Car is out of warranty. I have a 2019 M240. Pretty sure a tail light needs to be replaced. I've read that the M235's need to be coded but from that's when they upgrade them. If I just get a replacement tail light from the dealer for my car does it have to be programed by them too?

Tail light needs replacement, or just a bulb/lamp is out?

Have you checked the bulbs and fuses? Simple process and I'm sure will avoid unnecessary stealership charges. My experience is with Canbus systems, the fast switching is a signal that the circuit has an issue and is usual the resistance measured meaning a lamp is not there or failed.

Try the simple fixes first!

Tail light is just a housing that holds lamps in place. So there's the lamps, the circuit, or the fuse protecting it. The circuit being compromised is not such a common issue, nor is a fuse blowing on a simple circuit. Is possible, just not so common. Tail light HOUSING would need replacement if it's cracked, or possibly leaking, water entry causing the other noted issues. And that's rare too on a vehicle not so old.

Again, try the bulbs and if not, check fuses...

Good Luck!

There are several long threads about this problem on these forums. 235s had a problem with the ground connections in the housing being inadequate and overheating. 240s have a different problem which may or may not even be fixed by replacing the taillight.

Been a little bit since I've been on here. Sorry for the late response. Yes I had the fast blinker for a long while now and it was pretty consistent. Since it wasn't a daily driver I didn't really have to deal with it often.

Anyway, I posted on a facebook page and most felt since I was just going to replace the tail light and wasn't upgrading like the 235's did I could just go plug and play.

Also for what it's worth for the future someone said his was doing the same thing. All he did was remove it and put it back together (most likely the connector) and his was all good. I did this a couple weekends ago and moved around the harness itself since it was kind of bent goofy. I thought back to the Impreza's I used to work on for their front turn signal with their harness getting kinked. Anyway all good now. I haven't had one fast blink In numerous long drives.

Hi , i have a 2018 M240 with 45K miles on it, so not on warranty. I had intermittent rear tail light malfunction message initially. But it has become more often now. Also my rear right tail light is blinking fast. Any options to fix this issue without spending a fortune with BMW dealership?
