My 1999 911 Carrera started smoking at a streetlight. Very smelly blue smoke was coming from under the engine cover. I pulled over and popped the cover. Blue smoke was coming from somewhere under the engine (not the exhaust). The engine stopped very suddenly.
We don't have a local Porsche dealer, but the Subaru dealer owns a bunch of 911s and he has a couple Porsche mechanics. I had it towed there.
The C1 fuse ("Engine Electronics") was blown. They replaced it, but as soon as they turned the key, the "cam adjuster wiring harness" (I do not know what this is) began to smoke, and the fuse blew again.
They disconnected the cam adjuster wiring harness (I don't know what this means, and neither did the service advisor), and the fuse stayed intact, and they got the car started. They were able to drive it out to the parking lot with no problems.
They said I need a new cam adjuster wiring harness (again, no idea what this is), and this would require an engine out repair, which they could not do. They estimated this work at $5,000 to $6,000.
Additionally, they did not know how drivable the car was with a disconnected cam adjuster wiring harness.
So ... how bad is this? (Service report image attached.)

I have a 1999 C4 coupe with a manual transmission. Earlier in the spring, I had the transmission repaired -- 2nd gear replaced and the pinion bearing replaced, too.
Since then, I installed a short-shift kit myself.
Today, I noticed that the back-up lights aren't illuminating. All the gears engage fine, including reverse, so I don't think there's an adjustment problem. I don't know if the lights were working or not before my short-shift installation.
What are the likely causes for the lights not working? Switch wasn't reconnected after tranny work, or the switch is bad, I guess. But could my short-shift installation be causing the problem?
To all 996 owners with PSE, especially those with a 4S.
I think my 996 C4S exhaust behaves oddly. I think it's a fault but you might tell me it's normal behaviour. The problem is that I've always had this 'fault' on my car so I don't know if it's a fault or intentional behaviour. If you have the same car, perhaps you can shed some light on this.
When I start it, it's noisy and sounds great. It quiets down as it runs for the first 5 mins.
I have the PSE system and when I press the button you can audibly hear the exhaust note change - quieter when on and louder when off. Default is off so loud.
Here's the rub. Up to around 1500rpm it's got a good noise then it fades out to the point where it's so quiet it's like driving my partners Yaris. If I keep accelerating, when I get to around 3500rpm the exhaust suddenly gets loud again. I mean it's immediate - like someones flipping a switched marked loud. It sounds great.
It happens in 2nd and 3rd gears most noticeably and the PSE is in the 'off' position. If I have the PSE button on, then it's just quiet all the time and that works fine.
So why the silent spot?
I did read somewhere that German market cars might have had a system that turns on and off the PSE at certain speeds to prevent people driving round residential streets with a loud exhaust but information is thin and I don't think I was ever on UK cars.
I have also had a small go at checking vacuum pressure at idle on both sides of the Y piece in the engine bay but both hold good pressure. One side has only a microscopic leak but not enough to cause this kind of issue.

I have a 97 tiptronic non turbo boxster. I blew my front seal so I need to rebuild my tranny. I just need to know what the parts numbers are for the bushing and seal.... I cant seem to find em and want to make sure I order the right parts.
I heard you can actually order a larger bearing and seal and then machine out the tranny where it goes into and in turn avoid this sort of issue for much longer.. if that helps identify what im needing here im sorry im sort of lacking in the lingo im still learning and will update with a better description once i can go over it again with the boyfriend.
