ML 430
Help please ML430

Hi, I'm the owner of a 2001 mercedes ML430 and i was having no issues with my car until about 8 months after purchase. I began to notice after one day of interstate driving that my RPMs were unusually high. As the days went on I felt as if my car didn't have as much horsepower or giddy up as it did before. I looked up the ml430's top gear(5th) and I think my car is staying in 4th and never getting up to 5th. Is there anyway to fix or diagnos what this problem is? My car has 81,000 miles -Thanks

Welcome to the forum.
Yes there is a way. Have your car scanned for codes with a pro level scanner & post the codes
