A couple months ago I had an isolated event where I received a "gear not engaged" warning or something similar after shifting into reverse (the car was engaged in reverse and was moving) with the "4th" gear light flashing. Only happened that one time.

Now, on the drive into work today, I was stopped at a light with the transmission in 2nd. When I pushed the accelerator, the transmission acted as though it was in neutral (engine revved, but no car movement). Gear indicatior said "2". I shifted into "N", then back to "D", and all was normal again.

I made an appointment with my local dealer, but I am am hoping to get some input as to what might be the problem just in case the dealer has a tough time figuring it out. 99firehawk suggested a cable adjustment after the reverse incident (thank you Brad), and I'm thinking this could be a Tiptronic control module (computer) issue for the 2nd gear-neutral thing. Any ideas?

if it was a hard fault something electrical you would most likey have a set of flashing tip indicator lights and maybe a check engine liight
did you get the lingae adjusted?

Thanks Brad. I was waiting for something else to happen before I take the car in for service (just a little hassle in bringing the car in for service) -- and this incident is just that something. No flashing "4" indicator light this time. Sounds like both incidents may be related, since the first time the car was in "R" but it thought it wasn't, and this time it thought it was in "D" but it was actually in neutral. I'll let you know what they do. Thanks for the input.

We have an '03 with the D and 4 Flashing. Anyone know what might cause that?

THAT MEANS THERES A FAULT

We get a code 10 with our PST2 but noone knows what it means.

P1702 (DTC 10) Supply voltage of valves
Control unit in limp-home mode, minimum cycle initiated

Potential Causes:
Short circuit to B+/ground or open circuit
Tiptronic control module faulty

alpha1 - just curious, how many miles on your car?

smith_motorworks

Loren -- Thanks. Where do you get your code information from?

Steven C.

Probably his great website?

Loren

We do try to put a lot of info online (at my site) but these G100 Tip codes I haven't got around to yet.
They come from the Tiptronic G100 Diagnosis section of the service manual.

was the car jump started recently?

Tippy -- About 7k miles. I took the car in for service. They found no codes, did nothing. I then asked them about adjusting the linkage, as Brad suggested (thanks again, Brad). It only happened twice over many months, and has been OK since.

smith was the car jumped recenlty or have a dead battery?

Tippy

Found the problem, you need to drive it more, it forgot that it was a transmission. Naw, all jokes aside, hopefully the Techs will get it squared away. By the way, I have 93k miles on mine without issue, knock on wood.
