Replace or keep? A case study of a 2007 335i with 140K miles
Hi everyone! My apologies for the long post… but I’ve got a tricky question, and this may be a helpful case study for others in similar positions.
I have a 2007 E90 335i with about 140,000 miles on it. Important: currently it’s our secondary car, so I only use it for three 12-mile round trips a week… so ~3,000 miles a year conservatively. Recently a few more major issues are starting to pop up:
Aside from these, the car is running great and certainly enough for my ~36 miles of driving per week! It’s brought me a lot of joy over the years but now I don’t push it much at all to avoid more problems. The big question is: replace or keep? Here’s how I see the math -- would love your advice! --- REPLACE Trade-In Value: Let’s optimistically say $5,000 (KBB says probably $2,400!) Replacement Car: $10,000 (it still won’t be nearly as nice as what I have now, but I want something that’s not too old so I don’t get sucked into MORE repairs… this includes tax + fees) Transaction Net $: -$5,000 And then there will be service/repairs required, probably a few thousand each year, plus small depreciation and increased insurance. --- KEEP Repairs needed: $3,000 for computer fix (apparently this is a tricky one that only dealers can do, my shop said… ?), $2,000 for transmission fix, $1,000 for bushing replacements Transaction Net $:-$6,000 And probably a few thousand each year in other repairs… who knows what will break next? Basically zero depreciation at this point. But I am left with a loaded 2007 BMW 335i! --- BOTTOM LINE I just looked through the used car listings, and they look totally depressing… Makes me lean hard toward just repairing my car and using it lightly. I guess the most mature thing would be to get a very cheap used car like a Corolla or Accent with ~75,000 miles on it… Our other car is a Hyundai Ioniq Plug-In Hybrid Limited, and it's actually very peppy (torque basically equal to the 335i gear-for-gear due to very aggressive gearing)... electric cars are surprisingly fun, and the Limited trim has an outstanding sound system, quite a bit better than the 2007 335i's upgraded HK system (which has huge gaps in mid-range sound that I never realized). Curious what you all think! I figure some of you have navigated this same question… Thank you for your time and thoughts! Last edited by Drivaar; 03-02-2020 at 12:59 AM.. |

Where is the oil leak coming from? Unless its a oil pan, it shouldnt cost too much to fix.
temps creeping up to 250F is "normal" for a BMW with the electric water pump. do u have any codes related to the alt failure? i don't see any problems, but again, wouldnt cost 2 grand to fix. All you need to do with the transmission is drop the pan, replace it, inspect the valve body (rebuild or replace if necessary) and replace whichever shift solenoid is causing the code (6>5) or just replace all of them. Any transmission shop will do. There's probably more to your suspension causing play, such as control arms/ball joints. Again, unless you're rebuilding your entire front suspension shouldnt cost $1000. If the rest of the car is in good shape, I'd say its a good bet to keep it. Just find any good mechanic to take a look at your car. Doesn't need to be BMW specific. |

It sounds like you don't DIY much or at all. If you plan on keeping the car either learn how to DIY or find a good/ great mechanic that specializes in European Automotive, who won't charge you an arm & a leg & is HONEST.
If you can't do either, then sell it and take your losses. |

I don't think a 335 w/ an n54 motor is for the feint at heart. There's no oil leak on an n54 that can't be fixed. The mechanics the car has been taken to are a bunch of quacks.
The OP needs a car with the n52 motor or a Honda Accord. One of the two |

Replacing the DME is something that can be DIY'd with the right software. You can do it with ISTA/P. Personally I'd first try sending it out to a DME repair company and see if they can do all the software cloning or board repairs for you. If a shop is saying a dealer should do it, it's because they probably don't have the right software or have techs with the experience for it.

140k isn’t high miles it’s shameful the car has all those problems. Sounds like someone neglected it. The car is fiscally to far gone. You answered your own question, I guess you want affirmation. Cut your losses, and I don’t know who would give 5k for it, no one in their right mind. You probably got more in parts that the car as a whole.

It sounds like it's too far gone and not a good investment to fix. You most likely would be lucky to get $2500 for it, I would move on to a N52.

Since it's a car you don't drive enough to even warm up why bother with a turbo'ed I6 you can't enjoy? The corolla would suit that situation better as an occasional commuter, or even better a plugin that you wouldn't need to even gas up.

Thanks everyone for your comments! A few responses:
e90yyc: thank you for the support! Oil Leak: two well-rated shops have improved it but failed to fix it fully. So I've been on the "monthly top up + scheduled oil change" plan for the last 3 years... 250F Temps: with the oil cooler (which I have installed), the car should run around 220F and get to 240F in the worst stop-and-go (like an hour of inching). 250F is high but I agree, not terrible... Transmission: thanks Moisture for the tips. The shop I had asked didn't seem to think it was this easy, but I'll ask another shop about this. Finding a Good Shop: I'd love any recommendations re: good shops/mechanics in the San Francisco East Bay area. I'm not always happy with their work, but I'm not sure what I can do beyond finding the best shops via Yelp + Google. I can't DIY for multiple reasons, though I enjoy fixing other simpler things around the house... so I need to find a good shop or independent mechanic. Steering Play: Cool, yeah hopefully it's not too bad. I was just being conservative with the estimate. Things ALWAYS end up being more expensive than people on the forums thing... the Bay Area is very very expensive also for labor rates. DME: Great advice, thanks Cyrix2k and Welcome to NBA Jam (great name!) Sell or Keep: Part of why I started this thread is because the idea of "it'll cost more to repair it than it's worth" is not the right metric to decide whether to keep a car, even though it's said a lot... Because getting a replacement actually costs quite a bit, and then you have to account for the replacement's depreciation and repairs. FWIW, I do still get enjoyment from it every time I drive this car, even for short distances. Thanks again everyone! Last edited by Drivaar; 03-03-2020 at 12:55 AM.. |

Dont know too many bmw shops in the Bay area since I diyed most of the things on my n51 e90. However, on top of my head I can name 2 shops I went to to fix some stuff on my b8 s4 (don't shame me, that pile is nothing like e90 and a nightmare to work on yourself). So one shop was Nelco German auto in Sunnyvale, while def not the least expensive, Zach is very good at keeping you in the loop and honest. He def works on BMW's. Another shop I've been to is called The Shop in San Bruno, they are less expensive and more generic but not always do things right the first time, but generally will make it right. You can also ask people around in the regional forum.
Definitely try to send out your dme to get fixed. Afaik Vehicular DIY had a video on YouTube how to do it or described how he got his cloned. You also might want to start watching his videos since you got an n54 e90. |

I would move on.. You will own many cars, no need to waste your time and money with a trouble maker.. The BMW I have found is for someone that likes to continue to work on cars. So if you want to keep fixing said car than keep but it will be never ending... Or just move on to an Asia car and be happy..
