BMW E39 M5 Rear Bumper Replacement DIY

[@iiineon13]

Has anyone found out the part numbers of the screws and acceptors for the diffuser ? Help is much appreciated. I can’t find them nowhere

[@E39Source]

You can use 51118174185 where the diffuser meets the bumper at the bottom. For the sides, you'll need small self-tapping screws. The factory ones were a 7mm head. BMW never published the part numbers for this hardware, so I usually go through my spare fasteners until I find parts that fit if the original ones were missing.

[@garytanaka]

Looks like you're building yourself a brand new e39 M5! Can't wait until you replace the engine and trans!

[@Tha_Zhuk]

That's what I was just thinking about as I saw this video, is he going to replace the whole drivetrain too?!

[@davidjackson7168]

Sounds about right I'd rebuild it as well fellas and just supercharge it. He's doing right by the tho if you own the best car ever made you'd be willing to do the work to keep it str8.

[@garytanaka]

Resources not being an obstacle, I would happily rebuild my 2000 M5 or even my 2001 540i-6spd - if I still had them. Sigh....

[@davidjackson7168]

Love the videos fellas e39 m5 best car hands down. Have learned a lot more from following you guys...my M car soon to come. I'll keep everyone posted its gonna be crazy Mississippi style.

[@WindlePoones]

HI Ryan, how do you get the diffuser to detach from the slotted holes in the bumper? The clips on my diffuser don't want to let go?

[@lucrativestance]

Just curious those 9 rivets you mentioned that connect the rear bumper cover to the metal bar, are they the same ones that are in the rear fender liner? The 3 on each side? I can't seem to verify it on real oem.

[@E39Source]

Yes they are, the ones that end in -185

[@lucrativestance]

@@E39Source thank you I appreciate the response, I need to replace all of mine, I busted them when I was removing them haha

[@jerryaowen]

This vid saved my day! My two middle sensors stopped working and that meant bumper removal. The very last of the 5 series had a plastic trim in the centre of the bumper as well and not just the corners which mine has which clearly means BMW knew the difficulty of rear inner PDC removal. My M5's radio / cd has stopped working, the fuses are ok and the sat nav works any ideas? Many thanks.

[@E39Source]

Happy to help! So no FM/AM or CD? Sounds like the radio module. I recommend you upgrade to a BM53 radio. I have a video that involves adding the BM53 radio and BMW SIRIUS XM to my 2000 M5, please reference that!

[@jerryaowen]

Hi Thanks for the advice I will check out your video, tomorrow.

[@GETaYOTA]

That rust at 10:45. Don't you just love that?! Got it on mine too but worse. Always wondered if you had it there or not

[@E39Source]

I've been chasing little bubbles around that car for two years. That's set to be fixed as well as the final jack point this fall. It'll be another $1,000 ish, but then I'll be mostly rust free.

[@stephenmckeown4867]

hi ryan i bought a 97 540i m5 rep last week. The back bumper needs re painted so i will be removing it shortly. When you put the car into reverse there is a bleep noise but there is no pdc button above the cup holders. Is this a poor retrofit? or is it factory. I say poor because it does not always engage so i cannot rely on it!

[@josereal4200]

What are the two metal poles on the bumper? (he was calling them bumper stunts )

[@E39Source]

Those are bumper struts* that would help absorb an impact if you get hit from behind.

[@josereal4200]

E39Source, LLC do you think I can buy a single strut or do I have to buy the whole rear bumper.....I’m asking because my dad drilled a hole (idk why he did that ) in a strut and liquid squirted out ,and I dont know what will happen if I connect the battery and try starting the car, please let me know

[@E39Source]

@@josereal4200 You could probably get away with replacing just a strut if the bumper and carrier is still in good condition. The car won't know that there is a hole in the strut, but that can absolutely be a safety hazard in the event of an accident. I would just replace that strut.

[@josereal4200]

E39Source, LLC I also need help with my 2003 530i (e39). It does not want to charge , I already checked EVERY fuse ,replaced the battery, and got a new alternator, and I also literally checked all of the wires and there was no shorts. My only option right now is to register the new battery that I got because I never registered it. Or to relocate a new ground. Please let me know cause I want to get this car running ASAP

[@E39Source]

@@josereal4200 That is very bizarre. Something must be wrong, a fuse in the wrong spot, one missing, etc. Or a bad ground. I don't know of anything else that could cause this.

[@PursuitMode2011]

Ryan where is the acoustical keyless chirp chirp siren speaker located on a 2002 E39 540i? My keyless entry chirp sound is really low. Wanted to clean it or inspect it.

[@E39Source]

That speaker is located behind the rear right fender liner.

[@brianmiles7796]

Great video, many thanks, I'm thinking of putting parking sencers on my 1998 5 series, is it a 1 man job?

