2003 Boxster 986 S, drove from South Wales to Silverstone and back to South Wales, 70mph on the motorway with the roof down, had 31mpg average. Always filled up with high octane fuel, tyre pressure even, etc. That's with driving super carefully around towns as well though. Anything else and it starts to drop quite drastically lol.

I drive mine in the winter and I love it. Scarf on, top down, heaters on, smile away :)

I don't see any issue to be honest. As long as you service and look after your car regularly, and you'd drive responsibly in the cold, then driving in the winter shouldn't matter at all. Good coating of wax to protect the paint and make sure those tyres have good tread. Job done!

I've had a few ideas for a few projects on the Porsche, and they involve adding features with new dashboard buttons.

I'm quite new to electronics, so I just want to check I'm right in thinking these would work. The original dashboard buttons have 5 pins - left button, right button, 12v, backlit LED and active LED. I'm only interested in the first three for now, so each diagram has a switch with three terminals.

Would these work?

OEM dashboard Footwell lights button with two-stage brightness

One-touch roof with emergency stop button

OEM dashboard spoiler button (one-touch)

The 'timer' relays are timed delay relays, with times set on each one via the on-chip dial.

If someone could check that, that'll be great :)

Thanks!

To be honest, there's mainly two people who own this calibre of car. People who can afford it and buy it because "Oh look I own a Ferrari" and know nothing about cars, and the people who buy them through appreciation of what they can do.

If it's the former, you'd be wasting your time worrying about their opinions. If it's the latter, everyone appreciates these cars as a whole. I love Porsches, but I adore the engineering that goes into Ferrari's too. And it'll be the same story with people who own Ferrari's that buy them for the love of driving. They'll know a good car when they see one.

Don't worry about it. Enjoy your car and spend time with people who share the same passion :)

That's the kind of advice I like to hear.

Ah okay.

It'll be quite hard to diagnose as it only happens after a hard drive and cools after a short while of stopping. They'll have to catch it while it's still hot.

Shall do.

What do you mean by the leak hitting the heat shield? I had a quick look under the car and couldn't see any heat shields over the cats. There's heat resistant material under the rear bumper but nothing directly over the cats.

But then, it does sound like it rattles as well as splutters. That's what made me think of the internals of a cat.

But you're 100% certain that it would always throw up a code if the cat was at fault?

Very good shout. It'll be hard to diagnose as I'll have to dive into an exhaust garage and ask them to check it immediately while it's still hot...

That only happens while hot?

Understandable, I'll order one asap. Thanks for the help!

Thanks!

But you think it's definitely exhaust related coming from that video? Luckily I have a friend who will lend me a cat to try it to rule it out.

Sounds like exhaust heat shields or internals of cats/mufflers or exhaust brackets. You need to jack up the car and use a mechanic's stethoscope to probe around to pinpoint the source of the noise, maybe with engine revving.

Unfortunately I can't. It doesn't do it on cold, and if I heat it up enough to do it, it'll be far too hot to touch.

Just updated the videos as they were the same.

I've posted in other forums, so I thought I'd throw a thread in here too.

I'm getting this horrible, loud, spluttery rattling sound coming from the rear left of the car after the car's been driven quite heavily. If I drive the car carefully with low revs, even on the motorway, it's fine. If I push the car hard with the engine a little below running temperatures, it's fine. However, when the car's at running temperature and I start to drive heavy, this spluttering rattling starts to happen. If I start to drive calmly after it, it'll start to go away again. And so on.

There is no loss of power, no error codes, nothing. I thought it was bad sparks or coils but I've tested another set with no results. It sounds more like an exhaust blow.

Here's the videos:

Inside the car:

Outside the car:

But like I said, it only happens after the car's been warmed up and after driving hard. It'll go away or won't happen at all if I drive it carefully. It sounds like it's coming from the N/S rear.

Could this be a failed cat? With the insides rattling when it heats up?

Some advice please! Many thanks :)
