Cool Sign of Death

Pulled out my ML550 yesterday to go pick up a Nest thermostat and all of a sudden my "check engine" light turns on . Not too happy about this. Even though the lowes I went to was 3 miles away I got concerned. Didn't take it over 2k RPM on the way home.

Heading to the dealership this afternoon..I'll let everyone know what they find.

Lol didn't notice that...but its now fixed! So they ran hooked up the computer to the car yesterday afternoon and it did a fault code did appear...but doesn't say exactly where...is this possible?

The tech said it could be a cylinder mis-fire..? I told him the car was driving very different than usual. Anyway, i took it back and will be dropping it off Wednesday to have it stay with the tech for a few days, meanwhile ill be getting a 2014 E-class. Thats why i didn't leave the car at the dealership yesterday, because they didn't have the new loaner back yet.

Ill post as soon as i get an update from the tech!

Nanook, how is the RennTech tune in your ML? Did it noticeably wake up the beast?

It is like a couple plug wires were put back on..throttle response is the biggest change and power delivery is so linear now..this vehicle is deceivingly fast..no hoopla / big revs / big shifting..none of that..just..braaap braaap braaap and you're into triple digits...very quick and remember my other car is a ZR1..now there is noise and wheel spinning drama. This summer I'll have to run the two..say 40-130 will be an interesting test as the ZR1 can't get traction from a start and the ML needs a roll to get deep into boost...blower versus turbo's
