Actually the internal 2nd gear ratio was about 1.6 - similar to 3rd on an E90. And the curb weight was around 3,600 pounds.

But I guess it still had decent compression!

Nobody said anything about you being uneducated.

Drumroll and cymbals please. bSorry, you set yourself up for that one.

I can't wait to see what the OP says/does when the new car does the same thing in 2nd gear.

Just picked up the new car. Funny how it doesn't roll like the other one did.
I spoke to the tech and he seems to think that the compression loss was caused by a faulty ring on one of the pistons. He also said he saw signs that the engine was starved of oil. Not sure why the previous owner would do that to the car, specially with the free maintance plan. IDK maybe it was an oil delivery pump problem. Oh well, now I have a different car with a few less miles and nice tan interior (which I wanted)

LOL you ever notice those defensive posts where someone says they are an engineer, have been "published," yet are claiming that you get worse performance with 93 octane than 91 octane fuel? Sometimes people are "too" educated to use common sense.

That tech should stick to doing his job, i.e. changing oil, cleaning brake pads, vacuuming the interior and remembering to cover the seats and put the paper mat down with the blue footprints. What he seems to think means little, he isn't paid to think.

Tech's are not paid to think? Seriously? Come on, you could have come up with something better then that couldn't you? Since you directed that comment to "techs" in general I take offensive to that.

[Philm35]

Not to harp on the OP, but many years ago, I had a '78 VW Scirocco. One day, I left it in a parking space on a slight slope, in 1st gear, but absentmindedly didn't use the parking brake. Sometime later, the transmission popped out of gear, the car rolled backwards and hit two other cars. The parking brake is your friend. Belt and suspenders.

On my way to the BMW dealership today the car threw a check engine light AKA a "fault code" any guesses on what it was????? Please take a guess! Misfire on multiple cylinders and lost of compression on multiple cylinders. The car now has a new home at BMW and I will be trading this lemon in for another 2007 they have available, luckily I was still under the "return for any reason 30 policy".

The techs are working on it tomorrow to find out the actual problem is (but I could really care less as I am not dealing with this thing ever again) I will post updates if they reach out to tell me what went on.

For those of you that were helpful, thank you!

For those of you that provided ridicule after the request not to provide ridicule, go F*** yourself!

I'm usually not one to bother posting much, but how does the fact that your car had a misfire on multiple cylinders relate to your original posting about your car rolling when you don't pull the hand brake?

Someone pointed out that their strategy is to finish a job as quickly as possible when compared to the book rate. The dealerships gain this way. As in life, the people who are held accountable are those who have skin in the game. A tech has none.

When a customer brings say a 335 in for stalling, the dealership has it for a day, and it stalls on the way out as the customer is driving home, does the customer look for the tech who worked on the vehicle that day? Of course not, he's not accountable. He only does what he's told by his foreman, SA, service manager. He has no authority to say this is the problem, that is the problem, yes, no, or maybe the work will be performed.

Not all shops are ran this way. This also has nothing to do with a tech not being paid to think. You only talking about "dealerships"(where those techs also get paid to think). There are a lot of independent shops where the tech's deal directly with the customer and takes on a lot of responsibility of their repairs and their relationship with the customer.

this is the reason why M cars arent real M cars anymore.

people that dont know a thing about cars feel like they should know how a car is supposed to work and if enough dumb people complain bmw gets shit for it. use first or reverse and stfo

[jopa489]

Interesting thread, I guess. I leave my cars in gear without the e-brake sometimes, like if it's in the garage on a completely flat surface. Never had a problem, but I use the e-brake when parking elsewhere.

[jsweiss]

Looks like I have found this thread a year after it's death. I ended up here by searching for a reason that my 330xi rolls backward when parked in 3rd or 5th gear. (not 1st). It happens a sluggish millimeter or two at a time, then a chug of an inch or two. My driveway is on a slight incline. Although I have not encountered this problem before in life, the problem now makes senses ... regarding engine compression and weight. Now that I think about this even more, this is how a manual car can be started by pushing it. This is not a problem with the car itself and I will now be a fan of the e-brake.

[krhodes1]

Note that if the rolling in gear causes the engine to turn backwards, bad things can happen to the timing chain and tensioners. I don't know if this is an issue with BMWs or not, but why take the chance? You KNOW BMW will sieze upon this as an excuse to not warranty an issue, given half a chance.

Even in first or reverse, engine compression WILL bleed past the rings eventually, and the car WILL move if parked on a steep enough grade. Particularly on modern cars running synthetic lubricants. And the smaller the engine and the heavier the car, the more likely it is to happen. My '08 Saab 9-3 would roll on a grade in first! Same wieght as my 328i Touring, but only a 2.0l engine.

In other words, use the parking brake. That is what it is there for.

[ShakyDog]

From the owners manual, page:

Manual transmission
1. With the car at a standstill, briefly press the
start/stop button.
2. Shift into first gear or reverse.
3. Apply the parking brake.

Autos have park so they can get away with no e-brake, a heavy car can't - ESP with AWD you have twice as many traction points trying to turn the drive train and thus the engine. Low compression doesn't help either...[/QUOTE]

"Park" on an auto box simply locks the transmission, it is n ot a substitute for the hand brake, E brake, call it what you will,it is the same as leaving a manual transmission box in gear, as so many people have said previously, Basic driver training says whenever you stop "apply the hand brake" this is what it is for, it is an esential security device, provided for the sole pourpose of keeping the vehicle static.

Use it or live with the cosequences, because you live in the most litigious society on the planet.

In the manual, for automatic vehicles it states to use the parking brake when on an incline, to relieve stress on the transmission.

But, from other manual cars over the years I agree with you all, depending on the way you are facing you use either R or 1st.

[Billt335]

1st gear and parking brake. Don't feel bad mine back into a light pole and it feel into a neighbors yard! Learned a lesson on that one!

[Majikthese42]

I've always used reverse since it's the lowest gear ratio. (With the parking brake.)

[fallintotherhyme]

My e92 yesterday rolled on no grade from neutral....scary thing is it rolled a fucking foot backwards while the engine was off with parking brake engaged. Holyshit was i scared. Lesson learned 1st or reverse no matter what.
