Throttle Body

📎 No Acceleration, P2102 P2111 Throttle Valve | Blocked Throttle Plate | 2014 Mercedes CLS 250




  • Need SCN coding to program new TCM/Valve Body/ Electric Plate.
    When the new electrics plate /control unit/valve body is fitted to the transmission you must carry out the full initial start up process straight away. If the vehicle is started and driven without the initial start up process fully completed, the vehicle will start and drive in emergency mode only. The control unit will be locked out, and it will not be possible to complete initial start up of the electric plate/valve body/ ECU. THIS WILL RENDER THE CONTROL UNIT UNSERVICEABLE.

📝 Parktronic Diagnosis | Faulty Parking Sensor | 2012 Mercedes GL 450
  • A client has bought a few aftermarket front sensors from the ebay to fix the parktronic system malfunction messages.
    Front bumper has 6 sensors for parktronic.
    Star Diagnosis showed that 3 sensors on the right side of the bumper have faulty communication.
    When we unplugged one of those, scanner showed a different code about connector disconnected on that sensor.
    When we swapped known good sensor from the left side with the one that showed a trouble code, DTC for that suspected sensor also followed to the left side, leaving only 2 DTCs for the right side sensors.
    At this point we suspected that all 3 ebay sensors were bad.
    But here is something that I learned that I didn’t expect:
    Customer still had original sensors for the right side that he originally thought needed replacement, because the right side of the bumper was damaged. Now, we decided to try and put original sensors back in place of ebay ones. After swapping 2 of them, 3 DTC’s still remained.
    But when we swapped the last one, even with having those 2 ebay sensors connected back, all 3 codes disappeared.
    Looks like even one faulty sensor can trigger “false” codes for the other sensors as well.
