I can relate to the noise he hears. For me it was the rubber edge of the convertible rag top rubbing against the top of the clam shell every time i went over small bumps. I put a piece of velcro( only the carpet side) on the rubber edge to minimize the rubbing effect/noise.
Johnny - talk to Eduardo who owns a shop in Fremont called Foreign Auto. He did my IMS and clutch last winter and was very reasonably priced. The guy owns a Porsche himself so he understands our emotions. If you're still looking for parts like the coolant cap, call Parts Heaven in Hayward. They are the Porsche Gods in East Bay.
My 99 Cab 996 was new to me in 2010 and I also was disappointed in the cabin noises. However, when the top was down everything was perfect. So I went thru the TSB's on the site and was able to reduce the top noises by 90%. The first change was the latches that hook the top to the window and next was putting velcro felt around the cab top pillars, and so forth. You have to be persistent in wanting to eliminate top noises but hard work pays off. FYI, all convertible rattles and sports car convertibles rattle the most. You should have heard the t-tops on my 84 iroc.
ltumacder replied to judgejon's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)I followed the advice of many on this forum and replaced the IMS when my clutch started to go last December. MY99 996 CAB Here's the breakdown of expenses. IMS bearing $619 - came with free RMS (saved $30) because I used LN Engineering online store Clutch kit Sachs (EBAY) $450 Resurfacing of existing flywheel $90 Flywheel bearing (generator bearing) $20 Labor - $940 Fremont Foreign Auto recommended by Parts Heaven in Hayward CA - the owner Eduardo knows his stuff and owns a Porsche. Total $2119 My car has 42k miles and the IMS bearing, for what its worth, was in excellent condition. However, there was oil weeping from both the IMS and RMS according to Eduardo (the car never leaked on the garage though). Eduardo always replaces the RMS when he does at clutch job at no extra charge. Bottom line is no more IMS anxiety and I feel my car is worth more now with the new uber bearing. Also, the clutch and resurfaced flywheel is a huge improvement in the car's performance. The new RMS is a freebie.
ltumacder replied to Gonzo911's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)There's a lot of fixes covered in the TSB's for convertible top noises. I implemented them one by one on my MY99 996 Cab until I was happy with the results.
Bought a MY99 cabrio last year with 40k miles and excellent condition - here's my thoughts. Definitely get a PPI from a dealer or better yet an Indy who specializes in Porsches. The indy will be brutally honest and will do it cheaper and better if he feels you may be a future customer. During the PPI offer the owner a free oil change and have the mechanic thoroughly inspect the oil filter for metal fragments. If you are satisfied with the PPI then buy the car and don't worry about upgrading the IMS until you decide to change the clutch, which in my case will be in another 5k miles. Another thing I did was talk to a service rep at the dealer where my car was exclusively maintained. I told him that I may have the 60k checkup done (a $1k job) at his location if the previous owner had neglected any periodic maintenance. So the rep told me the entire history of the car and the mileage at every visit from the first scheduled maintenance - 11 years worth of data.
I have a MY99 996 that makes the lifter noise when I haven't driven the car in a few days - especially during colder weather. Here's a link to a thread on various start up noises that helped me.
I read this http://www.macarbon.com/install_guides/Porsche/996/996%20Mirror%20Installation%20Instructions.pdf and watched this. The mirror (glass) feels like it going to break but keep pulling it and work your way around the edges like the video - it will come off. In my fix I had to remove both mirrors (glass). Like I mentioned you're not changing the mirror housing so you don't have to follow the video exactly, the video gives you a visual of removing the mirror and the motor.
ltumacder replied to DanIelT's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Can I ask where you had the exhaust done? I live in the Bay Area and have the exact same model, color, and year except its a cabrio with 41k miles.
I finally tackled the problem last weekend as the mirror was returning less and less to the original position. I guessed that it was the mirror motor slowly giving out and decided to replace it. There are two mirror motors for 996's, one for memory seats and one for without. The difference in price is $90 vs $150 for the tilt down motor. One motor has 3 wires and the tilt one has 8. I found used mirror motors for $40 from Parts Heaven but none with the seat memory feature that the tilt mirrors need. Interestingly, when I called the dealer I found out that the driver's side mirror motor is exactly the same as the passenger side. So, I simply switched the motors on my mirrors. After all, the driver's mirror does not need to tilt down. All is good now and passenger mirror returns to original position after tilting - hope this helps anyone with this annoying problem. PS. Removing the motor requires you to remove the glass first, remove 3 phillips screws holding the motor, and undo the wiring harness. You do not have to remove the whole mirror assembly.
Can you please post pics?
So I just made my first Porsche buy last Sept and landed a 996 cab with 38k miles that lived a pampered life in San Francisco ( weather is perfect for preserving cars). I too was concerned was the IMS issue and learned from the forums that if you're going to buy one of these cars, and you hate risk or have bad luck, than buy one with a weak clutch (needs to be replaced in 5-10k miles). Then upon changing the clutch you can change the IMS bearing and even RMS. My car will need a clutch next summer and thats when i plan to take a look at the rms and ims and make decision to pull the trigger. i am not totally convinced that the preventive maintenance is of value but considering we're getting these cars for 20-25% of the value they cost brand new, then we should stop whining about Porsche quality and pay the extra if you plan to keep them. Heck, I want to be the first to say that its because of the effing IMS issue I can afford to buy the car of my dreams! (Too bad turbos don't have a similar issue! :) )
Thanks for the feedback. I am going to disassemble the mirror unit and make sure the mirror is seated properly. The mirror always dips down to the curb perfectly, it just doesn't return to it normal memory setting by itself. i have either have to use the manual toggle or I can press the memory button a couple times and that usually brings it back up.
ltumacder posted a topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)SEE POST #7 I have spent a lot of time researching my problem on the many 996/986 forums so I am hoping someone who has fixed this problem can help. I notice others have had it but no one I can find has followed up with the correct diagnosis. I am driving a 1999 996 cab and when i go in reverse the passenger mirror tilts downs to the curb level. The problem is when i put the car in drive, mirror does go up, but only around 50% of the travel needed to return to the memory position. The funny thing is I can put the mirror back in its location by using the mirror toggle on the drivers a pillar. After searching on the web, I have drawn the following conclusions. 1. The settings or system needs that operate this function need to be reset by the dealer. 2. I have a bad mirror motor or control module. 3. I am not inputting the memory settings correctly, though I have tried for 4 months every possible combination detailed by this forum and many others on the web and I doubt there is another procedure i have not tested. Any help would greatly be appreciated as this has been going on for six months now and its getting very annoying since its easy to forget to adjust your tilted mirror passing cars at 90 miles per hour.
I just did this on my 1999 Cab and the sound was 2x better on the radio and 4x better coming thru the ipod. I wanted to stay close to original so aftermarket was not an option. You take a risk though buying a used radio, I am pretty lucky, bought mine on ebay and it came with the aux ipod adapter. I think the CDR-220 made my original speakers and oem amp worth keeping.
