I cant send you a PM. You can find me as Hefje on www.skodaforum.nl

Hi, Did you format the SD card before you put the data on it? I still haven't succeeded. I did manage to do regular MIB updates with a USB C stick

Why this upgrade? (I'll post some more pictures of the process today)I drive a Skoda Superb Combi 1.4 iV PHEV Sportline (MQB platform), and while it's a comfortable cruiser, I always felt the stock 288 mm brakes were underwhelming, especially during emergency braking. As a volunteer firefighter, I sometimes need to get to the station quickly. I found the stopping power to be insufficient for such a heavy car (1.8 tons), I also own a 2004 Audi RS6 C5, which has 8-piston Brembo front brakes — and the difference is night and day. While the RS6 is more powerful and performance-focused, it made me realize just how undersized the brakes on the Superb iV are, especially when you need to stop hard from higher speeds. That’s what motivated me to upgrade to a proper 340 mm OEM front brake setup, as found on GTI/Cupra models. so I upgraded to a 340 mm front brake setup. Similar to what’s used on Golf GTI / Cupra Leon / Golf GTE. MQB(Evo) platform I also installed: Hardrace rear sway bar DCC module tweak greatly improved braking and handling stability. Eibach Pro kit I sourced all parts from a scrapyard, except for the dust shields, which I ordered new from the dealer. That makes this a budget-friendly OEM-style upgrade — not a fancy aftermarket setup, but a factory-matching improvement that fits perfectly on the MQB(EVO)-based Superb. Good donor cars to look for: Golf 7 GTI Cupra Leon (5F or KLCF) Golf GTE / Octavia RS / Cupra Formentor Most of these use the exact FN3 caliper with 340 mm front discs.

Raise the car and remove the wheel Remove the old caliper and disc ( You can leave the old caliber hanging on the line until you have the new one in place.) Install the larger dust shield (or trim the old one to fit) Fit the new 340x 30 mm disc Clean the hub and apply copper grease to prevent rust Bolt the caliper carrier in place Torque spec: 200 Nm + 90° angle Mount the brake pads and caliper on the carrier (DIS)Connect the brake hose Keep it upright or temporarily plug it to avoid leaks Bleed the brakes With a helper or transparent hose in fluid Sequence: RR → LR → RF → LF Check for: Leaks, Firm pedal, Fluid level in reservoir Test drive at low speed Verify pedal feel, brake balance, and straight braking
