Could be a bad voltage regulator. They do funky things sometimes.
BMW parts reviews
For whats its worth, I had mine replaced at Safelite and haven't had any issues 4 months later. They used Pilkington glass which is OEM for BMW. HUD still works great. ACC did need recalibration the next day (City Safety features turned off) but they were able to do it at Safelite with Bosch equipment. I use Pilot Assist for >50% of my driving and it is functioning the same as before.
Used Zimmerman rotors with Akebono pads
I’ve replaced them alone (i’m not a tech, i am not even a beginner).
NGK plugs, 60 euros bought online, some tools i already owned, and I struggled with the spark plug socket, found it at a tech friend, the thing is that is necessary to be thin and i needed to borrowed a torque wrench. Half an hour of work.
I use a bottle of RedEx every few tanks in my 2015 320d, which is on about 90k. It seems to have increased my fuel economy by about 5%, tested by doing the same 200 mile route many times.
I would stick to Bosch, Mann & Mahle for filters.
Those are very good EBC pads, they also don’t destroy rotors. I will warn you that a brake bedding is absolutely critical with those. They very much rely on the transfer layer for better stopping performance and to not destroy your rotors. Thankfully, usually within 2 to 3 laps they have enough heat in them that you’re able to get a good transfer layer going.
Few months ago I got all 6 OBD1 Bosch coil packs and it changed nothing for me other than a slightly smoother top end, I still have a slight misfire at idle.
I had all new Bosch coils installed on my e46 M3 about 30k miles ago. They worked fine, until one day the car went into limp mode due to bad coil / misfire.
I had a pair of depo headlights, maybe the same ones there. They started with good light output and relatively quickly degraded on the low beam with the projector. I got a chance to drive that car again and they are pretty terrible now, warning.
