Hi,

My E class is throwing an error for the FCW. It's been in for diagnostics at an Indie and apparently the radar unit in the bumper is kaput!

I was hoping to fix this myself however the guys at the garage mention it'll need coding in. Is this the case or can I swap out the old unit for the new one?

I believe the part number is A0009058406
 
There is a control unit on the drivers side inside the bumper, then a 1 meter white strip that looks like hot-gluegun glue with a purple sensor at the end of it.

Should be easily replaced if you know which part is at fault. Not sure about coding though.

Thanks for the reply. I've found a few options for the radar unit it's just the coding that's the issue. Asking around seems to be a split of people who think it needs coding in, some that don't and some that don't know!
