Hi all, I've noticed in the last few months what seemed like a tiny issue that suddenly got a lot worse last night. A few months ago I noticed that the engine while idling or while holding a fairly slow speed, particularly while still warming up, the revs would rise very slightly for a few seconds, then drop back again for a seconds then repeat until the car was at normal operating temperature when the issue seemed to go away - it would only rise a small amount say from 1200 to 1220 rpm, just enough to notice a pitch change in the sound of the engine. However last night while driving home after a 4k trip to grab groceries, I noticed that the revving issue was now affecting the car at full temperature, and the difference in revs was much greater, roughly 1200 rpm to 1400 or 1500 rpm - by the time I got home I noticed that the headlight and tail light brightness would rise and fall with the engine revs. I turned the car off and let it sit for a couple of hours, then turned it on and let the engine idle, which it did without any rise and fall in revs - I'll take it for a drive around the neighbourhood tonight and see if the rise/fall thing starts happening again. Has anyone experienced a fault such as that before? I wondered if the alternator or some electrical system was malfunctioning but the battery is quite new and still has plenty of kick to turn over the N62. TIA for any helpful hints and advice, Chris W, Chch

Hi, I have a 2007 e92 coupe 335i, warning lights have all popped up one straight after the other along with my window wipers going automatically on their own with no way of turning them off. All buttons on the steering wheel won't respond and window wiper thingy doesn't work. Indicators manually have to be turned off after turning a 45° angle. The warning lights showing are Tyre Pressure / stop start technology / traction control. I'll attach a picture of the icons showing. I've replaced the battery and also coded it. BM place calibrated the steering wheel but it on clear and popped up again. When I turn car off and leave it for a couple of hours and turn it on it seems fine then 30mins I to a trip everything pops up again. Greatful for any advice if anyone has had these issues. Thanks
