Thank you B.M.W Ltd. The dealer just contacted me and offered to have it fixed at a mechanic close to me. Good on them! Hopefully they can diagnose it with no CEL!

Just bought a Newly imported 08 135i which has done 50,000km. Test drove perfectly. The day after getting home, the car cranked a lot before starting and ran like a dog for 1-2min then came right. The starting issue has been happening since (randomly), irrespective of the car being cold or hot. Now, today, 3 days after purchase, I'm driving along and go to pull away from a T intersection. The car shudders, has no power, and sounds absolutely terrible. I got out and recorded a video, which you'll find below. It sounds like it's not firing at all on one or two cylinders. Stopping the engine and re-starting fixed it. I have extensively read about these problems and it looks like the infamous injectors. The hard part is that the car isn't throwing any codes on the i-drive screen and no check engine light yet. Hmmm. Now, the dealer coincidentally texted me today saying he hoped the car is going well. I politely told him how the car was going and told him I'd email him a vid. Sent it to him and now we wait. I have a mechanical warranty but it would be mint if they stepped up and fixed it. Here's the vid! I'll update the thread as I hear. If you have had the same issues or have any suggestions on how to navigate it with the dealer, I'd be very grateful to hear from you.

I've done lots of research on these engines as I've just bought a freshly imported 08 135i last weekend that's done 50k . I'm having starting issues and the car will randomly stop firing on one or two cylinders. I'm about to make a thread about it. I hope that you can get it resolved but definitely get that checked under your warranty or CGA if it's not too late! Here's my video!

Welcome, I'll look out for you in on the M/way!

The thread you linked definitely sounds exactly like it. I'll go have a sniff. I don't think it'll be the battery, it cranks quite fast and the battery is brand new. I've read this thread extensively before buying: https://www.bmwn54tuners.com/8-most-common-bmw-n54-engine-problems/ . This guide also looks good: https://www.e90post.com/forums/showthread.php?t=651538 I wonder if we have the same problems with carbon in NZ with our different fuel/driving style. I've read direct injection means no difference but I haven't wrapped my head around whether that's correct or not. Thank you for taking the time to look all of this up for me. I really appreciate it!

But, that means I have to stop driving it and let it cool ?. Definitely a good idea. Will do. This dealer tried asking $900 for putting NZ maps on the car. When I refused and said don't do it (someone on TM offers it for $99. All it is, is a DVD!), they rang the next day and tried to say that it had already been done by mistake and demanded the money. I Just refused. Could be a fun experience moving forward based on that....

Thanks for your reply Tim. I shall take it up with them tomorrow. I feel like they'll just palm me off without a fault code or anything definitive but I"ll try! Yeah mate I can't wait! I've had two Mazda MPS's and they were awesome on the hill but not really a well built car. Got the honda as a sensible car and that was awesome but only lasted a year. 135 will be my first RWD so I'll ease into it slowly haha.

Hi all. Just bought a '08 135i ex-japan, and it's my first euro. It's done 50,000km. Traded from a K20 Euro R. I'm excited to finally have a well documented, well supported (at least by the consumer) vehicle with lots of information and DIY's available. I did lots of reading and took the punt on the N54, my reasoning being that I'm going to keep it stock. What I can't find is how we deal with the HPFP issue in NZ. The dealer must have had it warmed up for my test drive as after that and the long drive home from Auckland - you guessed it - it cranks for about 2-3sec before starting when cold and then idles rough until warm. Without bogging down my intro post, should I leave it until it codes? It won't lean-out or hurt itself in some way? I have 3 years of mechanical warranty but I have yet to read the policy so it could be useless. I'm aware that it could just be injectors, too, but I'd be keen to just drive it for a week and see if it settles down. Look forward to talking with you ? Stevo.
