Recent Mini Cooper Petrol recovered to us

Symptoms of engine light on and engine cutting out at idle. Car had already been ‘quickly plugged in elsewhere’ with Camshaft Sensor faults.

Carried out short road test, engine light on with poor low idle. Vehicle diagnostic test showed no camshaft sensor faults but Vanos actuator movement on inlet & exhaust (the last place we’re close I guess ?‍♂️). If you don’t know what Vanos is and would like to know more please read this – https://en.m.wikipedia.org/wiki/VANOS

First step on these is to check oil is present in the engine. Near maximum on this as customer knows of the high oil consumption on these engines and tops up regularly, so that’s not the cause.

Next removed both Vanos Solenoid valves to check the strainers fitted to them for soiling, and hey presto nearly blocked solid. Restricting the oil flow to Vanos Camshaft Hubs which move from oil flow/ pressure.

Cleaned both strainers, refitted and carried out engine vanos adaptation test. Both values nearly bang in the middle, which is a good sign of healthy vanos solenoids, camshaft hubs and timing chain. Cleared all faults.

Road tested vehicle from cold to hot twice (once following day). Now driving as it should with no faults stored.
Nice simple known fault rectified within one hour of our investigation price of only £49 inc vat. With no parts needing replacement.
More times than not it’s cheaper to take your pride and joy to the people who know what they’re doing first time round! If you’re having troubles… you know who to call ?

Swirl Flap Removal & on Car DPF Cleaning

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!
