Technical Q&A
On June 12 I submitted a question regarding my occasional inability to start the car because the automatic oil level measuring function would not allow me to get past it. I received a response on June 18 that was not helpful. Is it likely that the clutch interlock switch is defective?

In my inquiry of June 12, I explained in detail how the oil measuring function blocks me from starting the car. Sometimes I need to attempt to start it 30 or 40 times, trying different options (ie, waiting the 5 seconds, withdrawing the key, using the "cancel' function with or without withdrawing the key, taking my foot off the clutch after withdrawing the key, and all combinations of sequences of the above). Eventually, and inexplicably, something works (usually not the same sequence) and th ...

I am wondering if you could be of help to understand when Bilstein will have shock absorbers available for my car. They have been "out of stock" since last year and no one seems to know when they will be available again. I even wrote (via Linkedin) to the person who seems to be in charge at Bilstein - Steve Beaty in San Diego (linkedin.com/in/steven-beaty-a

Monday 07/20/2026 | 1988 | 911 Carrera | Engine
After not being started for 10 years, my engine had new plugs, ignition components, fuel pump, and DME unit installed 3 years ago during its restoration. Injectors were cleaned. It starts easily when cold and idles well after starting. While still cold, however, when I disengage the clutch at a stop, the RPMs will often plummet and the engine will stall. It restarts easily. Once the engine is warm the problem disappears and it then idles well at stops. The engine performs perfectly well ...

READ ANSWERHigh oil light on 981 cayman s
Friday 07/17/2026 | 2014 | Cayman S | Engine
Changed oil before heading out on a 2,000 mile road trip. No issues during the trip. Upon my return, the car sat for a week before being used again. When I did use it, i drove for about 20 miles. Stopped to run an errand. When I returned, started the car and yellow high oil light illuminated. Wouldn’t think the oil is actually high since I drove it 2,000 miles following an oil change with no issue. Called my local dealer who concurred that oil is likely not too high. He said maybe moisture in ...
READ ANSWERHigh oil level light just came on.
Friday 07/17/2026 | 2014 | Cayman S | Engine
I just got back from a 2,000 mile road trip. Had oil changed before I left. No issues of any kind during the road trip. Temperatures and pressures always good. Couple days after getting home, I drove the Cayman to town to run an errand. About a 20 mile trip. Was parked for about 20 minutes. When I restarted it, I had the high oil warning light. Dealer says that given my scenario, extremely unlikely that oil level is high. Said might be some moisture in the system and let it cool down and try ...

READ ANSWERShould I replace the Dual IMS Bearing on a 99 996 Manual since it just crossed 85k miles?
Thursday 07/16/2026 | 1999 | 911 Carrera 4 Cabriolet | Engine
I've had the car for about 12 years and haven't had any issues with the engine or transmission (recently had it flushed). If I do the bearing, I would likely do the clutch and the flywheel with it but it there are currently no issues with any of those systems. Since the 99 has a duel bearing, is the risk lower than a later year one with a single row bearing? If I were to do it, would use LN Engineering Replacement Solution. Any risk of introducing new issues? Thanks for the advice and co ...
READ ANSWERWhen I tried to open the convertible top on my 1990 944S2, the passenger side opened but not the driver's side.
Wednesday 07/15/2026 | 1990 | 944 S2 Cabriolet | Other
The top then would not move so I drove it with a partially opened top to a collision center and asked them to look at it. They were able to get the top closed but said they could not diagnose the problem that appeared to be electrical in nature. I was surprised by this, since I did not expect the problem to be electrical. I checked the fuse and it looked okay but I don't know how to check the relay. And if the relay is bad, is a replacement available in 2026?Thanks for your help ...
READ ANSWERThe top for my 2001 996 Carrera cabriolet will not activate up or down in high temperature conditions. If I love it inside and allow it to cool down, everything works fine. My research indicates that the convertible top relay is highly sensitive to heat and internal solder joints age, expand and crack under heat. I'm fairly sure this is the problem, as it is a 25 year-old car. What is the correct replacement relay and where is it located? Under dash or behind rear seats
