--- title: What Now? AdBlue in a Diesel Tank Guildford Park canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/guildford-park-surrey/ location: Guildford Park county: Surrey latitude: 51.237260 longitude: -0.588520 service: AdBlue in a Diesel Tank updated: 2026-10-01 --- # AdBlue in the Diesel Tank in Guildford Park, and What to Do Next What to do about AdBlue in a diesel tank depends on one thing more than any other: if your engine has been run since it went in. Over in Westborough or right around Guildford Park, an unstarted motor should stay unrun. Call 0333 366 0103 with the key and engine both off. In Guildford Park, that is typically emptied and flushed on the spot. When your engine has been run, stop somewhere safe first, then turn the vehicle off. The job is bigger, yet the first stage is the same. Compare your case to a situation from the list below, wherever in Surrey you are. ## Guildford Park forecourt: AdBlue in a diesel at the pump You are at the petrol pump, the nozzle or the bottle still in your hand, and you have just noticed the cap you opened was the wrong one. Possibly you are at the BP, maybe at the Shell, possibly somewhere else around Guildford Park. What it means: this is the best spot to find out. Still in your tank, and nothing pulled onwards: that is where the AdBlue is. What to do: don't get back in and fire it up to clear the petrol pump. Ring us from the forecourt once the vehicle is in a bay — the staff will lend a hand to roll it — and keep the receipt. Our equipment is explosion-proof and fine on a busy forecourt, and so a car that cannot be pushed away gets cleared right at the petrol pump. ## At home around Guildford Park with AdBlue in the diesel tank Several days had passed with the dash light on. Only at the recycling bin, the empty container in your hand, did you look back at the cap you'd opened at the driveway. Just off Madrid Road is not different from anywhere. Meaning? Provided the vehicle hasn't been driven since, it's second to the pump case. Diesel and AdBlue stay separate: the AdBlue settles to the floor of your tank and remains there, however long it waits. What to do: leave your keys inside the house so no one moves your car in the morning. Then ring. In Dennisville or here around Guildford Park, the draining is done on your driveway. The pumping kit runs quietly enough that it won't wake the neighbours at night. ## Set off with AdBlue in a diesel in Guildford Park? Rough running, smoke, falling power or a glowing dashboard started a short way after the fill. Old Palace Road, perhaps, or the route towards Westminster — a trip of under 50 miles. Meaning? The pump has sucked the AdBlue in. It has been through your filter and your lines and, the further you went, into the high-pressure pump and the fuel injectors. Every restart, like each mile, carries it on. Stop somewhere safe — that is the first job — then switch it off. Guildford Park sits under 10 miles from the M25; on it, pull off at the next junction instead of pushing on to the services. Don't restart the vehicle to see if it has cleared; it will not have. Ring us and say how far you drove. ## Hire, lease or company car with AdBlue in the wrong tank Seven days ago, it was unknown to you. Your own car either has no AdBlue or puts it elsewhere, and so no one told you the AdBlue cap was right next to the diesel. Wherever you happen to be around Surrey, every motorist could be caught. Put simply: one extra stage on top of the cases above, which turn on if it has run. The owner frequently has to sign off any work, under many rental and fleet contracts. Do this: rental firm or fleet manager to begin with, us second, since settling it beforehand saves time. Stuck near Grace Church Guildford or at Guildford until the firm replies, your car stays switched off throughout. ## AdBlue in your diesel tank? Not sure, in Guildford Park Occasionally the fair answer is "I think so". A slight ammonia whiff hangs near your filler, the bottle feels too light, and the cap you took off is a blur. Possibly it happened in a hurry at the school gates at Queen Eleanor's Church of England School, or on a friend's drive in Woodbridge Hill. Meaning? Spills around the filler never reach your engine at all. Inside the diesel tank, by contrast, AdBlue harms it. You can't tell which by turning the ignition, and doing so will pull in any AdBlue that is in the tank. What to do: treat it as if it got in. Don't crank it. Tell us what you saw on the phone. A clear tank checked is a better result than a run one emptied. ## Each AdBlue drain around Guildford Park shares these stages Each situation has the same start to the job. Filling station, driveway, The Astolat's car park or a street by The Cathedral Church of the Holy Spirit, Guildford — the van comes to your vehicle, and three answers follow: what fluid, which quantity, and whether it has run. Those replies determine the work, and you hear our price by phone, before anyone sets off. Then the tank is emptied and the fuel system flushed 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 doesn't rinse out on its own. Clean diesel is put in once the filter has been flushed or replaced, and the car is then tested. The majority of unrun cars are a half-hour job after the moment our technicians arrive. Last, our technicians start the engine. With fresh diesel in, it runs while our technicians make sure it's running correctly, and then we go. Permanent damage is very unusual when it is spotted early, and the whole job is done where the car is. For your insurer: an engineer's report and the VAT invoice. For you: payment on the day, no money upfront. Worth knowing: many insurers include misfuelling cover, and so a quick look at your documents while you wait is worthwhile. ## About Guildford Park itself Guildford Park is a suburban area in Surrey, situated on the riverside with an elevation of 51 metres.
