--- title: Don't Start It: AdBlue in a Diesel Tank Bigges Main canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/bigges-main-tyne-and-wear/ location: Bigges Main county: Tyne and Wear latitude: 54.997670 longitude: -1.548220 service: AdBlue in a Diesel Tank updated: 2026-10-14 --- # Bigges Main: AdBlue in the Diesel Tank? Leave It Off With AdBlue in the diesel tank, your ignition remains off and so does your engine. In plain terms, AdBlue is simply urea in water. It does not burn, it doesn't mix with diesel, and the harm it does starts when your fuel system pulls it in. In Bigges Main, AdBlue in a diesel tank caught before your engine runs usually comes down to a drain and a thorough flush, right where the car is. First, ring us on 0333 366 0103. ## Bigges Main, AdBlue in your diesel tank: what to do at once Do these: - Pull the keys out, so nobody switches the ignition on. - If you are anywhere near moving traffic, put the hazards on. - Hold on to your receipt or the empty bottle, and so you can tell us what went in and roughly how much. - Call just where you are. Say a NE28 8 postcode or the nearest street name, and no one has to hunt for you. Never do these: - Not even for a second, and not to roll the car: your engine stays off. - Don't switch your ignition on. On plenty of diesels that alone runs the fuel pump. - Don't top up with diesel to dilute it. AdBlue does not dilute in diesel; it separates out. - Any driving at all is to be avoided, including a short way along Cheshire Gardens. - Do not try to drain it yourself at the kerbside. Rolling your vehicle away from the island is a job for staff to help with, wherever Bigges Main forecourt you're on, the Esso included. On the drive, the vehicle stays just as it is. ## AdBlue in a diesel tank: what it does The engine isn't what AdBlue is made for; your exhaust is. Kept in a separate tank, it's injected into the exhaust to clean the fumes. Nothing in it is supposed to pass through a fuel pump, and nothing in a fuel pump is designed to handle it. Inside a diesel tank it behaves very differently from fuel. It does not mix in. The pickup takes fuel from the deepest part of your tank, and that is just where AdBlue settles: as it is denser than diesel, it sinks. When your pump runs, the AdBlue is first to go through. Before then it sits beneath the diesel, and that is why a vehicle topped up in Holy Cross last night and never switched on remains the simple one, provided nobody touches the key. From there it does two kinds of harm. It attacks some metals found in fuel components, working on whatever it touches until it is cleared from the system. And when the water goes, the urea turns into crystals that block filters and settle in tiny passages. By daybreak, a car parked in Bigges Main with AdBlue through its pipework gets worse; where it's only inside your tank, nothing changes. Then there's the water: it brings no lubrication to the parts that rely on it most — the high-pressure pump and each injector. ## Why is AdBlue in a diesel regularly the bigger fault? Petrol put into a diesel on Carville Service Station's forecourt makes the fuel watery — that is the main issue. It mixes with the diesel, and whilst it is in your tank it does no damage; the harm comes from running your motor on it. With AdBlue in a diesel, the fluid itself is plainly the wrong one. It does not burn, so it cannot simply be run through. Deposits and corrosion remain through the next fill, and AdBlue separates back from the diesel, so thinning it won't help. Hence the flush matters so much, and trying your engine "to see" does more harm here than nearly any other slip — in High Heaton or the heart of Bigges Main alike. The good news is the same as with petrol. Wherever around Tyne and Wear your vehicle has stopped, an unstarted motor means the AdBlue still inside the tank: the easiest bit of a fuel system to empty. ## Bigges Main: how AdBlue ends up in a diesel tank Many vehicles place the AdBlue filler beside the diesel one, now and then behind a single flap, and in dim light the two may look the same. Nobody means it. Mostly it's never the forecourt: a driver buys a container driving home and tips it in at home. A couple of familiar ways account for the majority of them. The top-up is hurried outside St Columba's Catholic Primary School, Wallsend, after the dash lit up with a warning as the kids were taken off. A bottle is poured in at the end of the day on a drive just off Devonshire Gardens. Or someone unfamiliar with that flap refills your vehicle after dark, parked in the car park by The Dorset Arms Hotel. Hired cars, new vehicles, company vehicles, or the spare vehicle in a home with both fuels: the least familiar cars see it most. An identical slip, same first step — keep it switched off — wherever you are in Bigges Main or the remainder of Tyne and Wear. ## AdBlue in the diesel tank in Bigges Main, and your engine started? Then the AdBlue has left that tank. The filter and pipework have had it sucked through, and any running carries it on to the injection pump and every injector. Perhaps returning from Wallsend Golf Course Centurion Park, or midway across Bigges Main, your engine may go rough, smoke, lose pace, light up the dash or cut out. Once safe, pull over and turn everything off — without turning it on again to test. More of it is pulled through with each start. Leave the A167(M), under 3 miles from Bigges Main, by the next junction and park somewhere safe, rather than carrying on. Mileage counts: each mile carries the AdBlue deeper in, so driving towards Newcastle upon Tyne, under 3 miles away, gives a far larger job than hopping across Bigges Main to the car park by St John the Evangelist. Let us know roughly how far it had come. Once the motor has been run, the flush covers more, and all of it is done where the car has come to a stop. Caught quickly, it very seldom leaves lasting damage. ## What does an AdBlue drain on a diesel involve around Bigges Main? A road by Saint Bernadette, a driveway, a lay-by or a forecourt: wherever your vehicle has stopped around Bigges Main, our engineers travel to it. Which fluid got in, roughly how much, and whether your motor has turned over: our engineers ask first, because those shape the work. The contaminated diesel and the urea come out together after that tank is emptied, right there. With AdBlue, far more than with petrol, flushing matters: the whole system is cleaned right through because what remains will not wash out unaided. A test of your vehicle comes at the end, after fresh diesel is added and the filter gets cleaned or, where needed, replaced. The majority of these jobs are a half-hour visit once our engineers arrive, provided the engine hasn't run. The pumping gear is explosion-proof, and so a busy filling station is no fault, and it is hushed enough for a residential street after dark. The last step is to prime the system on clean diesel. Firing it up comes next, and then you set off from where your car is parked, at Manors or on a driveway in Bigges Main. Our engineers confirm it runs properly on new diesel before we leave. No garage is required at any point, with the whole job done then and there. The insurer is likely to want an engineer's report and the VAT invoice — each handed over afterwards. ## About Bigges Main and where it is Bigges Main is a suburban area located on the riverside in Tyne and Wear, with a mix of semi-detached housing and local amenities.

If you're near a boundary, or somewhere hard to describe, ring and ask rather than guessing.

What changes the price is, first, whether the motor has been running and for how long; then how much AdBlue went in; and finally where your car is and whether a van can get to it safely, which is simpler on an open driveway than in a tight space behind Baitul Ata. For that reason, each enquiry from Bigges Main begins with the same trio — what was put in, what quantity, if it ran — before any figure. Those answers turn a range into a straight quote. Before a van sets off, you hear the quote by phone. Then payment is on the day, card or by phone, with nothing in advance. While the van is on the way, dig out your insurance: many include misfuelling. ## In Bigges Main and still alongside the car? Not touching the car is, right now, the most useful thing you can do. Ignition off, engine off, keys out. Call 0333 366 0103 then tell us it is AdBlue, about how much, and if it's run. Petrol in Diesel takes it from there, around Bigges Main or anywhere around Tyne and Wear.
