How concerned are you about the biturbo's reliability?
I know this has been discussed to death, but I'm curious about how the lingering biturbo quality concerns will affect people's decision to purchase a 135i.
As for me, it still seems like BMW hasn't finished that last 1% of engineering work on the biturbo motor. The overheating issues on the 335i seem to have been temporarily resolved, but how do you miss an issue like that? I will still probably buy a 135i, largely on the strength of BMW's warranty, but part of me thinks the 128i -- with its bulletproof NA engine -- might be the more satisfying long termer. |

I'm not too concerned about overheating.....
I'm more concerned about an engine that runs such high temps under normal conditions.

The way I view it, since I am normally very into modding, I think this is the better path for me regardless of reliability. I have no real plans of any modications to my 135i, which means I have no worries in regards to paying for problems that come down the road because I will have the factory warranty. With that being said, I still expect a certain standard of quality to come from the factory and will not put up with constant issues arising. In any case, my mind is completely set on the 135i until I hear/read otherwise.

I don't expect to buy soon, perhaps in a couiple of year,so I haven't completely settled on a 135i but it's very tempting especially in convertible form. I think keeping my options open is wise at this point.

LoL at this post, I'm aware of the previous 335i issues, but look at it this way, they got to drive free loaners while they were figuring out the problem. I'll drive someone elses car for free for a month or two, I dont care if its a base 328i, thats 1-2k miles NOT going on my car...

Now that they will all come with an oil cooler and a dip-stick, I'm not worried about the few problems that have been reported.
I have no worries about the turbos themselves. They are just too damn small and light to ever create the forces that cause big, heavy turbos to frag into pieces. And coking the oil in the turbo after shutdown without cool-down time after extreme driving is a human error, not an engine flaw. I control that. The only extra problems I foresee with the turbos would be vacuum leaks. Every turbo engine owner from any car maker is familiar enough with vacuum leaks that they all know how to spell "vacuum leak" correctly... Taking the turbos out of the equation, it simply is another 3 liter high output BMW engine like any of it's NA counterparts. I wouldn't be any more worried about the rest of the engine handling 300 hp/ 300 torque than any other NA BMW engine putting out the same hp/torque. Last edited by Nixon; 08-10-2009 at 03:23 PM.. |

Oil cooler is with the sport pkg; not standard. & the 335 has no dip stick, where did you see that 135 does?

In the UK brochure they mentioned a dipstick on the 135i - BUT, I'm afraid that piece of info was jumbled up with info on one of the diesel engined variants (another typo). * SIGH *

I hope it has a dipstick also. I wouldn't bet on it though. ; -)
BTW, the second link also shows diesel features - common rail injection, variable vane turbos. |

I'm just saying that looking at the 135i engine from the perspective of output per liter, it won't be as stressed as the engine I already have (per liter). Since the 135i will have a lower output per liter than the car I currently own, I personally am less worried about engine problems in the 135i than in my current car. I'm not putting bragging rights out there on my current car. I'm not dogging the 135i for it's output per liter. I'm just explaining my perspective of running a higher output per liter engine and not having problems. The only thing the chip has to do with it is that it takes the chip to get my engine to that level of output. There is no problem to solve. I'm not trying to get into a pissing contest about what engine is better than the other. Does that make sense? |
