    Brand new turbo, very sick engine...

    Picked up my new meteor TT yesterday (photos follow soon when the weather improves). Was driving home via a scenic twisty road when the engine suddenly died. At the time I was coasting to a stop and MAY have accidentally had the car in gear, hence stalling it. Not sure about that. Anyway I tried to restart, but no action from the starter motor. Then noticed a message on the computer to depress the clutch - I hadn't been aware this was necessary, but once the clutch pedal was depressed the engine started immediately.

    Straight away I noticed that I had almost no power and the engine was running really rough, almost like half the spark plug leads had been pulled. I headed straight back to the dealer, a slow and very disconcerting trip, where profuse apologies were offered by the service guys. After having previously read that this sort of thing can happen when an intercooler hose comes adrift, I suggested they check that first. The car then spent 15 minutes in the bowels of the service department, before being returned to me in perfect running order.

    Their diagnosis was that the car had been running on just 2 cylinders, and somehow I'd fouled the plugs! The fix was to give it a decent rev for a few moments which apparently cleaned up the plugs to proper working condition.

    How did it happen? They felt that I may have hit the gas when the car failed to start, which possibly flooded the engine and consequently fouled the plugs. I don't remember hitting the gas but it's certainly possible, however I would have thought that in these days of fly by wire controls and computers, it is pretty unlikely.

    Since this little hiccup I've done about 250 miles with absolutely no repeat of the problem. The dealer advised "drive it like you stole it" right from the showroom, and my manual makes no mention of running in rev limits so I took them at their word. Although I drove fairly sedately most of those 250 miles, on a couple of occasions (well, maybe ten), I did some passing where I ran the revs momentarily up to a good 5,500. The car is amazing!!! It was raining, and I felt I was pretty close to the limits of adhesion as the car launched itself and I just held on, but I'm still wearing the grin 12 hours later! What an adrenalin rush!

    Now I know that the 10 month wait, the crazy money (especially here in Australia), the moments of doubt, the distraction and debate over possible supercar alternatives, have all been worth it. I'm about to indulge my passion for fast cars like never before! Reality has exceeded expectation and I wholly recommend this amazing machine to anyone considering taking the plunge.

    you just bought the best car in the world confort/power/quality/money.
    enjoy in good health.

    Re: Brand new turbo, very sick engine...

    Unless they changed the manual, there is a suggestion to keep the car at a lower than redline rpm before the break in is complete.

    Also, given the nature of the egas system of throttle by wire, I wonder how it is possible to "flood" the engine with petrol when the engine is not completely on...

    My manual definitely makes no mention of rev limits during running in. Under "Tips for Running In" on page 8 it advises during first 3000 kms (1865 miles) that you "take longer trips, avoid cold starts with short distance driving, don't participate in motor racing events, and avoid high engine speeds especially when the engine is cold". Nothing more specific than that. Different manuals for different markets I guess. It's also worth noting that we only get a 2 year guarantee here in Australia.

    Re: Brand new turbo, very sick engine...

    Within a few days of the delivery my brand new 986S several years ago (still have it!) the engine went nuts. It shuddered, spit, stalled and scared the cr*p outta me as I was forced to the side of the road. Did it once and NEVER did it again. Official conclusion (no error codes): there was a one-time snag in the brand new parts; like a burr or impurity of some sort which had it's effect and then broke off or flushed out. Hopefully you'll never have whatever happened happen again.

    That kind of explanation is a lot easier to believe than fouled plugs on a brand new, computer managed engine. Got up at 4 am this morning and went for another long drive, everything running perfectly now.

    OMG, it's like I have a new woman! I just can't keep my hands off this beauty (I think my wife is getting suspicious!). Even now I'm agonising over where we will go for our next date, and counting the hours...

    Re: Brand new turbo, very sick engine...

    had a similar incident on the first day...stalled it leaving a stop sign with traffic behind me ...engine died and wouldnt immediately restart until i turned the key completely off, clutch in ...seemed to take about 2hrs as i was reeeaally worried the next in line would rear end me...which they didnt...and all has been perfect since enjoy

    I think the 997S and 986S (my 2003 BoxsterS) have pretty much the "same," highly complicated electronics and other engine systems. Both allow for attributing these problems to something..., ahem..., "magical," which happens just once.

