Yeah it sucks, but you can expect that with new cars, especially the first year of ownership. That is why it is better to wait until they get all the bugs worked out.

What’s very concerning is that the fuel pump can operate under spec pressure and not produce fault codes for BMW to diagnose. Therefore, your BMW can operate under spec with less performance and unless they get hard codes, and only then, will they perform a pressure test.

My e92 335i has had the pump replaced, and after it was replaced, it produced far more horse power than it did from early ownership. But fortunately, my DME produced fault codes which led to a pressure test. But now the car feels as if it is not producing the horse power it once was. But BMW won’t do a pressure test, because there are no recorded faults.

Makes you wonder how many 335i’s out there that are running below performance spec and the owners are unaware of it. And soon, it’ll be M3 owners.

There should be a class action suit against BMW for this and they should buy my car back as well as many others who are scared to come forward and make a formal complaint. It is hard for people who have been a BMW fan and owner most of their lives to complain so outwardly. My e92 335i has been nothing but trouble since day one.

A perfect example of one problem I had with the car was it losing power on highway 101 in the fast lane (warning light alerted me of an engine malfunction and loss of power) and I almost got rear-ended by four cars because I could hardly get off the highway. Scared the hell out of me and it was the first time I actually thought I was going to die. If this ever happens while my wife is driving the car I will absolutely submit a formal complaint - God forbid this ever happens to someone who has kids in the car and something serious happens.

My experience with the local BMW dealership service department is awful. The cars are lovely, but there is something v e r y wrong with the BMW dealerships.

The problem could be lack of competition, we have just one BMW Center here in San Antonio. I have a 2011 M3 sedan, what is the classification, E-93?

2008 M3 convertible w/18k miles. About a year ago I went out to the car and the keyless entry didn't work. Opened the door manually and when I started it an error message saying set date and time came up. Check control had a message "Increased battery discharge" took the car to he dealer who couldn't figure out so BMW had them replace the instrument cluster. Now in the last few weeks every so often I"ll go out, the keyless unlock wont work and I immediately get the set time message (but not date) and increased battery discharge. After I reset the time I have to shut the car off and restart it clear the check control message. Haven't seen any posts like this and wonder if I have a gremlin in there that won't go away.

My 2008 E92 M3 DCT w/ 29,000 miles just started having the same problem with the "Increased battery discharge" warning, and requiring a clock reset every time I start the car. Also keyless unlock seems flaky. I have an appointment next week to take the car in.

I have a feeling it is a combination of a battery that is gettign ready to fail, and that I only drive the car every two or three days which doesn't allow this weak battery to charge suffienctly.

I'm having similar experiences with the BMW Center here in San Antonio. My experiences with Mercedes dealerships was always top notch.
