--- title: What Now? AdBlue in a Diesel Tank Bricket Wood canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/bricket-wood-hertfordshire/ location: Bricket Wood county: Hertfordshire latitude: 51.705720 longitude: -0.368770 service: AdBlue in a Diesel Tank updated: 2026-10-19 --- # AdBlue in the Diesel Tank in Bricket Wood, and What to Do Next One thing counts most once AdBlue is in a diesel tank, and that is whether the motor has been started afterwards. Not run so far? Then leave the car that way, wherever your car sits — Bricket Wood or Waterdale. Leave the motor and your ignition off and phone 0333 366 0103; it's normally a drain and a thorough flush, done where your car is in Bricket Wood. If it has run, stop as soon as it is safe and switch off. A bigger job, yes, yet the identical opening move. Match your case to a situation from the ones below, anywhere across Hertfordshire you are. ## AdBlue in a diesel on a Bricket Wood forecourt Imagine it: standing by the petrol pump, gripping the nozzle, you realise the cap you took off was not the correct one. Whether Harvest energy, Shell or somewhere else in Bricket Wood, the situation is the same. Meaning? Spotting it on the forecourt is as good as it gets. The AdBlue is inside the tank and nowhere else. Nothing has drawn it in. What to do: do not get back in and start the car to clear the petrol pump. A few things: a push into a bay with the attendants assisting, the bottle saved, and a ring to us from the forecourt. Stuck beside the petrol pump? Explosion-proof equipment keeps a busy forecourt sensible, and so it can be drained where it is. ## AdBlue in the diesel tank at home around Bricket Wood On the dash, a reminder had shown all week. A bottle from the garage, tipped in on the drive — and it was only at the bin that the cap caught a second look. Right off West Riding is no less likely from any other place. Put simply: if your vehicle has not moved since, it is almost as good as finding out at the pump. On the bottom of the tank sits exactly where AdBlue stays, since it will not blend with diesel — and a night going by makes nothing of the difference. Next: the keys in the house, so no one drives your car anywhere at breakfast. After that, phone. We drain the car on your drive, whether that is around Bricket Wood or out in Black Green. Late-night drains outside a house are no problem: the pumps are quiet. ## Bricket Wood: drove off with AdBlue in a diesel? 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. Mount Pleasant Lane, perhaps, or the way towards St Albans — a run of under 5 miles. The point: your system has drawn AdBlue through already. Through the fuel filter, through the lines, and — the more the distance — on into the injection pump and each injector. It goes deeper with every extra mile driven and each restart. Next: pick a sensible spot, stop, and turn your engine off. Exit by the next junction — not the services further along — if you are on the M1, under a mile from Bricket Wood. Don't restart it to see if it has cleared; it will not have. Roughly how far did it gone? Say so as you phone. ## A hire or company car with AdBlue in the wrong tank? You've had the car hardly a week. Your own vehicle either has no AdBlue or keeps it somewhere different, so nothing told you the AdBlue inlet sits just next to the diesel. Across Hertfordshire, no one is immune. Meaning? Whatever case above counts too — run or not — and one further step. The owner often has to sign off any work, under plenty of hire and fleet agreements. Settling it before we turn up is quicker, so ring the rental company or your fleet manager, and then us. Waiting for a reply at the car park at the nearest station, or near Saint Luke's Church, Bricket Wood? Leave your engine off meanwhile. ## Bricket Wood: unsure whether it was AdBlue in your diesel tank? "I think so" is sometimes the most honest answer there is. What cap came off, you can't say; meanwhile the bottle weighs lighter than expected, and a whiff of ammonia lingers by the filler. It might have been on a friend's driveway in Munden, or rushing outside Mount Pleasant Lane Primary School at the school run. In short: a spill near your filler does your engine no harm. In the diesel tank, however, AdBlue damages it. Any AdBlue in the tank would be sucked in by starting the vehicle, and the start would not settle which it is in any case. Take it that it got in, and never turn the key. Checking a tank that turns out free of AdBlue beats emptying one once it's been run — so phone then tell us what you saw. ## The common ground in each Bricket Wood AdBlue drain Every situation gets the same start to the job. Wherever your car stands — The Black Boy's car park, a street by St Stephen Parish Centre, a driveway, a forecourt — the van gets there and we ask for the liquid, the amount, plus if the motor has been run. Your price comes on the call, before a van leaves, and the replies set the work. A thorough flush comes after the drain. With petrol it is routine; with AdBlue it is essential, because deposits build up and certain metals corrode, and none of it washes out unaided. Next comes the fuel filter — flushed, or swapped where necessary — then clean diesel, and a test of your car. Most unstarted vehicles are a half-hour visit from the moment we turn up. Our engineers fire it up at the end. Our engineers confirm it runs smoothly on fresh diesel before we go. Our engineers do the whole job where your car is, and long-term damage is very rare when it has been caught soon. For your insurer: an engineer's report and the VAT invoice. For you: payment that day, nothing upfront. Plenty of insurance policies include misfuelling, and so check yours as we head over. ## About Bricket Wood itself Bricket Wood is a village in Hertfordshire, situated approximately 3.5 miles from St Albans and 17.2 miles from London.
