Just revisiting the thread buried several pages back. You wanted to know more of the order of operation where I encounter the "bang drive" starts in my '99 9-3 so here is the scoop:
- Come home at night park car
- Do not engage parking brake, just have foot on normal brakes
- Shut motor off
- With foot on brakes, engage reverse to release ignition key
- Gently release brakes and insure the gear holds
- Return in morning to start with clutch depressed fully to floor first
- Ignition on, wait for about ten seconds (attempt to feed the motor some fuel before starting) and start car
- If bang is going ot occur car will not move backwards at this time, if it does I will of course apply brakes
- If bang is going to occur, shift lever will not come out of reverse even though car is started and running normally. Starting a second time provides no change in condition.
- From here I can engage clutch to "bang" the car into motion (pretty high up on the engagement normally too it seems like), rock like I'm mentally challenged in the seat to have the car move without hammering the clutch, or open door and start motion Flintstone style, again to avoid more violent clutch start.
Other notables:
- Clutch "warbles" especially in higher temps and frequent start/stop (i.e. city) driving. As noted prior, suspect warped pressure plate
- "Bang Drive" occurs with or without the parking brake engaged
- When parking brake is not engaged during nightly shutdown and normal brakes are released the car does move freely as it rests back on the tranny
- Likewise when I park on a flat surface and car doesn't rest on the tranny the conditon still occurs (so something funky arising from "loading" the transmission without usage of parking brake is not a strong factor)
- Seems to happen more frequently in colder temps
- Shifting action is nice, no ginding or unusual notchy feel to it (quite nice actually)
- No unusual conditions exist on the typical route I take home (puddles, mud, construction, rough roads, etc.)
- Driving fast or slow has no effect on when condition arises
- No rust typically on discs or when there is rust present, there are no skip marks from pads releasing
- I cannot recall the condition ever arising during a daily driving cycle (i.e. running multiple errands with frequent parking), only after car is stationary for a duration of maybe six hours or greater
- Brake fluid is at normal level and doesn't smell crispy
- Pads show normal wear but are not in need of replacement
About the driver:
- No, not my first manual. I have had tons of them (cars, trucks, tractors, etc.) but nothing ever quite like this
- Car is driven in a spirited fashion typically, but well maintained under my care. Seems previous owner didn't do much for it unfortunately...
- My driving position is normal in the car (no gangster position or other funkiness), pedals are easily accessible and have no discernible troubles operating
Please give feedback on anything you can conjur up. I am taking it in on Monday for an oil change and to have this looked at again (although I'm sure they won't be able to reporduce the symptom...). Any fodder for fighting/curing this anomaly is greatly appreciated!
Thanks!
