Hi guys I'm George from Greece, I own a 2009 530i Xdrive with the N53B30 engine.
I got the car in 2012 and I don't want to sell it yet, so I decided to retrofit bumpers and skirts from the MPacket model that I found used. The firment went well and the car is a beauty but I have an issue with the PDC ever since! MPack bumpers use different parking sensors to the SE.
the front bumper arrived with the sensors on and used them but on the rear I didn't have the proper sensors so the guy that did the swap went a little creative and managed to fit the sensors from the SE bumper to the MPack.

My question is are the Mpack sensors work my SE car?
I have issues with the front sensors. I replaced one that seemed faulty but now all including the one i fit seem not to work and the 9E3B code appeared as well.

Now I plan on removing the front bumper to check the harness and go from there.
After than I plan on replacing the PDC module..

What do you guys think?

check the harness, I had similar issue once I did msport bumper swap, some connection was loose. hopefully that is your problem

Yea that's what I'm thinking too.
I'll take the bumper off to check that.
I'm worried that the pdc module is gone.. i can't find any if those in Greece and I'll have to order it on-line.
Online order can taje up to a month to arrive.

I know the sensors are a different size between LCI (18mm) and Pre-LCI (20mm). I did not, however know that there was a difference between msport and the basic bumper cover.

Unfortunately yea.
different size... M sport are thicker, didn't measure them tho.
Today there was an update, took the front bumper out and tried the stock front sensors.. Boom they worked fine no issues no warnings nothing!
So we modded the m pack bumper to accept the stock SE sensors and that's the end.
Works like it used to..
Now I learned I need a M Pack crash bar! I will make the front bumper sit better !
