BMW E46 models use a plastic bumper cover over a rigid strut-supported aluminum bumper. This cover is painted to match your vehicle. It is frequently scratched and damaged. The bumper cover can be replaced quite easily. You can replace a bumper cover with a factory part, or an aftermarket one if you want to upgrade the look of your E46. Remember to plan to have it painted before you install it, so leave yourself extra time.

In this article, I will go over the steps involved with removing the front bumper cover. Removing it is required to service the A/C condenser, headlight assembly, horns, and headlight washers. The headlight washers may be the biggest concern behind the bumper as they frequently leak. 

Keep in mind that when your car was serviced before, parts may have been replaced with different size fasteners used in the replacement. The sizes of the nuts and bolts we give may be different from what you have, so be prepared with different size sockets and wrenches. 

Protect your eyes, hands and body from fluids, dust and debris while working on your vehicle. If you are working with the electrical system, disconnect the battery before beginning. Always catch fluids in appropriate containers and properly dispose of any fluid waste. Recycle parts, packaging and fluids when possible. Never work on your vehicle if you feel the task is beyond your ability. 

Our vehicle may vary slightly from yours as models do change and evolve, as they grow older. If something seems different, let us know and share your info to help other users. Do you have questions or want to add to the article? Leave a comment below. When leaving a comment, please leave your vehicle information.

Raise the front of your vehicle and support it safely using jack stands. See our Pelican Parts technical article on Jacking Up Your BMW. 
Start working at the left and right lower corners of the bumper.

To install the front bumper, start by partially installing the bumper while leaving enough space to access electrical connectors and hoses. Reconnect the disconnected items. Slide the bumper cover onto the bumper supports and torque the bumper bolts to specs as shown. Install the lower bumper screws and reattach the wheel well liner to the bumper. Install the fog light / bumper trim in reverse of removal and check the bumper alignment with the body to make sure everything is flush.

If bumper height adjustment is needed, you can raise or lower bumper by turning the height adjuster in bumper support.

Dags Comments: Hello
wonder if you can assist. I have a BMW E46. At some stage the front bumper cover must have hit a speed bump or load road etc..
So other that the normal scratches, the point at which this cover attaches to the front right wing has unattached and assume there is a bracket or hanger at this point that secures this part of the bumper cover to the wing. Could you let me know what this part is and the best way of replacing it.

many thanks
best Regards

AlecO Comments: I have an '01 convertible 330ci. The front bumper is sagging on passenger's side, and I was wondering what the problem might be. I'll attach pics.
July 26, 2017
  Followup from the Pelican Staff: The bumper has become detached from the mounts. Either they are broken or it simply was forced off. - Nick at Pelican Parts  
Legendblob Comments: In line with April's problem, I had minor work done on my 2006 M3 convertible. Dent on drivers side fender. Body shop had to remove the bumper to fix the fender. Got the car back and a couple miles down the road I got Check Engine Soon yellow light. I later got it checked with code reader at AutoZone P0070 Ambient temperature sensor which is located in the front bumper. Temperature reading is still accurate. Body shop said they checked it out and everything is connected. My question is can this sensor trigger the Check Engine Soon warning?
April 14, 2017
  Followup from the Pelican Staff: Ambient sensor should not trigger a check engine light, but may store a code. I would suggest repairing the sensor / testing it. Then clearing fault and seeing if it returns. - Nick at Pelican Parts  
Kevin S. Comments: Fasteners used to attach bumper cover to carrier are BMW 51118222901, Blind Compression Rivet, 6x21mm. You'll need a POM Riveting tool to install them.

Kevin S. Comments: Front bumper cover fell off wife's car. Investigation revealed it had been removed and reinstalled improperly at some point before we bought it. I purchased a new cover and hardware and have two questions I'm unable to find an answer to: What hardware is used to fasten the bumper cover to the carrier All of these connectors were broken or missing but appear to be some type of plastic rivet and what hardware is used to attach the bottom of the cover to the splash guard - if any? There are holes in the splash guard that line up with holes in the bumper cover, but I don't see any diagrams at RealOEM that show any fasteners for that purpose.

