Why It Happens and How to Prevent It: AdBlue in a Diesel Tank in Seedley
Stop here for a moment when the diesel tank already holds AdBlue in it: ignition off, motor off, then ring 0333 366 0103. Caught before the engine runs, it's usually a drain and a thorough flush, done where the vehicle is in Seedley. If you're reading before it has happened, the remainder of this page is about why it takes place and how to make sure it does not.
AdBlue in a diesel car, and its separate tank
Many newer diesels around Brindle Heath, like those in Seedley, run on two liquids; your motor gets just the diesel. AdBlue goes to your exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own.
Each tank has its own filler. Other vehicles put the AdBlue filler in the boot or under the bonnet; a lot of others have the two together under one flap. At the pump, your diesel side is topped up all the time. Someone who has to stop and work out where it goes normally tops up the AdBlue side, from a bottle, and far less often. It's in that gap that the slip lives.
How AdBlue in your diesel tank occurs around Seedley
It is rarely carelessness. Three things tend to line up.
On a driveway off Derby Road before work, or in the car park at Ashley Brook heading home: that's where the rushed top-up takes place. Why the rush? As AdBlue runs low the car warns you, and once it is empty, limp mode follows.
Next, the hand goes for the cap it knew on the old car — because a rental car, a new motor or a company car places the fillers somewhere your last one did not.
Lastly, the bottle fits: a diesel filler or AdBlue filler, it slides in just as readily, and after the pour begins, nothing stops it. Whether it takes place in Weaste or the middle of Seedley, it's the same few seconds.
Which filler is for AdBlue, and which for diesel?
Be it a Seedley forecourt or a drive out in Salford Quays, take a few seconds over these before anything goes in.
- Read the cap instead of going by where it sits: AdBlue ones are commonly blue or marked "AdBlue", and diesel caps usually are not.
- Check the size: the smaller neck is, on plenty of motors, the AdBlue one.
- The flap. Look inside your fuel flap for a label. Many cars say there which fuel goes where.
- Cannot see it next to your diesel inlet? Then check below the bonnet or in your boot — the owner's manual will say 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 Salford Crescent.
AdBlue top-ups that never reach the diesel tank
For the day the warning appears — anywhere it is across Greater Manchester — a routine to use.
- Park and switch off. Not on a slope, not with the engine running, and not in a rush on the side of Cressington Close.
- Say "AdBlue" out loud as you unscrew the cap, after you find the AdBlue filler and read it. Daft, perhaps, yet it works.
- Both behind a single flap? So confirm the lid on your diesel side is still closed ahead of raising the bottle.
- Using the bottle's own spout, pour slowly — and stop when it's full or the bottle is empty.
- Close the cap and check a second time. Make sure the diesel cap was never opened. Only then start your car.
If at stage two or three you find you have already poured into your diesel side, stop there. Never go on to stage five.
Seedley: already put AdBlue in the diesel tank?
Then the order of things is short. Do not start the motor. On many diesels your ignition alone runs the fuel pump, and so do not switch the car on. AdBlue doesn't mix with diesel — it sinks to the bottom of your tank, where the fuel is pulled from — so do not top up with diesel to thin it.
At a forecourt — BP, Tesco or any other — the attendants will normally help push the car clear, if you ask. Your own driveway in Seedley is where it stays.
If your engine has already run, stop as soon as it is safe then switch off. The next exit means the place to leave if you're on the M602, under a mile from Seedley. Mileage counts — a quick hop across Seedley makes a smaller job than heading under a mile to Salford — so tell us roughly how far it went.
When our engineers arrive around Seedley, what happens?
Wherever the car came to rest, be it outside Willow Tree Primary School, near Saint Lukes Church or at home, the van comes to it. We ask what got in, about how much, and if it has run, because the answers decide this work and our quote. During the phone call itself, you are told our price — ahead of anything else.
Your system is then rinsed thoroughly, after that tank is emptied. Not like petrol, AdBlue leaves crystals and eats at some fuel-system metals, and none of that washes away unaided. That is why it counts more. Once the filter has been flushed — or renewed, if needed — clean diesel goes in, and finally the vehicle gets tested. We don't leave until it has been started and is running correctly.
Unrun cars mostly need a half-hour visit from arrival. The equipment is fine on a live forecourt, and hushed enough for a residential street after dark. Paying is on the day, not upfront, and you receive the documents an insurer asks for: an engineer report and a VAT invoice. Plenty of insurance policies include misfuelling cover, so it's worth checking yours whilst we're on the way.
