SLK 1999 230
HI ,

I am a new member and have a problem with my SLK. I had not used it for a few months and it now will not start, turnover or anything.
I had a scan with my Icarsoft MB2 and the error comes up as Y66/1 Valve defective. I have checked the voltage to the solenoid and it OK
I have tried 12v to the solenoid direct and no sound no movement. I assume that if the solenoid do not engage then the car will not start.
I had bypassed and wired the starter direct to test it and it turns over no problem. Does any one know if you can replace the solenoid it has
a Mercedes part number on it A1402770298. I phoned my local Mercedes parts and they say it no longer listed as the car too old. Its made
by Binder.

Any advice would be appreciated. Thanks in advance.

Welcome from a fellow R170 owner.
I'd try tapping the solenoid whilst powered up. You never know and the impact might just jerk it into action.
