Greetings flat six fans !!! I have an interesting problem, and before I start pulling parts and panels I thought I would pass it by the group.. My car is a 2002 cabriolet with a Fabspeed exhaust, 101763 miles, 30,000 of are mine. The car is a weekend driver, except for me it is an 85 mph and 900 mile weekend.

I use a Foxwell NT510 OBD scanner which has worked very well at helping me get codes and affect repairs.

2 weeks ago I disconnected the battery to remove it and clean the front drains, as well as install a 2-din Kenwood. I snaked the A/C plugs down the back of the center console with not much problem.

Except.......after putting everything back; the car starts just fine, but I no longer have any throttle response, the pedal is dead. The car will run through the warm up cycle all the way to operating temp, and will shift into gear, reverse and forward gears ( idle speed) There are no error codes on the dash, and the car is not in limp mode.

When i check the diagnostics, the tiptronic transmission does not show up, no communication, it's not there so i can't even get fault codes.

Do TCU's die like that ? or did i break a wire fishing the A/C cables down the back of the console ?

Please advise, Steve G

Un-install your Kenwood. Sounds like you have shorted your CANbus .It is a twisted pair of wires that runs from radio,instrument cluster, a/c,DME, TCU ect. It is the communication network between components.

Also check that you didn't accidentally disconnect your accelerator pedal, someone did this just the other day, they found the wire plug , but couldn't find where it went (it went behind the accelerator pedal) .lol

I agree - sounds like the e-gas pedal is disconnected. Have you tried the throttle adaptation procedure since disconnecting the battery? (Ignition on for 60 seconds without touching throttle, then 10 seconds off, then start the car.)
