What to do about AdBlue in a diesel tank depends on one thing more than any other: if the engine has run since it went in. Out in Crossgate Moor or here around Whitesmocks, an unstarted engine must remain that way. Switch nothing on, call 0333 366 0103, and expect a proper flush after a drain, done right where the vehicle stands around Whitesmocks. When the engine has run, pull in somewhere safe straight away, then turn the vehicle off. The job is bigger, but the first stage is the same. Find the scenario below that matches yours, wherever in Durham it happened. ## AdBlue in a diesel on a Whitesmocks forecourt Just at this point, nozzle yet in your hand, you realise that the cap you took off was the wrong one, right at the petrol pump. Possibly you're at the Shell, possibly at the Sainsbury's, possibly somewhere else in Whitesmocks. What it means: this is the best location to find out. Just your tank has AdBlue; no part beyond it has taken it in. Freeing the petrol pump is no excuse to start it — so do not get back in. Three jobs: a shove into a space with the staff helping, the bottle kept, and a ring to us from the forecourt. Draining it there at the pump is fine when it cannot be moved, since the equipment is explosion-proof. ## Whitesmocks, at home: AdBlue in your diesel tank Several days had gone by with the warning light on. A bottle from the garage, tipped in at the drive — and it's only at the recycling that the cap got a second look. Houses just off Whitesmocks get hit as often as everywhere else. The point: zero miles since makes it almost as good to spotting it at the petrol pump. AdBlue does not mix with diesel; it sinks to the bottom of that tank and waits there. Overnight doesn't change that. What to do: leave your keys inside the house so nobody moves the car in the morning. Then call. Out in Aykley Heads or here around Whitesmocks, the drain happens at your driveway. Night-time drains beside a house are fine: the pumps are low-noise. ## Drove off with AdBlue in a diesel in Whitesmocks? You filled up, set off, and a mile or two later your motor began to run unevenly, smoke, lose power or light up the dashboard. The Villas, say, or the way towards Durham — a run of under a mile. In short: the AdBlue has been sucked through the fuel system. It has been through your filter and the fuel lines and, the further you went, into your high-pressure pump and your injectors. Each restart, like each mile, carries it on. Next: find a safe spot, stop, and turn the motor off. Whitesmocks sits under 3 miles from the A1(M); on it, pull off at the next junction instead of pressing on to the services. It won't have cleared, and so there is no point starting it again to check. Call, saying how far the vehicle was driven. ## AdBlue in the wrong tank of a hire, lease or company car A week back, it was unknown to you. Unknown to you, the two fillers are next to each other here — not like your own car, which has none or keeps it elsewhere. Anyone, anywhere around Durham, might make it. Put simply: one extra stage on top of the situations above, and those depend on whether it has run. The owner frequently needs to approve any work, under plenty of hire and fleet agreements. Your move: hire firm or fleet manager first, us second, because settling it early saves time. If you are stuck in the car park at Durham, or by Dryburn House, whilst you wait for an answer, leave the vehicle off. ## Unsure about AdBlue in your diesel tank around Whitesmocks? "I think so" is often the most honest as it gets. What cap came off, you can't recall; meanwhile the bottle weighs less than expected, and a whiff of ammonia hangs by your filler. It might have been at a friend's drive in Framwellgate Moor, or rushing outside Framwellgate Moor Primary School on the school run. Put simply: a spill near your filler leaves your engine unharmed. Once it is inside your diesel tank, though, it does. Any AdBlue in that tank would be pulled in by firing up the car, and the start would not settle which it is in any case. Next: act as though it went in, then leave the motor off. Ring with what you saw: we'd sooner confirm a tank free of AdBlue than empty one after the motor has run. ## Every AdBlue drain in Whitesmocks shares these stages Whichever scenario you are in, the job starts the same way. Three questions come when we arrive — at a filling station, a drive, a road by Durham Martyrs' Memorial or the car park at The Cartologist: the liquid, the quantity, and if the motor has been started. Over the phone, before anything else, you hear the quote, and those replies shape the job too. AdBlue crystallises and eats at certain metals used in fuel systems, and so it does not wash out unaided; that is why the flush, after the drain, matters much more with AdBlue than with petrol. Finally come the fuel filter, cleaned or renewed if necessary; fresh diesel; and a test of the car. Most unrun cars are a half-hour job from the moment our engineers get there. The final step is firing it up. We confirm it runs correctly on clean diesel before leaving. Long-term damage is very uncommon if it's spotted soon, and the entire job is done where the car is. For your insurer: an engineer's report and the VAT invoice. For you: payment that day, nothing in advance. It is worth remembering: many insurers include misfuelling cover, and so a quick look at your policy while we travel pays. ## About Whitesmocks Whitesmocks is a suburban area located near the city of Durham, sitting at an elevation of 106 metres in the inland countryside of County Durham.
