Jump start a 6mt?

335si · 09-01-2010, 12:42 PM

Has anyone jump started their car by pushing it and then popping the clutch (6mt obviously)? I have done this on my previous cars, but none of them had the push button start. Just curious if it is possible with these cars...

Nr!qUe · 09-01-2010, 12:45 PM

I remember reading it somewhere in the manual that this was possible. Only for 6MT of course.

Nr!qUe · 09-01-2010, 01:07 PM

Page 158 of the 2009 3 series without iDrive Manual

"Tow Starting:
Avoid tow-starting when possible. instead jump start the engine, refer to 155. vehicles with catalytic converter should only be tow started then the engine is cold. vehicles with automatic transmission should not be tow started at all.

1. Switch on hazard warning flashers, comply with local regulations
2. switch on the ignition. refer to page 47
3. Shift into 3rd gear
4. Have the vehicle started with the clutch depressed and slowly release the clutch. After the engine starts, immediately depress the clutch again.
5. Stop at a suitable location, remove the tow bar or rope and switch off the hazard warning flashers.
6. have the vehicle checked.
(with xDrvie, do not activate HDC when the vehicle is being towed.

Yep, I push started it once. Just make sure the ignition is on.

Interesting.... I distinctly remember this failing to work on my fathers M coupe. Guess I'll have to go out and try for fun.

335si · 09-01-2010, 02:08 PM

Great! Thanks guys

Coolieman1220 · 09-01-2010, 02:10 PM

i've always wanted to try this...

Doing so may cause a voltage spike and damage the sensitive electronics on these newer BMWs and should ONLY BE DONE AS A LAST RESOURCE.

This somehow doesn't sound like "fun" to me. Pushing a heavy car that doesn't need to be pushed to find something out!!

One time a guy was trying to sell me a porsche 944 (for resto) for $1200. It wouldn't start. He goes "fine.. give me $600". I said OK, and then my buddy pushed me up to 5mph and I popped the clutch. Vrooom to life, and off we drove lol.

igom3 · 09-01-2010, 03:27 PM

I did it 30 years ago LOL

BMW voids the warranty for so many different reasons such as transporting a two-legged pet during leap year without proper harnesses, can't imagine what they'd say when the DME records that the vehicle went 35 mph on the drive wheels without any fuel system in operation.

Use common sense, the BMW ain't running for a reason. Push starting isn't gonna correct the root cause and result in a vehicle that works properly.

I had this same question a while back: http://www.e90post.com/forums/showthread.php?t=72105

As stated above, yes you can and I in fact tested it. Well, kind of. I tried it with a fully charged battery in my car and it worked no problem. In these cars I think you have to at least have a battery installed and the slightest bit of charge, otherwise the electronic push button won't be able to put the car into 'ignition on' mode (catch 22).

I rocked my old civic for a week once w/absolutely no battery in the car. Fortunately I both lived and worked on a hill so it was just a matter of getting the right parking spot and not stalling it in between.

944? Isn't that one of those cars in the movie that our grandparents used to watch, like Pretty in Pink or something?

You're thinking of Sixteen Candles. The 944 is what got me into wrenching and euro cars, and I will always have a soft spot for them.

It is possible, I've done it with my 335i (6MT) with no problems - got it moving by going down a little hill.
(BTW, your R5 is beautiful)

The 944 is a sweet car. I rarely see any in mint condition, many still on the road are battered. 944 Turbo even sweeter.

[MISFIT]Black · 09-01-2010, 06:12 PM

This does work. And it doesnt take much speed as I pushed it myself. Maybe 5mph.

cotmfk · 09-01-2010, 06:48 PM

Cool, I'm glad this works!

It should definitely be used as a last resort! But, I would definitely do it to avoid the towing fee... depending on how far you have to go, that could be multiple $100s. I am out of warranty anyways, so I don't care what the DME records! I even talk with my dealership about the tune in the car, etc! Wish me luck nothing breaks, though!

Youth is wasted on the young. I used to run 12 miles for "fun" then lift for the "fun" of it because it was "fun" ... get the point...

GIGJOHNSON · 09-04-2010, 09:46 AM

I have done it. I have a relatively long driveway so I got rolling and popped second. No Problems!

GIGJOHNSON · 09-04-2010, 09:47 AM

I had the battery on btw, I have not tried it with the car completely off...
