Dension DIY installation has lead to PDC acting weird

Hi guys

I would really appreciate any advice on this, also I have just joined the forum and I hope I am in the correct section

I own a BMW 630i 2005 with the M-ASK single slot idrive 6.5 and with a CDC
I remove the CDC to install the Dension 500sBT system
I had a play around with the Dip switch settings on the device in order to make it work with my car

However after doing so, I noticed when I put the car into reverse that the PDC, parking distance control is acting irractically and the rear sensor is a continuos beep.
I don't know if the dension installation has something to do with it or it is just a coincendence and that one of the sensor has failed.

I feel pretty dishearted as I just got my car and really would love to know what the solution is to
1. Fix the PDC
2. Install the dension
3. Can it be fixed ? And would a software update help?

I really appreciate any advice given and I would be very humbled.

Thanks

Greg

I would try re-posting in the main 6 series section located here. This is the DIY (do it yourself) section and it does not get many views.

A few people have installed the Dension so they might have some advice.

The PDC control unit is a separate module so I don't think that is the issue. Maybe try pulling the connections to the sensors and re-connecting them one at a time to see if you can identify a bad sensor.

Thanks yorgi , I'll do that
