before i drive my 997tt i notice an oil under the car it was leak but not sure from where .. it was light black oil so i cheacked the engine oil level and put 1 liter oil ... when i press the gas hard ,, it show in the dash this msg (( tiptronic emergency run )) and the geer never be in 1st geer or 2nd geer !!! i turn the engine off than turn it on ,, everything fine 1st geer 2nd geer fine ... !!!
the oil which leakin is not red its light black !!!! so what is that ??
what do you think
my car is moded .. also with tcu
thanks

 

flash tcu back to stock then test.

 

What level was the engine oil in the on board computer before you added engine oil?

It would be hard to say what is leaking untill it is on a lift for inspection but with error message from TCM to instrument cluster, it could well be a trans leakage/internal failure, color of fluid should be a goldish when clean and fresh. If there is any trans damage, the fluid could certainly turn dark gold or even black plus leaking fluids will mix with road debris and change the color slightly. It could also be coincidence that you have a leakage of some fluid while having a TCM problem- you did say the TCM was upgraded yes? Who did the TCM upgrade?
Get the car to your dealer or prefered independant (have it towed via flatbed if the trans is in safety mode- no reason to risk further damage)

 

thnx for the info

it was seal ... i will change the whole geer oil pump !!!

 

I had a similar problem, the oil was coming from the gearbox where it connects with the transfer box, there was no replacing part from Porsche or Merc so we changed the whole trany luckily it was still under warranty.

After that i had the TCU flashed but no problems from that.

After me there were another 3-4 cases of 996+997 tiptronics with the same problem and all had to replace the Gearbox. Some of them send their gearbox to a German company which rebuilds everything in it and make it strong enough to handle much more power and torque

 

my tuner said that all the geer parts can be replace with benz parts !!! so no need to replace thw whole gearbox
