--- title: What Now? AdBlue in a Diesel Tank Walton on the Hill canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/walton-on-the-hill-surrey/ location: Walton on the Hill county: Surrey latitude: 51.282680 longitude: -0.247260 service: AdBlue in a Diesel Tank updated: 2026-10-18 --- # AdBlue in the Diesel Tank in Walton on the Hill: What Now? Has the motor run since the AdBlue was put in? This single question settles almost everything else from here. Anywhere your car stands — Hogden Bottom, Walton on the Hill — don't start a motor that has not run yet. Usually that is emptying and properly purging it on the spot in Walton on the Hill — and so keep the ignition and engine off then phone 0333 366 0103. Pull over the moment it is safe then switch off, if it has already run. The job is bigger, yet the first stage is the same. Find the situation below that matches yours, wherever across Surrey it happened. ## AdBlue in a diesel on a Walton on the Hill forecourt Picture it: standing by the pump, gripping the bottle, you realise the filler you took off was not the right one. Anywhere in Walton on the Hill, then — Texaco, BP, or somewhere else close by. What it means: this is the ideal location to find out. Nothing has pulled it through, so the AdBlue sits just inside the tank. Next: resist the temptation to start it just to move away from the pump. Have the attendants to lend a hand pushing it to a bay, save the receipt, then phone us right there. Draining it right at the petrol pump is possible when it can't be shifted, because the equipment is explosion-proof. ## AdBlue in your diesel tank at home in Walton on the Hill On the dash, a warning had been lit all week. You bought a bottle, poured it in on the driveway, and only when you put the empty bottle in the recycling did you look again at the cap. Houses just off Ebbisham Lane are caught out as often as everywhere else. Meaning? Provided the car hasn't moved since, it is second to the forecourt case. At the floor of your tank is exactly where AdBlue stays, because it will not blend with diesel — and a night passing makes nothing of the difference. Your move: keys in the house, so nobody drives the vehicle anywhere first thing. Then, phone. Your drive is where it gets emptied, whether in Walton on the Hill or Tadworth. Night-time clears beside a house are no problem: the pumps are quiet. ## AdBlue in a diesel and already driving around Walton on the Hill? Rough running, smoke, falling power or a glowing dashboard arrived a short way after the top-up. Walton Street, perhaps, or the route towards Westminster — a run of under 25 miles. In short: the AdBlue has been sucked through the fuel system. Through your filter, along the pipework, and — the more the mileage — deeper into the high-pressure pump and every injector. It goes further with each extra mile covered and each restart. Next: find a sensible place, pull in, then switch your motor off. On the M25, under a mile from Walton on the Hill, that means the next exit, not the services further on. Restarting it to check gets nothing — AdBlue never clears on its own. Ring us and say how far you went. ## Hire, lease or company car with AdBlue in the wrong tank Seven days back, it was unknown to you. The AdBlue filler is right next to the diesel one, which you didn't know, because your own car either has no AdBlue or keeps it somewhere else. Across Surrey, nobody is safe from it. The upshot: exactly as above, split by whether it ran, only with one added stage. Many hire and company agreements want the owner to approve work on the vehicle. What to do: ring the hire firm or your fleet manager first, then us. That's faster settled before we turn up than after. Leave the car off as the reply arrives, whether you're waiting at Tadworth or close to St Peter. ## AdBlue in your diesel tank? Not sure, around Walton on the Hill Honestly, the only answer may be that you think it did. The bottle is lighter than it should be, there's a faint smell of ammonia round the filler, and you can't remember which cap you took off. A hurried stop by the gates of Walton-on-the-Hill Primary School, or a call to a friend in Mogador: both fits. What it means: a little spilled around your filler does no damage to the engine. A diesel tank with AdBlue in it is a different story. Any AdBlue in that tank will be drawn in by starting the car, and the start would not settle which it is in any case. Do this: act as if it got in, and never start your engine. Phone with what you saw: we'd sooner find a tank free of AdBlue than empty one once the engine has run. ## The common ground in every Walton on the Hill AdBlue drain The work opens the same way, whichever your situation. Our engineers come to your car, whether it's at a forecourt, a drive, the car park outside The Fox & Hounds or a side street near Church of the Good Shepherd, and ask three things: what got in, about how much, and if the motor has been run. Replies shape the work; the price follows on the call whilst nobody has left yet. Then that tank is emptied and your system purged thoroughly, which matters more with AdBlue than with petrol: AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it doesn't rinse out on its own. Then comes the filter — cleaned, or replaced when necessary — then fresh diesel, and a test of your vehicle. Where the engine has not been started, expect about half an hour on site, for most jobs. Firing it up comes at the end. With fresh diesel in, it runs while our engineers confirm it's running properly, and then we go. Our engineers do the whole job where your car is, and lasting damage is very uncommon if it has been caught early. Nothing is paid upfront, settlement is made on the day, and you get what your insurer asks for: an engineer report and a VAT invoice. Plenty of insurance policies include misfuelling cover, and so it's worth checking yours whilst we're on the way. ## About Walton on the Hill and where it is Walton on the Hill is a village in Surrey, situated on a hilltop at an elevation of 181 metres, with views over the surrounding countryside.
