Hi Guys!

I've had a 2004 CTT but i'm having problems install the renntech lowering modular. I can't lower the car after the installing process. I don't know if i had done anything wrong but is there anyone had use the renntech modular on a CTT? What's the right installing process or what should i do after the modular had plug in?

Thank you.

i think there is a need for software modification on the car

 

I don't think so!

 

i know that these modules are not just plug and play. Some mods are needed on computer, let the other experienced guys talk

 

Not sure about the Renntech.....


But i know that the Techart requires the parameters for the air suspension to be adjusted after the unit is installed.....


Your module should have come with detailed instructions though.....

 

Renntech user manual didn't mention need to use anything else. After install the modular there is a couple step need to follow to adjust the air suspenion and i think it's for reset the ecu. I follow the steps but just can't lower the car so i just wondering if i do anything wrong on the steps.
