--- title: AdBlue in a Diesel Tank Wray Common — Don't Start It canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/wray-common-surrey/ location: Wray Common county: Surrey latitude: 51.239660 longitude: -0.189240 service: AdBlue in a Diesel Tank updated: 2026-10-23 --- # AdBlue in the Diesel Tank in Wray Common? Keep It Switched Off With AdBlue in the diesel tank, your ignition stays off and so does the motor. AdBlue is urea mixed in water. Unlike fuel, it neither ignites nor mixes, and nothing starts until the motor pulls it round. Caught before your engine has run, AdBlue in a diesel tank is normally a drain and a thorough flush, done where your car is around Wray Common. Before you do anything else, call 0333 366 0103. ## Those opening minutes: AdBlue in the diesel tank around Wray Common Do: - So nobody can turn the ignition on, take the keys away. - Hazards on, if moving traffic is at all near. - Which product, and about what amount? Hang on to the bottle or the receipt, and we will know. - Ring us from where you are. A postcode starting RH2 0, or the name of the nearest street, brings our van to you without a search. Not to do: - Not even briefly, and not to shift the vehicle: the motor remains off. - Turning the key to ignition alone sets your pump going on plenty of diesels. Avoid it. - No extra fuel on top. The AdBlue won't mix, so it's pointless. - Keep the vehicle where it is instead of driving it anywhere, even a short way along Howard Court. - Do not try to drain the car yourself at the roadside. At a forecourt around Wray Common, whether it's the BP or another one, ask the staff to help you push your car away from the petrol pump. If you are on your own drive, leave the car precisely where it sits. ## What does AdBlue do in a diesel tank? The engine isn't what AdBlue is made for; your exhaust is. It goes into its own tank and is sprayed into your exhaust gas to clean it. 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 really differently from fuel. It doesn't mix in. It drops, since it's denser than diesel, and settles low where the intake takes its supply from. Simplest of all: a vehicle that had AdBlue in St Johns overnight and hasn't been started since. The AdBlue waits at the base of the tank, undrawn — though it would be the first thing through if your motor runs, ahead of any diesel at all. Two kinds of damage follow from there. It attacks some metals found in fuel components, attacking any part it touches till it's removed from the system. And when the water evaporates, the urea turns into crystals that clog filters and settle in narrow channels. A vehicle left sitting in Wray Common with AdBlue already in its lines is worse by the morning; one with AdBlue only in its tank is not. The water in it causes harm of its own: the high-pressure fuel pump and the injectors depend on diesel to lubricate them, and water gives them nothing. ## Why is AdBlue in a diesel frequently the bigger issue? Put petrol in a diesel at the Esso and you have a problem of thin fuel. Damage only comes from driving on it. Mixed into your diesel and left in that tank, it causes nothing. AdBlue in a diesel is an issue of the wrong substance altogether. Not burning, it can't just be run through. Nor can it be thinned, because it splits back out — and the next tankful will not clear away deposits or corrosion. So the flush matters for more here, and turning your key "to see", in the heart of Wray Common or out in Coles Meads, costs more than nearly any other slip. The same good news applies as with petrol. Not started? Then the AdBlue sits just inside that tank, the simplest bit of the entire system to empty, anywhere the vehicle has stopped across Surrey. ## AdBlue in a diesel tank around Wray Common: how it ends up there Nobody means to do it. The AdBlue filler on plenty of vehicles rests right next to the diesel filler, at times under the same flap, and the two caps can look alike in poor light. Mostly it is not the forecourt: a driver buys a bottle driving home and tips it in outside the house. The ways it happens are few and familiar. Halfway through the morning drop-off, the dashboard flags it up, and outside Hatchlands Primary the refill is hurried. Someone tips the container in at home, right off The Cedars, as the day ends. Or the vehicle is topped up in the car park outside The Roe Deer, in poor light, by someone who has never opened that flap before. The least known cars see it the most — rentals, new ones, company ones, and the other car of a home with one of each fuels. Keep it switched off: that's the first response to an identical mistake, wherever around Wray Common or the rest of Surrey you happen to be. ## Wray Common: started the engine with AdBlue in your diesel tank? Then your tank is no longer where the AdBlue is. It's been sucked through the filter and the fuel lines, and if your engine ran for any time, it has reached the high-pressure fuel pump and the injectors. Watch for lumpy running, exhaust smoke, lost power, warnings on your dash, or a stall — coming back from the green space at the edge of the village, perhaps, or part way across Wray Common. When you safely can, stop and switch it off — without restarting to see. More of it is pulled through with each start. Wray Common sits under 3 miles from the M25; if you were on it, leave by the first junction and pull up safely rather than carrying on. Every mile carries the AdBlue further into your system. That's why crossing Wray Common to park beside Roman tile kiln and a drive of under 25 miles towards Westminster are such different jobs. Tell us roughly how far it had come. Wherever the car came to a halt is where all of it gets done, even with more to rinse out after your engine has been running. Caught early, it very seldom leaves long-term damage. ## Wray Common: how AdBlue is drained from a diesel Our engineers come to your car, wherever it has stopped in Wray Common: a side street close to Reigate Meeting House (Quaker), a drive, a lay-by or a forecourt. The work rests on three answers, which our technicians ask for first — what got in, the amount, and whether your engine has run. The polluted diesel and the urea come out together when your tank is emptied, right there. Residue from AdBlue won't wash away by itself, and so the fuel system gets a full flush, which matters far more with urea than with petrol. Testing your vehicle comes last, after fresh diesel is added and your filter gets cleaned or, where needed, swapped. If the motor hasn't run, most jobs take about half an hour once our engineers arrive. Explosion-proof pumps mean a busy forecourt safe to work on, and they run quiet enough to spare the street at night. Finally, the fuel system is bled with new diesel. Starting the engine comes next, and then you drive off from where your car is parked, by Reigate or on a drive in Wray Common. We make sure it runs smoothly on fresh diesel before we leave. No garage is required at any point, with the entire job done then and there. Your insurer will want an engineer's report and your VAT invoice — each handed over afterwards. ## About Wray Common Wray Common is a locality in Surrey, situated near the River Mole and close to the towns of Reigate and Redhill.
