My 260E lost rapidly power. I was able to start the engine in Parking position but when I switched to Drive, released the brakes and pushed the accelerator pedal the engine dies.
The closest mechanic disconnected EHA valve and I was able to get home. He recommended to run a scan.
Could the EHA replacement help in this situation?
What does this EHA valve do? How to check is it Ok or not?
Thx.