  Followup from the Pelican Staff: What type of car are you working on? Could be an expansion rivet or plastic rivet. - Nick at Pelican Parts  
T. Comments: I am hoping there is a trim repair kit that would include necessary bolts, clips, stabilizers for reattaching the front bumper trim. We drove up on a parking curb and tore the front bumper trim cover off of the aluminum bumper frame. I believe the previous owner had not attached it correctly. I don't have any clips or bolts remaining to put it back on and I'm not sure what was there to start with so I can replace it. Any suggestions?
Thank you in advance.

Mdcarrier05 Comments: Great article, I have a 2006 M3 that I would like to remove the bumper cover and have it repainted. After looking at this mine is different and does not have the holes for the torx screws to be removed. It is the front fascia that an M3 has along with the air ducts in the front.
Can you help with installation instructions
January 24, 2016
  Followup from the Pelican Staff: We don't currently have that tech article. If we get a chance to perform the procedure, we will be sure to document it.

I would grab a repair manual. It will have the procedure, special tools and torque specs.

April Comments: I had it checked. Only ambient air sensor code
July 25, 2015
  Followup from the Pelican Staff: Fix the sensor, then check power, ground and data to the cluster. - Nick at Pelican Parts  
April Comments: and started walking away and the sunroof decided to close. With no key.
This cannot be caused by the dash cluster so I am glad I didn’t let the mechanics fix it yet. The car never had issues before, now it has gremlins. Now it shuts off on me while I am driving. EML / Oil / Brake / etc lights come on, the whole car starts shaking and slowing down then shuts off. When I start it up sometimes it starts very rough. Shaking and the RPMs are highly unsteady. I have to turn it off and back on until it starts correctly.
I cannot lock or unlock the doors with the console button. Only manually with the key. When I lock the doors with the key – the emergency flashers go off. That’s the only time the emergency flashers work.

  Followup from the Pelican Staff: I responded under the other questions. The fault codes are going to be the key here, you either have a module fault or cluster failing. - Nick at Pelican Parts  
April Comments: I am sorry I do not see a relevant article to post this on.
I need help.

I desperately need advice. I have a 2005 BMW 325i auto. It has 88k on it. I have had the vehicle over two years and have never really had any serious problems with it, until now. The ambient air sensor was ripped out and the plastic under the car that it hooks into was damaged fairly badly. –it’s a long story. I believe this started all of my problems. I am planning to replace the ambient air sensor but before I do I would like some advice from anyone that has possibly seen the same problems in their vehicles.
I have had the ambient air sensor replaced before, but it didn’t cause the same problems. I am not mechanically inclined. I know some, but not too much. I do not want to be taken advantage of at a mechanic shop over it. I am wondering if the sensor was pulled out hard enough to cause electrical problems?
So here we go.. The ambient air sensor and plastic was ripped up. The sensor is dragging on the ground. The A/C went out. I know this is due to the sensor registering a below freezing temperature and not allowing the A/C to come on.
About a week afterwards the dash cluster completely goes out. I did not know how fast I was going, how much gas I had or how many miles I had on the car. You cannot see or hear the turn signals. I checked all of the fuses and disconnected the battery for 30 minutes. Nothing worked. The battery was at 12. Right where it needed to be.
I drove like this for two days and took it to a local mechanic that specializes in BMW. They had the car for two days. They reset the computer by disconnecting the battery. Didn't work for them either. They told me that the Dash cluster was out. They said they could get one with 115K on it but it couldn't be reprogrammed. My car has quite a few less miles so I went and picked up my car and just drove it until I did a little research.
A couple of days later most of the dash cluster started working again. Mileage, speedometer, tach, gas gauge.. but the back lights do not illuminate and in the dark it’s difficult to see how fast you are going. Turn signals still do not illuminate and you cannot hear them. When half of the cluster started working again – more issues came up. All of the buttons on my steering wheel stopped working, and the sunroof became stuck open. – Randomly – a couple of days later it was raining so I was going to leave my car in someone’s garage – I took the key out – locked the door and started walk

  Followup from the Pelican Staff: These sensors are damaged all the time, and I have never seen them cause other components to fail.

I would start by checking the vehicle for fault codes. If multiple systems are not working properly, fault codes will be set. This will be your best bet when diagnosing.
