Find Your Situation What to do about AdBlue in a diesel tank comes down to one thing more than any other: if your engine has run since it got in. Over in Pallion or here in Low Southwick, an unstarted engine should remain that way. Switch nothing on, ring 0333 366 0103, then count on a proper flush after a drain, carried out right where the vehicle stands around Low Southwick. If it's run, stop as soon as it is safe and switch off. A larger job, yes, but the identical opening step. Find the scenario below that matches yours, wherever across Tyne and Wear it happened. ## On a Low Southwick forecourt with AdBlue in a diesel The cap you unscrewed was the wrong one — and you only notice it as you are standing at the petrol pump, bottle or nozzle in your hand. It might be the Sainsbury's, or the Asda, or a different forecourt around Low Southwick. In short: no better spot to be to spot it. Just your tank has AdBlue; no part past it has drawn any in. Freeing the petrol pump is no reason to run it — and so do not get back in. Ring us from the forecourt after the vehicle sits in a bay — the staff will help roll it — and save the bottle. Draining it there at the pump is fine if it cannot be shifted, because the equipment is explosion-proof. ## AdBlue in the diesel tank at home in Low Southwick The warning light had been on for days. A bottle from the garage, tipped in on the drive — and it was just by the recycling that the cap caught your eye. Just off Alexandra Avenue is not different from anywhere. Meaning? As long as the car has not moved since, it is second to the pump case. Diesel and AdBlue stay separate: the AdBlue settles to the base of the tank and remains put, however long the night. What to do: leave the keys inside the house so no one moves the car in the morning. Then ring. In Southwick or right here around Low Southwick, the draining is done at your drive. The pumps are quiet enough to use outside a house at night. ## Low Southwick: set off with AdBlue in a diesel? A mile or two after topping up, the motor began misbehaving: rough running, smoke, lost power, warnings on your dash. Maybe driving to Sunderland, under 3 miles away, or simply down Northern Way. Put simply: the AdBlue has been pulled through the system. Mileage decides how deep it goes: filter and lines first, then the high-pressure pump and each injector. Every restart, like each mile, carries it on. Stop somewhere safe — that is the next job — then switch everything off. Low Southwick lies under 5 miles from the A194(M); there, come off at the first junction rather than pressing on to the services. Don't restart it to see if it has cleared; it will not have. Phone us and say how far you went. ## AdBlue in the wrong tank: hire, lease and company motors Seven days back, it was unknown to you. The AdBlue filler is right next to the diesel one, which you didn't know, since your own car either has no AdBlue or keeps it somewhere else. Anywhere you are in Tyne and Wear, every motorist could slip up. Meaning? Whichever case above counts here — run or not — plus one extra step. Plenty of hire and company contracts want the owner to approve work on the vehicle. What to do: call the hire firm or your fleet manager first, then us. That's quicker settled before we get there than after. Hanging on for an answer at the car park at St Peters, or beside Sir William Mills? Leave the engine off throughout. ## Not sure it was AdBlue in your diesel tank, Low Southwick? Truthfully, the best answer may be that you think so. A faint ammonia whiff hangs around the filler, the bottle seems too light, and which cap came off is hard to recall. A rushed top-up by the gates of Southwick Community Primary School, or a visit to a friend in Marley Pots: both fit. In short: spillage round the filler leaves the engine no harm. AdBlue inside your diesel tank does. You can't tell which by turning the ignition, and doing so would pull in any AdBlue that is in the tank. Assume it went in, and don't turn your key. Ring us and explain what you saw; we would rather check a tank that turns out clean than drain one that has already been run. ## The common ground in each Low Southwick AdBlue drain No matter the case, one start is used. Three questions are asked when our engineers arrive — on a filling station, a drive, a street by Holy Trinity Southwick or the car park outside The Times Inn: the fluid, the amount, and if it has been started. Answers shape the work; the price comes on the call whilst no one has set off yet. Then that tank is drained and the fuel system rinsed thoroughly, which counts more with AdBlue than with petrol: AdBlue crystallises and is corrosive to some of the metals in a fuel system, and so it doesn't rinse out on its own. Next comes the filter — cleaned, or swapped when needed — then clean diesel, and a test of your vehicle. Where the motor hasn't been started, allow about half an hour once we arrive, for most jobs. Last, our technicians start the car. Before we head off, it's tested to make sure it runs smoothly on new diesel. Our engineers do the entire job where the vehicle is, and long-term damage is very rare if it has been caught early. Paying comes that day, never in advance. For your insurer, there is a VAT invoice plus a written report from the engineer. Dig out your insurance before we're en route: misfuelling cover comes included in plenty of policies. ## About Low Southwick and where it is Low Southwick is a suburban area located on the coast of Tyne and Wear, near the city of Sunderland.
