  1. Wanted to give everyone a recap (warning, this might be boring) hopefully it will help someone down the road.

    01 Box S, tip with 77k miles. Was leaking oil (very tiny drops) about a month ago, so figured I'd do the IMS retrofit and RMS at the same time. I removed the tiptronic myself (I highly recommend NEVER removing your tiptronic), and had the car sent to Jim Ellis Porsche in Atlanta. For 410 bucks, they did the IMS and RMS. The car was towed home, and I re-installed the tiptronic, and drove the car for about 250 trouble free miles....

    ...then, while driving on the highway, I noticed the CEL, and at idle, it felt like it was "surging"...got codes p1340 and p1341

    My first reaction (as with many here) was that the tech at Jim Ellis must have done the IMS incorrectly. In fairness, (and Jake confirmed this) if the dealership had done the job incorrectly, the CEL would have triggered immediately...it was just very bad timing (excuse the pun) that the CEL came on so quickly after the IMS.

    As it turns out, it was the variocam (the accuator sp?)...Jake discovered a very small piece of debris had gummed it up. No bent valves, so engine doesn't need to be replaced (not yet, anyway).

    If I could go back in time, I would have just had Jake do the IMS and RMS from the start. Not that the dealer did anything wrong, but just that Jake does SO much more than put the IMS in - they replace, test, drive and retest , and, of course, because Jake's level of knowledge is second to none.

    Thanks for the input, everyone!

  2. Car is currently at Flat 6...had a chance to meet with Jake Raby, and it was an honor. The shop is off the beaten path, but once you're inside, you realize very quickly that flat6 is more like a lab than a shop.

    Seems pretty unlikely that I could have driven the car 200 miles without triggering the p1340/1341 - for now, it's just a coincidence that it failed so soon after the IMS retrofit.

    Bank 1 is out of time by 23 degrees - it's more than likely the engine will have to be replaced...but we're not positive yet. According to Jake, a guide rail might have gone, and he hasn't ruled out the accuator yet,

    I'll keep everyone posted...and thanks again for the replies

  3. Well, Jim Ellis Porsche of Atlanta called to say it might be an accutator, or it might have just "jumped time"...either way, it's 1300 just to remove the cover and take a look and figure out what's wrong. Which seems a bit odd, because (according to flat 6) the variocam job total is 1,000...

    They also stated that the recent IMS job and the timing issue have no chance of being related.

    The car is heading to another shop for another opinion.

  4. Retiming is not required if the IMS change out is done correctly. As yours is a five chain motor, it should have been a relatively simple job to lock the engine down before changing the IMS. Without a full analysis of exactly how the service was done, it is difficult to positively connect the two incidents; but I have to add that if your cam timing is off, it would not be the first time I've seen this happen...............

    seems odd the cam timing would be off after 200 miles - it was a rather sudden event - one minute, it was fine - the next, rough idle. Had the IMS been done incorrectly, wouldn't have the engine thrown a code and started rough idling immediately?

    one other question - if this were a faulty sensor, which sensor would I be looking for?

    Thanks

  5. Thanks Loren

    I removed the tipronic, then shipped the car to Jim Ellis Porsche in Atlanta - One of the notes I put down was, please advise if car needs to be re-timed after IMS installation...I believe I read somewhere that it would need re-timing, but the tech that did the IMS stated that re-timing was not needed because the car was never out of time.

    I can not say thank you enough for your reply.

  6. it's been over 200 miles since the IMS - seemed to have been running fine - then today, I felt a slight (what I can only describe as a misfire) rough idle at stop lights. Seems to be running fine - I reset the codes, and they came back within 20 miles.

    Any advice or suggests are greatly appreciated, thanks

    01 Boxster S tiptronic 77k miles

  7. well, this one is a mystery

    hooked the durametric to the box s, and it said "0 errors"...but even with zero errors, the P/d4 alternating blinking was still happening. I clicked "clear codes" just to see what would happen, and sure enough, the alternating flashing stopped, and the error code went away.

    If I had to guess, the tip threw the code because it was disconnected...

    hope this info will help someone else who ever removes there tiptronic

  8. Tiptronic trans was working fine before the removal - it was removed with no problems, and I made a custom craddle for it, to ensure it's safe removal and storage while out.

    Everything is back together, car is running fine, but I am getting an error code (flashing p then d4) from the tiptronic - I don't own a durametric yet...just wondering if anyone here has removed and replaced their tiptronic, and wondering if I've missed something simple...I have two idea of what it could be -

    1) the coolant was low in the trans when I first started the car

    or

    2) the tiptronic was locked out at TDC...after re-installing the flywheel, I hand rotated the crank to make sure the LN retrofit IMS had no contact issues (it didn't). But the engine was no longer at tdc...does the flywheel only attach to the torque converter in 1 position?

    Thanks in advance for the help!
