Dougnzl 0 Report post Posted November 24, 2016 Hi I am really keen to get a 135i , looking for a 2009-2010 model so would be N54 engine. I have read some stories online about HPFP , water pump and walnut blasting ! What are the things to look out for ? What are peoples experiences of this cars reliability? Would it be best to go for a 2010 Model? Any info would be appreciated, I really want one of these but dont want a dog! Thanks Quote Share this post Link to post Share on other sites
3 SERIES 93 Report post Posted November 24, 2016 Great cars, alot of fun but proceed with these steps. 1/ Get a Pre Purchase inspection done by a reputable BMW workshop 2/ Cut a deal with the seller. 3/ Buy an Autosure warranty 4/ Be prepared for the water pump to go.

*Glenn* 854 Report post Posted November 24, 2016 The only people I would recommend to do the PPI and servicing on these N54 twin tubo'd vehicles is BM Workshop Botany (2716636) or Grey Lynn (3761236) 1 Quote Share this post Link to post Share on other sites

Matth5 471 Report post Posted November 24, 2016 I'd suggest an N55 if you find one within your budget. They seem more reliable. Get a warranty if you can, Autosure has already made a loss on me after a water pump leak was found and my stock chargepipe exploded! Quote Share this post Link to post Share on other sites

Stevie S 49 Report post Posted November 24, 2016 (edited) If you wish to tune you will get more power from the N54. turbos/Wastegates Oil Filter housing Leak Waterpump abs pump purchase warranty for sure, I bleed autosure dry Edited November 24, 2016 by mattone74 Quote Share this post Link to post Share on other sites

With the money you save on maintenance/repairs, you can probably get an upgraded turbo for the N55 which will turn the tables MHD is out for the N55 now so they can now be tuned just as easily too Edited November 25, 2016 by Matth5 Quote Share this post Link to post Share on other sites
Herbmiester 925 Report post Posted November 27, 2016 The N54 motors seem reliable just the parts bolted to them are the issue. Quote Share this post Link to post Share on other sites
