Penmaen Rhos: AdBlue in the Diesel Tank? Leave It Off
AdBlue in the diesel tank? Then keep the engine off — and your ignition as well. Urea dissolved in water is what AdBlue is. Not like fuel, it neither ignites nor blends, and no harm starts till your engine pulls it through. If your motor has not run yet, AdBlue in a diesel tank is generally emptied and carefully flushed where your car stands in Penmaen Rhos. First, ring us on 0333 366 0103.
Penmaen Rhos, AdBlue in your diesel tank: what to do right away
Things to do:
- Pull your keys out, so no one switches your ignition on.
- If you're at all close to moving traffic, put the hazard lights on.
- So you can tell us which liquid it was and about what quantity, keep your receipt or the empty bottle.
- Give us a postcode starting LL29 9, or whichever street is closest, and our van reaches you straight — so call wherever you are.
Not to do:
- Don't start your motor, even for a moment to shift your car.
- The ignition stays off: on many diesels, turning it on is enough to run the pump.
- Do not top up with diesel to dilute it. AdBlue does not mix in diesel; it separates out.
- Any driving at all is to be avoided, including a short stretch along Sŵn y Don.
- Emptying the tank yourself beside the road isn't worth trying.
Ask the people behind the counter to help you move the car off the pumps if you are at a forecourt in Penmaen Rhos, whether it is the the nearest petrol station or elsewhere. If you are on your own drive, leave the car just where it sits.
What does AdBlue do in a diesel tank?
The engine isn't what AdBlue is made for; the exhaust is. Its own tank keeps it, and from there it's fed into your exhaust, where it cleans the fumes. Nothing in it is meant to pass through a fuel pump, and nothing in a fuel pump is built to handle it.
Fuel mixes; AdBlue, after tipped in, will not. Its behaviour is nothing like fuel's. It is heavier than diesel, so it sinks and collects at the bottom of the tank, which is where the pickup sucks fuel from. Once the pump runs, the AdBlue is top of the list to go through. Until then it sits beneath the diesel, and that is why a car filled in Llysfaen yesterday and not started stays the simple case, provided no one touches the key.
Once it's pulled in, the harm takes two forms. As its water goes, the urea left behind crystallises, and the crystals block filters and settle in fine passages. And it's corrosive to some of the metals a fuel system is made from, so it keeps running on the components it reaches for as long as it remains there. A car left standing around Penmaen Rhos with AdBlue already in its lines is worse by the morning; one with AdBlue only in its tank isn't. Water protects nothing. The high-pressure pump and every injector depend on diesel running through them, and so the water part damages them by itself.
Why AdBlue in a diesel is regularly more serious than petrol
Petrol pumped into a diesel on Shell's forecourt leaves the fuel watery — that is the main fault. It mixes with the diesel, and while it is in that tank it does no harm; the harm comes from running your motor on it.
The trouble with AdBlue in a diesel is a completely unsuitable liquid. It cannot just be run through, since it does not burn. Whether the car sits in Colwyn Bay or the heart of Penmaen Rhos, turning it over "to see" costs more with AdBlue than nearly any other mistake, and the flush matters for more. The reasons: it will not stay blended, so watering it down fails; and deposits and corrosion outlast the next tankful.
The good news is the same as with petrol. Clearing a tank is the simplest part on a fuel system, and without start-up, the AdBlue remains in there — wherever across Conwy your vehicle has stopped.
How does AdBlue end up in a diesel tank around Penmaen Rhos?
It's not on purpose. Many vehicles have the AdBlue cap beside the diesel one, occasionally under a single flap, and muddling them up is simple after dark. A bottle picked up while heading home and tipped in outside the house, instead of at the forecourt, is the usual story.
The ways it takes place are few and familiar. The top-up gets hurried outside the local primary school, after your dash lit up with a warning while the children were dropped in. Near Ffordd Elias, someone tips a container in at home in the evening. Or the vehicle is topped up in the car park at The Semaphore Lodge - Choi's Chinese restaurant, in poor light, by a person who has never opened that flap before.
Hired vehicles, new cars, company motors, or the spare vehicle in a home with one of each: the least familiar vehicles see it most. Keep it switched off: that's the first response to an identical slip, wherever in Penmaen Rhos or the remainder of Conwy you are.
Already started your engine with AdBlue in the diesel tank in Penmaen Rhos?
Then the AdBlue has left your tank. Via the fuel filter, through the lines, and — with any running — on to the high-pressure pump and every injector: that's how far it has gone.
Expect rough running, smoke, falling power, warnings on your dash, or a cut-out — returning from Wynn Gardens, perhaps, or midway across Penmaen Rhos. When you safely can, stop then turn everything off — without restarting to test. Each start pulls more of that through.
On the Moreton Spur, under 25 miles from Penmaen Rhos, the next junction is where to exit, and somewhere sensible is where to park — not driving on.
How far it went counts. A couple of hundred yards across Penmaen Rhos to the car park by Chuz Rock is a very different job from a run towards St Asaph, under 10 miles away, with the AdBlue reaching further into the fuel system with every mile. Tell us roughly how far it had come.
Our engineers do all of the cleaning where the vehicle has come to a stop, and once your engine has run there is more of it. When it's caught early, permanent damage is very unusual.
What does an AdBlue drain on a diesel involve in Penmaen Rhos?
A street beside Old Colwyn Methodist Church, a drive, a lay-by or a forecourt: wherever the car has come to rest around Penmaen Rhos, our engineers come to it. What went in, roughly how much, plus whether the motor has turned over: our technicians ask first, because those shape the work.
Next, draining that tank right there takes out the contaminated diesel along with the AdBlue in one go. Your system is rinsed thoroughly, which counts more with AdBlue than with petrol, because what it leaves behind doesn't rinse out on its own. Clean diesel goes in after the filter is flushed — or replaced, if it needs to be — and after that your vehicle is tested. Roughly half an hour once we arrive is typical for most jobs where your engine hasn't run. Explosion-proof pumps mean a busy forecourt sensible to work on, and they run quiet enough not to disturb the neighbours at night.
New diesel goes in to prime the system, and that's the last step. You drive off as soon as our engineers have started the engine, and it makes no difference whether the vehicle is on a drive around Penmaen Rhos or in a bay by Colwyn Bay. Before we go, our technicians make sure it is running correctly with fresh diesel in. Since the job is done in full where the vehicle is, a garage never comes into it. You get a VAT invoice and an engineer report after that, which is what insurers ask for.

What AdBlue in a diesel tank costs to put right around Penmaen Rhos
There's no honest single quote, since the jobs are not the same. The price moves first with how long, if at all, the engine has been running, and next with the quantity of AdBlue that went in. After that it turns on where your car is and whether our van can reach it safely, which is easier on an open drive than in a tight gap behind Llysfaen Village Hall.
What was put in, how much, and if it ran: every Penmaen Rhos call opens by asking precisely those, before any quote, never afterwards. Once they are answered, a range turns into a single fixed figure.
Before a van heads out, you hear the quote by phone. And you pay on the day, by card or over the phone, with nothing in advance. Plenty of insurance policies include misfuelling cover, so it's worth checking yours whilst we are on the way.
