Looking closer at the reliability data from CR, MY 2014 4-Series has a higher than average incidence of problems with fuel system, suspension/steering, paint/trim, body hardware, and power equipment. These contributed to the low reliability rating overall for 2014 4-Series. Drives: 2015 BMW 328i Xdrive Msport. Join Date: Oct 2018. Location: Cincinnati. iTrader: ( 0) DIY Custom Air Intake Project. Hey guys. I wanted to share with you a project that I did last month. I was slow to share because I wanted to put some miles on it (1000 in) to make sure no problems arose. But so far it's been great! Since purchasing my 335i I’ve put on 100,000 miles with the car having a total of over 115,000 miles at this stage. So far I’ve had the following major repairs under warranty with zero out of pocket cost: - Manual transmission replacement at 56,000 miles (common 2nd gear synchro issue) - OFHG and VCG gaskets replaced at 65,000 miles (both BMW 335i Sedan F30 - $20,795 A legit sports sedan, the F30 BMW 335i is a serious performance car with the N55 3.0-liter turbo inline-six engine that developed 302 hp and 300 lb-ft of twist. .

If the seller doesn't have a solid folder of receipts of work done professionally, avoid it. If it's $5k, it's that price for a damn reason. The problem is the other assembly called modulator and pump. I have only one car at the moment so I could not afford the downtime to research a repair. I purchased my unit from BMW of Minn for $940 which is the cheapest new part for this repair I could find. If you see my post on another members ABS post you will see the part numbers posted there. If you want to make sure that your BMW 335i has a long and trouble-free life, there are a few things you can do to ward off transmission problems. First, regular maintenance is key - make sure you get an oil change every 3,000-5,000 miles and have the transmission fluid changed once a year or after putting on 18,000 miles. Again, the G20 weighs in about 100-120 pounds lighter than the F30 when comparing similar models and options. Both cars maintain a roughly 50/50 weight distribution. However, the BMW G20 receives a 50% increase in body rigidity over the F30. All this leads to better handling for the G20 3-series. Thanks! I've driven another N55 for 100,000 miles with NO problems, just routine oil changes and that's it so I have faith in the N55s but I just don't know if this 335i has been tuned or had anything that could compromise long term reliability.
