Front Bumper damage - Can it be repaired or needs replacement?

Hi all,

First time posting in the forum. Became a BMW 435d owner recently after quite a long wait. (2015 model year, bought second hand; not under any dealership warranty)

This morning, to my surprise, I noticed a crack near the hinge of the front bumper on the left side of my car. I have no idea how this was caused as it's definitely not an accident; there aren't any hit marks either. My main suspicion is that this could have happened by a large pothole given my commute is riddled with them.

So the main question is whether this is repairable without replacing the bumper (i.e. at a bodyshop) or will i need to replace it?

Furthermore, is this something I can live with for some time or is there potential for the crack to worsen?

Appreciate all the info/feedback I can get.

It looks like it has been pulled and as itís fixed at that point has ripped. Doubt going over potholes would have done that. Do your tyres rub? Or have you ever grounded the front bumper? Have a look at the front under the bumper lip?

It also looks like it doesnít fit too well. Iíd be tempted to take the entire bumper off, take a look at it and then refit. As to repairing it, Iíve no idea.

Thanks for the info. Does indeed seem as a pull but haven't had any such incident. Tyres don't rub.

Fitment of the bumper was fine; had the car detailed a couple of months ago and made sure everything looked pristine.

As for under the bumper, I have a carbon fiber front lip. I did scrape it once or twice while getting into my parking spot in my apartment complex (it's on a steep incline) and have a few scratches underneath (expected) but other than that no case where I would suspect this to be caused. That was also weeks ago. This crack appeared within the last couple of days. My mind went to potholes as they're the only road "mishap" I've had recently.

I'll be taking the car to a local bodyshop I trust in a week or two. They've been serving both my family's cars and the rental company my dad works at for years now and does an amazing job. I believe they can repair the bumper, but in any case, I would like to see the opinion here.

Yes, most likely it can be repaired.

However, I'd want to know what caused it before repairing.

Have you owned the car since new?

Wow... you really didn't remember what you did. That is a pull, I have the same damage on my S14 Silvia lowered backing up on parking spot and bumper got stuck on the concrete block. If it was a pot hole it should have more damage the other way around.

No; Got it second-hand 5 months ago. From what the other guys are saying sounds like a pull

Thanks. I understand what you're saying. If it looks and smells like a pull, it probably is.

I'll need to check with the guys that operate the car washing service for my firm. The firm basically offers this service where you can leave keys at the reception, have the pickup the car from our parking area, take it down the road to their (hand) car wash place and return it washed during the day. Though like washing it myself, I occasionally have it done at work; and did so a week ago.

Was trying to recall the places my car had been in the past couple of weeks trying to figure out the root cause and this is a 2-3 hour window where it was elsewhere without me in it.

It "can" be repaired with a plastic/nitrogen welder. Most good collision shops have them. However, it depends on your expectations. If you want it perfect get a new one. If you're trying to be cost effective, then repair it.

Thanks!

Given the body shop I use has done a great job in the past for me/family on several occasions, and thus know what to expect, I'll probably go with the repair route.

Can you check for any signs of previous front end work? Bolts that look like they have been screwed/unscrewed, anything different from left side to right one in paint quality outside and inside the engine bay, etc. I would suspect previous damage that was not properly mended and cracked again

I'd also go for repair....not for cost, but to keep the better quality paint work.

Ive had several bumpers replaced and painted, none of them seem to hold up to rock chips of daily driving like OEM paint does. Different shops, one was PPG paint shop too.
(Yah yah yah I need PPF installed, I know lol)

Checked and nothing suspicious. Also had a thorough check before purchasing it and all was in near mint condition. Previous owner had it well looked after (he upgraded to an M3)

Thanks for the advice. Indeed it seems to be holding up quite well considering the amount of rocks (especially from lorries) and other debris in my daily commute
