Avoiding AdBlue in a Diesel Tank in Temple Fortune: Why It Occurs

AdBlue in a diesel vehicle: two tanks, two fillers

Diesel feeds your engine — but plenty of current diesels seen round Temple Fortune and Hampstead Heath hold another fluid as well. Its own tank keeps it, and from there it goes to the exhaust, and there a spray cleans the fumes.

There's a filler on every tank. Plenty of motors have a single flap for the two, whereas some move the AdBlue filler to the boot or under the bonnet. Topping up your diesel side at the pump goes on all the time. Seldom filled, AdBlue usually comes from a bottle, poured by a driver who must stop and think which cap to use. That gap is where the slip lives.

Which filler is for AdBlue, and which for diesel?

Be it a Temple Fortune forecourt or a driveway over in Brent Cross, take a couple of seconds on these before anything is poured in.

• The cap. The AdBlue cap is commonly blue, or marked "AdBlue". Your diesel cap normally is not. Read it instead of going by position.
• On plenty of cars, the size gives it away: AdBlue gets the smaller filler neck.
• The flap. Look inside your fuel flap for a label. Many vehicles say there which fuel goes where.
• Can't see it next to your diesel filler? Then check below the bonnet or inside the boot — the handbook says which.
• Whoever had it before will know. Check as you pick up a hire car or company car — from Brent Cross West's car park, perhaps — rather than when the warning appears.

What happens when our technicians arrive around Temple Fortune

By Garden Suburb Junior School, close to Farm Walk Lawn Tennis Club or on your own drive: wherever your car has stopped, our technicians come to it. Which fluid got in, the quantity, and if it ran: we ask because those replies set the work and quote. During the phone call itself, you hear our price — ahead of anything else.

Your system is then rinsed thoroughly, after the tank is cleared. Unlike petrol, AdBlue leaves crystals and eats at certain fuel-system metals, and none of it washes away by itself. Hence it counts more. Your filter is cleaned, or replaced where it needs to be; clean diesel goes in; and the car is tested. Then our technicians start it and check it runs smoothly before leaving.

Unrun cars usually need a half-hour job from the moment we arrive. The equipment is safe on a busy filling station, and quiet enough for a driveway after dark. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. It is worth checking your insurance as the van travels to you: misfuelling cover is included with many policies.
