  1. This works on my front doors only, its also supposed to work on the rear door correct? All of the 4 buttons on the door handles work to lock the door, and only the 2 front handles work to unlock the doors, but not the rears. Any ideas?

    I just bought an '04 CTT. The Keyless system totally confused me at first. You only have to touch the handle with the keys in your pocket and the lock should open. The button on the door handle is for LOCKING. Hold the handle and push the button when you want to lock it up. However, don't pull the handle and push the button or you will roll down all of the windows as my wife discovered on one of her first drives in a massive blizzard.

  2. WOW, finally i found one person that knows what they are talking about. All the kids that use the balancers here are horrible, some don't even know about staggered wheel sizes.

    I see that you are located in Toronto! Do you work at a garage in Toronto? Is this something that we could bring to you for you to check out and perform properly as described?

    just a couple of points since I worked 8 years for an OE on working on suspension/steering/nvh problems

    (1) it is true that many techs do not know how to use the road force balancing machines

    (2) most dealers do not do a good job of keeping their RFB machines in proper calibration - calibration takes 2 minutes and all you need to do is follow the screen prompts

    (3) many techs when installing new tires, especially on 18"+ wheels, tend to put too much lubricant to help with the tire install on the wheel. This is great to prevent side wall damage but it poses other problems. Because the lubricant takes some time to dry, it is common for the tire to slip on the w heel. Hence, you may have a good balance but on your first brake application, the wheel moves position and your balance is out the door.

    (4) most tire machines do not do a good job of seating the tire bead. after driving on the tire, the bead will seat and your original balance will no longer be good.

    what I am trying to say is that there are many factors in just tire balance alone that can cause issues.

    I would recommend going to a dealer or tire shop that

    (1) uses a RFB machine ie: a Hunter GSP9000 or similar

    (2) request the balancer be calibrated prior to using to balance your wheels (again, this is a 2 minute job and they should be doing this daily anyhow!)

    (3) inflating the tire to seat the bead, then deflating and re-flating again can help with seating the bead seat properly - also hitting the sidewall with a rubber mallet during inflation helps

    (4) ask what kind of lubricant is used to install the tire on the wheel - the wax type is best as it dries quick - if they use soap, request that they wipe off all excess soap from the bead before they inflate the tires and seat the bead

    (5) when balancing, request that they do a "dynamic" balance first but then do a second balance to correct the "static" balance as close as possible to zero

    finally, if your dealer or independent has a on-car balancer (or finishing balancer) request that they perform an oncar balance. This will yield the best results for vibration as you now are balancing a corner and taking all imbalances into consideration ie: tire, wheel, rotor, driveshaft etc... I hear that Porsche dealerships do have this equipment (Hoffman on-car finish balancer) but I dont know as I have never been to a porsche dealer. I buy all my cars used and do all my own service/repairs.

    on a side note, when I got my 06' (almost 2 months ago) there was a bit of steering roughness + shimmy and body roughness at hwy speeds. I didnt have time to balance the wheels but I lifted the vehicle, loosened all lug nuts, lowered the vehicle so that all the wheels where *just* touching the ground and I retorqued all wheels using a torque wrench to spec (118ft-lbs) and my vibration was gone after that. I'm guessing the PO (which only serviced his car at the dealer) didnt get the wheels torqued properly.

    Hope this helps...
