  1. Sometimes when there is a voltage spike to the system (like connecting a new battery) the programming can get "mixed up". When this happens the best thing to do is have a tech/shop with a PIWIS re-program the affected control module(s). I think it very rare to replace a DME if most everything but one or two items are not working.

  2. Welcome to RennTech Couple of possibles: (1) A wiring issue causing the heaters to malfunction. (2) The reflash itself. A lot of people have experienced all sorts of weird DME issues after getting aftermarket reflashes done as these systems are quite often set up to try to eek out small power gains by trying to trick the basic DME engine control functions, everything from strange codes to blocking connection to the OBD II port. Returning the vehicle to the factory DME flash put an end to the problems.

  4. I would check to make sure you reconnected the coil packs, both completely plugging them in, and not having crossed any.

  5. Yes, the control is inside the PDK. Likely best it be checked with a PIWIS.

  6. P1990 PDK Software monitoring A (or B) of signal processing unit Possible fault causes: - PDK control unit faulty Fault effects: - CAN alive counter freeze - Engine speed limitation - Transmission limphome indication in instrument cluster control unit C150 DME control module, communication Possible fault causes: - No power supply for DME control module - DME control module incorrectly coded - Short circuit or open circuit in the CAN drive - DME control module faulty (in most cases the cause is not the DME control module but incorrect coding!)

  7. If I am not mistaken CC control inputs would be stored in the DME. If yours is acting up you may have a DME with an internal short or coding issue. Hopefully you only have a bad switch as opposed to needing a new DME.

  9. Update! So I decided to start by check the driver's side, and boy am I glad I did (since the pressured line on the passenger side is such a mess to remove)-- it seems that when getting the filter seated last night, I somehow managed to have one of the electrical connectors going to the filter (the black and red cables) came unplugged!! 🙄🙄 She's alive!! 🙂

  10. Ok guys, now that this seems sorted out. In my case the problem was a faulty air change-over valve. Since I was at it I also changed the electric change-over valve. I thought I'd post an entire post-mortem on the whole incident. This way future reader can get all the info in one spot. In short, no horror stories but a lot learnt. A Huge thanks to Loren, 1999Porsche911 and tholyoak for helping me thru this. Guys, I'm going to be quoting you in the writeup below, hope you guys don't mind. If people want to read the original message and the whole thread, its below. Background =========

  11. Hi All, I'm just about to order a 2014 off the dealer lot and it doesn't have any stereo upgrades (no bose, no pcm, no stereo plius, just the 2x25 watts). I currently have a 987 that I'm trading in that did have the Bose. I love music, but this is what they got on the lot. I want to just add a simple self powered kenwood sub under the seat (sw11) or similar this year and then later on upgrade the door speaker and and a decent amp. I want to know if there is ANY way to get a line out from the factor head unit, as I want to keep that stock. I don't want to use a JL Clean Sweep

  12. PSS9 coilovers are awesome. Just got mine on as I've decided to putting my Boxster in to more track driving, but the PSS9's are great for street too (set around 7 on the shock). They are more than double what the Designtek ones are (at about £1700), but I've seen a few negative reviews of Designtek stuff (especially their exhausts) so not sure I'd trust my handling to them (especially at such a low cost). I've only managed to find one guy who reviewed putting their coilovers (on a 996). He was happy overall, but had to do a lot of adjustments to get there, and didn't have a long term revie

  13. Here is the fix for code 0740 on Tiptronic. After refilling fluid (by the dealer the last time), the code would come back after 100 miles or so. The potential fix from Porsche was a new tansmission, around $7K. Before I spend that kind of money, did some research that lead me to the following for P0740 code: Since the fluid was changed, went to step 3. Here is the location of the pressure regulator and how to remove it. You have to drain the fluid and remove the ATF pan to get to this part, then it will be obvious. There are ATF filter change instuctions in the DIY that will help wi
