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

All of it turns on one detail: whether the engine has been run since the AdBlue was added — more than anything else.

Not started yet? Then keep it like that, wherever the vehicle sits — Biscombe or Willand.

Leave the motor and the ignition off and call 0333 366 0103; it's normally a drain and a thorough flush, done where the car is around Biscombe.

If it has run, stop as soon as it is safe then switch off.

It's a larger job, though step one does not change.

Compare what happened to a situation from the ones below, wherever across Somerset you happen to be.

## Biscombe forecourt: AdBlue in a diesel at the pump

Just now, bottle still in hand, you realise that the cap you opened was the wrong one, right at the pump.

It might be the Shell, or the Monument Fuels, or another forecourt in Biscombe.

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

Only your tank has AdBlue; not one component beyond it has taken it in.

Next: resist the temptation to fire it up only to move away from the pump.

A few jobs: a shove into a space with the attendants assisting, the bottle saved, and a ring to us from the forecourt.

If it can't be shifted, it can be drained at the pump: the equipment is explosion-proof and fine on a working forecourt.

## AdBlue in the diesel tank at home around Biscombe

Several days had gone by with the warning light on.

Only at the recycling bin, the empty bottle in your hand, did you look back at the cap you'd opened at the driveway.

Drives close to Downlands Lane get it as much as anywhere.

What it means: if you have not driven since, this is nearly as good as the forecourt.

At the floor of your tank sits exactly where AdBlue waits, because it will not mix with diesel — and a night going by makes no difference.

Next: prevent an early drive by keeping the keys in the house, then phone us.

Your drive is where it gets drained, be it in Biscombe or Carlingwark.

The pumps are quiet enough to use outside a house after dark.

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

Topped up, pulled away, and soon your engine was running roughly, smoking, losing power, or lighting up the dash.

It might have been driving for Exeter, under 25 miles away, or simply along Broad Street.

Put simply: the AdBlue has been sucked through the fuel system.

The injection pump and each injector get it too on a longer trip, once the filter and pipework have had it.

Each mile and each restart takes it further.

What to do: pull over where it is safe to do so and switch off.

Leave by the first junction — not the services beyond — if you're on the M5, under 5 miles from Biscombe.

No trial starts: clearing isn't something AdBlue will do.

Tell us know the distance driven when you call.

## AdBlue in the wrong tank of a hire, lease or company car

A week ago, the car was new to you.

On your own car, AdBlue is absent or somewhere else. On this one, the inlet is right by your diesel inlet — news to you.

Any driver, anywhere in Somerset, might do it.

What it means: the same as the scenarios above, depending on whether it's run, with one more step.

The owner often has to approve any work, under many rental and fleet contracts.

What to do: ring the hire firm or your fleet manager first, then us. That's quicker settled before our technicians turn up than after.

Keep it off as the answer comes, whether you are waiting at Tiverton Parkway or close to Clayhidon Village Hall.

## Not sure it was AdBlue in your diesel tank, Biscombe?

Now and then, "I think so" is the most anyone can honestly say.

A faint ammonia-like smell lingers around the filler, the bottle feels too light, and the cap you took off is hard to recall.

It might have been at a friend's driveway in Rosemary Lane, or rushing by Churchstanton Primary School on the school run.

What it means: a little spilled around your filler does no damage to your engine.

AdBlue inside the diesel tank does.

Any AdBlue in that tank would be sucked in by firing up the car, and the start wouldn't settle which it is in any case.

What to do: treat it as if it was put in. Don't fire it up.

Describe what you noticed on the phone. A clean tank looked at is a better outcome than an already-run one emptied.

## What every AdBlue drain around Biscombe has in common

No matter the situation, one start applies.

Forecourt, drive, the pub in the village's car park or a road by Saint Peter and Saint Paul — our van comes to your vehicle, and three questions come next: which fluid, which amount, and if it has run.

The price is given on the call, before a van leaves, and those replies shape the job.

AdBlue crystallises and eats at some metals in fuel systems, and so it won't wash out unaided; that is why a full flush, after the drain, counts much more here than with petrol.

Last come the fuel filter, flushed or renewed as needed; fresh diesel; and a test of the car.

Not started? In that case about half an hour on site covers most jobs.

We start it last.

Before we go, it is tested to be sure it runs correctly on clean diesel.

If it is noticed early, the vehicle very rarely has long-term damage, and the entire job happens where it is.

Payment is on the day, never upfront. For the insurer, you get a VAT invoice and a report from the engineer.

Many insurance policies include misfuelling cover, and so it's worth checking yours while we are on the way.
