--- title: Old Lakenham: AdBlue in a Diesel Tank? Don't Start canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/old-lakenham-norfolk/ location: Old Lakenham county: Norfolk latitude: 52.605490 longitude: 1.295100 service: AdBlue in a Diesel Tank updated: 2026-10-18 --- # AdBlue in the Diesel Tank in Old Lakenham? Keep It Switched Off AdBlue in the diesel tank? Then keep your motor off — and your ignition too. Urea dissolved in water is what AdBlue is. It doesn't burn, it doesn't mix with diesel, and the harm it does starts when the fuel system draws it in. A drain and a thorough flush, done where your car is around Old Lakenham, is usually all AdBlue in a diesel tank needs — if it's caught before the motor has been run. Nothing comes before calling 0333 366 0103. ## Those opening minutes: AdBlue in the diesel tank around Old Lakenham Things to do: - Pull the keys out, so no one switches your ignition on. - Put your hazards on if you're anywhere near moving traffic. - The empty bottle or the till receipt tells us the product and the quantity, and so don't throw it away. - Call us from where you are. A postcode starting NR1 2, or the name of the closest street, brings the van to you without a search. Do not: - Not even briefly, and not to roll your car: your motor stays off. - Your ignition stays off: on many diesels, turning it on is enough to start your fuel pump. - Adding more diesel does not help: AdBlue settles out instead of blending. - Even a short stretch along Sandy Lane is too far to drive the vehicle. - Emptying the tank on your own by the road is not worth trying. On a forecourt around Old Lakenham, whether it's the Asda or another one, ask the staff to help you push the car away from the pump. If you're on your own drive, leave it precisely where it sits. ## What does AdBlue do in a diesel tank? Not the engine but the exhaust is where AdBlue is meant to go. It goes into its own tank and is sprayed into the exhaust gas to clean it. A fuel pump isn't designed to cope with it, and AdBlue was never supposed to travel through one. Inside a diesel tank it behaves very differently from fuel. It doesn't mix in. The intake takes fuel from the deepest part of your tank, and that is just where AdBlue settles: as it is denser than diesel, it sinks. A vehicle topped up on a driveway in Eaton Rise overnight and not started since is the simple case. No pump has pulled the AdBlue up so far — though when the motor runs, that is what is pulled first, straight from the bottom of your tank. Once it's sucked in, the damage comes in two forms. What remains when the water evaporates is urea, which turns into crystals: they lodge in tiny channels and block filters. On top of that, it eats at some metals in the fuel system, and keeps going until it is cleared out. Overnight, a car parked around Old Lakenham with AdBlue through its pipework grows worse; if it's only in your tank, nothing changes. Diesel protects the injection pump and each injector as it passes; water gives no lubrication, and that is a separate form of damage. ## Petrol or AdBlue in a diesel: why AdBlue is often worse Fill a diesel with petrol by mistake over at the BP, and the issue is thinned fuel. Mixed into the diesel and left unused, it is no threat at that stage; using the motor is the damage. The trouble with AdBlue in a diesel is a completely unsuitable liquid. It does not burn, and so it can't simply be run through. It doesn't stay mixed, so it can't be thinned. And crystals and corrosion don't wash out with the next tank of fuel. That's why the flush matters more with AdBlue than with petrol, and why starting the engine "to see" costs more here than nearly anywhere else, whether your car is in Trowse Millgate or the middle of Old Lakenham. With AdBlue, the good news is no distinct from petrol. Not run? Then the AdBlue waits only inside that tank, the simplest bit of the whole system to clear, wherever the car has stopped across Norfolk. ## How AdBlue ends up in a diesel tank around Old Lakenham It is not deliberate. Many cars keep the AdBlue cap alongside the diesel one, occasionally under a single flap, and muddling them up is easy after dark. Most of the time it happens with a bottle bought on the way home and poured in on the drive, not at the pump. Mostly, it takes place in one of a couple of familiar ways. The top-up gets rushed outside Edith Cavell Academy and Nursery, because the dash flashed with a warning as the kids were taken in. A bottle is poured in at the end of the day on a drive just off De Berney Close. Or someone new to that flap refills your car in dim light, parked in the car park by Shoe Makers. Hired motors, new motors, fleet motors, or the spare car in a family with one of each: the least known vehicles see it the