2003 986 Boxter Battery - Alarm - Frunk
scanner-1 replied to Steve-O-Utah's topic in 986 Series (Boxster, Boxster S)
Congratulations on having a very rare car—the 1993 Boxster, haha! Don’t tell anyone, but some people have relocated the emergency frunk release to the tow hook screw in point in the front bumper. -
Once engaged, it works at all speeds unless the vehicle comes to a complete stop--in that case, you will have to hit resume or the accelerator pedal. I don't know what that icon is, but looks like it might be some form of lane keeping assist?
-
In a 2011 (958) it's called Adaptive Cruise Control (ACC).
-
It works as you might expect—open door, turn key, close door to set. The real trick is (and maybe this is just mine) when you open the door, there is not enough time delay to get the key in and disarm the alarm, so I always set off the alarm when getting back in!

I have that alarm on my ‘86 Targa.

That definitely sounds like symptoms of a MAP (or MAF) sensor issue. My 2011 CTT will on occasion behave like you describe and it is easily remedied by removing the sensor and spraying it with MAF sensor cleaner. I'm guessing this happens about every 20,000 miles or so on mine with 100k+ miles. I bought a new sensor just in case, but it just rides along in the glove compartment waiting for the day when the cleaner stops working. If I let mine go long enough, it will eventually throw a "P1637 Pressure sensor ahead of throttle valve" code. Pretty sure your engine has at least one, check this part #: 94860618000,

Diagrams are from my Bentley manual covering 1997-2004 Boxsters. Note: these diagrams are for 2001, but there are no later years in this manual (maybe 2001-2004 are all the same?)

Update for anybody still wondering: I swapped my new Shrader equipped wheels on to my wife's 2013 Cayenne Diesel and had the exact same issue (front wheels not identified). I went to TPMSdirect and bought 4 HUF IntelliSens for $33 a piece. They arrived in BHsens IntelliSens boxes with a sticker saying they were programmed for a 2011 Cayenne Turbo. Same indy installed and 5 minutes later they were working fine. I'm pretty sure that HUF is the OE for Porsche and BHsens is their joint venture with a Chinese company. The sensors look, smell, taste and act like the genuine part. Bottom line: DO NOT buy Shrader 29138 for your 958 Cayenne.

So it's a few years later, a new set of wheels, tires, TPMS, and unfortunately an update on what TPMS does NOT work on my 2011 CTT: My old UVS2000 HUF Intellisens (installed 2017) were still working fine when I had my indy install a new set of Porsche wheels and Pirelli tires (went from 20" to 21"). I was unable to find the same sensors (discontinued) and my search led me to some very reasonably priced Shrader 29138 (Pre-programmed for Porsche) sensors. After install, the Porsche relearn procedure would only pick up the two rear sensors. After multiple tries and a call to Shrader tech support, I swapped front wheels to rear and rear to front. Again only the rear two sensors were picked up by the TPMS system. My current theory is that the Shrader TPMS outputs at a slightly lower signal strength and is unable to reach the TPMS antenna located on the rear axle. Any other thoughts or experience with these particular sensors is appreciated.

Just to be clear, there are two "resets" available under the Reset PCM menu: 1.Factory Settings 2.Vehicle Handover Vehicle Handover is the one you want.

Oil Pressure Control Valve location?
scanner-1 replied to scanner-1's topic in 92A (Cayenne) Part Number Requests
Many thanks Loren. That diagram was exactly what I needed. The valve in question is hiding in plain sight on the front of the engine, well obscured by the serpentine belt and a host of pulleys and not easily accessible due to radiator, etc.. For unknown reasons, the wiring was severed about four inches from the valve. The wiring harness gave me just enough play to back it out and do a soldering job in the left front wheel well. Reconnected and the code is now clear. My next question is, what is your source for the diagram? Do you have a repair manual recommendation? Locating that particular diagram would have saved me hours of fruitless internet research--Thanks again! -
2013 Cayenne Diesel Problem: P164E00 Oil pressure control valve: electrical fault (No check engine light) Does anybody have any idea where this valve is located on the 3.0L diesel? I think I have found EVERY sensor/control BUT this one--is it underneath the intake manifold?

Yes-ish, it works in slow and go traffic. It works pretty well if you never come to a complete stop--if you do, you will have to hit resume to get the car to continue. Overall, I'm not a big fan of the system (although this could be because I'm not a big fan of the push towards automation of street vehicles--especially ones that are so good to drive). My biggest complaint is that in traffic it is not aggressive enough when re-accelerating (car ahead moves out of the way or picks up speed quickly), which invariably leaves enough gap for another vehicle to cut in front and actually push you to the rear of the pack! For me, it's best use is on the long single file construction lane that you can't pass or be passed on, it will keep perfect trailing distance and keep you from rear-ending the vehicle ahead as you fall asleep.

I think you’re looking for Adaptive Cruise Control (ACC). Don’t know when it first came out, but it’s on my 2011 Turbo. If it brakes the vehicle to a complete stop, it requires you to hit the resume switch in order to accelerate again, other than that it works like you’d expect.
