06 M3 died out while driving and had to be towed home

As a new member, I am asking for some help. I have a 2006 M3 convertible that my wife was driving the other day. She was just cruising, when all of the sudden it died and never would start again but does crank over. She did not notice any idiot lights before it died. Had it carefully towed back into the garage where it is currently sitting. Car has about 55,000 miles. Fuel pump primes when key is turned on. The car is sounding strange when it cranks over. Just keeps cranking kind of slow, but does not even hiccup. Please help. Is this a broken timing belt??? Fuel problem??? Spark problem??? Any suggestions would be great. Thanks in advance.

Are you still under warranty? Why not take it to the dealer?

Sounds like something fuel system related. Fuel Pump/Fuel Filter/Spark Plugs are the first things that come to mind.

Plugs/Battery i would think. I am not sure if its the same as an e30 but fcsteve had the same problem. i guess the battery didnt have enough to give it spark and we used my car and jumped his and it started right up.

+1 on the dealer. Could be anything. But if you're not getting an SES light, I'd guess (and guess is the key word here) that it's fuel system related.

My warranty ran out at 50,000 miles. Is there a schrader valve on the fuel rail somewhere that I can test for pressure? I can hear the fuel pump when the key is turned to the on position. Does my car have a timing belt or chain? I will try to jump it. To the garage I go.

Well, I tried to jump the car to no avail. I think it is a fuel problem. I have two new questions:
1. Where would be the best place to check the fuel pressure?
2. Where is the fuel filter located?

Thank you.

Look for the fuel filter cover on the bottom of the car. Not sure exactly where. The diagram on RealOEM doesn't tell you exactly.

Hopefully those links help.

if you're in the mississauga area give techmax a call - ask for attila 905.795.0419. Tell him what you told us and I can almost guarantee you he'll know what it is right away.

I agree tho sounds fuel system or battery related

Battery is perfect. Checked spark-OK. Replaced fuel pump-No help. I will be towing it to the dealer next week. This was my last resort.

I'm sorry to hear about your car problem. I too,just recently bought an 06' M3(coupe)I've had it a month.I drove it all over the place the week or so,then I had the orange SMG light(tranmission) go on and I was scared.I took in to the dealer,it's still under factory warranty and all it was was a relay which they replaced and the DME recall(emissions) was done at the same time.


Sorry for the rant, but please let us know what the problem was/is when you find out.GL man and I hope it's nothing major.


Oh btw,if you know a BMW "indy" shop (not dealer) it might be worth towing it there first,tell them you want them to "READ" all your fault codes,at least this way your aware of the issues with your car before the dealer "tells" you whats wrong with it.Just my 2 cents...

Towed the car to the dealer today (love BMW roadside assistance-FREE towing) and they claimed that the cylinder #3 was not showing any compression. They said that one of the valves "kissed the piston". Probable cause- overreving. NO WAY! I baby my car. That is not the reason, BMW USA had better be involved with this. There had to be a defect in the building process. My car is just out of warranty at 56,000 miles. The dealer said that BMW may still help me out. I pray that they do. Anyone ever experience this valve hitting piston problem on a car that is driven carefully?

Sounds like a money shift. 6sp?

SMG--- and my wife was driving it when it happened.

Damn that scares me. It better not happen to me. Keep us updated as to what happens.

Same thing happened to me last Sunday and had to get it towed home.
I pulled these fault codes: 2C 8F 69 0E 01.

2C : Thermal oil level sensor
8F: E-box fan
69: Engine coolant temp. plausibility
0E: Tank small leak
01: Fuel pump relay

I don't hear any buzzing/energizing/pressurizing sound when I turn the key. I had checked the fuse (#54) and replaced the fuel pump relay, but it doesn't fix it.

I guess the fuel pump is done, what do you think?

Please advise

Thx

Fixed it. It's the fuel pump.

Didnt you replace the fuel pump at home?

Yes, I did. At first, I planned to have it done at an indy. shop, but found out it's not hard to replace so I did it myself. Saved me $400 for labor and towing.

Your wife should only be allowed to drive your ///M3 in the "P" mode...just J/K
