Pretty hard to tell without an accurate description... But yes it sounds like your coilpacks. If they are still OEM and done over 100k kms, with a little bit of moisture they tend to f**k out. When mine went, I had just washed my car, drove fine until I tried to give it shit, then it felt almost like boost cut, no power at all.

If it was doing it all the time, check your fuel pump/filter. Maybe you were starving it of fuel.

So was it just a certain point in the power band or it just wouldn't accellerate at all ever? Or would it drive normally if you babyed it, and only 'died' when you tried to rev it a bit?

Alternator should provide all the voltage needed while car is running. Technically you could remove a battery once the car is started and not notice anything.

Check the links at the battery terminal

Maybe cam or crank angle sensor?

My vy did the same thing, only the engine stopped completely and I had to restart the car. No noise, no splutter - just died.

Turned out to be the distribution module underneath the coilpacks, which got the signal from the crank angle.

There's a link for ECU there, pull that out and the engine will shut off. Happened to me on my R31 and R32. Don't know about the newer cars.

Yes you can pull the battery out, just remember where the alternator wire connects to.

Sorry, I wasn't aware of that wire. Disregard me then.

Sounds the same as what mine is doing. Completely cuts out, like it cuts the ignition, could pump the throttle and nothing. Then it comes back running perfect like it never happened.

thats exactly wat its doing... i started it yesterday and it didnt miss a beat i have no idea what it could be :/ anyone have any ideas? could it be a an airflow meter ? coilpack?

same thing happend to mine , was the AFM. I swapped it over with a working one and has run fine ever since. I would start with the cheapest and easiest options first then move on to the harder and more expensive items.

      How old is too old for tyres?

      By Murray_Calavera · Posted

      If the tyres were fitted when new, I wouldn't expect much over 5 years of use. Especially if the car lives outside full time.  If the tyres had been stored under ideal conditions and are being purchased new, I'd fit a set of already 5 year old tyres if I only expected to get 1 to 2 years of use out of them.  I've purchased many a set of new (but quite old) tyres from St George Tyres when I just needed some decent rear tyres to drift on.  Here is a pretty crazy example, can't say I've ever bought 11 year old tyres from them before though lol.  https://www.stgeorgetyres.com.au/momo-tyres-245-45-17-outrun-m3-official-product-by-momo-italy.html

      Also, a tip for young players  Check the dates on new tyres before they fit them, I always ask this question at the tyre shop, as they have tried to put "new" tyres on one of my cars a few years ago, but the build date was about 3 years old

      Yeah - 4 or 5 years is the limit for decent tyres. Pedestrian grade tyres with 400 TW ratings start out hard and don't start to suffer until they are somewhat older again. But the stickier decent stuff? Nup. My current ADO9s are < 2 yrs old, 17000km in, only have about the minimum 2mm of tread depth left, and they are.....not what they used to be. They are clearly much harder now than when new. Whether that is heat cycles (unlikely, for a road tyre), different compound between top and bottom of tread, or actually aging out (in less than 2 years!!!) is not really able to be discerned. But I'd credit actual aging as being at least part of the cause. I've got an old pair of ~50% worn AD08Rs in the shed that I really need to get rid of. They started feeling waaaay too hard to put back on the car after a couple of years sitting there.

      Personally I wouldn't put tyres over 4 or 5 years old on any of my own cars. Once they go hard the grip characteristics completely change. As per most things it only matters in an accident and that's when you most want them to do their job!

      I'm replacing the front tyres on the E39 tomorrow because one of them has a few gouges out of it. There is so much tread still on them but they're also 9 years old and the rubber is super hard.  This falls within the guidelines of 10 years old that I've read which surprises me given their condition.  I'm curious about whether you guys care about tyre age or just judge the tyre based on condition? How old would you consider too old?
