I hope it's OK to ask this in this forum. I also searched and couldn't find an answer to this or even someone having a similar issue. I recently changed the lithium battery on my 2019 Cayenne for an AGM one and I now need to register it so that I can get rid of the battery warning every time I start the car as well as the start/stop warning every time I stop while driving. I first tried with my Foxwell NT530 and, even though I was able to get rid of all other codes, I couldn't get rid of the battery-related ones. The tool even has a screen where I can set the new parameters: Capacity: 90 mA, instead of the original 60 mA Technology: AGM, instead of the original Lithium Manufacturer: VAR (code for Varta batteries, even though the new battery is an EverStart Platinum from Walmart), instead of the original LG6 (for LG Chem) Serial Number: 1234567890, instead of the original 10-char number However, once I enter them and hit Save, I get an error saying something like "error writing codes" without more details. My next attempt was PIWIS III on a laptop. I am using a virtual machine image with version 41.500 of the tool. I am able to detect and connect to the car just fine, even clear faults, but again, none of the screens that I found that let me change these 4 parameters (through Diagnostics > Gateway and several other menus that read "Battery" or "Batterie" in German) and they all give me a similar error. I can provide screenshots of that helps in case someone is able to assist me. Am I out of luck trying to do this on my own, meaning I will need to take it into a local shop? Which, by the way, I also attempted and two shops I talked to swore that they had a PIWIS and had me come in only because they were sure their Autel would do this, only to give up and give me my the car back, defeated. Thank you in advance!

Update on door harness fix 2025 Hi Guys, I had to deal with this issue again in 2025 on both sides and got everything fixed using these pins male / female from Amazon . The male pin doesn’t go in far enough because of the shoulder diameter, so you have to drill the hole a little bigger to clear the shoulder. Good luck

Thanks very much, Loren ! The code worked like a charm.

I'd start with that new plenum installation.

Thanks, there are no codes and it seems to be running fine, I just never noticed it before this past weekend. I had the car about a year and have driven it ~4k miles. I had wondered if maybe it was normal. I installed the IDP plenum about 2k miles ago.

You can check it with a scanner for a vacuum leak - but what you might be hearing is the intake suction.

Good evening, I just purchased a 2001 Boxster 986S, and the Becker CDR 220 needs the code to activate. Type: 4462 S/N: Y5046052 Any help is greatly appreciated. EA

The video is my 99 996 C2 Cab w/97k miles earlier today. Recently I noticed this “gasping” noise when I accelerate quickly. If I accelerate even a little slower no gasp. I’m guessing an intake or vacuum leak but cannot isolate. Overall it’s running well. Any ideas? IMG_9539.mov

I purchased an 04 Cayenne with the ignition lock issue. I have pulled the entire interior out and found numerous corroded wires, to which i have repaired. long story short. I have used my Lunch x431 and a couple of other scanners and I get power to the DTC but no data. With ohm meter I get no signal from pins 6 and 14. pin 4 and 5 have good ground and 16 has good voltage . I have the tools to program new key, kessy, ecm etc. but with no data input I am dead in the water. HELP/ can I jump 6 and 14 to somewhere and get can high and low?

Disconnecting the battery will clear codes and reset some modules to their default profiles (Disconnecting the battery will still erase the "adaptive" or "learned" driving style settings, but it will not fully reset the DME to factory defaults.) but does not reboot anything in the DME, the system is purposely designed that way.

Any truth in disconnecting batt for an hr to hard boot the DME or is that an urban myth.

Then I would say put the car back to the way it was, clear all the codes and see what happens. This is strange.........

Hey John...thanks for getting back. Im sure about tracing wires to the harness pins 10 and 12 for the wires i spliced. Correct volages at cam sensor plug. I don't know if they pass thru another device ...from the looks of the diagram it dosent look like they do. Wires are still there i can revert if I have to.

Sorry for the delay getting back to you, took a couple days off over the holiday. From the sound of it, you missed somewhere when you tried replacing the cam sensor wiring with jumpers. Are you absolutely sure you traced the correct harness wires for cam sensor #1? Did you check to see if the wires from the sensor pass thru something else (another device) on the way to the DME? Using the axiom to always go back to where you were before the problem, can you go back to the original wires or were they cut away?

Hi Ive lost my radio code for my 99 Boxster CDR 22 Type 4467 Serial Number X5011921 any ideas on how to get a code - none of the online services seem to recognise Cheers JB

Ok now I went into PANICK MODE. I did what I said what I was going to do...essentially replaced the red/blu 5v wire between the DME and cam pos.sensor plug and FAILURE car dosent start. Tested voltage to red/gry wire and got nothing ...supposed to be 12v. Figured I disturbed an already failing wire...replaced wire between DME and plug and now have my 12v on red/gry 5v on red/blu and ground on brwn/Pink wire (ignition on) and...FAILURE. Car cranks begins to turn over briefly but won't start. What the hell did i do. Checked all fuses in foot well the stereo fuse was blown somehow. Other than that they were all good. Please help. Thanks V PS getting pending p0638,p2122,p2127 CELs. Throttle sensor

The EU mandates using only non metallic anti seize compounds for environmental reasons, so the compounds available there tend to act as electrical insulators, which can cause plugs to misfire. Here, anti seize compounds are metallic and therefore both electrically and thermally conductive and work fine on spark plugs. We put a small dab of a high quality anti seize compound on all spark plugs, new or old, and have never had any issues.

Need Radio code for new to me Boxster that has battery replaced. CDR210 Serial number 2282H50V5011796 thanks!

If you have a scanner it should be able to tell you which cylinder(s) have a misfire.

Newer plugs have a coating which obviates the need for antiseize. I only use it if reinstalling for some reason. Are certain your coil packs are seated and all wiring is intact. If you have a new problem after some work, they are probably related.
