Mercedes CLK Diagnostic Trouble Codes
The first section is hidden codes you can read from
the AC unit. The second section are the
power train trouble codes. The third section is the transmission trouble
codes. And finally, the last section
discusses the ODB port. The ODB reading
I use is from Pepper and costs only a couple of hundred dollars.
If you hold down the restore button on the climate control for approximately five seconds a series of numbers will show up.
