Having an issue with the heater in my 2000 Boxster S. It fogs up the windows when the heater is on. If I turn the AC button on the fog stops but the air temperature is no longer hot or warm even. The moisture coming out seems to have an odd smell to it. It's either old nasty water or perhaps antifreeze. Any help would be greatly appreciated.
The common coolant pipe issue seems to only affect the V8 Cayenne's. I'm wondering if my coolant leak is a common problem too. I've been losing coolant on my 3.6 V6 Cayenne at a fairly slow rate compared to the other more common issue. I'm having to top it off about once every month or two. Last weekend I was changing the oil and started investigating the leak. It looks to be coming from a black plastic coolant hose fitting on the back of the engine, passenger side.
Has anyone seen this problem before? I'm wondering if there is just a bad o-ring behind that fitting or if the whole part needs to be replaced. And if anyone knows the part number for this I would greatly appreciate that too!
Hey guys, I have 2000 Boxster S thats been sitting for months now because it has a rod bearing issue. I found a running 2.5 for cheap becuase its a family friend. I wanted to know what would be needed to do a swap like that? Would it be harder or simple. Im thinking the DME would need to be remapped. Or is it better to sell the car as is? Im trying to empty out the garage so whichever would be faster.

I recently had to replace the water pump on my 2001 Boxster. This all went fine, however, the red light to the right of the temperature gauge is blinking at 1 Hz. I've read this indicates low coolant level. I followed the factory procedure to bleed the system and it is filled to the max, but the light still blinks. Also, the gauge is flatlined to the left. I replaced the temperature sensor near the #4 cylinder head without improvement, and the wires "look" ok. All the fuses are good. Does anyone know the procedure to troubleshoot this wiring? Or the pin and socket numbers for the wiring diagram? The temperature gauge worked fine before the water pump blew up. I did recover most of the impeller, but a few small pieces are in there.
My first post here so please bear with me but pretty desperate for help. Have 2004 Boxster S and its, in general, running a bit rough (feels fuel rich). It also will also, on occasion, not go. Pulling up at a busy intersection and car reduces to Idle. Then put the foot down and the car stays at idle. Normally an engine restart gets things going again (although not always and sometimes requires a few goes).
Bought a computer reader and found error codes
P0102: Factory Fault code 115 - Mass air flow sensor - below limit
P2135: Accelerator Pedal - Signal Implausible
P0121: Factor Fault code 117 - Throttle value or accelerator pedal potentiometer - signal implausible
P1266: Factory Fault Code 409 - Fuel shutoff function monitor - signal implausible
Took the car to Porsche. They suggest a MAF sensor was the root cause and replaced it. It felt better for a few days then problem returned. They replaced another MAF sensor.. Same problem. They then said the MAF reads 0 and have checked the cables so its me DME and it needs replacing (not cheap)
Have taken the car back home and looked at the likely affecting values myself from the computer.
The computer shows to different values for MAF
Mass air flow (HFM) is always 0 regardless of if the car is working correctly or not and at any accelerator level
Mass air flow seems to move within a range of 18 (idle) to 100 (full throttle)
2. Throttle (since it had error codes on this)
Pedal encoder potentiometer 1 and 2 always move and the pedal value goes from 0-100% when its working but stays at 0 when its not. Since the potentiometers always move I am assuming the DME simply can't add things up so sticks the pedal value at 0.
ie. The MAF sensor reading above confuses the DME and it reduces the throttle to 0. That feel consistent with the behaviour of the car (its just sticks at idle)
Any one with any clues? Certainly don't want to replace the DME unless absolutely necessary....
