This customer was glad they returned their X5 back to us for an MOT, intake swirl flap removal & DPF Forte Power Clean.
During a service a few months ago. We upload the service history from the BMW Database into the vehicles I-Drive. At the same time we always check the vehicle fault codes free of charge during the service and report to the customer if recommended attention is required.
On this occasion we noticed engine fault codes for swirl flap movement & DPF high back pressure. The Diesel N47 engine in this model is prone to the intake swirl flaps becoming stiff in movement from carbon build up or worse wearing on the shaft causing them to fall off going into the engine combustion cylinders. Causing large expensive damage writing off the engine and in some cases the vehicle!
As a result of engine fault codes stored being present. It can prevent the engine ecu from regenerating the DPF – Diesel Particulate Filter of its own accord, causing it to block over time.
So we recommended on their next visit we check/ remove the intake swirl flaps and carry out a Forte DPF Power Clean, the most cost effective method to clean/ repair your a DPF.
As you can see from the pictures, the customer was very lucky. Cylinder 2 swirl flap had fallen off completely and luckily was too large to pass the intake valves and was sat in the intake port. Cylinder 4 was ready to fall off with the other two loose!
So we removed all swirl flaps, rod & blanked the rod hole with a bung. Along with manually removing as much carbon build up as possible.
For regular maintenance we recommend the Forte Intake System Power Clean which would soften & break down this carbon build up on the engine intake manifold and valves.
Once rebuilt we carried out the Forte DPF Power Clean to bring the exhaust back pressure levels low, well within spec so it will now regenerate of its own accord once again.
So you can see the benefits of using a Specalist Garage with experience, expertise & equipment to maintain your BMW & MINI with cost effective solutions!