most. Anywhere in Norfolk, Old Lakenham included, the slip doesn't change, and neither does the first step: leave it switched off. ## Started the engine with AdBlue in the diesel tank around Old Lakenham? If so, the AdBlue is no longer in that tank. With any running, it goes on to the high-pressure pump and each injector, having passed through your filter and lines. Maybe coming back from Lea Bridges Park, or part way across Old Lakenham, the engine may run rough, smoke, drop power, flash the dash or stall. Stop as soon as it is safe, switch off, and do not restart the car to check. Each start pulls more of that through. If you were on the M11, over 50 miles from Old Lakenham, come off at the next exit and stop somewhere sensible instead of pressing on. How far it went counts. A few hundred yards across Old Lakenham to the car park by Al-Madinah Muslim Community Centre is a very different job from a run towards Norwich, under 3 miles away, with the AdBlue reaching further into the system with every mile. About how far it had come is worth telling us. Wherever the vehicle came to a stop is where all of it gets done, even with more to clean out after the engine has been run. Very seldom does it leave permanent damage if it's noticed early. ## Draining AdBlue in a diesel in Old Lakenham: what it takes The vehicle remains where it is, whether that's a road near Saint John the Baptist and All Saints, a drive, a lay-by or a forecourt around Old Lakenham, and the van comes to it. The work depends on three replies, and our engineers ask for before all else — which fluid went in, the quantity, and whether your motor has turned over. On the spot, your tank is then drained, and all of the contaminated diesel and the urea leave at once. A full flush counts far more with AdBlue than after petrol, because residue will not clear away by itself. Next, the fuel filter: flushed, or changed if it has to be. After that fresh diesel, and then a test of your vehicle. Most of these jobs are a half-hour job once our technicians get there, provided the motor hasn't run. The equipment is explosion-proof, so a live forecourt is no issue, and it's hushed enough for a residential street late at night. Fresh diesel goes in to bleed the system, and that's the last step. Whether it's a parking space by Norwich or a drive in Old Lakenham, that is where we fire it up and you drive off. Our engineers make sure it runs correctly on new diesel before we leave. Our engineers do it all wherever the car has stopped, and it never has to be taken to a garage. You get a VAT invoice and an engineer report afterwards, which is what insurers want. ## About Old Lakenham itself Old Lakenham is a suburban area situated near the River Yare in Norfolk, with a mix of semi-detached housing and local amenities. Old Lakenham lies close to the city of Norwich, approximately 1.6 miles from the city centre, and is near other local areas such as Long Johns Hill and Tuckswood. Old Lakenham has a relatively low elevation of around 9 metres above sea level, reflecting its riverside setting. Old Lakenham is home to around 3132 residents, according to approximate population figures. ## Old Lakenham and Norfolk: AdBlue drains across the area Long Johns Hill, Tuckswood and Lakenham are among the places around Old Lakenham that the same teams reach, together with much of Norfolk further out, over the NR postcode area. Phone and ask instead of guessing if you are by a county line, or somewhere awkward to explain. No moving is needed. In Old Lakenham, a residential suburb, a van that comes to you fits: the vehicle is drained on the spot, be it on a driveway, a side street, a parking area or a filling station. ## Old Lakenham: what AdBlue in a diesel tank costs to fix No single figure would be honest, since each job differs. What changes the cost is, firstly, whether your engine has run and for how long; then how much AdBlue got in; and then where the car is and whether a van can get to it safely, which is simpler on an open drive than in a tight gap behind Old Lakenham Community Centre. For that in mind, each enquiry from Old Lakenham opens by asking the same trio — which fluid got in, how much, whether the engine ran — before any quote. The replies turn a range into a straight quote. Priced by phone before the van sets out, the job is settled that day — card or phone, nothing in advance. Look at your policy whilst we're on the way: many include misfuelling cover. ## Old Lakenham: still alongside the car? In that case, touch nothing — that's the most helpful step available. Motor off, keys out, ignition off. Say it was AdBlue, roughly how big an amount, and whether the engine ran, on 0333 366 0103. From there Petrol in Diesel handles it, across Old Lakenham or wherever in Norfolk.
