--- title: AdBlue in a Diesel Tank Southwick: What Now canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/southwick-west-sussex/ location: Southwick county: West Sussex latitude: 50.834440 longitude: -0.237850 service: AdBlue in a Diesel Tank updated: 2026-10-04 --- # What Now? AdBlue in the Diesel Tank in Southwick Everything turns on one fact: if the motor has started since the AdBlue went in — more than anything else. Wherever the vehicle is — Kingston by Sea, Southwick — don't run a motor that hasn't run yet. Leave the engine and your ignition off then ring 0333 366 0103; it's usually a drain and a thorough flush, done where your car is around Southwick. If it's run, stop as soon as it is safe and switch off. Stage one remains the same, even if the job is bigger. Match your case to one of the ones below, wherever across West Sussex you are. ## Southwick forecourt: AdBlue in a diesel at the pump Only now, nozzle still in your hand, it dawns on you that the cap you opened was the wrong one, right at the pump. Be it Tesco, Texaco or anywhere else in Southwick, the case is identical. Meaning? Spotting it here is as good as it gets. No pump has drawn it in, so the AdBlue sits only inside your tank. Clearing the petrol pump is no reason to start it — so do not get back in. Three things: a push into a bay with the attendants assisting, the bottle saved, and a call to us from where you stand. The equipment is explosion-proof and fine on a busy forecourt, so a car that can't be pushed away gets emptied where it is at the petrol pump. ## At home in Southwick with AdBlue in your diesel tank On the dash, a reminder had shown for days. You bought a bottle, poured it in on the driveway, and only when you put the empty bottle in the recycling did you look a second time at the cap. It happens on drives just off Southwick Square as often as anywhere. Meaning? As long as the vehicle hasn't moved since, it is second to the pump case. As it is unable to mix, AdBlue settles to the base inside the tank and stays. A night parked alters none of that. Keep the keys indoors overnight — or a person may drive it off first thing — then phone us. Your driveway is where it gets drained, be it around Southwick or Southern Cross. Night-time empties outside a house are no problem: the pumps are quiet. ## On the road in Southwick with AdBlue in a diesel You filled up, set off, and a mile or two later your engine began to run roughly, smoke, lose power or light up the dashboard. Maybe heading for Brighton and Hove, under 5 miles away, or just along The Green. The point: the system has pulled AdBlue in already. It has been through your filter and the fuel lines and, the further you went, into the high-pressure pump and your injectors. More driving, more restarts: deeper it travels. What to do: pull over where it is safe to do so then switch off. On the M23, under 25 miles from Southwick, that means the next junction, not the services further on. It will not have cleared, and so there is no point starting it again to find out. Tell us hear the mileage covered as you call. ## AdBlue in the wrong tank: hire, lease and company vehicles It's a motor you have had for a week. The AdBlue filler is right next to the diesel filler, which you did not know, since your own motor either has no AdBlue or keeps it somewhere else. Any driver, wherever across West Sussex, might do it. The upshot: just as above, split by whether it ran, but with an added stage. The owner often needs to approve any work, under many hire and company contracts. Next: phone the hire company or your fleet manager first, then us — settling it before we arrive is faster. Keep the vehicle off as the reply arrives, even if you're parked outside the nearest station or close to Southwick Library. ## Southwick: unsure whether it was AdBlue in the diesel tank? Now and then, "I think so" is all you can honestly say. A faint ammonia whiff hangs around the 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 Glebe Primary School, or on a friend's drive in Mile Oak. The point: the motor is not hurt by a little AdBlue spilled on the filler. If it is inside your diesel tank, though, it does. Any AdBlue in your tank would be sucked in by starting the car, and the start would not settle which it is in any case. Next: act as though it got in, then leave the engine off. Tell us what you saw on the phone. A clean tank checked counts as a happier outcome than an already-run one drained. ## Every AdBlue drain around Southwick shares these steps The work opens identically, whatever your situation. Anywhere your car is — The Cricketers's car park, a road beside St Michael and All Angels, a driveway, a forecourt — our van gets there and we ask about the fluid, the quantity, plus whether the engine has been run. Replies shape the job; the quote comes on the call whilst nobody has left yet. Then the tank is cleared and your system cleaned 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. Fresh diesel goes in once the fuel filter has been cleaned or replaced, and the car is then tested. If the engine hasn't run, most jobs take about half an hour once we're there. Our technicians start it last. We confirm it runs correctly on new diesel before we leave. When it is spotted early, the car very seldom has long-term damage, and the entire job happens where it is. Nothing is taken upfront, settlement happens on the day, and you receive what your insurer wants: an engineer report and a VAT invoice. Dig out your insurance while we're en route: misfuelling cover comes built into many policies. ## About Southwick, for a moment Southwick is a coastal town in West Sussex, situated near the city of Brighton and Hove, with a population of around 23208 people.
