My 1984 944 still has it's original air conditioner and refrigerant.

READ ANSWERYears of 944s with the same heater control lever as a924S
Thursday 02/02/2023 | 1988 | 924S | Cables and Controls | 108 views
Reason for question is that replacement heater control levers are not available. Searching recyclers for a heater control arm for a 924S doesn’t seem to turn up one. However, I seem to recall that 944s for some years prior to somewhere around 1983 had the same dash as the 924S, so if I had the years, I could try again. It’s cold around here in the winter! Thanks, Rick Heyke

Sunday 01/29/2023 | 2000 | Boxster S | Electrical | 126 views
I have a 2000 Boxster S with approximately 35,000 miles, it is a weekend driver and doesn't see track time. I recently had all four O2 sensors replaced, however the check engine light keeps coming back on. My mechanic loaded new software and reset the check engine light, however the light keeps coming back on. The vehicle diagnostic report now shows error codes: P0102, P1126 and P1133. The Hot Film MAF Sensor has not been changed. What is going on and what steps should I take at this point?

My mechanic has reset the computer twice now and updated his software, however the check engine light still returns. The engine still runs strong. Does the MAF sensor also need to be replaced.

Hello - I've recently installed the PCCM+ unit in my 996 40AE car and have been really enjoying it. The unit has been great in use, however, there is one bug within the software that has been getting more attention. Specifically, at random, PCCM+ will cause the trip odometer, avg. consumption, speed to reset. This happens completely at random and I haven't figured out if there is anything I do to trigger it. I've spoken with one dealer about it but they didn't seem to know anything and could ...

I just shipped my 1997 Porsche Boxster to Puerto Rico from Europe. The car runs on 98 Octane fuel however I cannot find a gas station in Puerto Rico that sells 98 Octane or higher? Are there any other alternatives? We got caught in a rain storm and lo and behold did not know that the drain plugs on the car were plugged. We bought the car about 6 months ago and discovered that mice hd chewed a few items, including the convertible top and foam boot. The form went down the drain holes clogging them. In the rain storm the rain could not exit the car and water came into the cabin and puddled under the drivers seat. Car had some erratic electrical issues and then ultimately would not start. I have done a ... My Boxster Spyder was in an accident in August 2022 and has not been driven up to temperature since. My situation is worse than a well-prepped winter storage scenario because the car has been moved around short distances in the time ever since (around the body shop and storage facilities). With parts supply chain delays, I anticipate getting the car back in summer 2023 so it will probably be a year out of commission. The fuel is at a half tank and I added fuel stabilizer about three months ... Are original replacements available through Classic Porsche? I'm interested in the porsche classic retrofit for my 2010 997.2 Twin Turbo Cabriolet? Hi, I am thinking of replacing the suspension on my Cayman as it has some miles and feels a bit rough.

Water leaking into the passenger side seat well. I have cleared the drains , replaced the weather striping to the soft top and still no luck. Should my next move be to replace the weather stripping on the rear window. The water appears to be accumulating at the the lowest point of the rear seat.
