Mercedes-Benz MB Repair Kit for Engine Control Unit ECU Bosch ME9.7 M272 M273

Description

This repair kit can be used to repair:
- Oxygen sensor faults
- No communication faults
- Ignition faults
- Throttle faults
- Cooling fan stays on
which are common on the ME9.7 ECUs used on Mercedes-Benz MB with engine M272 and M273.

Included in the kit:
TLE7209-2R driver (throttle faults)
30615 Bosch oxygen sensor driver * 2 (oxygen sensor faults)
30554 Bosch power supply chip (power supply faults)
30521 Bosch ignition chip (ignition faults)
30620 Bosch injector driver * 2 (injection faults and cooling fan always on): on M273 ECUs, there are two chips. On M272, just one. Chips are the same.
220U 50V capacitor (often the root cause due to leakage)

Not all chips may need replacement always, but the kit includes whatever is needed to complete a job on most situations where one or more of the error mentioned above occurs. If other issues are present (e.g. short circuits, damaged PCB), the kit may not be enough. Rather than a complicated repair, you can evaluate to purchase our aftermarket ECUs (M273 link M272 link) in that case.
