The $225 offer is through BMW itself and meant to bring in older cars out of warranty, the local dealer can then offer to upsell on other services.

I just read the fine print (damn my eyesight!). The offer is good for cars 60 months or 60k miles old. Mine will be 60 months old toward the end of next year. So, it will work for me after one more oil change, at regular cost at the end of this year.

I see a lot of tires being replaced at less than 20k miles. Is that the norm, or should I insert an evil emoji laugh here

Also - do you guys replace all 4, or just the rears?

Just picked up my 6MT, and I extended the warranty from 4yrs/50k to 7yrs/75k miles bumper to bumper.

IMHO, a major factor is where you live. I am in south Florida where the tires are subjected to extremely hot temperatures and an unrelenting sun all year round. On average, I get about 12,000 miles or so based on my driving habits . If someone lives up north in a cooler climate they might get 20,000 miles on their PSS tires.

I usually replace the 2 fronts at the same time (when needed) and the same holds true for the rears.

I purchased a tire/ wheel/ PDR plan which cost me $2000 for 5 years. I have already replaced five 19" Michelin PSS tires due to nails and screws using this plan and in the black on this investment.

I’ve seen anywhere between 10k and 25k posted by others but I can’t imagine how they got 25k on these soft tires. I’ll be satisfied if I get 15k and very happy if I can coax 20k out of them.
As for replacement, you don’t have to do all four but, of course, at least in pairs (per axle) unless you have a damaged tire needing replaced and the other tire is very low mileage.

Fresh tires in the 19,000 range. Did all 4. Fronts not as warn as the rears but did not want a big difference in tread depth. Most driving is high speed on the interstate.

Just spent the coin to replace the Oil Filter Housing, heat mgmt module, and a few hoses. Originally noticed a low coolant error msg in ID7, followed by needing to refill the expansion tank, again, in 1-2 weeks. Then noticed leaking coolant (mixed with just enough oil to confuse me) on the garage floor. ~$2k labor, ~$1.4k parts from local non-dealer shop. Already had the water pump replaced (leaking was evident) 40k-ish miles ago.

Gotta love all that high quality plastic near the hot bits! Luckily, I wasn't left stranded anywhere, and this is a seemingly common issue (at least common enough to find countless youtube vids). Didn't want to tackle myself, though some of the vids did make it look easy-peasy.

2019. ~108k miles. Def not the first thing under the hood replaced, and I don't race it, lots of highway miles, baby it with every recommended service.

Dash, top, gas door, AC compressor and lines, door card, water pump, OFH and lines, broken spark plug ground (prob due to missing plug washer), engine mounts, and several electric gremlins sometimes solved with reboot / batt disconnect, non-working driver's door lock (key won't turn - plunger not moving). . . Almost as reliable as a--ok, let's focus on driving experience . . .it is a fun car!!

Wow, how much $$ out of pocket have you spent to maintain the car?

I start to waver on keeping anything long approaching 3k in repairs lol

Without searching transaction history or looking at the stack of receipts, I would estimate an easy $10k out of pocket, post warranty--Not counting oil changes, windshields, or tires.

[NytLyt]

I just had my engine replaced. I bought a 2020 CPO about 18 months ago with 19k on it. It was burning a quart of oil every 750 miles like clockwork. Every time the oil message popped up, I had to take it in for them to drain and measure the remaining oil to prove that it really was burning that much oil. After opening a case with BMW, the dealership was authorized to replace the engine. If I had waited 6 months to make my initial complaint, it would have been a $32k repair. My local dealership has a fantastic Service department, even though they have the typical slimy salesmen

From past experience with higher mileage BMW models, $10k for a car with 100k miles is not out of line. They have a lot of plastic components, gaskets and seals that don't withstand the heat. The good news is that once those parts have been fixed, the cars last another 100k miles or more without major issues.

I am surprised you got that many miles from the turbo. I have replaced them at 60k miles on average.

I have read a few peep talk about consuming oil . . . interesting to see that you got it taken care of, as others sounded like they were dismissed. I wouldn't presume that oil drinking is normal on a new car, so glad to hear of you getting it replaced. Any feedback expected on a post mortem? Curiosity and all . . .

Yeah, I was much more expecting the turbo to have an issue than I was expecting the AC compressor to poop itself awhile back. And thanks for jinxing me . . . Definitely entered ownership of my first BMW with complete expectation of this level of cost at this point in mileage (though would have preferred that it hit me a few months ago when still employed).

Your car was a relatively early production Z4. Fingers crossed that they engineered some of those issues out by the time my '22 was produced.

Once I noticed what I thought was a crazy amount of oil consumption, I found that BMW’s max allowable for the B58 is 1qt every 1k! That’s why they required the meticulous measurements before approving the engine swap. They had to perform a bunch of diagnostics to be certain there were no leaks or anything external first. BMW didn’t want them getting inside the engine as the risk was greater than the reward.

I have to assume that these get rebuilt and resold somewhere, but my service writer didn’t know. Our best guess is the original owner didn’t bother to follow break in procedures since he knew he was turning it in before the warranty expired and it would be someone else’s problem. I’m perfectly happy owning a 5 year old car with 25,000 miles and a brand new engine 😁

Let’s repeat that…..a replacement B58 is a $32k dollar repair!! That is like 45% of the cars value NEW. Very good that you kept on it and didn’t let it go.

Did they tell you what the problem was? I'm guessing valve guides.

No. BMW didn’t allow them to open the engine, just went straight to replacement. I doubt I’ll ever learn the cause. But I was very careful to follow the break in instructions with the new engine so hopefully this will last my lifetime. In 1 week, I was back at the dealership with 1,202 miles on the new engine for an oil change. This car has so much power that even keeping it under 4,500 RPM it is quicker than most cars. It was still a painful week 😂

We have all experienced the same pain and it is extremely difficult to resist the temptation of testing the true power of this engine in Sport Plus mode.

I personally almost slipped up at about 800 miles when I was showing off the car to one of my best friends and he asked me how powerful it was.

I'd honestly expect it to. It's a rare case, I'd think, with a B58 self destructing. A weird fluke or the previous owner actually somehow did something to it. They've been doing I6 ICE engines a very long time, and the B58 itself was out a few years before it ever made it into a G29 Z4.

I'm telling myself this anyhow, haha, as the owner of a new one.

[rikwynnpa]

My 2019 3.0 S drive spent zero time in the shop to fix stuff. Same for my 2025 M40. Build quality remarkable for a convertible.

I don’t see engine fires, transmissions needing replacement or any serious issues being reported . Thankfully things seem to be more random issues here and there.

The C8 is initially in a similar price range but those will be much more expensive to maintain as they age. I think we got it good folks
