--- title: AdBlue in a Diesel Tank Coldhams Common: What Now canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/coldhams-common-cambridgeshire/ location: Coldhams Common county: Cambridgeshire latitude: 52.204990 longitude: 0.157080 service: AdBlue in a Diesel Tank updated: 2026-10-25 --- # What Now? AdBlue in the Diesel Tank in Coldhams Common Has your engine turned over since the AdBlue got in? This single point decides nearly everything about what comes next. Not started so far? Then keep it like that, whether your vehicle sits — Coldhams Common or Cherry Hinton. Phone 0333 366 0103 with the ignition and engine both off. In Coldhams Common, that is typically emptied and cleaned where it stands. Pull over the moment you safely can and switch off, if it has been run. A larger job, yes, yet the same first step. Wherever around Cambridgeshire it happened, one of the cases below fits yours. ## On a Coldhams Common forecourt with AdBlue in a diesel You are at the pump, the nozzle or the bottle still in your hand, and you have just noticed the cap you opened was the wrong one. Perhaps you are at the Camgas, perhaps at the Sainsbury's, perhaps somewhere else in Coldhams Common. Meaning? Finding out here is the best it can be. The AdBlue is in that tank and nowhere else. Nothing has drawn it in. Freeing the pump is no excuse to start it — so do not get back in. Ask the staff to help you roll your car into a parking space, keep the till receipt or the bottle, then phone us from the forecourt. Emptying it right at the petrol pump is possible if it can't be moved, since the equipment is explosion-proof. ## AdBlue in your diesel tank on a Coldhams Common drive? On your dash, a warning had shown for days. Only at the recycling bin, the empty container in hand, did you glance back at the cap you'd used on the driveway. It occurs on drives just off Stourbridge Grove as commonly as anywhere. Meaning? Provided the car hasn't been driven since, it's second to the pump case. Diesel and AdBlue stay separate: the AdBlue drops to the base of the tank and stays there, however long the night. What to do: leave your keys inside the house so nobody moves the vehicle in the morning. Then call. In Romsey Town or right here around Coldhams Common, the drain happens at your driveway. Late-night empties beside a house are fine: the pumps are quiet. ## Drove off with AdBlue in a diesel in Coldhams Common? Lumpy running, smoke, falling power or a lit dashboard arrived a mile or two beyond the fill. Somewhere along Whitehill Close or else heading towards Cambridge — under 3 miles away. Meaning? Your fuel pump has taken the AdBlue in. The high-pressure pump and each injector get it too on a longer trip, once the filter and pipework have had it. Every restart, like each mile, pushes it on. Pull in safely — that's the next job — then switch everything off. Coldhams Common sits under 5 miles from the M11; there, pull off at the next junction rather than pushing on for the services. Restarting it to test achieves nothing — AdBlue never clears on its own. Phone, and say how far the vehicle was driven. ## Hire, lease or company car with AdBlue in the wrong tank You have had this vehicle barely a week. Unbeknown to you, the two inlets are next to each other here — unlike your own vehicle, which has no AdBlue or keeps it elsewhere. Across Cambridgeshire, no one is immune. In short: an extra stage on top of the cases above, which depend on whether it has run. Many rental and company contracts require the owner's approval for work. Do this: hire firm or your fleet manager first, us second, because sorting it beforehand cuts time. If you're stranded in the car park outside Cambridge, or by Christadelphian Hall, whilst you wait for an answer, leave the vehicle off. ## Unsure about AdBlue in the diesel tank around Coldhams Common? Truthfully, the only answer might be that you think so. Lighter, the bottle; a trace of ammonia near your filler; no clear memory of the cap. Sound familiar? Maybe it happened in a hurry at the school gates at St Philip's CofE Aided Primary School, or on a friend's drive in Teversham. In short: a spill round your filler leaves your motor no harm. A diesel tank with AdBlue in it is a different story. You can't tell which by turning the ignition, and doing so would pull in any AdBlue that is in that tank. Next: assume it went in, and keep your motor off. Phone with the details: we'd sooner confirm a tank free of AdBlue than drain one once the engine has been run. ## Coldhams Common: what every AdBlue drain has in common No matter the case, one opening is used. Forecourt, drive, The Empress's car park or a street by The C3 Church — our van reaches the vehicle, and three questions follow: what fluid, what amount, and if it has run. The price is given on the call, before a van leaves, and those replies set the job. A thorough flush comes after the drain. With petrol it's standard; with AdBlue it's crucial, because deposits form and some metals corrode, and neither rinses out unaided. Finally come your filter, cleaned or renewed if necessary; fresh diesel; and a test of your vehicle. Where the motor hasn't run, expect roughly half an hour on site, for most cases. Firing it up comes at the end. Our check that it runs smoothly on new diesel comes before our technicians go. When it is spotted soon, the car very seldom has lasting damage, and the whole 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. Many insurance policies include misfuelling cover, so it is worth checking yours while we're on the way. ## About Coldhams Common itself Coldhams Common is a locality situated near the River Cam in Cambridgeshire, with a mix of terraced housing and local amenities.
