Zeee 0 Report post Posted December 20, 2022 I have a few questions about the e82 135i, specifically the N54 version What are some of the most common problems with the car What are some key upgrades to make in terms of performance and reliability to when the car is driven hard And there is no doubt it will be driven hard! Are they expensive or hard to do maintenance on yourself Are they still alright with over 150,000km on the clock Quote Share this post Link to post Share on other sites
charles28 136 Report post Posted December 21, 2022 Hi, There are some common issues. They are at an age where if you're lucky, most have been remedied. ie HPFP, Injectors, various oil leaks (OHHG, VCG etc) However waterpumps have a tendency to just fail without warning and sometimes don't last many K's The N55 engine has the same water pump issues too. Mines been ok and i'm pushing about 600hp, but maybe i'm just lucky. I would strongly recommend a pre-purchase inspection from a Euro car specialist (not the dealer) Quote Share this post Link to post Share on other sites
