--- title: AdBlue in a Diesel Tank Sidcup? Next Steps canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/sidcup-greater-london/ location: Sidcup county: Greater London latitude: 51.435570 longitude: 0.101990 service: AdBlue in a Diesel Tank updated: 2026-10-21 --- # AdBlue in the Diesel Tank in Sidcup: What Now? What to do about AdBlue in a diesel tank depends on one thing more than any other: whether the motor has run since it got in. Over in Blackfen or right in Sidcup, an unstarted motor must remain unrun. Leave your motor and your ignition off then call 0333 366 0103; it's generally a drain and a thorough flush, done where the vehicle is in Sidcup. Already started? Pull over when you safely can, then switch everything off. A bigger job, then, yet the identical first step. Find the situation below that matches yours, wherever across Greater London it happened. ## At the petrol pump around Sidcup: AdBlue in a diesel Picture it: standing by the petrol pump, gripping the nozzle, you spot the filler you took off was not the correct one. It could be the Harvest Energy, or the another forecourt nearby, or another station in Sidcup. Meaning? Spotting it on the forecourt is as good as it gets. No pump has drawn it through, so the AdBlue stays only in the tank. Your move: stay out of the car, even if the pump wants freeing. Phone us from the forecourt after your vehicle is in a space — the attendants will help roll it — and keep the receipt. Can't move it by the pump? Our explosion-proof kit keeps a live forecourt sensible, so it can be drained in place. ## AdBlue in the diesel tank at home in Sidcup The warning light had been on for days. Bought a container, poured it in outside the house, binned the empty — and at that point looked at the cap a second time, too late. It happens on driveways just off Hurst Road as regularly as anywhere. Meaning? Provided your vehicle hasn't been driven since, it is close to the pump case. As it is unable to blend, AdBlue drops to the base in the tank and waits. One night standing alters nothing. What to do: leave the keys inside the house so no one moves the car in the morning. Then ring. We drain it on your drive, whether that is around Sidcup or out in Lamorbey. Our pumping kit works quietly enough that it won't wake the neighbours at night. ## Drove off with AdBlue in a diesel around Sidcup? You filled up, set off, and a mile or two later the motor began to run roughly, smoke, lose power or light up the dashboard. Maybe driving for London, under 15 miles away, or just down Halfway Street. The point: the system has pulled AdBlue through already. Mileage decides how far it gets: filter and pipework first, then the high-pressure pump and each injector. More driving, more restarts: deeper it travels. Next: find a safe place, pull in, then turn your engine off. On the M20, under 5 miles from Sidcup, that means the next exit, not the services further on. No trial starts: clearing itself is not something AdBlue does. Let us know the mileage covered when you call. ## A hire or company car with AdBlue in the wrong tank? A week ago, it was new to you. The AdBlue filler is right next to the diesel filler, which you didn't know, because your own vehicle either has no AdBlue or keeps it somewhere else. Anywhere you happen to be in Greater London, every driver could slip up. The upshot: just as above, divided by if it ran, only with an added step. Many rental and company contracts require the owner's approval before work. What to do: call the hire firm or your fleet manager first, then us. That is quicker settled before we arrive than after. Stranded by Holy Trinity Church Hall or at the nearest station till the firm replies, your car stays turned off the whole time. ## Not sure it was AdBlue in your diesel tank, Sidcup? Now and then, "I think so" is the most anyone can truthfully say. Too light, the bottle; a hint of ammonia round your filler; a hazy recollection of which cap. Sound familiar? The gates of Holy Trinity Lamorbey Church of England School in a rush, say, or someone's drive out in Blendon. What it means: a little spilled about the filler does no damage to the motor. Once it's inside the diesel tank, though, that changes. Any AdBlue in that tank will be sucked in by turning on the vehicle, and the start wouldn't settle which it is in any case. What to do: treat it as if it went in. Don't start it. Call us and explain what you saw; we'd rather check a tank that turns out clean than drain one that has already been run. ## Sidcup: what every AdBlue drain has in common Whatever the case, a single opening is used. Wherever the vehicle is — The Hackney Carriage's car park, a road beside Holy Trinity Church, a drive, a filling station — our van arrives and we ask about the liquid, the quantity, and if your motor has been run. Your price comes on the call, before a van leaves, and the replies shape the work. Then the tank is emptied and the system rinsed 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. Fresh diesel goes in once the filter has been cleaned or replaced, and the car is finally checked. If the motor has not run, most jobs take about half an hour once we're there. The final step is firing it up. Before our technicians head off, it's tested to be sure it runs properly on fresh diesel. The entire job is done where the vehicle is, and when it is caught quickly, long-term damage is very uncommon. Payment is that day, never in advance. For your insurer, you get a VAT invoice and a written report from the engineer. It is worth remembering: many insurers offer misfuelling cover, and so a quick look at your policy as we travel is worthwhile. ## About Sidcup Sidcup is a locality in southeastern Greater London, situated near the River Thames at an elevation of around 34 metres.
