Hi folks,

after owning my e92 for just past a year now with no end of problems i think i have finally got down to what the main problem as advised by a BMW specialist looks like the timing chain is stretched and slipping causing the injectors to over compensate pushing too much petrol into the engine causing un burnt petrol to mix with my oil wich in turn is throwing up faults all over the place as the oil is so thin, what im really needing to find out is how often should the timing chain be changed on the 320i E92?
