--- title: What Now? AdBlue in a Diesel Tank Thorpe Lea canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/thorpe-lea-surrey/ location: Thorpe Lea county: Surrey latitude: 51.421830 longitude: -0.536480 service: AdBlue in a Diesel Tank updated: 2026-10-17 --- # Thorpe Lea: AdBlue in the Diesel Tank? Find Your Situation What to do about AdBlue in a diesel tank comes down to one thing more than any other: if your engine has been run since it was put in. Wherever your car is — Thorpe, Thorpe Lea — don't run a motor that hasn't run yet. Leave your motor and the ignition off then call 0333 366 0103; it's usually a drain and a thorough flush, done where the car is in Thorpe Lea. Stop the minute you safely can then switch off, if it has been run. The job is bigger, but the first step is the same. Anywhere in Surrey it happened, one of the situations below matches yours. ## On a Thorpe Lea forecourt with AdBlue in a diesel Imagine it: stood by the pump, holding the bottle, you realise the filler you opened wasn't the right one. Be it Shell, Esso or somewhere else in Thorpe Lea, the case is the same. What it means: this is the ideal spot to find out. The AdBlue is inside the tank and nowhere else. Nothing has pulled it in. Freeing the pump is no reason to run it — and so do not get back in. Three jobs: a shove into a bay with the staff assisting, the bottle saved, and a ring to us from the forecourt. Can't move the vehicle by the pump? Our explosion-proof equipment keeps a live forecourt sensible, and so it can be drained in place. ## AdBlue in the diesel tank at home in Thorpe Lea For days the dashboard had been warning you. Bought a container, poured it in at home, recycled the empty — and only then checked the cap a second time, too late. Driveways close to Keswick Road see it as much as anywhere. The upshot: zero miles since makes it almost as good to spotting it at the petrol pump. Diesel and AdBlue stay apart: the AdBlue settles to the floor of your tank and remains put, however long the night. Put the keys in the house tonight — otherwise someone may drive it away at breakfast — and phone us. Egham Hythe or Thorpe Lea: whichever your drive sits, that's where it gets cleared. Even at night, the pumps stay quiet enough for a driveway. ## Set off with AdBlue in a diesel around Thorpe Lea? Lumpy running, smoke, lost power or a lit dashboard started a short way beyond the top-up. Maybe driving to Westminster, under 25 miles away, or just down Thirlmere Close. In short: the AdBlue has been pulled into your fuel system. Mileage sets how deep it goes: filter and lines first, then the high-pressure pump and each injector. More driving, more starts: further it travels. What to do: pull over where it is safe to do so then switch off. Leave at the next junction — not the services beyond — if you are on the M25, under a mile from Thorpe Lea. No test starts: clearing itself isn't something AdBlue will do. Phone, and say what distance your vehicle was driven. ## A hire or company car with AdBlue in the wrong tank? You have just had this car a week. The AdBlue filler is right next to the diesel filler, which you did not know, since your own car either has no AdBlue or keeps it somewhere else. Throughout Surrey, nobody is safe from it. What it means: the same as the scenarios above, depending on whether it's run, with one more stage. Work on the vehicle often needs the owner's approval under rental or fleet agreements. Settling it before the van turn up is quicker, and so phone the hire company or your fleet manager, and then us. Stuck near Roman Road Marker or at Egham until the firm answers, the vehicle stays switched off the whole time. ## AdBlue in the diesel tank? Not sure, around Thorpe Lea Now and then, "I think so" is the most anyone can truthfully say. A faint ammonia-like whiff lingers around your filler, the bottle seems too light, and which cap came off is hard to recall. A hurried stop by the gates of Manorcroft Primary School, or a visit to a friend in Stroude: both fit. The point: the engine is not hurt by some AdBlue spilled on the outside. The diesel tank with AdBlue inside is a different matter. You cannot tell which by turning the key, and doing so will pull in any AdBlue that is in your tank. What to do: treat it as if it went in. Do not fire it up. Phone with the details: we would sooner confirm a tank free of AdBlue than drain one once your engine has run. ## The common ground in each Thorpe Lea AdBlue drain The work begins identically, whichever your case. Anywhere your vehicle is — The Robin Hood's car park, a road by Egham Cricket Club, a drive, a filling station — the van gets there and asks for the fluid, the amount, and if your engine has turned over. Those replies decide the work, and you hear our quote by phone, before anyone sets off. Then your tank is emptied and your system purged thoroughly, which counts more with AdBlue than with petrol: AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it does not rinse out on its own. Then comes your filter — flushed, or swapped when necessary — then clean diesel, and a test of the car. Most unrun cars are a half-hour job from the moment our engineers get there. The final step is firing it up. Our test that it runs properly on clean diesel comes before our engineers leave. We do the whole job where the vehicle is, and permanent damage is very rare if it has been spotted soon. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Many policies cover misfuelling, and so check yours while the van travels. ## About Thorpe Lea Thorpe Lea is a suburban area in Surrey, situated on the riverside with an elevation of 17 metres, and is located near Egham Hythe and Egham.
