Or this printing could be SCQ4C or less likely SC04C, and perhaps RMAA0513. But the real question is - can you help identify the 8 pin IC in the middle of the board? It's marked with embossed characters A916 and printed characters (hard to read) which I think are SCO4C in one line and RNAA0513 in a second row. The one next to it is A7s 47, with the s underlined. I've kept the top part, but it has no markings that I can see. I need to figure out what to replace it with, having assumed it won't work. One transistor (near the top edge of the board as pictured) came apart while peeling the silicon away, after much digging with various picking tools. Here is a closer pic of the board, made by Helbako in Romania.

The inner loop would remain stable at around 600 ohm. It would increase from around 200 ohm up to around 1400 ohm. The outer loop was reactive to having pressure applied from my daughter's hands. With the sensor out of the car and cleaned for inspection I observed that the black and white traces forming the pressure(?) sensing mat were working.

Before removing it from the seat (big job) and stripping away the silicon(?) that the board was encased within (bigger job) I observed open circuits between the brown (ground), red and white wires. The vehicle's On Board Diagnostics are clearly pointing to it being faulty. Could I ask for your help please with identifying a few components on the circuit board for the pictured seat occupancy sensor mat, from my BMW 120i.
