AdBlue in the Diesel Tank in Walsworth: What Now?
What to do about AdBlue in a diesel tank depends on one thing more than any other: whether the engine has run since it got in. If it has not, keep it that way, whether the car is in Walsworth itself or out in Oakfield. Leave the engine and your ignition off and call 0333 366 0103; it is usually a drain and a thorough flush, done where the car is around Walsworth. Already run? Pull over once you safely can, then turn it off. A larger job, then, yet the identical opening move.

Walsworth forecourt: AdBlue in a diesel at the pump
The cap you unscrewed was the wrong one — and you only notice it while you're standing at the petrol pump, bottle or nozzle in hand. Possibly you're at the Esso, perhaps at the Shell, perhaps somewhere else in Walsworth.
In short: no better place exists to spot it. Nothing has drawn it through, and so the AdBlue stays only in that tank.
Clearing the petrol pump is no reason to start it — and so do not get back in. Phone us from the forecourt once your vehicle sits in a space — the staff will lend a hand to push it — and keep the receipt. Can't move it by the petrol pump? Explosion-proof equipment keeps a live forecourt safe, and so we can drain the vehicle in place.
AdBlue in your diesel tank on a Walsworth drive?
The warning light had been on for days. Picked up a container, poured it in at home, recycled the empty — and only then looked at the cap again, too late. Right off Orchard Road is not less likely from any other place.
The point: zero miles since makes this almost as good to spotting it at the petrol pump. AdBlue doesn't mix with diesel; it sinks to the bottom of that tank and waits there. Overnight doesn't change that.
Next: keys in the house, and so no one drives the car off first thing. After that, ring. Your driveway is where it is drained, whether around Walsworth or Purwell. The pumps are quiet enough to use outside a house at night.
Drove off with AdBlue in a diesel around Walsworth?
A mile or two after filling up, your engine began misbehaving: roughness, smoke, lost power, lights on the dash. Possibly it was on Woolgrove Road, maybe on the way out towards St Albans, under 15 miles away.
What it means: the system has pulled the AdBlue in. Mileage sets how far it gets: filter and pipework to begin with, then the injection pump and each injector. Each mile and each restart takes it further.
Next: pick a sensible spot, pull in, then switch the motor off. Exit at the first junction — not the services further along — if you are on the A1(M), under 3 miles from Walsworth. No trial restarts: clearing is not something AdBlue will do. Ring us and say how far you drove.
A hire or company car with AdBlue in the wrong tank?
It is a vehicle you have had for a week. Your own motor either does without AdBlue or puts it elsewhere, so no one warned you the AdBlue cap was right beside your diesel. Any driver, wherever in Hertfordshire, might make it.
The point: just as above, split by whether it ran, but with an added step. Work on your vehicle often needs the owner's approval under rental or company terms.
What to do: call the hire firm or your fleet manager first, then us. That is faster settled before our technicians arrive than after. Stranded by Walsworth Community Centre or outside Hitchin until someone answers, the car stays switched off the whole time.
AdBlue in the diesel tank? Not sure, around Walsworth
Occasionally the fair answer is "I think so". The bottle is lighter than it should be, there's a faint smell of ammonia around your filler, and you can't remember which cap you took off. A rushed stop by the gates of Highover Junior Mixed and Infant School, or a call to a friend in Ickleford: either fits.
Meaning? Drips around the filler never touch your motor at all. In the diesel tank, by contrast, AdBlue harms it. If there is AdBlue in your tank, firing up your car will suck it in, and it wouldn't tell you which either.
Assume it went in, and never turn the key. Phone with what you saw: we would rather find a tank free of AdBlue than empty one after your engine has been run.
The common ground in each Walsworth AdBlue drain
No matter the situation, a single start applies. Our technicians come to the vehicle, whether it's at a forecourt, a driveway, the car park at The Anchor Inn or a side street close to Walsworth Meeting Room, and ask three things: what went in, roughly how much, and if your motor has run. On the phone, before anything else, you are told our price, and those replies shape the job too.
AdBlue forms crystals and is corrosive to some metals in fuel systems, and so it won't wash out on its own; that's why a full flush, after the drain, matters much more with AdBlue than with petrol. Last are the fuel filter, flushed or renewed as needed; clean diesel; and a test of the car. Never started? Then about half an hour once we are there covers most jobs.
Last, we fire it up. With fresh diesel in, it runs while our engineers check it is running correctly, and then we leave. When it is noticed quickly, the vehicle very seldom has permanent damage, and the whole job happens where it is. For your insurer: the engineer's report and the VAT invoice. For you: payment on the day, no money upfront. It is worth remembering: many insurers include misfuelling cover, and so a check of your documents while you wait is worthwhile.
