230SLK Stops While Driving

I have a 2000 230 SLK that at times just shuts off while driving on highway (55-65mph) then takes between 1-15 min to start again. ALSO sometimes won't start after sitting 10 min to overnight. So far the shop (they contacted MB dealer in VA Bch to ask of them also) doesn't have any idea, no definitative reading on the diagonistic test. What's up with it?!! PLEASE help!

Had it replaced by my mechanic. {Not Mercedes}. Cured the problem. I know there is a big difference in model yrs, but try it anyway. My mechanic told me that this is a frequent problem with MB"s. Good Luck.; ▶ Reply to This

So tomorow im going to run it into a local import mechanic here and have it serviced. It shows a type I service due in 5000 miles. on the computer. but i am having the brake fluid change , cabin filter. oil , so at least i will know where i am at
I know this doesnt related to your problem, Ill ask the technican tomorow if he has any ideas what could be causing your problem, and post back
the car only has 35 k on it. runs like a top kompresor; ▶ Reply to This

It is a common fault on most mercedes models and causes the exact faults you have described.
You can either just replace it and test the car (not a big job)
or get your garage to put a scope on it and test the sensor first.; ▶ Reply to This
