what is an 'early' 3.4 996?

To the Alps!

Every day is a lesson, I didn’t know they did the RTS for the 996 cabrio. Is it the same as the 986 in that you can’t put the roof down?

Sounds like a fabulous trip.

[Dammit]

Once the RTS is on the roof has to stay in whichever position in was in beforehand- takes 30 seconds to take off if you have a friend to help you though.

It’s essentially the same as the 986 RTS but a bit longer due to the extended cabin vs the mid engined car.

Nice! I want to do a eurotrip in mine next year. Definitely going to do the Spa classic, not that it's very far!

And this is why the very early cars have less bore score. The pistons were coated with something that is better at preventing it. I believe that means 97 and 98 and maybe some 99.

If thought bore scoring was a result of cooling issues?

Which is why the larger capacity engines suffer more (996 3.6 and 997 3.8)… and why it is almost always on the same cylinders on the left bank of the engine.

I’ve not heard of 3.4’s of any year suffering from bore score (not saying categorically it doesn’t happen, but if it does it’s very rare).

Mine did.

1999 C4 Tip, 173K miles, discovered scored this January.

Fantastic, thanks.

So recently my car has started doing the double beep after locking (normally some time after locking, 20-30 seconds or so.

Hooked my Autel ap200 up to it and it looks like there is a code 34 'passenger compartment monitoring sensor'

I guess this is the IR movement sensor? Anyone seen something similar at all? Any ideas on resolution? Car locks and unlocks fine so it's an annoyance only really but would like it to not happen!

Mine did it last month. And then the airbag light came on. It was something to do with the locking mechanism on the driver's side door and it somehow aso affected the door airbag connector. Sorted quite easily (not by me, my indie)

Does it not set the alarm off after a while.? Mine does this and sets the alarm off after a while. Mine has also been diagnosed as my passenger door lock.
I really must get round to fixing it....!

Nope just beeps and then seems fine.

A lot of people talking about door locks so will look more closely at this...

CAZ or TFL?

I got the CoC from Porsche for my 1998 996 and my 2001 996 and some of the numbers on the 1998 are higher than 2001.

175k miles has got to be approaching rebuild time on any sports car, hasn't it?

I certainly wouldn't expect a Porsche engine to run forever without any issues.

I think @Chris Stott has done better than that on the original engine. And he even lets his wife drive it.

All original engine.

Car is now retired. Trying to find a way to get it down here to Spain… may involve having to export it to Ireland 1st.
