Preventing AdBlue in a Diesel Tank in Common Side: Why It Happens
Leave the motor and ignition off then phone 0333 366 0103 now — the rest can wait when AdBlue is already in your diesel tank. Around Common Side, catching it before your engine runs normally means draining and a thorough flush where it stands. Nothing happened yet? Below, the rest of the page explains the reasons it takes place and the ways to avoid it for good.
AdBlue in a diesel motor: two tanks, two fillers
Diesel goes to your motor — but plenty of modern diesels driven about Common Side and Barlow hold another fluid as well. The exhaust, not your motor, is where AdBlue ends up: dosed into the fumes to clean it, from a separate tank.
Separate tanks, different fillers. Plenty of motors have a single flap for both, while some put the AdBlue filler to the boot or under the bonnet. The diesel side is fuelled at the petrol pump all the time. Someone who has to stop and work out where it goes normally fills the AdBlue side, from a bottle, and much less often. Mistakes happen in that gap between them.
Common Side: how AdBlue in the diesel tank occurs
Seldom is it carelessness: usually three things line up.
The warning comes first. As AdBlue runs low the car tells you, and if it runs out altogether, your vehicle goes into limp mode. So the top-up is done in a hurry: on a driveway off Valley Rise before work, or in the car park at The Tickled Trout on the way home.
Next, the hand reaches for the cap it knew on the old motor — because a rental car, a new vehicle or a company car puts the fillers where your last one did not.
A spouted bottle finds no obstacle at a diesel filler no more than at an AdBlue one. So the tip, once begun, carries on. Whether it happens in Crowhole or the middle of Common Side, it's the same few seconds.
Which filler is for AdBlue, and which for diesel?
A couple of seconds is all the checks take — so run through them before you tip anything, on a driveway in Brindwoodgate or a forecourt around Common Side.
- Check the cap rather than going by where it sits: AdBlue ones are often blue or marked "AdBlue", and diesel ones normally aren't.
- Many cars give AdBlue the smaller neck of the two.
- Check inside your fuel flap: plenty of vehicles carry a label there saying which fuel goes where.
- Can't see it beside the diesel filler? In that case look below the bonnet or inside your boot — the handbook will say which.
- Check with the person who drove it last — before you leave, not when the light comes on — when you pick up a hire or company car from somewhere like the car park outside Dronfield.
Topping up AdBlue without it reaching your diesel tank
Wherever across Derbyshire the light comes on, here is a routine for the day.
- Not in a rush on the side of Mill Street, not on a slope, not with your motor running: park and switch off properly.
- Say "AdBlue" out loud as you unscrew the cap, after you find the AdBlue filler and read it. Daft, perhaps, yet it works.
- If both sit under one flap, check the diesel cap is still closed before you lift the bottle — then leave it on.
- Pour slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty.
- Only then, start your car: close the cap, check a second time, and make sure your diesel cap was never opened.
Find at stage two or three that it's already gone into the diesel side? Then stop just there. Never go on to step five.
Already put AdBlue in the diesel tank in Common Side?
Don't start your engine: that is where the short order of things begins. Do not switch your ignition on; on many diesels that alone runs the fuel pump. 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 pulled from.
The staff at JET, Sainsbury's or any forecourt will normally help to push your car clear if you ask. At home around Common Side? So your car stays where it is.
Already run? Pull over when it is safe, then switch off. On the M1, under 10 miles from Common Side, that means the next exit. Mileage matters — a short hop across Common Side makes a smaller job than driving under 10 miles towards Sheffield — so say roughly how far it went.
When we get there around Common Side, what occurs?
Our technicians come to the car wherever it has stopped, whether that is outside Barlow CofE Primary School, near Barlow & Cutthorpe Methodist Church or on your own driveway. We ask what got in, about how much, and whether it's run, because those answers decide the work and our quote. No one heads out before you've heard our quote over the phone.
Then your tank is emptied and your system flushed thoroughly. Unlike petrol, AdBlue forms crystals and attacks some fuel-system metals, and neither washes away unaided. That is why it counts more. Once the fuel filter has been flushed — or replaced, where required — fresh diesel is added, and finally the car is tested. We do not go until it has been started and is running correctly.
If the engine hasn't run, the majority of jobs take about half an hour once we are there, using pumps that are fine on a busy forecourt and quiet enough to use outside a house after dark. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. It is worth checking your policy while we travel to you: misfuelling cover comes with many policies.

AdBlue drains about Common Side, and Derbyshire beyond
Being a village, Common Side shares its vans nearby places — Newgate, Peakley Hill — all the way across S postcodes and the surrounding area beyond. A postcode starting S18 7 gets our van to you fastest.
Shifting your car is not needed. We drain it where it is — a side street near Barlow Village Hall, a lay-by on the way to Lees Plantation, a driveway. If you're close to a boundary, or somewhere hard to describe like the back of St Lawrence, ring and ask rather than guessing.

Always, the cap; after that, the tip. Petrol in Diesel empties it where it stands, anywhere across Derbyshire, if AdBlue has gone in the diesel tank all the same — so leave the car off and phone 0333 366 0103.
