Mercedes ECU’s & Common Missfires
We are currently taking a high number of calls whereby customers are experiencing the common miss fire faults indicating coil packs and faulty ECU units. We can repair the ECU units but please understand, once we send it back to you – you MUST change your coil packs (Yes, even if you’ve done so already) because if you fitted new coil packs whilst the faulty ECU was still connected, then the new coil packs would have gotten damaged.
