--- title: AdBlue in a Diesel Tank Hawks Hill? Next Steps canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/hawks-hill-surrey/ location: Hawks Hill county: Surrey latitude: 51.286930 longitude: -0.345130 service: AdBlue in a Diesel Tank updated: 2026-10-06 --- # What Now? AdBlue in the Diesel Tank in Hawks Hill Has your engine run since the AdBlue went in? That single question settles almost everything else from here. Not started yet? Then leave the vehicle that way, whether the vehicle sits — Hawks Hill or Givons Grove. Usually that means emptying and thoroughly cleaning it right there in Hawks Hill — so keep the key and motor off and call 0333 366 0103. When the engine has been run, stop safely straight away, then turn it off. It is a larger job, yet stage one does not change. Find the scenario below that matches yours, wherever across Surrey it happened. ## On a Hawks Hill forecourt with AdBlue in a diesel The cap you unscrewed was the wrong one — and you only spot it while you are standing at the pump, bottle or the nozzle in hand. Anywhere around Hawks Hill, then — Esso, BP, or somewhere else nearby. The point: of all places to notice, this is the best. Only the tank has AdBlue; no part past it has taken it in. Do this: keep out of the car, even if the pump needs freeing. Get the staff to help rolling it to a bay, hold on to the bottle, then phone us from there. If it cannot be moved, it can be drained at the petrol pump: the equipment is explosion-proof and safe on a working forecourt. ## AdBlue in your diesel tank on a Hawks Hill drive? On the dash, a warning had shown all week. Bought a container, poured it in at home, binned the empty — and at that point checked the cap a second time, after the fact. Just off Mount Close is no different from anywhere. Meaning? As long as your car hasn't moved since, it's second to the forecourt case. AdBlue doesn't mix with diesel; it sinks to the bottom of your tank and waits there. Overnight does not change that. Next: prevent an early drive by putting the keys in the house, then phone us. Fetcham or Hawks Hill: whichever your drive is, that is where it gets drained. Even at night, the pumps are quiet enough for a residential street. ## On the road around Hawks Hill with AdBlue in a diesel Lumpy running, smoke, lost power or a glowing dashboard started a mile or two after the fill. Guildford Road, perhaps, or the route to Westminster — a run of under 25 miles. The upshot: your system has pulled AdBlue through already. It's been through your filter and your lines and, the further you went, into the high-pressure fuel pump and your injectors. More driving, more starts: deeper it travels. What to do: pull over where it's safe to do so then switch off. Leave at the first junction — not the services further along — if you are on the M25, under 3 miles from Hawks Hill. No test starts: clearing isn't something AdBlue does. Call, saying what distance your vehicle was driven. ## A hire or company car with AdBlue in the wrong tank? You've had the vehicle hardly a week. Your own vehicle either has no AdBlue or puts it somewhere different, and so no one told you the AdBlue cap was just next to your diesel. Anyone, anywhere in Surrey, could do it. Put simply: one extra step on top of the cases above, which depend on if it's run. The owner frequently has to sign off any work, under many hire and company agreements. Next: ring the rental company or the fleet manager first, then us — sorting it before we arrive is quicker. If you're stranded in the car park at Leatherhead, or by North Downs, whilst you wait for an answer, leave your car off. ## AdBlue in the diesel tank? Not sure, around Hawks Hill Now and then, "I think so" is the most you can truthfully say. Too light, the bottle; a trace of ammonia near your filler; a hazy memory of which cap. Look familiar? The gates of Fetcham Village Infant School in a hurry, perhaps, or someone's drive over in Great Bookham. What it means: a little spilled round the filler does no harm to your engine. If it's inside your diesel tank, though, that changes. Any AdBlue in the tank will be drawn in by firing up the vehicle, and the start would not settle which it is in any case. Your move: behave as if it got in, and never start your engine. Call us and describe what you saw; we'd rather check a tank that turns out free of AdBlue than drain one that has already been run. ## Hawks Hill: what every AdBlue drain has in common Each situation has the same start to the work. Wherever the car stands — The Bell's car park, a street by St. Marys Church Fetcham, a drive, a filling station — our van arrives and we ask for the fluid, the quantity, and whether your motor has turned over. Those replies settle the work, and you hear the price by phone, before anybody sets off. Then the tank is emptied and the system cleaned 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 does not rinse out on its own. Finally are the filter, cleaned or renewed if necessary; fresh diesel; and a check of your car. Not started? Then roughly half an hour once we are there covers most jobs. Last, we fire it up. Our check that it runs correctly on new diesel comes before our technicians leave. When it's spotted quickly, the vehicle very rarely has permanent damage, and the entire job takes place where it is. For your insurer: the engineer's report and the VAT invoice. For you: payment on the day, nothing in advance. Many insurance policies include misfuelling cover, so it's worth checking yours while we are on the way. ## About Hawks Hill, for a moment Hawks Hill is a locality in Surrey, situated inland at an elevation of 78 metres, and is located approximately 17.9 miles from London.
