From dashboard warnings on the school run in Sevenoaks to a countdown timer stopping a commercial van in Loughton, these are the faults we see week in, week out across the region.
A dashboard warning can stem from fluid level, sensor failure or dosing faults. We confirm the exact cause before recommending any work.
Once the countdown reaches zero the engine won't restart. We clear the underlying fault, not just the warning.
If the dosing pump can't reach the SCR system properly, it often triggers a wider fault cascade.
A faulty sensor sends the wrong reading to the ECU, triggering warnings even when the reductant system itself is fine.
Cold, damp winters across the South East are a common cause of crystallised AdBlue blocking the injector.
If the tank heater fails, the fluid can freeze in cold weather, stopping the system from dosing correctly.
