--- title: AdBlue in a Diesel Tank Foster Street: What Now canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/foster-street-essex/ location: Foster Street county: Essex latitude: 51.757870 longitude: 0.149870 service: AdBlue in a Diesel Tank updated: 2026-10-17 --- # AdBlue in the Diesel Tank in Foster Street: What Now? What to do about AdBlue in a diesel tank comes down to one thing more than any other: whether the motor has been run since it went in. Anywhere the vehicle stands — Harlow Common, Foster Street — never start an engine that hasn't run yet. Leave your engine and your ignition off then phone 0333 366 0103; it's usually a drain and a thorough flush, done where the vehicle is around Foster Street. Where the engine has been run, stop somewhere safe first, then switch the car off. It is a larger job, though step one does not change. Anywhere around Essex it took place, one of the cases below fits yours. ## On a Foster Street forecourt with AdBlue in a diesel The cap you opened was the wrong one — and you only notice it as you are standing at the petrol pump, bottle or nozzle in hand. Possibly you're at the BP, perhaps at the Shell, maybe somewhere else in Foster Street. Meaning? Spotting it here is the best it gets. No pump has drawn it in, so the AdBlue sits only in your tank. Do this: keep out of the car, even if the queue wants freeing. Phone us from the forecourt once your vehicle sits in a space — the staff will lend a hand to roll it — then keep the receipt. Can't move it beside the pump? Explosion-proof kit makes a busy forecourt safe, and so it can be drained in place. ## AdBlue in your diesel tank on a Foster Street drive? Days had gone by with the dash light on. Bought a bottle, poured it in outside the house, recycled the empty — and at that point checked the cap a second time, after the fact. Driveways close to Hastingwood Park see it as much as any other street. Put simply: if the vehicle has not been driven since, it is almost equal to spotting it at the pump. AdBlue does not mix with diesel; it sinks to the bottom of that tank and waits there. Overnight does not change that. Keep the keys in the house tonight — or someone may drive it away first thing — then call us. Church Langley or Foster Street: whichever your driveway sits, that is where it gets drained. Late-night clears outside a house are fine: the pumps are quiet. ## On the road in Foster Street with AdBlue in a diesel Rough running, smoke, falling power or a glowing dashboard started a short way beyond the fill. Anywhere on Mill Street or else heading towards Chelmsford — under 15 miles away. The point: your system has drawn AdBlue in by now. The high-pressure pump and each injector get it as well on a bigger trip, once the fuel filter and pipework have had it. More driving, more restarts: deeper it goes. Next: find a safe spot, stop, then switch the engine off. Foster Street sits under a mile from the M11; on it, come off at the next junction instead of pushing on for the services. No trial restarts: clearing is not something AdBlue will do. Call, and say what distance the car was driven. ## A hire or company car with AdBlue in the wrong tank? A week ago, the car was new to you. Your own motor either has no AdBlue or puts it elsewhere, so no one told you the AdBlue inlet sits right beside the diesel. Anyone, anywhere across Essex, could do the same. What it means: the same as the situations above, depending on whether it has run, with one more step. Work on your vehicle frequently requires the owner's go-ahead under hire or fleet agreements. Do this: rental firm or your fleet manager first, us second, since settling it beforehand cuts time. Leave it switched off while the answer comes, even if you are parked outside Harlow Mill or close to Potter Street Community Centre. ## Not sure it was AdBlue in your diesel tank, Foster Street? At times, "I think so" is the most you can honestly say. Lighter, the bottle; a trace of ammonia round the filler; no clear memory of which cap. Sound familiar? A hurried stop by the gates of Henry Moore Primary School, or a visit to a friend in Threshers Bush: either fit. What it means: a little spilled around the filler does no damage to the engine. In your diesel tank, however, AdBlue harms it. Starting your car cannot tell you which, and if there is AdBlue in the tank it would draw it in. Your move: behave as though it did, and don't start the engine. Describe what you noticed on the phone. A clear tank looked at is a happier outcome than a run one emptied. ## What every AdBlue drain around Foster Street has in common Each situation has the same start to the job. Forecourt, drive, The Horns And Horseshoes's car park or a street beside St Mary Magdalene, Harlow — the van comes to your car, and three questions come next: which fluid, what quantity, and whether it has run. Those answers settle the work, and you get our quote on the phone, before anyone heads out. AdBlue crystallises and eats at certain metals in fuel systems, so it does not rinse out unaided; that is why the flush, after this drain, matters much more here than with petrol. Finally come your filter, cleaned or renewed as needed; fresh diesel; and a test of your vehicle. If your engine hasn't run, the majority of jobs take about half an hour once we are there. We start it at the end. Our test that it runs correctly on clean diesel comes before we leave. Permanent damage is very rare if it's noticed soon, and the entire job is done where the car is. Payment is that day, never in advance. For the insurer, there is a VAT invoice plus a written report from the engineer. Check your insurance while we're en route: misfuelling cover is built into plenty of policies. ## About Foster Street, briefly Foster Street is a small village in Essex, situated inland at an elevation of around 100 metres, and is located approximately 21 miles from London.
