--- title: What Now? AdBlue in a Diesel Tank Old Dock canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/old-dock-west-midlands/ location: Old Dock county: West Midlands latitude: 52.506920 longitude: -2.090930 service: AdBlue in a Diesel Tank updated: 2026-10-21 --- # AdBlue in the Diesel Tank in Old Dock, and What to Do Next All of that turns on a single fact: if the engine has been run after the AdBlue went in — more than anything else. If it hasn't, keep it that way, whether the vehicle is in Old Dock itself or out in Springs Mire. Normally this means draining and properly purging it right there in Old Dock — so leave your ignition and motor off and phone 0333 366 0103. Already started? Pull over when safe, then switch it off. The job is bigger, yet the first stage is the same. Anywhere around West Midlands it happened, one of the cases below matches yours. ## AdBlue in a diesel on a Old Dock forecourt Just at this point, bottle yet in hand, you realise that the cap you opened was the wrong one, there at the petrol pump. It might be the Texaco, or perhaps the another forecourt nearby, or a different station around Old Dock. What it means: this is the best location to find out. Just your tank holds AdBlue; not one component beyond it has drawn any in. Clearing the petrol pump is no reason to run it — and so do not get back in. Three things: a push into a bay with the attendants helping, the receipt kept, and a call to us from the forecourt. If it can't be shifted, it can be cleared at the pump: the equipment is explosion-proof and safe on a working forecourt. ## At home in Old Dock with AdBlue in the diesel tank On your dash, a reminder had been lit all week. Only by the recycling, the empty bottle in your hand, did you look back at the cap you'd used on the driveway. Right off Vauxhall Street is not different from anywhere. In short: if your car hasn't been driven since, it's almost equal to spotting it at the forecourt. At the bottom of that tank is exactly where AdBlue stays, because it will not mix with diesel — and a night passing makes no difference. Put the keys indoors tonight — or a person may take it off first thing — and phone us. In New Dock or right here in Old Dock, the drain happens at your drive. Late-night clears beside a house are fine: the pumps are low-noise. ## AdBlue in a diesel and already driving in Old Dock? Rough running, smoke, falling power or a glowing dashboard started a mile or two after the top-up. Perhaps it was on B4587, maybe on the way out towards Wolverhampton, under 10 miles away. The upshot: the system has pulled AdBlue through by now. It's been through the fuel filter and the fuel lines and, the further you went, into your high-pressure pump and the injectors. Each restart, like each mile, pushes it deeper. Next: pick a sensible place, stop, and turn your engine off. Services farther along can wait: from the M5, under 5 miles out of Old Dock, take the first junction. No trial starts: clearing itself is not something AdBlue will do. Ring us and say how far you went. ## A hire or company car with AdBlue in the wrong tank? You have only had the car for days. The AdBlue filler is right beside the diesel filler, which you didn't know, because your own motor either has no AdBlue or keeps it somewhere else. Throughout West Midlands, nobody is immune. Meaning? Whichever case above counts too — run or not — and one extra step. Many rental and company contracts require the owner's approval before repairs. What to do: call the hire firm or your fleet manager first, then us. That is faster settled before our technicians turn up than after. Waiting for an answer at the car park outside Tipton, or beside Queens Cross Christadelphian Hall? Keep the engine off throughout. ## Old Dock: unsure if it was AdBlue in the diesel tank? Occasionally the honest answer is "I think so". Which cap was taken off, you can't recall; but the bottle feels lighter than expected, and ammonia lingers by the filler. It might have been at a friend's drive in Eve Hill, or in a rush by Blowers Green Primary School at the school run. Meaning? Drips outside the inlet never touch your engine at all. A diesel tank with AdBlue in it is another matter. Any AdBlue in the tank would be pulled in by firing up your car, and the start would not settle which it is in any case. Do this: behave as though it got in, and never start the motor. Describe what you noticed on your phone. A clear tank checked counts as a happier result than a run one emptied. ## The common ground in every Old Dock AdBlue drain Whatever the situation, one start is used. Filling station, drive, The Lamp Tavern Batham's's car park or a street beside Destined To Reign Church — the van reaches the car, and three answers follow: what fluid, which amount, and whether it ran. Your price is given on the call, ahead of anyone setting off, and those replies shape the work. A thorough flush follows the drain. With petrol it's routine; with AdBlue it's crucial, since deposits build up and certain metals corrode, and none of it rinses out unaided. The filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and the car is tested. Never started? Then about half an hour on site covers most jobs. Our engineers start the car at the end. Our check that it runs smoothly on fresh diesel comes before our technicians leave. When it is caught soon, the car very rarely has permanent damage, and the entire job happens where it is. Paying is on the day, never in advance. For the insurer, you get a VAT invoice plus a written report from the engineer. Worth knowing: lots of insurers offer misfuelling cover, so a check of your documents while you wait pays. ## About Old Dock Old Dock is a suburban area in the West Midlands, situated on the riverside with nearby places including New Dock and Blowers Green.
