# Whittlesford: AdBlue in the Diesel Tank? Find Your Situation

What to do about AdBlue in a diesel tank comes down to one thing more than any other: whether the engine has been run since it was put in.

Out in Heathfield or right in Whittlesford, an unrun motor must remain that way.

Usually this is emptying and thoroughly purging it right there in Whittlesford — so keep your ignition and engine off then ring 0333 366 0103.

Already started? Stop when you safely can, then turn it off.

Stage one remains unchanged, even though the job grows.

Below: the cases our engineers see, anywhere around Cambridgeshire. Pick yours.

## On a Whittlesford forecourt with AdBlue in a diesel

Just now, bottle still in hand, it dawns on you that the cap you took off was the wrong one, there at the pump.

Possibly you're at the BP, maybe at the Esso, perhaps somewhere else in Whittlesford.

The point: of all places to notice, this is the best.

Still in that tank, with no fuel drawn onwards: that is where the AdBlue is.

Clearing the pump is no excuse to run it — and so do not get back in.

Get the attendants to help pushing it to a bay, hold on to the receipt, then phone us right there.

Can't move the vehicle beside the pump? Our explosion-proof equipment makes a busy forecourt safe, and so we can drain the car in place.

## AdBlue in your diesel tank at home in Whittlesford

The warning light had been on for days.

A bottle from the garage, emptied in on the driveway — and it was just at the recycling that the cap caught your eye.

Just off North Road is not less likely from any other place.

The upshot: zero miles since makes it nearly as good to finding it at the pump.

On the floor of the tank is exactly where AdBlue stays, because it will not mix with diesel — and a night passing makes no difference.

Next: the keys in the house, and so no one drives your vehicle anywhere at breakfast. Then, phone.

Your driveway is where it gets emptied, be it around Whittlesford or Sawston.

Even at night, the pumps are quiet enough for a residential street.

## AdBlue in a diesel and already driving around Whittlesford?

Topped up, pulled away, and before long the motor was running unevenly, blowing smoke, losing power, or lighting up your dash.

High Street, perhaps, or the route towards Cambridge — a run of under 10 miles.

What it means: the system has pulled the AdBlue in.

Distance decides how deep it goes: filter and pipework first, then the injection pump and each injector.

Each mile and each restart takes it further.

Stop safely — that is the first step — then switch it off.

On the M11, under a mile from Whittlesford, that means the next junction, not the services further on.

No test restarts: clearing is not something AdBlue does.

Roughly how far did it gone? Tell us as you phone.

## A hire or company car with AdBlue in the wrong tank?

You have just had the vehicle a week.

Unbeknown to you, the AdBlue and diesel fillers sit side by side here — not like your own vehicle, which has no AdBlue or stores it elsewhere.

Anyone, anywhere around Cambridgeshire, could make it.

Meaning? Whatever applies above applies here — run or not — plus one further step.

Work on your vehicle frequently requires the owner's approval under hire or fleet agreements.

Next: phone the hire company or the fleet manager first, then us — sorting it before we arrive is quicker.

Stranded by St Mary & St Andrew (Whittlesford Parish Church) or outside Whittlesford Parkway until someone answers, your vehicle remains turned off throughout.

## Whittlesford: unsure if it was AdBlue in the diesel tank?

"I think so" is sometimes the most honest answer there is.

A slight ammonia smell hangs near your filler, the bottle seems too light, and which cap came off is a blur.

Perhaps it happened in a hurry at the school gates at William Westley Church of England VC Primary School, or on a friend's drive in Hinxton.

What it means: a little spilled around the filler does no harm to the motor.

Once it's inside the diesel tank, though, it does.

You can't tell which by turning the ignition, and doing so would pull in any AdBlue that is in that tank.

Next: act as though it went in, and leave the engine off.

Inspecting a tank that turns out free of AdBlue is better than draining one once it has been run — so ring then tell us what you saw.

## What each AdBlue drain around Whittlesford has in common

Each case gets the same start to the work.

Our technicians come to the car, whether it's on a forecourt, a driveway, the car park outside Tickell Arms or a side street near Whittlesford Memorial Hall, and ask three things: what got in, about how much, and whether the motor has been run.

On the phone, ahead of anything else, you are told the quote, and those replies shape the work too.

A thorough flush follows this drain. With petrol it is standard; with AdBlue it's crucial, because crystals build up and some metals are attacked, and neither rinses out unaided.

Finally come the fuel filter, cleaned or replaced if necessary; fresh diesel; and a test of your car.

Not started? Then about half an hour on site is most jobs.

The final step is firing it up.

Our engineers check it runs properly on fresh diesel before we leave.

If it's caught early, the vehicle very seldom has lasting damage, and the entire job takes place where it is.

You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer.

Worth remembering: lots of insurers offer misfuelling cover, so a quick look at your policy while we travel pays.
