Can you describe the problem more?

Hey gang: My 2009 daily-driver Boxster (2.9) is hesitating before turning over. The problem is most pronounced after the car has been sitting overnight. The dealer replaced the battery, but it has not addressed the problem. Any thoughts? I'm afraid it's going to leave me stranded at some point (but that's not keeping me from driving it!).

As background, I bought the car new and it has 29,000 miles. My previous Boxster was a 2003, hence the AS2003. That car had its engine replaced under warranty (IMS failure).

Thanks in advance for your thoughts.

at least my 2009 997S with DFI has a recall on the High Pressure Fuel Pump (HPFP). While mine isn't acting up, one of the signs is not turning over right away. Do you notice any loss in power/hesitation? That's another sign. I brought my car in for something else and the service tech told me about the recall. I believe they call them a silent recall. A normal recall has a notice mailed to owners.

Do a search for HPFP and see what you can find out. Other manufacturers have had issues with them as well. You might be able to research some of the issues and see if you have any of them.

Unfortunately, the 2009 2.9 base engine is not a DFI. There is no hesitation or disruption in power delivery once the car turns over. It doesn't appear to have thrown any codes out either, although during one particular slow start it did quickly state something with the word "workshop" in the trip computer display. I assume it said "take care to workshop," but it only briefly appeared. Odd.

It's likely the clutch pedal micro-switch.

I replaced mine a week ago and posted here about it at the time.

The dealer checked the Bbattery voltage and charging and told me everything looked fine. Per the clutch micro-switch, the car is attempting to turn over, so I don't think it's the switch. It's my understanding the car would do nothing if the micro-switch wasn't working.

You can recall warning messages on the OBC. In the MY10 Boxster Owner's Manual, the procedure is spelled out on Page 136: "INFO Warning Messages". I'm sure it is located on a similar page in the MY09 Owner's Manual.

You're right - if the starter motor is engaging, then the micro-switch isn't the problem.

Wasn't sure what you meant by 'turning over'.

"turning over" usually refers to the engine rotating.

So are you saying that there is no delay before the engine rotates but there is a delay before it actually catches (starts)?

Yep, there is a delay before it catches. It's back at the dealer. I'll report back when I know more.

... Tend to have that hesitation.
Could also be the ignition switch acting up.
Happy Boxstering
