AdBlue in the Diesel Tank in Wexham Court, and What to Do Next
What to do about AdBlue in a diesel tank comes down to one thing more than any other: whether the engine has run since it got in. Not run yet? Then leave the vehicle like that, whether the car sits — Wexham Court or Middle Green. Keep nothing on, ring 0333 366 0103, and expect a thorough flush after a drain, done just where your vehicle stands in Wexham Court. Already run? Stop when you safely can, then switch it off. Stage one remains the same, even though the job is bigger.
Find the situation below that matches yours, wherever across Berkshire it happened.
AdBlue in a diesel on a Wexham Court forecourt
The cap you unscrewed was the wrong one — and you only spot it as you are standing at the pump, bottle or nozzle in hand. Be it BP, Esso or anywhere else around Wexham Court, the case is the same.
Meaning? Spotting it here is the best it gets. Only your tank holds AdBlue; no part past it has taken it in.
What to do: don't get back in and crank it to clear the pump. Ask the staff to help you roll your car into a parking spot, keep the receipt or the bottle, then phone us from the forecourt. Can't move the vehicle beside the pump? Our explosion-proof equipment makes a live forecourt safe, and so it can be drained where it is.
At home around Wexham Court with AdBlue in the diesel tank
On your dash, a warning had shown all week. Bought a container, tipped it in at home, binned the empty — and at that point checked the cap again, too late. Drives close to Moat Drive get it as much as anywhere.
The point: zero driving since makes it nearly as good to finding it at the petrol pump. AdBlue does not mix with diesel; it sinks to the bottom of your tank and waits there. Overnight doesn't change that.
Next: stop any early drive by keeping your keys indoors, then phone us. In Upton Lea or right here in Wexham Court, the draining is done on your drive. The pumps are quiet enough to use outside a house after dark.
AdBlue in a diesel and already driving in Wexham Court?
Lumpy running, smoke, lost power or a glowing dashboard arrived a short way after the fill. Possibly it was on Knolton Way, possibly on the way out towards St Albans, under 25 miles away.
Put simply: the AdBlue has been pulled into the fuel system. Mileage sets how far it goes: filter and lines to begin with, then the injection pump and each injector. Each restart, like every mile, carries it deeper.
Next: find a safe place, pull in, then turn your motor off. Wexham Court lies under 3 miles from the M4; on it, come off at the next junction instead of pushing on for the services. No test restarts: clearing isn't something AdBlue will do. Ring us and say how far you went.
AdBlue in the wrong tank: hire, lease and company cars
It is a motor you have had for a week. On your own vehicle, AdBlue is absent or elsewhere. On this one, its cap is just by your diesel cap — news to you. Anyone, wherever around Berkshire, might make it.
What it means: the same as the scenarios above, depending on whether it's run, with one more stage. Any work on your car often requires the owner's go-ahead under hire or company terms.
Next: phone the rental company or your fleet manager first, then us — sorting it before we arrive is quicker. Stranded by St Mary or at Slough till the firm answers, your vehicle remains switched off the whole time.
AdBlue in the diesel tank? Not sure, in Wexham Court
Truthfully, the only answer might be that you think so. A faint ammonia-like whiff hangs near the filler, the bottle feels too light, and which cap came off is a blur. Perhaps it happened in a hurry at the school gates at Wexham Court Primary School, or on a friend's drive in Slough.
What it means: a little spilled about the filler does no damage to your engine. Inside the diesel tank, however, AdBlue damages it. You cannot tell which by turning the ignition, and doing so will draw in any AdBlue that is in that tank.
Assume it got in, and don't start your engine. Describe what you saw on your phone. A clear tank looked at counts as a happier result than an already-run one emptied.
Wexham Court: what each AdBlue drain has in common
No matter the situation, a single start applies. Forecourt, drive, The George's car park or a road beside Holy Redeemer — our van reaches your car, and three answers follow: which liquid, which amount, and if it ran. The price is given over the phone, ahead of anyone setting off, and those replies shape the work.
AdBlue forms crystals and eats at some metals used in fuel systems, and so it does not wash out on its own; that is why a full flush, after the drain, matters far more with AdBlue than with petrol. The fuel filter is flushed, or replaced where it needs to be; clean diesel goes in; and the car is tested. Where the engine hasn't been started, expect about half an hour on site, for most jobs.
The last step is starting the car. Before our technicians go, it's tested to make sure it runs smoothly on clean diesel. The entire job is done where the car is, and if it is noticed early, permanent damage is very unusual. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. It is worth knowing: many insurers include misfuelling cover, so a check of your policy while we travel pays.
