⚠️ DPF issues usually have an underlying cause.
🔍 We focus on the underlying cause when performing our analysis of what is happening with a vehicle.
🛻 Here we have a BMW X1 where the DPF light came on recently.
❗ The owner was originally enquiring about a DPF Clean, but as we found this would have been unnecessary as the DPF was NOT blocked.
⚠️ A DPF Clean is unnecessary and not recommended unless you have a blocked DPF.
🎯 The underlying cause with this one was a failed glow plug.
⚠️ Before regeneration will be attempted the vehicle needs to be warm enough (short journeys or old thermostats are an issue) and also enough fuel (approx ¼ tank minimum). Other components are then checked and BMWs like these NEED the glow plug system fully functional.
❗ A good tip for a diesel vehicle with a DPF is ALWAYS keep the fuel levels above ¼ tank.
