--- title: AdBlue in a Diesel Tank Marsh Barton? Next Steps canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/marsh-barton-devon/ location: Marsh Barton county: Devon latitude: 50.706660 longitude: -3.529060 service: AdBlue in a Diesel Tank updated: 2026-10-26 --- # What Now? AdBlue in the Diesel Tank in Marsh Barton What to do about AdBlue in a diesel tank depends on one thing more than any other: whether your engine has been run since it got in. Over in St Leonards or right in Marsh Barton, an unrun engine should stay that way. Switch nothing on, call 0333 366 0103, then expect a proper flush plus a drain, done just where your vehicle stands in Marsh Barton. Stop the minute you safely can and turn off, if it has already run. The job is bigger, yet the first step is the same. Find the scenario below that matches yours, wherever in Devon it happened. ## Marsh Barton forecourt: AdBlue in a diesel at the pump Imagine it: standing by the petrol pump, gripping the nozzle, you realise the cap you took off wasn't the correct one. It could be the Valero, or the Esso, or another station in Marsh Barton. The upshot: of every spot to find out, the forecourt is the best. Still inside the tank, and nothing drawn through: that is where the AdBlue is. Next: avoid the urge to fire it up just to move away from the petrol pump. Ask the attendants to help you roll the car into a parking spot, keep the till receipt or the bottle, then phone us from the forecourt. If it can't be shifted, it can be emptied at the petrol pump: the equipment is explosion-proof and fine on a busy forecourt. ## AdBlue in your diesel tank at home around Marsh Barton Days had gone by with the warning light on. Bought a container, tipped it in at home, binned the empty — and only then looked at the cap a second time, after the fact. Driveways near Marsh Green Road East see it as much as anywhere. Meaning? Provided the vehicle hasn't been driven since, it is close to the forecourt case. Diesel and AdBlue stay apart: the AdBlue drops to the floor of that tank and stays put, no matter how long it waits. Put the keys in the house tonight — otherwise someone may take it off at breakfast — and call us. Out in Alphington or here in Marsh Barton, the drain happens at your drive. The equipment works quiet enough that it won't wake the street at night. ## On the road around Marsh Barton with AdBlue in a diesel A mile or two after topping up, your engine began playing up: roughness, smoke, lost power, lights on your dash. Marsh Green Road West, say, or the route towards Exeter — a run of under 3 miles. The point: the system has drawn AdBlue through already. Past the fuel filter, along the pipework, and — the more the distance — deeper into the high-pressure pump and every injector. More driving, more starts: deeper it goes. Your move: stop anywhere sensible, then turn your engine off. Marsh Barton sits under 3 miles from the M5; there, pull off at the first junction instead of pushing on for the services. It won't have cleared, so there's no sense restarting to find out. Phone, saying what distance the vehicle went. ## AdBlue in the wrong tank of a hire, lease or company car It's a vehicle you have had for a week. On your own car, AdBlue is absent or elsewhere. On this one, its inlet is just next to the diesel inlet — a surprise to you. Throughout Devon, no one is immune. Put simply: one extra step on top of the cases above, which depend on if it's run. Plenty of hire and company contracts require the owner's sign-off for repairs. Sorting it before we turn up is quicker, and so phone the hire company or your fleet manager, then us. If you are stranded in the car park outside the nearest station, or by Alphington Cross, whilst you wait for an answer, leave the vehicle off. ## Marsh Barton: unsure if it was AdBlue in your diesel tank? Honestly, the only answer may be that you think it did. A faint ammonia-like whiff lingers around your filler, the bottle seems too light, and which cap came off is hard to recall. A hurried top-up by the gates of Alphington Primary School, or a call to a friend in Exeter: either fits. Meaning? Spills around the inlet never reach your motor at all. The diesel tank with AdBlue in it is another matter. Starting the car will not tell you which, and if there is AdBlue in the tank it will suck it in. Do this: act as though it got in, and never start the engine. Inspecting a tank that turns out clean beats emptying one after it has been run — so phone then describe to us what you saw. ## What every AdBlue drain around Marsh Barton has in common The job opens identically, whichever the situation. Anywhere your car is — Crossed Anchors Brewery & Taproom's car park, a road by Alphington Methodist Church, a drive, a filling station — our van arrives and asks about the fluid, the amount, plus if the motor has turned over. Replies set the job; the price comes by phone whilst nobody has set off yet. A thorough flush follows the drain. With petrol it is standard; with AdBlue it's essential, because crystals build up and some metals are attacked, and neither washes away unaided. Clean diesel is put in after your filter is cleaned or replaced, and your car is then tested. Not started? In that case about half an hour on site covers most jobs. We start the car at the end. Before our technicians head off, it is checked to be sure it runs properly on clean diesel. The entire job is done where the car is, and when it is spotted soon, long-term damage is very rare. Nothing is taken upfront, settlement is made on the day, and you receive what your insurer wants: an engineer report and a VAT invoice. Worth knowing: lots of insurers include misfuelling cover, so a quick look at your policy while we travel is worthwhile. ## About Marsh Barton and where it is Marsh Barton is a suburban area located on the riverside in Devon, sitting at an elevation of around 6 metres and close to the city of Exeter.
