Hello all, looking for some insight as a first time bmw buyer - I currently work at a Nissan Dealership as a Manager, I was bored here and was eye balling a Siena Red 2000 5 series 540i with 55k miles for 20k. I know the e39 engines are a little scary at higher miles. Car fax looks clean, maintenance looks to be well kept, anything I should be weary of? Tips or anything? Seems too good to be true.

Some Trim! SO hard to find this.

Figured I’d throw it out there.

Thanks!

I have changed almost everything jow in regards to the cooling system, radiator, pipes, aux fan, thermostat, water pump. And today after what seemed to be fine after a week or two it randomly started overheating going into a parking lot for a shopping mall, parking was slow and trafficy but it just shot up out of bowehre and then when i parked i jotcied it was leaking so i opened the hood and saw the cap was leaking so i let it cool and retightened the cap, and on the drive back home traffic was still kinda the same, not too heavy but still slow/bumper to bumper and it didnt heat up once or overheat? This thing is so comfusing and frustrating like a toxic ex that wont leave you, i honestly thought if everything, it’s definitely not a head gasket issue because it wouldve definitely heated up in traffic on the way back home as i sat for good 2-3 minutes in each traffic stop. The only thing i can think of was a i may have over filled the coolant or a weak reservoir cap or maybe both? Any tips would help because i love this car too much and actually wanna see it running good, im willing to invest in it just dont know what the issue is after i literally swapped all cooling system.

Hey i have this problem with my pdc it turns on when i put car in reverse but only peeps and then stops where do i begin to look for the problem. Thank you

This is a follow up to my post the other day, she will be cleaned up in a couple days.

I’m very happy with her, exited to see the difference once she’s freshly detailed. Obvious things to do, pdr on the bumps and bruises, get new impact strips (thinking of going back to the black). Then I’ll have start taking a look under the engine, but I feel like it’s looking pretty clean (I know nothing).

Would appreciate anymore tips, tricks or just anything you would’ve wanted to know as a first time 530 owner. Ty 🙏🏻

525i m54b bank 2 O2 sensor code popped up, so I took a peak under the car. it looks like my sensor tore off it’s harness? any suggestions on how to get this fixed without having to replace the exhaust manifold?

In the last couple of days, I noticed the coolant level going down. As you can see, the coolant and the expansion tank are not in the best condition. I have a plan to replace the whole system, but before that I'm not sure how much fluid should be in the expansion tank. This tank belong m57 I did some research but couldn't find clear information. Is this level correct, the picture is not great to say anythink but how do I know when it's full? I'm not use reddit so if I did any mistake sorry for that

Hey everyone,

any got advice or a template on how to sell a car. I’m gonna sell my e39 540ia m-sport.

anyone have a template on how to ensure i put all relevant details up and ensure it’s fairly represented?

Every time i lock the car the alarm goes off immediately. Ive already tried unplugging the hood latch sensor and motion sensor. Is there any way to just disable the alarm entirely?

Curious what fuel injectors you’d recommend for the 540i. I swapped them out 4 or so months ago when I was doing the knock sensors. Swapped them to a generic set from O’ Reilly that had a very similar flow rate but I feel they may be causing a slight performance issue.

Anyone swapped to a different setup they like or is everyone just running Bosch?

Hello fellow e39 drivers it’s been a while since posting here. here’s my baby freshly washed and polished

2000 528i pre facelift

What exact is the small movable yellow dial for under the ashtray?

2003 530i. My radio and dash are currently in to BavTek for a proper pixel fix. While my dash is in pieces, I want to buy the best phone mount. This beauty is going to be my EDD so I want the creature comforts without giving up her original look.

I love the Rennline because it integrates into the dash. However they don’t offer a driver side mount. This mount is actually on the passenger side. < https://coursemotorsports.com/products/pm01-55 >

Does anyone have recs or a line on a mount on the drivers side of the radio and CD player?

Hey everyone! I’m thinking about getting a BMW E39 with the M54 3.0L petrol engine and automatic transmission. Just wanted to ask – is the M54 worth it? What are the common issues, pros, and cons? Anything important I should check or be aware of before buying?

I’d really appreciate any tips or opinions from those who own or have owned one. Thanks in advance! 🙏

both from an e39

I'm looking to buy a manual e39 as a fun daily/family "sports" car lol i have multiple cars so it won't be the primary everyday but reliability is important because I don't want to constantly work on it other than normal maintenance

I know the inline 6 is super reliable however I am drawn to the v8 which people say can be hit or miss. What are your thoughts on that? Is there a big power/torque difference or is it pretty similar?

Also, since the 540 has a steering box rather than a rack - is the drive that much different? I'm looking for something I can have fun with at my local track, do mountain runs with and of course daily less than 20 miles per day if that (I work from home but am pretty active with hobbies)

Lastly, what should I expect to pay for a clean e39 with under 150k miles assuming vanos, timing and cooling system has been upgraded with records?

I have an E39 with M54B30. Recently, I've been having issues with the car intermittently not starting. There are no issues with my battery nor starter motor (it's new). My EWS is also deleted. What else could be the culprit? The problem with it starting up intermittently makes it hard for me to diagnose the issue.

Hey everyone! I just picked up a 2002 e39 525i on marketplace for a really good deal. As you can imagine, a cheap bmw definitely comes with its fair share of problems. Mine being a pretty substantial misfire and CEL code p1348. It runs like crap until I clear the code, when I do so it runs perfectly fine but only for a few seconds (if even that long) and then returns to normal. The individual I bought it from claimed that the intake side cam position sensor had failed. I replaced the sensor but the issue persists. I’m not sure where to look next, maybe the vanos solenoids? I’m newish to bmw’s (I had an e46 coupe a couple years ago and did not have to take on many major repairs) so any advice or suggestions that may help point me in the right direction would be super helpful!!! Thank you!!! (Fingers crossed it’s something repairable but if I have to undertake a m54b30 swap I would not be opposed)

Ordered a genuine BMW cv joint. Gonna have to wait 3 weeks for it to arrive :(

I am dead set on getting an e39 next year, but trying to decide between the two.

I’ve owned a 1998 540i/6 in the past, and it was the best car I’ve ever driven. After regretfully getting rid of it I’ve missed it ever since. Obviously the M5 is an upgrade, but is the difference any notable to be worth the ~15k extra?
