--- title: What Now? AdBlue in a Diesel Tank Custom House canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/custom-house-greater-london/ location: Custom House county: Greater London latitude: 51.514610 longitude: 0.042090 service: AdBlue in a Diesel Tank updated: 2026-10-13 --- # AdBlue in the Diesel Tank in Custom House, and What to Do Next One fact matters above all when AdBlue is in a diesel tank, and it is whether your motor has been started afterwards. Not run yet? Then leave the car like that, whether the vehicle sits — Custom House or Cyprus. Leave the engine and your ignition off then call 0333 366 0103; it is normally a drain and a thorough flush, done where your car is in Custom House. Pull over the minute it is safe then switch off, if it has been run. Step one stays unchanged, even though the work grows. Wherever across Greater London it happened, one of the cases below matches yours. ## Custom House forecourt: AdBlue in a diesel at the pump Picture it: standing by the pump, holding the nozzle, you spot the filler you opened was not the correct one. Somewhere in Custom House, then — Asda, BP, or anywhere else close by. What it means: this is the ideal spot to find out. Still in the tank, and nothing pulled through: that's where the AdBlue sits. Next: avoid the urge to start it only to free up the petrol pump. Ask the staff to help you push the vehicle into a parking bay, keep the till receipt or the bottle, then ring us from the forecourt. The equipment is explosion-proof and fine on a busy forecourt, and so a vehicle that can't be pushed away is emptied where it is at the pump. ## Custom House, at home: AdBlue in your diesel tank For days the dashboard had been nagging you. You bought a bottle, poured it in on the drive, and only when you put the empty bottle in the recycling did you look a second time at the cap. Houses just off Fulmer Road get hit as much as everywhere else. Put simply: if your car hasn't been driven since, it's nearly as good as spotting it at the pump. Diesel and AdBlue keep apart: the AdBlue settles to the base of the tank and stays there, however long it waits. Next: prevent an early drive by putting your keys indoors, then phone us. Beckton or Custom House: whichever your drive is, that's where it gets emptied. Our equipment runs quietly enough that it won't wake the neighbours at night. ## Set off with AdBlue in a diesel around Custom House? A mile or two beyond filling up, your motor began misbehaving: roughness, smoke, less power, lights on the dash. Perhaps it was on Alestan Beck Road, possibly on the way out towards London, under 10 miles away. In short: the AdBlue has been sucked through the fuel system. It's been through the fuel filter and your lines and, the further you went, into the high-pressure pump and the fuel injectors. More miles, more restarts: further it travels. Stop somewhere safe — that's the next job — then turn everything off. Custom House sits under 5 miles from the M11; on it, pull off at the next junction instead of pushing on to the services. No test starts: clearing itself is not something AdBlue will do. Phone us and say how far you drove. ## A hire or company car with AdBlue in the wrong tank? It is a vehicle you have had for a week. The AdBlue filler is right alongside the diesel one, which you did not know, since your own car either has no AdBlue or keeps it somewhere else. Throughout Greater London, nobody is immune. What it means: the same as the scenarios above, depending on whether it's run, with one more stage. Plenty of hire and company contracts want the owner to approve work on your car. Settling it before the van turn up is quicker, so ring the hire company or your fleet manager, and then us. Stranded by Lighthouse Christian Fellowship or at the nearest station until the firm answers, the vehicle remains turned off throughout. ## Not sure it was AdBlue in the diesel tank, Custom House? At times the honest answer is "I think so". A faint ammonia smell hangs around your filler, the bottle seems too light, and which cap came off is a blur. The gates of Ellen Wilkinson Primary School in a hurry, say, or someone's driveway over in Docklands. Meaning? Spills around the filler don't touch your engine at all. The diesel tank with AdBlue in it is another matter. If there is AdBlue in the tank, starting the car would draw it in, and it would not tell you which either. What to do: treat it as if it went in. Do not crank it. Checking a tank that proves free of AdBlue is better than emptying one after it has been run — so phone then tell us what you noticed. ## Every AdBlue drain in Custom House shares these steps Each situation has the same start to the job. Forecourt, drive, Fox@Connaught's car park or a street by Ascension Church Centre — the van reaches the vehicle, and three questions follow: what fluid, what amount, and whether it has run. Your price comes over the phone, ahead of anyone setting off, and the replies shape the work. A thorough flush follows the drain. With petrol it is routine; with AdBlue it's essential, since deposits form and certain metals corrode, and neither washes out unaided. Clean diesel is put in after your filter has been flushed or changed, and your car is then tested. If the engine hasn't run, most jobs take about half an hour once we're there. Our technicians fire it up last. With clean diesel in, it runs while our technicians confirm it is running correctly, and then we head off. Our engineers do the entire job where the car is, and lasting damage is very rare if it has been noticed soon. Nothing is paid upfront, payment is made on the day, and you get what the insurer asks for: an engineer report plus a VAT invoice. Check your insurance while we're en route: misfuelling cover comes built into plenty of policies. ## About Custom House itself Custom House is a suburban area in the London Borough of Newham, situated approximately 5.8 miles east of central London.
