--- title: AdBlue in a Diesel Tank Ottershaw? Next Steps canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/ottershaw-surrey/ location: Ottershaw county: Surrey latitude: 51.365310 longitude: -0.532260 service: AdBlue in a Diesel Tank updated: 2026-10-21 --- # Ottershaw: 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 the engine has run since it got in. Out in Fan Grove or right in Ottershaw, an unstarted engine should stay that way. Leave your motor and the ignition off and ring 0333 366 0103; it is generally a drain and a thorough flush, done where the car is in Ottershaw. When the motor has been run, stop safely straight away, then switch it off. Step one stays unchanged, even if the job is bigger. Anywhere around Surrey it happened, one of the cases below matches yours. ## Ottershaw forecourt: AdBlue in a diesel at the pump Just now, bottle yet in your hand, you realise that the cap you took off was the wrong one, right at the pump. Perhaps you are at the Shell, possibly at the Tesco, maybe somewhere else around Ottershaw. What it means: this is the ideal spot to find out. Just the tank holds AdBlue; not one part beyond it has drawn it in. Your move: stay out of the driver's seat, however much the queue needs clearing. Get the staff to lend a hand rolling it to a bay, save the receipt, then phone us from there. Our equipment is explosion-proof and safe on a busy forecourt, so a car that cannot be pushed clear is drained where it is at the pump. ## AdBlue in your diesel tank at home in Ottershaw For days the dash had been warning you. 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. Drives near Guildford Road see it as much as any other street. Meaning? As long as your car hasn't been driven since, it is close to the forecourt case. As it is unable to mix, AdBlue settles low inside the tank and waits. One night parked alters nothing. What to do: leave your keys inside the house so no one moves your car in the morning. Then call. In Rowhill or here in Ottershaw, the drain is done on your driveway. Our equipment works quiet enough not to disturb the street at night. ## On the road in Ottershaw with AdBlue in a diesel A mile or two after filling up, your engine started playing up: rough running, smoke, lost power, lights on your dash. Maybe it was on Chobham Road, possibly on the way out towards Westminster, under 25 miles away. What it means: the fuel system has sucked the AdBlue in. Distance decides how deep it gets: filter and lines to begin with, then the high-pressure pump and every injector. Every restart, like every mile, pushes it on. Your move: stop somewhere sensible, then switch the engine off. On the M25, under 3 miles from Ottershaw, that means the next junction, not the services further on. Starting it again to check gets nothing — AdBlue never clears on its own. Phone, and say what distance the car was driven. ## A hire or company car with AdBlue in the wrong tank? You've only driven this car a week. The AdBlue filler sits right alongside the diesel one, which you didn't know, because your own motor either has no AdBlue or keeps it somewhere else. Across Surrey, nobody is safe from it. Meaning? Whichever applies above counts here — run or unrun — and one extra stage. Plenty of hire and company agreements want the owner to approve work on the car. Do this: hire firm or your fleet manager first, us next, since sorting it early cuts time. Waiting for an answer in the car park at Chertsey, or near Ottershaw Village Hall? Leave the engine off meanwhile. ## Not sure it was AdBlue in your diesel tank, Ottershaw? Honestly, the only answer may be that you think so. What cap was taken off, you can't recall; but the bottle feels lighter than expected, and a whiff of ammonia hangs by your filler. The gates of Ottershaw Christ Church Church of England Junior School in a rush, perhaps, or a friend's driveway over in Lyne. The upshot: your engine is not hurt by some AdBlue spilled around the outside. If it is inside the diesel tank, though, that changes. Firing up your car won't tell you which, and if there is AdBlue in the tank it will draw it in. What to do: treat it as if it got in. Do not start the vehicle. Tell us what you saw on the phone. A clean tank checked counts as a happier outcome than an already-run one drained. ## What every AdBlue drain around Ottershaw has in common No matter the situation, a single opening applies. Anywhere your vehicle is — The Castle's car park, a road by Christ Church, a drive, a forecourt — our van arrives and asks about the liquid, the quantity, and if your motor has been run. Replies set the job; the price follows on the call whilst no one has set off yet. Then the tank is drained and the system flushed 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. The fuel filter is flushed, or replaced where it needs to be; clean diesel goes in; and the vehicle is tested. The majority of unstarted cars are a half-hour visit from the moment our technicians turn up. Last, our engineers start it. Our test that it runs smoothly on clean diesel comes before our engineers head off. We do the entire job where the vehicle is, and lasting damage is very unusual if it has been spotted early. Nothing is paid upfront, payment is made on the day, and you get what your insurer asks for: an engineer report and a VAT invoice. Check your insurance while we're en route: misfuelling cover is included in many policies. ## About Ottershaw Ottershaw is a village in Surrey, situated inland at an elevation of 39 metres, approximately 20 miles from London.
