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 ?
