I bought this 2019 GLC63s last week from a MB dealer.
The original owner made many upgrades to the car and I've been trying to figure out exactly what was done.
Here's what I've found so far:
Fully wrapped in PPF (don't know if Xpel or 3m) Entire car wrapped.
Custom installed AL Priority laser jammer system (front and rear)
Custom installed Escort Max CI International Radar detector system with mid-city engineering OEM integration
Renntech HSM (Handheld suspension module)
Renntech Blow off valve adapter
Renntech exhaust valve module
Here's what I'm trying to figure out:
Renntech confirmed to me that an ecu upgrade Hand held tuner was sold for this car.... I don't know if it is tuned currently or not...
There is a Micro SD card in a tiny bag with the last 5 digits of the vin# printed on it.
Renntech said it's not from them, It has a folder titled "the vin#" containing LOG files and other .SCR files
I've inserted this SD card into the car, but it doesn't recognize any files.
What is this???
I'd love to find the original owner to find out what else may have been done to the car.
Anyone have an idea what this SD card is?
