I have just acquired a well-maintained 2007 A-Class Avant-garde (W169). The only deficiency is the absence of rear parking sensors, prompting me to consider my alternatives. May I get a pre-owned loom equipped with sensors?

Is it a straightforward installation with drilling where required and a simple plug-and-play process, or does it need additional steps?

Alternatively, one may choose an aftermarket alternative, which is less expensive but perhaps requires more effort.


I want no embellishments; the auditory signal suffices for my needs.

The Mercedes manufacturing system includes front and rear sensors, displays, control units, a main wire harness, a rear bumper harness, and a front bumper harness.
The eBay item is just a small component of the total, necessitating other purchases to ensure functionality, which will incur significant costs.


It is significantly advantageous to have a set of aftermarket sensors added. Flush mount options need bumper removal, making installation more complicated, although somewhat proud variants may allow for drilling without bumper removal, provided the correct locations are identified.

They also need painting to match your vehicle. If you are in proximity to Lightwater (M3 J3), see Alfie.

Excellent, it is just the kind of complication I want to avoid! I am not in proximity to the M3, but I am considering hiring someone to do the task for me, depending upon the cost.

Thank you

What is your location?

I am professionally engaged in this field, thus I can assist you if you are in proximity, or I can suggest a nearby technician.

Is the W169 equipped with pre-marked sensor drill holes beneath the bumper, similar to other brands?

I am uncertain if your vehicle is equipped with a Comand system that supports an integrated reverse camera. I just had a reversing camera and front parking sensors installed on my S204 by comand.co.uk, and I often regret not having them install rear sensors concurrently. In contrast, my SLK is equipped with front and rear sensors (along with Comand NTG2.5), but it lacks a reversing camera. The installation is cumbersome due to the boot wiring, however I want it anyway!

Thank you for your reply. My vehicle is a 2005 A150 with standard specifications. Attached is the audio located inside my vehicle.