[@HankePanke]

Did you do it?

[@salehbyatra4707]

its the same as for all E39 series

[@benm6899]

Hi do you have a part number for the new boot trim ?

[@E39Source]

Do you mean the trunk opening trim on the chassis just inside the trunk lid? That would be this: tinyurl.com/3my4a6h9

[@benm6899]

@@E39Source yes that’s the one, thank you 😀

[@MILKJUGSISPRO]

I've got about a quarter inch gap between the top of my bumper and the bottom of the trunk, do you know how to adjust that at all?

[@E39Source]

The guides need to be severely adjusted, open up the fender liners and move it around!

[@JAMAEL89]

Great job. Helped me get it done with no fear. Thank you.

[@UncleTags]

Perfect, just what I needed this afternoon. Clear and precise and to the point, thanks for sharing - top man ;)

[@admiralfloofz658]

Is this similar to a 528 rear bumper? Need to remove mine to mount a towhook

[@E39Source]

Kristoffer Lilja Very similar process, this should get you through it no problem.

[@timminss]

My car didn't come with PDC, but I have been offered a bumper and rear PDC system. Would my car have the holes in the metal through which I would feed the sensor cables? Awesome channel by the way - have subscribed :)

[@E39Source]

You only need holes for the front sensors, the rear metal bumper doesn't need any holes. Your car's front metal bumper won't have the holes from factory, but you could affordably find one online that does have the holes and swap them if you want the front sensors too.

[@timminss]

E39Source thanks a lot for the response!

[@JulzWinfield]

Another perfect video. Thanks fellas!!

[@shawnschroer5665]

Where did you get your bumper cover, cost and was it pre-painted? Thanks!

[@E39Source]

Primed, painted by a local shop here.

[@necrostalker]

Hey Ryan! Im looking at RealOEM and I cant find the "Defuser"(?) anywhere among the parts. Could you help me locate it? :)

[@E39Source]

+Sebastian Gunnarsson Rear diffuser part number is 51122693662.

[@necrostalker]

Great. Thanks for The help! Like all the vids here :) Keep up the good workshop!

[@necrostalker]

[@selfmadetrey7756]

How much can I get both m5 bumpers for and where the best place ?

[@E39Source]

+selfmade trey If you are in the US, for OEM bumpers, ECS Tuning or The BMW Mini Parts Store is the best. Outside of the US I am not sure, you'd have to research.

[@christophersousa6109]

Do you have a link for the jack stands you used or ones you recommend?

[@E39Source]

I just use Harbor Freight 6 ton axle stands.

[@christophersousa6109]

Thank you so much!

[@bobm5ful]

Are you selling the old bumper? mine has a crack

[@E39Source]

Mine was cracked as well, but I did already sell it.

[@gabemartinez1012]

You still have the stock suspension on it?

[@E39Source]

Yup, all in great shape too. I'll never touch that, BMW M knows best.

[@chaldoboy1000]

Hey there You think I can upgrade my 02 530i with M conversion bumper ?

[@E39Source]

You certainly can, if you can justify the cost the time. The rear bumper is much easier though, as you won't have the change the air ducts, belly pan, fender liners, etc.

[@chaldoboy1000]

E39Source so for my understanding all I need is buy an M rear bumper with re use my old bumper support came on my non sport bumper & snap it in ??

[@E39Source]

You'll need the lower diffuser as well, but I think the guides should work with the M bumper. So it would just slide on the rear and bolt in.

[@chaldoboy1000]

E39Source what would you recommend buying it from ? A good replica quality bumper PP ?

[@E39Source]

I don't recommend replica parts. They're by definition fake knock-offs. However, if an OE part is not in the budget, I would go with an Umnitza.

[@wheatonna]

Reinstalling those six plastic rivets in the fender well is nearly impossible, at my house.

[@ahmetorhan05]

What was wrong with the old bumper it looks same.

[@E39Source]

Never see on camera. Paint and clear coat are totally screwed on the old bumper, as well as a crack. Condition just brought the whole care down.

[@ahmetorhan05]

thanks for the reply. I Always watch your uploads and love your car.We own a bmw E39 523i Executive.

[@E39Source]

ahmet orhan Thanks so much! Feel free to make some videos of your car any time, I know our viewers would love to see it. :)

[@bobm5ful]

How much was the oem bumper

[@E39Source]

Just the bumper is around $550. Add in the trim, diffuser, mounts, some hardware, and the painting, and it's around $1250.

[@berkeleydojah]

replacing that because of "scuffs"? wow

[@billdenler6480]

Very well done!

[@JPrandy1]

nice plates man.

[@roniuitto3223]

Thanks for the video, that help a lot! Let's see how i'll be doing by myself. :D
