--- title: AdBlue in a Diesel Tank Lower Somerton? Read This canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/lower-somerton-somerset/ location: Lower Somerton county: Somerset latitude: 51.051660 longitude: -2.725550 service: AdBlue in a Diesel Tank updated: 2026-10-26 --- # How It Occurs and How to Prevent It: AdBlue in a Diesel Tank in Lower Somerton If AdBlue is already in your diesel tank, stop reading for a moment: leave the engine and your ignition off and ring 0333 366 0103. A drain and a thorough flush, done right where the car sits around Lower Somerton, is usually what it needs when caught before your engine runs. The rest of this page covers why it occurs and how to ensure it does not — useful if you are reading before it has happened. ## Why does AdBlue in a diesel motor need its own filler? Many newer diesels in Behind Berry, as well as Lower Somerton, carry on two fluids; your engine takes only your diesel. Stored in a tank of its own, AdBlue is sprayed into your exhaust stream and cleans it. There's a filler on every tank. Some motors put the AdBlue filler in your boot or under the bonnet; plenty of others have both together under one flap. At the pump, your diesel side is topped up constantly. Much less frequently, the AdBlue side gets topped up — mostly from a bottle, by someone working out where it goes. The mistake lives in that gap. ## How does AdBlue in the diesel tank take place in Lower Somerton? Three things tend to come together, and carelessness is seldom one of them. Hurry follows from the warning. The vehicle warns you as AdBlue runs low, and a dry tank puts the vehicle into limp mode — so the top-up happens quickly, before work on a driveway off Catsgore Road, or on the way home in the car park at The Globe Inn. Then the vehicle is unfamiliar. A hire car, a new vehicle or a company car puts the fillers where your last one didn't, and your hand reaches for the cap it would have used on the old one. A spout-topped bottle finds no resistance at a diesel filler any more than at an AdBlue one. So the tip, once begun, carries on. Whether it happens in The Millands or the middle of Lower Somerton, it is the same few seconds. ## Telling the AdBlue filler from the diesel filler A few seconds is all these take — so run through them before you pour anything, on a driveway in West End or a forecourt in Lower Somerton. - Check the cap instead of going by where it sits: AdBlue caps are often blue or marked "AdBlue", and diesel ones normally are not. - On plenty of cars, the size tells: AdBlue gets the smaller filler neck. - Open the filler flap and check for a label — many motors show what goes in which 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. - Check with the person who drove it last — before you leave, not when the light comes on — if you collect a hire or company car from somewhere like the car park outside Yeovil Pen Mill. ## AdBlue top-ups that never reach your diesel tank Wherever across Somerset the light comes on, here is a routine for that day. - Park and switch off. Not on a slope, not with the engine running, and not in a rush on the side of Pesters Lane. - Find the AdBlue filler, read the cap, and say the name "AdBlue" aloud as you unscrew it. It sounds silly. It works. - If both sit under one flap, check the diesel cap is still closed before you lift the bottle — and leave the vehicle on. - Pour slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty. - Close the cap, and look again — making sure your diesel cap stayed shut the whole time. Only then, start the vehicle. Stop there if you find, at step two or three, that you've already poured into your diesel side. Don't go on to step five. ## AdBlue in your diesel tank already, in Lower Somerton? The short order of things, beginning with no starting your motor. Do not switch your ignition on; on many diesels that alone runs the fuel pump. Do not top up with diesel to thin it: AdBlue doesn't mix with diesel, it sinks to the bottom of that tank, where your fuel is sucked from. If you're at a forecourt, whether it's the Esso or the Texaco, ask the staff to help push the vehicle clear of the pump. If you're on your own drive around Lower Somerton, leave the vehicle where it sits. Stop as soon as it is safe and switch off, if the motor has already run. Come off the M5 — under 15 miles out of Lower Somerton — at the next exit. Roughly how far did it go? Hopping across Lower Somerton is smaller work than a trip of under 15 miles towards Wells, and so say. ## What occurs when our technicians get there around Lower Somerton Our engineers come to your car wherever it has stopped, whether that is outside King Ina Church of England Academy, close to The Old Town Hall or on your own drive. Both the work and the quote depend on three answers — which fluid, what amount, and if it's run — so our technicians ask. No one sets off until you have had our price by phone. The system is then flushed thoroughly, after the tank is cleared. With AdBlue that matters more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, and so it doesn't wash out on its own. After the filter has been flushed — or renewed, if required — clean diesel goes in, and finally the vehicle is tested. Then we start the engine and make sure it runs properly before leaving. Most jobs are finished in about half an hour once our engineers get there, as long as your engine hasn't run — and the pumps our engineers use are fine on a busy forecourt yet quiet at night beside a house. The insurer usually wants the engineer's report and your VAT invoice, and you get both once this job is done. Payment is on the day, with no money upfront. Plenty of insurance policies include misfuelling cover, and so it is worth checking yours whilst we're on the way. ## About Lower Somerton and where it is Lower Somerton is a suburban area situated on the riverside in Somerset, with an elevation of 26 metres.
