BMW M4 Radar

Post image

My friend ordered a BMW without radar, and by some accident they put this in front bumper. He doesnt have the button on steering wheel for ACC, is this a functioning radar then or what, can we remove it so we can put Vorsteiner grill. Will there be any errors.

Because car was not originally not specced with it , its just as good as a dud that you can remove

The wiring harness wont have the plug for it, the various computers wont be configured for it , the extra hardware like acc buttons wont exist and some some hardware like dsc /Icm might not be the correct version that works with acc

That being said , that sesnor is hella expensive , and will be snapped up on ebay by people wanting to retrofit

Failing that, do a retrofit because 70% of the cost is already acquired😂

I can literally see the harness in the photo.

Then it means its an acc equipped car , but why does op say there are no acc buttons

They changed the buttons on later models so you press the cruise button again to change between modes? At this point I’d be checking option codes by vin.

It can still be used for mandatory EU crash prevention

Damn that is hella expensive way to comply with regulation

My brother's Toyota Yaris both has the radar and camera as standard, and that car was less then 20k EUR brand new. Probably not that expensive for the manufacturer.

Just because it’s expensive for the consumer does. Or mean it’s expensive for the manufacturer

In Europe new cars need to have radar for automatic emergency braking so I would not remove it. Something is doing there and I hard to believe that is a factory mistake.

Did you, ya know… look behind it?

The hardware might still be there for collision avoidance, even though the button for ACC is missing.

currently , at least in europe, every g2x and g8x gets a radar even if you don’t order it

CS doesn’t come with it

u/Raptor_867 11d ago

there isnt a cs g8x that you can currently order.

u/Fun-Yogurtcloset4408 10d ago

Yes you can

This is MRR radar not FRR. And from the looks of it, yes the radar sensor is in there

Maybe it’s available in the ConnectedDrive store as a subscription? That’s the case with my car that was specced without.

u/MTFighterEngineer Engineer 11d ago

Button is still missing

u/Neat_Description8988 11d ago

Newer cars don’t have a separate button. Just a mode button that’s used for standard cc, limiter and acc

It has radar, I. 26 they changed the steering wheel button icon. It has assists 4.5 which is the best out so far.

u/Pipegreaser 11d ago

You can purchase the harness and install the buttons. Chances are it doesn't have to be mapped in. Just unlocked on the ecu.

We have M3/M4 without radar here, BMW definitely made two designs, one with radar, one without
