Gianni682 Posted 7 hours ago Share Posted 7 hours ago Greetings, all! If it made sense, I'd stretch to a 50d, but I'm also considering the 30d (which I could remap for additional power), the 40d, and the F15 X5. Focusing on used cars with acceptable mileage and history are within my budget of £15,000 to £26,000. A couple of particular enquiries: How are the handling and performance in actual driving situations different? Is the 40d/50d's twin-turbo system significantly faster at low RPMs than a remapped 30d, for instance, in terms of throttle response and torque? Is the more complicated 40d/50d configurations less reliable than a chipped/remapped 30d in the long run, or is it the other way around? Have you noticed any typical problems? I've heard that the 40d is more refined than a tuned 30d, but I'm looking for real-world owner insights if anyone has any... In ahead, I'm really grateful.

KOOLCAR Posted 7 hours ago Share Posted 7 hours ago Because the higher-powered twin or triple turbo models seem to ruin bottom ends more than the lower-powered single-turbo variants, I would recommend going with the 30d. Repairs cost an absurd amount of money, yet the N57 is becoming increasingly famous for it. Quote Link to comment Share on other sites More sharing options...
MidnightMarauder Posted 7 hours ago Share Posted 7 hours ago Doesn't the B58 come in a petrol variant as well? Quote Link to comment Share on other sites More sharing options...

xsports Posted 7 hours ago Share Posted 7 hours ago Yeah, I'm aware they have an x3 and an x5, and I'd be surprised if there was much of a difference in fuel efficiency between the two. Quote Link to comment Share on other sites More sharing options...
Gianni682 Posted 7 hours ago Author Share Posted 7 hours ago On Autotrader, there's a Japanese import 335i that looks really good. I'm assuming it won't have the diesel's low-down torque and, based on what I've read, will be far thirstier. I see now that you've confirmed my suspicions; a single turbo seems like the best option. The m-performance package is my top choice, but I'll settle for one with harmon kardon, a pan roof, a good or full history, and reasonable mileage. Those third-row seats aren't for me, but they're removable and most people have them. There is a beautiful one that meets all my requirements; however, it is a 40d with 90k. I believe the harmon kardon is an absolute must-have, but I'm sure we'll have to make some sacrifices somewhere. After all, installing the kit looks like a lot less of a chore than replacing the sound system! Quote Link to comment Share on other sites More sharing options...

MidnightMarauder Posted 7 hours ago Share Posted 7 hours ago Diesel engines produce more torque, while petrol engines are slightly more thirsty. When diesel engines are warmed up and going on extended cruises, they become more efficient. Modern turbocharged petrol, on the other hand, isn't terrible for daily use and has far more torque than older NA petrol. With the exception of daily caravan pulling, the B58 torque should be more than enough for most applications. In my opinion, driving a diesel with a high mileage is not going to be easy. They are fantastic if you return them after three years of leasing. Good luck Quote Link to comment Share on other sites More sharing options...
