, dashboard warnings or cutting out: any may show up, maybe midway across Fittleworth or returning from Birchwalk Wood. No starting it again to check: stop once safe, then switch it off. Each start pulls more of that through. Exit the M23, under 25 miles from Fittleworth, by the first junction and stop safely, not driving on. Each mile carries the AdBlue deeper in. That's why crossing Fittleworth to park near Fittleworth Free Church and a drive of under 15 miles towards Chichester are very different jobs. Approximately how far had it come? Tell us. Once the motor has been run, the flush takes in more, and all of it is done where your car has come to a stop. Very seldom does it leave lasting damage when it is noticed soon. ## Draining AdBlue in a diesel in Fittleworth: what it takes Anywhere it has stopped around Fittleworth — a filling station, a layby, a driveway, a road beside Fittleworth Village Hall — the van comes to your car. Three replies shape the job, and so first our engineers ask what went in, about what quantity, and if the motor has turned over. Right there, that tank is then drained, and both the polluted diesel and the urea leave at once. With AdBlue, more so than with petrol, the flush counts: the whole system is cleaned all the way through because what remains won't flush out by itself. Testing your car follows at the end, once fresh diesel is added and your filter is flushed or, where needed, swapped. Most of these jobs are a half-hour job once our technicians arrive, provided your motor hasn't run. The pumping gear is explosion-proof, and so a busy filling station is no issue, and it is hushed enough for a residential street after dark. The final step is to prime the system on clean diesel. Then we fire it up and you head off, whether from a parking bay outside Pulborough or a drive in Fittleworth. Before we go, our technicians check it is running properly with clean diesel in. The entire job is done where your car is, so it never has to be taken to a workshop. You receive a VAT invoice and an engineer report afterwards, which is what insurers ask for. ## About Fittleworth itself Fittleworth is a small village in West Sussex, situated on the banks of the River Rother at an elevation of around 22 metres.

What changes the cost is, first, whether the motor has run and for how long; then how much AdBlue went in; and then where the car is and whether a van can get to it safely, which is simpler on an open driveway than in a tight gap behind Fittleworth Church. For that in mind, every call from Fittleworth begins by asking the same trio — what went in, how much, whether it ran — ahead of a quote. With those replies, the range shrinks to a single fixed number. Before a van heads out, you hear the price on the phone. Then payment is on the day, by card or by phone, with nothing upfront. Check your policy while we are on the way: plenty carry misfuelling cover. ## Fittleworth: still next to the vehicle? Leaving the vehicle alone is, then, the most useful move you can do. Keys out, motor off, ignition off. Ring 0333 366 0103 and tell us it's AdBlue, about how much, and if it's run. Petrol in Diesel takes it from there, in Fittleworth or anywhere around West Sussex.
