Default Front Sensor Repair

Yesterday while driving home, a piece of rubber bounced up and perfectly hit my left front parking sensor to pop it out. The dealership wants $450 to fix it, and they recommended a body shop to do it as their hourly rate is less. The body shop was also $450.

I have a few tools and can do some stuff, but definitely not a mechanic. Is taking the front bumper off and fixing this something that a novice can do? Or do it just bite the bullet?

Look into cheaper replacement parts from VW or Audi. Could be same/similar parts for less money? Sorry for your troubles.

No parts are needed. My dealership checked it out for me and there is no damage to the sensor. It's just the freakin' labor cost.

There are at least two good YouTube videos on this. Just search YouTube for "porsche 991 front bumper removal". You can do it... two sets of hands is helpful.

Thanks for that. i watched one and it looks like I could get the bumper off, but putting it back on could be a problem. One viewer had that issue. There is one clip that is removed at the end that looks like a total bear to take off.

Also, the videos are for 991.1 and wonder what needs to be done with the active vents on the 991.2.

My understanding is the headlight removal is slightly different and there's an additional wiring connector for the vents. Believe you can see it on the Rennline video.

Hardest part of removal for me was the daytime running light connector. (Push the wheelwell towards the tire from the headlight housing). Worst part of reassembly was the headlights. (Minor). I did the r&r by myself.

Oops, sorry... I should have noticed that beautiful 991.2 in your avatar. In case it helps, I remember seeing this post from Detailed Designs a while back. Headlight removal IS apparently different like Homeles said, but it sounds like you wouldn't have to since this thread is saying you have to drop the bumper to remove the headlights. Here's that thread if it is helpful:

Same thing happened to me (except right front sensor), something on freeway knocked the sensor back into the front bumper. You could look thru the empty hole and see it hanging by it's wires inside the bumper. I was able to reach in-between the air inlet slats in front of the radiator just enough to grab the sensor and push it from behind back into the it's original position.

Okay, I am going to try that later today - let's see! Thanks so much.

Given that there isn't a video of removing the front bumper assembly I have opted not to try it. I went to a good service station, too, Exxon great falls and he told me it would be at least three hours for them to do it as the shop manuals aren't out.

So, this weekend I unscrewed the bottom of the front clip to try to get my hand in behind the bumper with no luck. I also tried sticking my arm up through a hole in the bottom, again with no luck.

I was actually thinking about using a dent puller but not sure about removing the hot glue after pulling it back into place. I looked on-line for a strong mini suction cup but didn't find anything. I have until Thursday to find a solution as then when it is scheduled for the dealership.

I don't have a pic, but it is just the front parking sensor was pushed into and behind the front bumper. I can see it and could probably attach something to it but not sure if it would have enough grip to pull it forward.

I have removed from front bumper cover. I don't think that you will be able to re-seat it without removing the front bumper cover. It is very easy to remove the front bumper, straight forward, no surprises. The only issue is that is takes some time to do so, especially when its the first time. That's the bad news. The good news is once the bumper is removed, you can install the Rennline grills and protect your radiators for essentially the cost of the part as the bumper cover removal labor is already absorbed. The removal should take no longer than an 1.25 hrs. Putting in back together takes about 40 min.
Good luck.
