Car didn't start today?!
 
So, I got to start my car today, first I hear my radar decetor is going off! I forgot to unplug it, but it wasn't the first time and in the past I never had problems starting...

so, I go, everything looks ok, I start, NOTHING, and car seemed like it restarted... when I try to restart, don't even get any crank, just a weird noise.. other lights all work and everything, but no way to start the car. The clock got reset to 1200, and also the drivers window got stuck at the slightly open spot, and my remote control wouldn't lock the car (had to do it manually).

I highly suspect it's battery... so gonna jump it tomorrow, but wanted to share to see if anyone has any other suspicions?! I am surpised that the window wouldn't go up to lock position, and remote wouldn't lock the door. Could it be some other electrical issue?

Thanks

Alex,
Battery would be my number 1 suspect particularly if the car hasn't been started for a time. Can you measure the voltage? Is the battery a few years old ?
Although the clock is a low power device, the battery voltage may have taken a dive during the starting attempt.

There's virtually a 100% chance that it's the battery. If you have a battery charger, I'd recommend letting it slow charge today rather than giving it a jump start.

I have heard that jump starting can hurt the electronics on newer models so a charger would be my choice.

Battery; 100%.

If the problem is the battery and the problem arose due to leaving the radar detector on, I would venture that the battery was nearly depleted. Either a bad battery or some problem in the charge system. A V1 only uses while in operation 0.43A and when on and idling just 0.23A and it would not deplete overnight a battery even with minimal charge.

I don't have a charger, so can either jump it, or ask Porsche road assistance to come charge/jump it?! Do they just do a charge?

don't get me started (sorry, couldn't resist....)
 
Hope it's the battery, if you have a couple of hours, here is my story of the last 6 weeks (condensed). Bought used 05 997, 25K mi, 2 owner from independent dealer in PA (I'm in FL). Not CPO. Drove it home (3 miles) after offloading from the transporter, into the garage. Washed it an hour later and got a "Systems Failure" message. To the dealer. (30 miles away, 2 days of ownership). At the dealer for 3 days, no diagnosis, so went and picked it up. I replaced the battery because the old one was a low budget unknown unit (got Interstate per this forum). Drove 1 week, and took a day off to go to the dealer to have the fog lights/daytime running light settings changed (no Sport Chrono)--the CD ate a disc on the way down. Diagnosis=toasted PCM. Drove the car home, took one short trip to the bank, car won't start (!). Charged the battery, (new remember) and tested the battery and charging system, the alternator is intermittently giving good/bad charge numbers. Starting is intermittent as well. Needless to say, I'm searching this board and getting great feedback from everyone to try to ascertain the direction this is heading. Back to the dealer, 2 weeks, (I pointedly requested they check the alternator, battery, alternator cable, wiring harness, starter wiring as these are also known issues that cause "no start" or slow start conditions--THANKS TO EVERYONE! Sidebar: I have been communicating with the PA dealer because I want them to take this car back or help me with this issue ($45K paperweight in the shop). After 2 weeks, diagnosis is alternator. New PCM is installed (no NAV, so $1700) Went to the dealer to pick up the car (as the PA dealer has arranged for a "sister" Bosch shop here in town to replace the alternator at their cost) and of course the car won't start. SOOOOOO, they jump it, I drive it back, have it on the charger and it goes in tomorrow for the alternator swap. Of course, I will have this shop ALSO look at the cable, wiring harness, starter, starter wiring, etc for a second opinion. I have some concern about the attention that was paid to the car at the dealer because in the midst of the 2 week stay there, the dealership was sold (!!!) and everybody there was walking on glass wondering what the future held. Current status is that I still have a $45K paperweight in the garage that I can't trust, have had the car for 6 weeks and driven it one of those weeks. Hope it's the battery, but spend some time searching this forum so you're armed with some info if it is not. Good Luck!

If your problem is the battery (likely) you need a new one. It's easy to replace - just get an Interstate battery.

For the OP, suspect the battery, as others are suggesting. You don't mention the mileage or the MY of the car. (Helps us to know what car you're talking about). For a Canadian, I would think you're on borrowed time with a MY05 or MY06 car with an original battery. The issue about the door side window going down to the 'opening the door height' is quite normal. You don't want to close a door fully where the glass has not come down a bit--it can do some damage. It probably lacks the power to return to the fully closed position. You're better off with it down a bit. After you install a new battery don't forget to train the windows.

For the later poster, there were some issues with the MY05 alternator cables not having sufficient torque on them. Recall on these cars that the alternator and voltage regulator are a one-piece unit. Sometimes the voltage regulators are bad, instructing the alternator to curtail charging the system prematurely. On the other hand, you don't want one over charging either or it will boil the battery. I would love to know the service history on that car--how many batteries has it had in it, etc. Don't fret--you have a $100K car that you only paid $45K for so you have a way to spend to get it up to speed.

MY07 C4S, 9K miles (14K Km), and I am on original battery. How do I train the windows again? Is a jump gonna hurt anything?

Window training is in your Owners Manual.

Jumping does not hurt anything if done right, but it will otherwise. Jumping instructions are also in your Owners Manual.before recharging it.

Edgy01 Feb 21, 2010 06:26 PM

Your mileage explains a lot. Not enough of them. Porsche will warranty a battery for up to two years as long as you are accumulating at least 6000 miles a year. You failed that test.

For the windows, Run them up and when they reach the top continue holding the button (up) for about 3-6 sec. more to train the windows in where 'up' is. Ditto for the down.

can't top this
 
just offloaded a 09 cs, 7500 miles on her. from hennessy in roswell ga. i live in jersey. drove it first time on friday- 2 days ago. when i accelerated on the expressway she started to miss and backfire. i pulled over, turned off the car, restarted and everything was fine the rest of the trip. today, sunday i go to start my new toy, and she will not turn over. just great! less than 50 miles and i can't even go for a spin.
can't wait to hear what the problem is.

check if garage opener still works and if you have heated seats - if that work. I do not remember for sure but there are some functions that get affected when battery slowly dies out.

Starting from jump cables is fine - get cables connected to other car, open your trunk and turn off your ignition, connect cables to your battery, get other car RPMs to 4K at least, let it run like this for 4-5 minutes, then try to start yours. It you have voltmeter make sure your voltage on your battery when your car runs is about 13.5V+ or what it is supposed to be on Porsches, you`ll see - if alternator is gone it will be way low close to 12V.
