--- title: What Now? AdBlue in a Diesel Tank Upper Colwall canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/upper-colwall-herefordshire/ location: Upper Colwall county: Herefordshire latitude: 52.087910 longitude: -2.345410 service: AdBlue in a Diesel Tank updated: 2026-10-28 --- # Upper Colwall: AdBlue in the Diesel Tank? Find Your Situation Everything hinges on one fact: if the engine has started after the AdBlue went in — far more than anything else. If it hasn't, keep it that way, whether the vehicle is in Upper Colwall itself or out in Lower Wyche. Normally this means draining and thoroughly cleaning it on the spot in Upper Colwall — and so keep the key and motor off and ring 0333 366 0103. Already run? Stop when you safely can, then turn everything off. The job is bigger, yet the first step is the same. Wherever around Herefordshire it happened, one of the cases below fits yours. ## On a Upper Colwall forecourt with AdBlue in a diesel The cap you opened was the wrong one — and you only spot it as you're standing at the pump, bottle or the nozzle in your hand. Possibly you are at the Texaco, perhaps at the Gulf, possibly somewhere else around Upper Colwall. What it means: this is the best location to find out. Only your tank has AdBlue; not one part beyond it has drawn any in. Clearing the pump is no reason to start it — so don't get back in. Get the staff to lend a hand rolling it into a space, hold on to the bottle, then phone us right there. If it can't be moved, it can be drained at the petrol pump: the equipment is explosion-proof and fine on a working forecourt. ## Upper Colwall, at home: AdBlue in the diesel tank The warning light had been on for days. A bottle from the garage, tipped in at the drive — and it was only at the bin that the cap got a second look. Homes just off Walwyn Road are hit as often as everywhere else. In short: if the vehicle hasn't moved since, it is nearly equal to finding out at the pump. Diesel and AdBlue stay apart: the AdBlue drops to the floor of the tank and stays put, no matter how long the night. Next: the keys indoors, so nobody takes your car anywhere first thing. After that, phone. We drain it on your drive, whether that is around Upper Colwall or out in Upper Wyche. The equipment runs quietly enough that it won't wake the neighbours at night. ## AdBlue in a diesel and already driving around Upper Colwall? Lumpy running, smoke, lost power or a glowing dashboard started a short way beyond the fill. It might have been driving for Worcester, under 10 miles away, or just down Chase Road. Put simply: the AdBlue has been pulled through the system. The injection pump and each injector see it as well on a longer trip, once the fuel filter and pipework have it. It travels further with each extra mile driven and every restart. What to do: pull over where it's safe and switch off. On the M50, under 10 miles from Upper Colwall, that means the next exit, not the services further on. It will not have cleared, and so there is no sense starting it again to check. Phone us and say how far you travelled. ## AdBlue in the wrong tank of a hire, lease or company car You have had this car barely a week. Your own car either has no AdBlue or keeps it somewhere different, so no one told you the AdBlue cap was just beside the diesel. It can happen to anyone, anywhere across Herefordshire. Meaning? Whatever case above applies here — run or unrun — and one further stage. The owner often has to sign off the work, under many rental and fleet agreements. Sorting it before we arrives is faster, and so ring the hire company or your fleet manager, and then us. Stranded by Wyche Free Church or outside Colwall until someone replies, the car stays turned off the whole time. ## Upper Colwall: unsure whether it was AdBlue in your diesel tank? Sometimes the honest answer is "I think so". Too light, the bottle; a hint of ammonia round your filler; no clear memory of the cap. Sound familiar? It might have been on a friend's driveway in Colwall Green, or rushing outside Malvern Wyche CofE Primary School on the school run. Meaning? Spills outside the inlet never reach your engine at all. AdBlue inside the diesel tank does. If there is AdBlue in the tank, starting the car will pull it in, and it would not tell you which either. What to do: treat it as if it was put in. Don't fire it up. Ring and give what you saw: we would rather find a tank free of AdBlue than drain one once your motor has run. ## What every AdBlue drain around Upper Colwall has in common Each situation gets the same start to the job. Three things are asked once we reach your car — at a forecourt, a drive, a road by All Saints Malvern Wells & Wyche or the car park at Chase Inn: the liquid, the amount, and if the motor has run. Over the phone, before anything else, you hear our price, and those answers decide the work too. Emptying your tank comes next, followed by a full flush — more important after urea than with petrol, because crystals and corrosion will not clear by themselves, however long it sits. The fuel filter is flushed, or replaced where it needs to be; fresh diesel goes in; and the vehicle is tested. Most unstarted cars are a half-hour job from the moment we get there. The last step is firing it up. With new diesel in, it runs while we confirm it's running properly, and then we head off. Long-term damage is very uncommon if it is spotted early, and the whole job is done where the car is. Paying comes on the day, never upfront. For the insurer, there is a VAT invoice and a report from the engineer. Many insurance policies include misfuelling cover, and so it is worth checking yours while we are on the way. ## About Upper Colwall and where it is Upper Colwall is a suburban area in Herefordshire, situated near the Malvern Hills at an elevation of 189 metres.
