I'm guessing this is the same on all modern Porsches with manual gearbox- you have to press the clutch pedal to start the car.

Mine has developed an annoying fault whereby it sometimes won't start even with the clutch pressed fully down. Starter motor doesn't spin, and a message appears on the dash saying 'depress clutch pedal' or something like that. It will eventually start after brutal mashing of the pedal into the carpet. I guess there's a switch down there somewhere that needs replacing or adjusting.

Anyone else hasd this fault?

Needs a new clutch pedal switch, a fairly common issue.

Before repalcing the switch make sure that the carpet, or over mat if there is one, is not stopping the clutch pedal being fully depressed.

Mustangs have this system too, I have always thought its just another thing to go wrong.

Shouldn't be an expensive fix surely?

My C2S had this switch replaced. I'd have checked the cost, but all of the docs went with the car when I sold it. It was replaced under warranty though, FWIW.

Thanks all. Car is still under manufacturers warranty (2010 Cayman), but with my OPC if I don't tell them exactly how to fix the problem they'll just say they couldn't find the fault.

I've been living with the issue for a few months now, but last week on the channel tunnel shuttle I couldn't get the damn thing to start when the time came to disembark. Embarrassing.

The switch may just need adjusted rather than being faulty. You can also just unclip the wiring plug and jumper the terminals, or jumper them across the rear if you need a quick ferry disembarking solution.....or want no switch

idea Reading OPC? I had two separate problems that took three visits each to rectify. And each time I was asking them to check the same thing. Class.

Back on topic - I hope you get it resolved quickly. A car that won't start isn't much fun, unless it's so good looking that you've already got it parked in the living room.

You can adjust the switch yourself until you have time to take it to porsche for them to replace.

You need to get your head under the steering wheel (with your legs out of the car and a mat under your butt on the sill) with a torch. You will find the switch under there and you will see/feel a little piece of metal resting on the clutch pedal lever that is pushed into the switch when the clutch pedal is pressed down, this activates the switch. You need to bend this bit of metal towards the pedal lever, so that it gets depressed fully when the clutch is depressed. Then it will work again until it gets bent out of shape again.

Must say it's a crap design and is very annoying when it goes wrong. OPC will replace it for you... but figure it out yourself also so if you need to adjust it in future you can.

Is it an easy job to bypass the switch?

Just had a go at this - awkward job or what?!! Many thanks for the tip - the car now starts every time smile First service due next month so I'll get it looked at properly.

No problem, it's handy to know. After you figure it out first time it's a 30 sec job to repeat.

My clutch switch is being replaced today (2011 cayman) - how come the much touted German engineering on a premium car lasts less than 10,000 miles before standing you in the country nice meal at a pub in the middle of absolutely nowhere.

My 987 Boxster has this problem, intermittently. It is preceded by the oil level countdown and then depress clutch message and so takes some time to infuriate you.

It seems to be related to the time between putting key in lock and turning it - putting seatbelts on, or perhaps unlatching the roof.

Had the same problem last year just before I was due to drive across France and didn't want it failing whilst abroad.

There are two switches mounted on the clutch lever mechanism, a red bodied plunger switch and alongside it a light grey unit with a stainless steel lever. It is the grey lever switch that fails.

Looking up in the drivers foot well the grey switch cannot be seen directly as there is a black plastic air out let duct in the way, the end of the red switch and the wiring to both is visible. However if the steering column is lifted to its full height the switch is visible with the aid of a torch through the gap between the shroud and the lower dash panel.

Real pain to get at and might not be the same on yours (mine is 09 GenII Boxster) but had to remove the ducting first.

The switch doesn’t have to be removed, but to start the engine the two wires on the spade terminals need to be connected to each other.

Mine been running like this since, I haven’t sourced a new switch yet and don’t know if I’ll bother as a Porsche one will probably fail again, though I don’t suppose they are that expensive.

Cheers,

Simon.

The one on my 2009 987 failed last year. Porsche Reading replaced it under warranty, said it was a well known fault. On that basis I asked if Porsche intended to replace the switch with a more robust design but got no answer. Interesting to know it can be over-ridden. I might do that because it's a real PITA and all because Americans can't be bothered to check cars are in neutral before firing them up hehe

Mine had the same problem - OPC changed the switch but problem was still there. Eventually the starter motor was the problem. They changed that and it starts a lot more purposefully now.

Cambridge fixed mine.

I think there may be a specific workshop bulletin/campaign or recall as my clutch switch was replaced recently on my 2010 997.2 GT3.

It went in for other things and when i got there they said that the clutch switch campaign had just happened so they would do that and another one on DME reprogram/update, which was a massive software download from Germany. This was four weeks ago, but I now can't recall what the DME rationale was. Will see if the memory banks are a bit sharper after a morning coffee!
