johnsongd; Crossfire convertible roadster? Limited or SRT6

"My mechanic did not have a compatible scanner and recommended a local European car mechanic to find out what the codes were causing the BAS/ESP light to be on. He's not reading any error codes when scanned yet the BAS/ESP light is on." ~ ~ Who is he? Your regular mechanic, or the European car mechanic?

You can not allow the scan tool to do its normal initiation. You must manually put in Model/ frame 170 and then SLK 320 or SLK 32, depending on the car you have. The Crossfire will scan as a Mercedes 2003 SLK
