nice!

Now that I've read the blueprint of the N54 and the N55 as well, I'm pondering whether I should trade my N54 for its successor

Anyways very educational post. Thanks Ksfrogman

I got the Dinan tune (there was only one at that time, 400hp and 400 #/ft) when the car was about 4-6 months old. The car has the factory oil cooler and has been through all the factory recommended and mandatory updates for the HPFP problems. Only one of the reflashes wiped out the Dinan tune, and I had that re-installed for the cost of 45 min. labor for a Stage II tune.

The bottom line is that this is the greatest car ever made! I have NEVER kept a car for more than 2-3 years, and this one is 5 years old. I'm starting to get the new car itch, but other than a very few minor things, there is nothing out there better, and I will probably keep it.

My experience says: "If you're thinkiing of keeping your N54 beyond 30-40K, do it. If you're thinking of buying used, do it. Don't worry about the OLD bad rep."

YMMV

+1 2007 msport and still happy. Want to buy or tinker but aside from hud what the hell is there better?

So I want buy this 07 335i, it's just at 100,001 carfax is clean. Just 2 recall issues. Air bag and blower fan Motor wire. Everyone is saying I shouldn't. Ive read about it through a bunch of threads. It's only going to be driven 4 months outta the year. The previous owners only averaged about 26,000 a year, what should I be looking out for if I "jump" on this sale?

Williamdalton01 · 01-21-2019, 08:35 PM

This is awesome! Learned so much about my car haha!
