Whats up guys. So guess what! I got a nice list of issues that I'm trying to get straightened out, some assistance from you all is welcome and appreciated: )
Some of these I've found the resolution for, but I want to mention them all just to be thorough in case they might be related to some of the others.

First Issue, which I have found the resolution for but am just mentioning, a stuck ignition key with a side of accessories not powering up. Resolution I found here along with this writeup. Basically for those who dont want to read the full link, its a broken ignition switch that breaks due to cheap plastic internal parts. A inexpensive replacement can be had (so I read) for less than $20 and its a DIY type job. The writeup looks like it is fairly straight forward. On top of that, my windshield wipers, AC, and whatever my detector is wired into are also suffering from this by not powering up after start. After starting the car, wiggling the key counterclockwise back a bit, it re activates those units.

Ok on to second issue, which might still be related to the first. I dont seem to be getting cold air from my AC now, and the intensity bars are not stable. Meaning the air is blowing, but is not frosty fresh, and the readout on the display will show 3 bars, but fluctuate itself up to 4, 5, then back down. Weird. Also, using my durametric and the 6.x version of their software, I got a Air Conditioning fault code 31: Fresh air blower fault. So any thoughts on this?

Third I appear to have the same issue as many have had with ABS/PSM errors on lowered cars. I also am having the symptom of my right front caliper suddenly deciding to engage. Happens usually in a fast banking corner if I am on the breaks any random bit, it can happen. I haven't tried to reproduce it in a consistent manner yet as I've read many people complaining about something so similar that its probably the same thing. The caliper engaging does not come with error codes when it happens. The ABS/PSM warnings come on together, but not with any more drama from the car. So I found this thread about ABS/PSM Failures and I am thinking from these items I've just mentioned, I also might just need to get a new wiring harness and have it installed. However, I have a couple more issues that might or might not be related to this, so let me run them by you.

Fourth, I have also seen a warning/error for uneven brake distribution. Has come around twice now, around but not at the same time as one of the ABS/PSM warnings.

Fifth, My durametric is giving me an unknown error 17. Its under the ABS, thats all I am getting about it.

Sixth and final, left turn signal sometimes blinks quick, other times goes back to blinking normal speed. It was blinking quickly for some time I thought I had a bulb out in front and was just dealing with it. It started blinking normal speed again though and I tested and both front and rear were functioning. New issue or related to #1/2?

Any assistance you can lend to what I've already dug up on some of this stuff would be awesome. I am just going to move forward with the ignition replacement, I think that will probably fix #2 as well, it was working fine before this weekend. The ABS/PSM codes scare me, I probably wont trust the car until I can deal with this. Any of you folks who had this problem have a thought about it? Might have to make a trip to see my mechanic this week. Thanks guys!

Hi Justin,

I dont want to sound harsh, but why load us all down with fault after fault. Get the iggnition fixed. Reset the ecu. Drive about for a while and see what happens. If you dont all you are going to get is pages and pages of possible causes when you haven't even fixed the one you do know about.
Once you have resolved that issue you might find all the rest clear up and there is no need for ant more info. If the Issue's still occur then we all know that at least one fault has been fixed and can think of other causes. Until then it will be impossible to work out what is going on with your car.
Good luck.
I for one will keep reading. Let us know the iggnition switch replacement.

Yup will keep you posted, thanks man.

 

Since you lowered the car and had {I hope} the corresponding re-alignment, etc., the owner's manual says that you have to reset the steering angle sensor each time their are suspension changes. This could be the cause of your PSM/ABS problems and needs to be reset with one of the Porsche computer/analysis units. I'm not saying it couldn't be from a bad wiring harness or a failing ABS unit, but you should still do the recalibration anyway.

 

Don't bother with the steering angle sensor, it wont make any difference just a waste of money. Your tires are different diameter on the front and back therefore triggering the PSM & ABS when cornering or braking. They are out of spec somehow. Did you recently change tires?

 

+1

had the same issue a while back. the shop said the problem was with my steering angle sensor and a speed sensor. $1k and 2 weeks later, parts were replaced and problem was still there. threw on a set of stock wheels w/ stock tire sizes and the problem disappeared.


also, the abs/psm light reappeared when my alternator was going bad. problem went away again once replaced. I've only seen one or two instances on this board where it was due to a faulty wiring harness.

 

Thanks for the suggestion. The car was actually lowered by the previous owner, I am fairly confident he took all the necessary measures when the job was done.

No recent changes to the tires or the car. I am close to being due for new tires in the rear so I might just expedite their demise and have a new pair ordered and installed along with an alignment. If that fixes the issue I'll be happy. Is this a common occurrence to these cars when tires start to wear? Thanks a lot guys, I'm hunting down the ignition switch to fix that issue today, at least that will be out of the way: )

Ok here is an update for those waiting. Replaced ignition switch over the weekend and have been driving the car for the last couple of days. All of my electrical and ignition problems are resolved. However, I am still getting ABS/PSM errors simultaniously at random times. Happend twice today, low to moderate speeds, driving in a straight line, no braking. Time to take it to the shop I think. Thanks for the help guys.

 

Hi Justin,
I'm sure that has made it much easier now that most of the problems have gone.
I have had the ABS/PSM happen for a few weeks last winter.
I did 2 things at once to rectify the problem and not too sure which did it.
However they were
1. Took out MAF and cleaned it
2. I had Brand New rear tyres and legal limit 1.6 mm on th front. I had 2 new tyres put on the front the day I cleaned the MAF. Coincidence????
Frank.

 

Thanks Frank, can a novice undertake the MAF cleaning job and get it done with relative ease and quickness?

Justin

 

Absolutely YES No Problems. I used a contact cleaner that leaves no residue at all and is safe on all plastics.
Just take it out, spray it , let it dry out for 10 minutes & put it back in.

If I can find the link on 6sp for the Job I will post it. Three are a few if I remember.
Frank

 

This should be it...

There are more I just picked on this one.
Good luck
Keep us all informed.

Awesome, thank you for doing the leg work and digging that up for me Frank, I will give it a shot when I get a chance next week and pass along any updates. Again, thank you very much!

Justin

 

Your Welcome.

 

Ok update time. I went through the process of cleaning my MAF using Adam699's writeup located here. Pretty straight forward stuff. My voltage checks were within spec before and after cleaning, car ran smooth before, still runs smooth. I need to put some miles on it to see if I can trigger the ABS/PSM warnings while moving though, as I have only been able to put about 10 miles on the car today after the cleaning. That being said, my Durametric is triggering them every time I have it access the ABS module. I get the warnings on the dash, but Durametric software is not putting up any codes. Shutting off the car and restarting it will clear them...until I check that module under Durametric again. I have seen this with both version 5.x and 6.x. I'm thinking I've done my due diligence as far as my capabilities and it might be time to have it looked at by a professional. I'll probably see if driving it around in the next few days gives me any codes, and go from there. Any further thoughts are appreciated, will keep you guys posted. Thanks again.
