What Now? AdBlue in the Diesel Tank in Farleygreen

One thing counts above all once AdBlue is in a diesel tank, and it is whether the engine has run since. Out in Slip End or here in Farleygreen, an unrun engine must remain that way. Leave your engine and the ignition off and ring 0333 366 0103; it is generally a drain and a thorough flush, done where the vehicle is around Farleygreen. If it has run, stop as soon as it is safe and switch off. It is a larger job, though step one does not change.

Find the scenario below that matches yours, wherever across Bedfordshire it happened.

On a Farleygreen forecourt with AdBlue in a diesel

You're at the petrol pump, the nozzle or the bottle still in your hand, and you have just noticed the cap you opened was the wrong one. Anywhere in Farleygreen, then — BP, Pace, or anywhere else nearby.

Meaning? Spotting it on the forecourt is the best it can be. Only the tank has AdBlue; not one component beyond it has drawn any in.

Freeing the petrol pump is no excuse to start it — so do not get back in. Three jobs: a push into a space with the attendants assisting, the receipt saved, and a ring to us from the forecourt. Stuck beside the pump? Our explosion-proof kit keeps a busy forecourt safe, so it can be drained where it is.

At home in Farleygreen with AdBlue in the diesel tank

The warning light had been on for days. You bought a bottle, poured it in on the driveway, and only when you put the empty bottle in the recycling did you look once more at the cap. Right off Leyhill Drive is not less likely from anywhere.

In short: if the vehicle hasn't been driven since, it's nearly equal to finding out at the pump. Being unable to mix, AdBlue settles low in your tank and waits. A night standing changes none of that.

Keep your keys in the house overnight — otherwise someone might take it away at breakfast — and call us. Our technicians drain it on your driveway, whether that's around Farleygreen or out in Farley Hill. The pumps are quiet enough to use outside a house after dark.

AdBlue drain on a forecourt in Farleygreen

Set off with AdBlue in a diesel around Farleygreen?

You filled up, set off, and a mile or two later the motor began to run unevenly, smoke, lose power or light up the dashboard. Barn Owl Close, perhaps, or the way to St Albans — a run of under 10 miles.

The upshot: your system has pulled AdBlue through already. It's been through your filter and the fuel lines and, the further you went, into your high-pressure pump and the injectors. Each restart, like every mile, carries it on.

Next: find a safe spot, stop, and turn your motor off. Farleygreen sits under a mile from the M1; there, pull off at the first junction instead of pressing on to the services. Restarting it to test gets nothing — AdBlue doesn't clear on its own. Call, and say how far your car went.

AdBlue in the wrong tank: hire, lease and company vehicles

It's a motor you have had for a week. Your own vehicle either does without AdBlue or puts it elsewhere, and so no one warned you the AdBlue inlet was just next to the diesel. Across Bedfordshire, nobody is immune.

Meaning? Whatever applies above applies here — run or not — and one further stage. Any work on the car frequently requires the owner's approval under rental or company agreements.

Next: ring the hire company or the fleet manager first, and then us — settling it before our arrival is faster. Waiting for an answer in the car park at Luton, or beside Farley Hill Jame Masjid? Leave your car off meanwhile.

Farleygreen: unsure whether it was AdBlue in the diesel tank?

Sometimes the fair answer is "I think so". What cap was taken off, you can't recall; but the bottle feels less than expected, and a whiff of ammonia lingers by the filler. The gates of St Margaret of Scotland Catholic Primary School in a rush, perhaps, or a friend's drive over in Caddington.

In short: spillage round the filler does the engine no harm. AdBlue inside your diesel tank does. Firing up the vehicle will not tell you which, and if there is AdBlue in your tank it will draw it in.

What to do: treat it as if it went in. Do not start the car. Describe what you noticed on the phone. A clean tank checked is a happier outcome than a run one drained.

Each AdBlue drain in Farleygreen shares these steps

Whichever situation you are in, the job starts the same way. We come to your car, whether it's at a forecourt, a drive, the car park outside The Plough or a side street near Stockwood Discovery Centre, and ask three things: what got in, roughly how much, and if your motor has run. Your price is given on the call, ahead of anyone setting off, and those replies set the job.

Draining the tank comes first, followed by a full flush — more vital after urea than after petrol, because crystals and corrosion will not clear on their own, however long it sits. Clean diesel is put in once your filter is cleaned or changed, and the car is finally checked. The majority of unstarted cars are a half-hour visit after the moment our engineers arrive.

The last step is firing it up. With clean diesel in, it runs while we make sure it's running smoothly, and then we go. If it is noticed quickly, the vehicle very rarely has lasting damage, and the whole job happens where it is. Nothing is paid upfront, settlement happens on the day, and you receive what the insurer asks for: an engineer report and a VAT invoice. Plenty of insurance policies include misfuelling cover, so it is worth checking yours whilst we are on the way.
