This past weekend, I performed an oil change on the 2007 Coupe. Everything went extremely well. I started up the car to check for leaks and all looked good. Then all of a sudden, the car shut off! Turning the key yielded nothing! After the car sat for a few hours, started right up again. Then after 5 minutes or so, shut of again. Left the car alone for the rest of the day.

Next morning. started the car up and all is back to normal. Wonder whether I had an oil level or flow issue that the sensor detected. If so, I think it would shut off the car to prevent damage. Any thoughts? Maybe CPS? Haven't been able to pull any codes. Probably will try again later today.

 

Nothing at all, no click, no starter engagement, no turning? If none of that, not CPS. The only thing that makes total sense is seizure, then cool down. OR more likely, something unrelated.
After re-start, did it drive, or just idle?

 

If it is oil-related, then you either did not put enough oil in (and I know YOU would not do that) or I'd wonder about the new filter.

I'd take the holder out and inspect the filter - has it collapsed? Is it saturated with oil - if not, then oil is not flowing.

 

No Click; No Starter Engagement; No Turning. Completely dead! Let it sit for a couple of hours & car restarted. Ran 5 minutes or so and then shutoff. Let it sit all night. Started it up the next morning and it's run fine ever since. Never did see whether a warning light was triggered right before shutdown. Always was outside of car when it happened. RATS!!! If it was seizure, surprised I didn't see car shudder or shake. Car actually only shutoff; like someone turned the key to off.

Now here's the thing. When I added oil, I poured it thru the oil filter housing. Did this before & had no issues. Car was up on ramps, so it was elevated a little. When I started it the next morning, while it was running, I backed it off ramps. Been on level ground ever since. And so far, no recurrence or issues.

I'll comment on pizzaguy's post above separately.

 

I added 8 quarts of oil. That's what I've always added during an oil change. I know it's suppose to be 8 liters (8.5 quarts), but I did 8.5 quarts once right before a ToD weekend and I kept getting the high oil level alarm during all the twisties. When I got home, I pulled out about 1/2 quart & afterwards everything was fine. And at 8 quarts, the dipstick shows full on my 2007 (on level ground).

Now funny thing is I thought about the oil filter that night while reading a performance magazine. So the next morning, I removed the oil filter cap & filter. When I checked the oil filter, it looked to be installed correctly; that is the upper most marked line was slightly above the bottom of the oil filter cap. Filter element was saturated with oil. I checked for tightness; everything seemed okay. But being overly cautious, I removed the filter element from the cap and re-installed it, slightly twisting it as I pushed it up into the filter cap. Everything looked solid & as before. For what it's worth, I used a NAPA 7078 filter element (fleece-type) which I had in the garage cabinet & was the same version that I removed during the oil change..

I re-installed oil filter & filter cap. Torqued the cap to the proper tightness. Then restarted the car. Checked for leaks - good to go. And as I stated above, backed the car off the ramps and let it idle. Ran for 15 minutes without any issue. Figured whatever happened mysteriously went away.

Kinda nervous!! Can't really say anything I did corrected a problem. And if the motor locked up due to an oil flow condition, I'm really nervous!! Car seems okay now. Drove it around the neighborhood on Monday after washing. Drives fine; idles smooth.

Gotta pull codes & see what pops up.

Yeah, sounds electrical, not oil related. Double check battery posts, RCM maybe. When turning the key, put the headlights on, if they are dim and get worse when you try to start, I'd look at battery and cabling. IF they are full bright, and don't change or only get slightly dimmer when trying to start, I'd look at starter motor/RCM circuits. RCM would fit for engine stopping while running as well.

 

I hate garage gremlins!

 

I doubt that battery is the issue. Now I did still have the OEM Varta in my 2007 Coupe. Nine years of trouble-free service. But the last few weeks, I got the mysterious "spoiler gremlin" whenever I started the car. Even after a full charge, the spoiler opened when I started the car. So I replaced the battery with a Duracell from Batteries Plus. (Note: FWIW - The Duracell H6 battery is slightly taller than the Varta. Just enough that the leading edge of the clamp contacts the edge of the battery when you tighten everything down.) Got a 10% off credit since I bought it online & picked it up at the store. Cleaned the cable connections & posts before I re-connected everything. So I think I'm good-to-go there.

I haven't experienced any of the issues surrounding "mystery no starts" or engine shutoff like a lot of owners have experienced. May be just getting around to my turn.

How much fuel was in your tank while the front of your car was up on ramps? Squirrel Crusher

 

Just over 1/2 tank
