Read This canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/western-hill-durham/ location: Western Hill county: Durham latitude: 54.780880 longitude: -1.585020 service: AdBlue in a Diesel Tank updated: 2026-10-17 --- # Preventing AdBlue in a Diesel Tank in Western Hill: Why It Occurs Keep the engine and ignition off and phone 0333 366 0103 now — the rest can wait if AdBlue is already in the diesel tank. Caught before your motor runs, it is usually a drain and a thorough flush, done where the vehicle is around Western Hill. If you are reading before it has happened, the remainder of this page is about why it occurs and how to make sure it doesn't. ## AdBlue in a diesel motor, and its separate tank Many modern diesels around The Sands, as well as Western Hill, run on two liquids; your motor gets just the diesel. Kept in a tank of its own, AdBlue is fed into your exhaust stream to clean it. Separate tanks, different fillers. Many of cars share a single flap for the two, whereas others move the AdBlue filler to your boot or under the bonnet. At the pump, your diesel side is topped up constantly. A driver who has to stop and think where it goes normally tops up the AdBlue side, from a bottle, and far less regularly. Mistakes happen in that gap between the two. ## How does AdBlue in the diesel tank happen in Western Hill? Seldom is it carelessness: usually three things coincide. On a driveway off North Road before work, or in the car park at The Waiting Room heading home: that is where the rushed top-up happens. What is the reason for the rush? As AdBlue gets low the car tells you, and once it is gone, limp mode follows. Then the vehicle is strange. A hire car, a new motor or a company car puts the fillers where your last one did not, and the hand reaches for the cap it would have used on the old one. Lastly, the spout goes in: a diesel filler or AdBlue filler, it slides in just as easily, and once the pour starts, nothing stops it. The same few seconds settle it, in the middle of Western Hill or out in Durham. ## Telling the AdBlue filler from your diesel filler Be it a Western Hill forecourt or a drive over in Whitesmocks, spend a few seconds on these before anything goes in. - Position can mislead; the cap does not. AdBlue caps are often blue or bear the word "AdBlue" — diesel ones normally do not. - Look at the size: the smaller filler neck is, on many motors, the AdBlue one. - A label inside the fuel flap frequently shows which fuel goes where, on many cars. Check for it. - In your boot or under the bonnet: that is where your filler sits if it's not by the diesel cap, and the handbook tells you which. - Check with the person who drove it last — before you leave, not when the light comes on — if you collect a hire or company car from somewhere like the car park outside Durham. ## Topping up AdBlue without it reaching your diesel tank Anywhere in Durham the light comes on, here is a routine for that day. - Stop somewhere level, engine off, with time in hand — never hurried on the side of Obelisk Lane. - Find the AdBlue filler, check the cap, and speak the name "AdBlue" aloud while you unscrew it. It sounds silly. It does the trick. - If both sit under one flap, check your diesel cap is still closed before you lift the bottle — and leave the car on. - Gently does it, through the bottle's own spout, till it's full or the bottle runs out. - Before you start your car, shut the cap and check a second time that your diesel cap never came off. Find at the second or third stage that the bottle went into the diesel tank? That's where you stop. Stage five is out. ## Western Hill: already put AdBlue in the diesel tank? Brief list, then. First: your engine remains off. On many diesels the ignition alone runs the fuel pump, and so do not switch the vehicle on. Do not top up with diesel to thin it: AdBlue doesn't mix with diesel, it sinks to the bottom of your tank, where your fuel is drawn from. If you are at a forecourt, whether it is the Esso or the Shell, ask the attendants to help push the car away from the pump. If you are on your own drive around Western Hill, leave the car where it is. Already run? Stop once it's safe, then switch off. On the A1(M), under 3 miles from Western Hill, that means the next exit. A short hop across Western Hill is a smaller job than a run towards Durham, under a mile away, so tell us roughly how far it went. ## Our arrival in Western Hill, and what happens next Wherever your car has stopped, whether outside St Margaret's Church of England Primary School, near Obelisk or at home, the van comes to it. Both the work and our price depend on three replies — what liquid, which quantity, and if it's run — so our technicians ask. You get that quote by phone, before anyone heads out. The system is then flushed thoroughly, once your tank is emptied. AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it does not wash out on its own — which is why that matters more here than with petrol. Your filter is flushed, or replaced where it needs to be; clean diesel goes in; and the car is tested. We do not leave until it has been fired up and is running smoothly. Unstarted vehicles usually mean a half-hour job after the moment we arrive. The kit is safe on a live filling station, and hushed enough for a residential street late at night. Payment happens on the day, not upfront, and you receive the documents your insurer wants: an engineer's report and a VAT invoice. It is worth looking at your insurance while we travel to you: misfuelling cover is included with plenty of policies. ## About Western Hill, for a moment Western Hill is a suburban area located on the riverside in Durham, with a mix of terraced housing and a population of around 5220 residents.
