A named engineer for Kent, not a call centre
One engineer covers the county, so the person who quotes the job is the person who does it. You get his name before the appointment.
He has over twenty-five years in the trade and is the director of both Remaps UK and JF Automotive. AdBlue, DPF and EGR deletes are most of what he does on the road; the repairs he does at JF Automotive.

Check we cover you →AdBlue fix, or AdBlue delete, in Kent
A delete is a software job John does on your driveway, priced from the registration. A repair is workshop work, so the car goes to JF Automotive in Maidstone, where it is diagnosed properly and put right. Which one you go for is up to you. The full explanation of each is on the AdBlue page.
AdBlue fix in Kent
The car goes to JF Automotive in Maidstone, the workshop we are part of. They read the codes and the live SCR data on the ramp, find the part that has failed and replace it. The warning clears, the countdown resets and the car stays as it was built. We do not come out to diagnose it first; the workshop does that and the repair in one go.
Book it in for a repairAdBlue delete in Kent
The SCR system is switched off in the engine ECU, on your driveway, from the original file, which we keep. The warnings, the countdown and the limp mode stop and the car no longer uses AdBlue. It takes about an hour, it is priced from the registration before we come, and the price does not change on the driveway.
Get a price for a deleteNine AdBlue faults, and what they are
These account for nearly every AdBlue warning we see in Kent. They all feel identical from the driver's seat, which is why a repair is diagnosed on the ramp at JF Automotive before it is priced.
- NOx sensor failure - the commonest, and the one most often mistaken for low fluid
- Engine limp mode from an AdBlue fault - reduced power until the system can prove it is working
- Recurring AdBlue system problems - cleared by a garage, then back again within a week
- Software faults in the SCR control - the hardware is fine and the ECU still refuses to believe it
- Urea quality and fluid messages - contaminated, diluted or old AdBlue in the tank
- AdBlue level sensor fault - a full tank read as empty
- AdBlue pump faulty - cannot build or hold dosing pressure
- AdBlue injector fault - crystallised or blocked, so nothing reaches the catalyst
- AdBlue malfunction warnings and countdowns - the message that brought you here
From the warning to a car that starts
Tell us what the dash says
Send us the registration, the message, roughly what the counter shows, and whether you want it deleted or repaired. It takes a minute on the form below.
A fixed price, usually the same day
For a delete, one figure from the registration. For a repair, we pass you to JF Automotive and they book the car in.
We send you a booking link
For a delete, pick a time at home or at work; John's name is on the booking. For a repair, the booking is with the workshop.
The delete applied, or the repair done
For a delete, the original file is read and kept and the new one written, there on the driveway. For a repair, JF Automotive read the codes and live SCR data on the ramp, find the failed part and replace it.
Road test and done
The car is driven to prove the warning has gone and the counter has reset. A delete takes around an hour all in.
How the AdBlue system works, and why it fails
AdBlue is a solution of 32.5 per cent high-purity urea in deionised water, made to the ISO 22241 standard so that every bottle behaves the same way. It is not a fuel or an additive. It sits in its own tank, usually 10 to 20 litres with a blue filler cap, and is sprayed into the exhaust ahead of the SCR catalyst.
In the hot exhaust, above about 200 C, the urea breaks down into ammonia. Inside the catalyst the ammonia reacts with the nitrogen oxides the engine produced and turns them into nitrogen and water vapour. Done properly it removes most of the NOx, and it works best with the catalyst between roughly 250 and 450 C.
A car uses AdBlue at roughly 2 to 6 per cent of its diesel consumption, so a tank lasts somewhere between 5,000 and 10,000 miles depending on the car and how it is driven.
Why it goes wrong
The engine ECU controls the dosing pump, the injector and the tank heater, and it reads the level sensor, the quality sensor and two NOx sensors, one before the catalyst and one after. It compares what went in with what came out. If the numbers do not add up, or a sensor stops answering, it logs a fault, lights the lamp and starts the countdown, because by law it must not let the car run indefinitely with the system unproven.
That is why a top-up so rarely fixes it. The fluid is usually fine. What has actually gone is a sensor, a heater that failed on the first frost, an injector crystallised by short journeys, or a pump that cannot hold pressure. Each has its own fix and its own price, and you cannot tell them apart from the driver's seat.
Short journeys are the enemy of the whole system. AdBlue needs a hot exhaust to work and a hot exhaust to keep the injector clear. A diesel that does the school run and little else will see this warning sooner than one that does motorway miles.
Before you book an AdBlue delete
An AdBlue delete means the vehicle no longer meets the emissions standard it was approved to. Under regulation 61A of the Road Vehicles (Construction and Use) Regulations 1986 it is then an offence to use it on a public road, and it will not pass an MOT. A delete is for vehicles used off the public road, on private land, or being exported; driving to have the equipment repaired and driving to a port for export are both permitted.
By booking a delete you confirm the vehicle's use and accept our delete conditions, which are set out in full in our terms and conditions. That is the whole of the notice. You now have the facts, and the decision on what to do is yours to make.

AdBlue in Kent, the questions we get asked
How much does it cost in Kent?
A delete is from £245, one fixed figure from the registration, usually the same day you ask. A repair is quoted by JF Automotive in Maidstone once the car is on the ramp and the codes have been read, and agreed with you before any work starts.
I topped up and the light is still on. Why?
Because the lamp is reporting a stored fault, not the level. Topping up does not clear a fault, and on many cars the lamp only goes out after a successful self-check or once the fault is repaired and the code cleared. Treat it as a fault, not a fluid problem.
How quickly can you get to me in Kent?
Usually within a few days, sooner if the counter is low. Tell us the miles left when you enquire and we will prioritise it. We work Monday to Friday 8am to 5pm and Saturday 8am to 1pm.
Can the delete be reversed?
Yes. We keep your original file, and putting the car back exactly as it was takes one visit. Lease returns and dealer visits are the usual reasons. Tell us and we will book it in.
What if a main dealer software update wipes it?
We will need to visit again to reload the file, which carries a call-out charge starting at £50 depending on where in Kent you are. Tell the dealer the car has been modified before any update and they will usually leave the engine software alone.
Do you do AdBlue work outside Kent?
Remaps UK does, through the engineer for that area. East Sussex and London have their own pages; Essex and Surrey are covered from Kent for now and get their own pages as engineers are placed. Anywhere else, ask and we will tell you plainly whether we can reach you.