    When it happened to me I was anxious for a while expecting a repeat occurance and a chronic PITA. It's good to hear you received the necessary checkup and reassurances and so have quickly regained confidence and enjoyment of the car! Wheeew!


    Re: Brand new turbo, very sick engine...

    @Nickoz: many, many congrats on your new TT. I'm sure that your bond with your new car will only strengthen and deepen as the miles go by

    Just a couple of little things... the sport shifter doesn't mean you have a different gear lever... just a different shifting mechanism inside with less of a shift throw

    Just remember, you need to press the clutch pedal fully every time you start the car

    About break in: it's recommended to keep the revs below 4200rpm for the first 3000km. Having said that, the GT1-derived TT engine is very strong and can take a lot of abuse compared to the M96 engine in the Carrera and the M97 engine in the Carrera S.

    Mate, enjoy that car to the max

    Re: Brand new turbo, very sick engine...

    Thanks easy_rider911. Got the clutch figured now, it's a good idea but it would have been nice to know about it before I left the dealership and headed into the wild blue yonder (engine was running when I got in).

    I'd seen pics of a different gear lever on sport shifter equipped cars which was why I was a little concerned. But as soon I put the car into gear I could tell it was something special. I really like that short throw! Very easy, precise, and none of the notchiness I read some people encounter and also no extra effort involved in changing at least not that I can notice. A very worthwhile option!

    Also thanks for the tips on running in. I'm going to try very hard to contain my enthusiasm a little, at least for a while!

    Re: Brand new turbo, very sick engine...

    Forgot to mention... probably one of the most important precautions you should always take both during break in and beyond (i.e. throughout the life of the car) is to wait till the car is really properly warmed up before you drive at high revs... i.e. wait till the coolant temp is normal (around 80C) and the oil temperature is around 90C... it takes longer for the oil to reach the right temp and it cools faster too if you take a short break before resuming a drive...

    Re: Brand new turbo, very sick engine...

    Good points.

    My possible breakin superstition? Better to have a dozen or more cold-hot-cold cycles during the 1500-2000 mile initial break in rather than just a few. IOW, a bunch of 50-100 mile trips are better than three or four 500 mile trips.

    Re: Brand new turbo, very sick engine...

    ER & MMD, thanks for the thoughts. Most helpful and duly noted!

    Nick.

    It seems like we pay about the same as you pay in Brasil. In the US they could buy 3 TT's for what we pay for one!

    Of course when we sell the car here in Australia we get a much better price than the US. A one year old TT would sell here for around US$300.

    Had the same thing happen to my 997S about 3-4 months after I took delivery and had washed and waxed it. The engine shuddered and sputtered. It hasn't happened since then. Sounds like some humidity-induced "gremlins" might have caused problems in the electrical/ignition system.

    Re: Brand new turbo, very sick engine...

    I've had a similar problem with both an earlier 997S and also a new 997 turbo - in both cases the car stuttered and wanted to stall at idle if I didn't play with the gas peddle. I attributed to first case with the 997S to bad gas, I had filled up in a small New Hampshire gas station about 20 miles earlier. The second instance with the turbo happened after the car had been sitting for six hours and it was raining. After a warm up period the engine smoothed out and has not returned, but in both cases it was very disconcerting. The turbo has 3,000 miles on it at the time. No codes in either instance, and no answers from Porsche.

    Good to hear I'm not the only one. As my friend Rummy used to say, "stuff happens"!

    Re: Brand new turbo, very sick engine...

    Another explanation, based on your description given above, would be referring to the engine management's intention to keep it running at minimal RPM. As you can experience on several cars, cautiously launching the car without applying the throttle, the ECU will independently counteract to prevent stalling. In your case, depending on the rate and duration of deceleration, the system might have forced gas into the cylinders to prevent the engine to go below a given RPM limit. Just a thought.
