1999 Carrera4. 5 years I have chased this intermittent problem. Sometimes the car refuses to start. Starter will not turn over. All maintainance has been done at a dealer service center. They say they've never seen this issue before. It's not DME they say. Every component from entire key system to the starter, as part of the security system/start permission, has been replaced. Car can go for months with no issue, start every time, then it's like a gremlin grabs it and it will not start. No error code(s) reported. Everything appears normal and proper with dash lights. Might be a minute, an hour, a day, a week... and it starts. You never know if it will start or not.
Possible weak point in the wiring? Software issue? I'm flying blind on this.
Has anyone experienced anything like this?
Hello Renntech Community. Hope everyone has had a lovely day/ evening. Well... After owning 2 previous porsche's there is no doubt we all run into A LOT of issues. I have an 04 Boxster S with 117K miles on her. Well taken care of, just recently had an oil change. While driving my car on the interstate i felt a drag in the acceleration.It felt like the clutch was slipping but after driving it a little more it cleared up... (Previously was an oil leak, I tightened the drain plug and added more oil prior to this incident and all was well) Then, while driving the car would accelerate any more, I attempted to downshift but it kept happening. The car died after I pulled off on the highway and after continuous hours of attempting and failing I called a flat bed and had her taken home. I ran tests on the relay, All is well with it. I added gas and a octane booster to attempt to clean it out. That didnt work. Checked fuses and those are all good. I suspect a fuel pump but Im not sure. Thank you!
- Hopefully this is all enough information to help me out

Hi all, just purchased a 1961 notchback 1600s, I have never drove a Porsche until the day I purchased this car, got the bug now and i love Porsches more than ever now, the car is in very good shape, but i want to change all the fluids, grease all the parts, and do all the maintenance there is, the oil was so dark when I checked the level and it was all the way to max line of the stick, i would appreciate if you guys can tell me where to buy all the maintenance parts, and where can I buy the shop manual, and what are the things I should do, there is a small leak on the floor from engine very small, but a palm size of oil from transmission on the ground, thanks guys cheers😁
This will be my first post, thanks for a great forum !
I've recently purchased a exhaust system from Design911 in the UK which has the valvetronic function on. This is said to replicate the PSE which my car does not have factory installed.
Wired it up and put the vacuum hoses, tested the system and it works fine.
Over to the issue for my car:
When starting up the car, the neutral positon of the valves is open, which means a lot of noice from the exhaust.
When switching this by the solenoid, sending vacuum into the system and the valves closes. This means less sound.
But when the valves is closed the car wont run properly at the RPM range of 5500-7000 RPM's there is also fault codes for misfire on cylinder 2.
The strange thing is that this works perfectly when the valves is open. I've tried two differnet vacuum sources, into the ressonator and also for the left hand side cooling system vacuum solenoids. Without any differnce. I tried to run vacuum directly to the vacuum actuators on the exhaust without any difference and also tried manually applying vacuum and using a one way check valve to keep the vacuum while not connected to the cars vacuum line. No vacuum leaks, no fault codes when driving with the valves open.
Same result every time. So have anyone had some similar issues to their car ?
Thanks in advance for any help !
The left door key switch on my 00’ 996 c4 will not lock or unlock. I took the handle and bracket out of the door frame. I was told what usually breaks is the cylinder but nothing appears to be broken. I don’t want to buy a new key so simply replacing the bracket isn’t an option. Is there a straight forward solution or do I need a specialist??
Any my feedback would be much appreciated thanks!
