Tiptronic Neurtal to Drive Selection Protocol

[racerden]

Being a Los Angeles traffic-a-holic, I adhere to the owners manual suggestion of placing the TIP in neutral for "prolonged periods of traffic situations". My question is there any way to disable the brake switch/shifter interlock system so I can simply revert to placing the A/Trans in neutral while in heavy traffic without the necessity of having to (1) apply the brake then(2)being to engage the gear shifter knob 'engage request' baloney....Basically reverting to old school AT ingage/disengement w/out brake switch in the picture.

Thanks folks

I think I understand what you're asking... I've done an awful lot of reading about Tiptronics in the last few months; opinion on this side of the pond is that you are much better to leave the shift in drive in stop start traffic, so as not to be constantly disengaging and engaging the torque converter (I think) which supposedly causes more wear than leaving it in drive...

Defonately never put it in Park as if someone rear ends you they are likely to break something on your car more so than if it had been alowed to roll forward at impact. The park position having locked the wheels...

I'm not quite sure why they tell you to put it in Neutral and i'm quite happy just to leave mine in drive...

As for your request to disengage the parking paul break light thing, Its basically a safety issue and is probably illegal, and given that you could engage reverse by mistake and immediately roll back if you were on a hill youre bound to be asking for trouble!

Its set up like that for a reason...

I'd leave well alone, and if you dont like doing what the book says (which I've never done anyway!) just leave it in drive! :)

Thanks, i appreciate your input. FYI, our car's are very simular appearing.

Black was number 1 on my list of requirements!

Whilst we're on the subject, I'm trying to discover the cause of a start glitch on mine which has baffled everyone so far... Can I therefore ask if it is normal to be able to move the shift lever from Drive to Neutral without touching the brake and whilst moving forward or stationary? Also I appear to be able to move the shift lever from Reverse to Neutral without applying the brakes... Is this common, or a fault?

I will say though that you can't move it from Neutral into Drive or Reverse without then having you're foot on the brake... I'm confused!

Also, the gear indicator lights on the dash change in drive about two seconds before the actual gear moves... Is that normal too? (First time owner)

The start glitch I mention is detailed on another post and the symptoms may be related but I just don't know... Anyone got any theories?

Possibly related start glitch can be found here

Gus; What I've discovered is yes, you can move the shifter from N to D as long as the car is moving and the brake pedal hasn't been depressed. Once you come to a stop (like traffic) you can slip it into N however, the brake pedal must be depressed to get it back into D. That's my gripe. On the Tip shift indicator lights, yes they are v-e-r-y slow.

Yea, now I fully understand your gripe, and would still definitely advise you to save yourself a lot of hassle and just leave it in drive like everyone else probably does.

However can you just confirm that you can go from Drive to Neutral and Reverse to neutral (whilst rolling and no brake depression) as well as go from Neutral to drive as you say!

After thinking about this for a while I'm guessing that the above is a big must otherwise you would never be able to get the car into (freewheeling) neutral allowing you to tow the vehicle in the event of a breakdown and no power!

And it is the gear change that lags behind the lights (by about 2 seconds) not the other way around, right?

Appologies for repeating myself I just want to be sure, the Porsche Parranoia is affecting me quite a lot this week, now then, where's that bottle of red wine :thumbup: (It's early evening over here by the way!)

Definately the enablement of accessing R points at a defect. No way can I access R unless I'm stopped, have my foot on the brake and depress the lockout feature on the shifter. As for the Tip's sluggishness, yup it's slow. I've researched our forums and other resources trying to see if there's something out there (aftermarket programer, etc) that will at least get the shift speed into something acceptable...there isn't. It's my understanding that's another reason Porsche went to the PDK. One last note, I finally had the opportunity to track my car at my last race (I road race a NASCAR style car) and if you just leave the car in Drive, the yaw/pitch sensors, trans adapts, brake app sensors and all the other goodies will actually do a pretty good job. Using the steering wheel buttons doesn't cut it at all.

Hope it helps, take care Gus.

Thanks Den, on reflection i'm pretty sure it wont let me go into reverse from neutral, (I didnt try that because I was afraid of forcing something, it seems alien to go from N to R without my foot on the brake in any instance! Habit I guess!)

My point was that you could get into N from D or R without the brake depressed.

That alone was what i wasn't sure about...

Thanks a million for all your help,

kingd regards
