Hello all,
I was wondering if anyone could explain camshaft self-adaptation diagnostics to me please? The Clk 280 is running very well having put a new MAF and plugs on, but i got to looking at the camshaft self-adaptation figures whilst at idle and noticed a small discrepancy between them. My thought is that it is normal at 80+k miles for the ecu to have had to compensate for wear, but why has one camshaft not needed to be retarded at all? Is that normal? Have I mis-appropriated the importance of the numbers? Readout from icarsoft MB v2 below. Thanks, P
Ps. No CEL and I’m not concerned, just interested. I’m very much a beginner but slowly gaining more experience. I think I’ve conquered fuel trims at least.
675 Adaptation of Camshaft Position Right Exhaust -1.25°
676 Adaptation of Camshaft Position Left Exhaust. - 1.50°
677 Adaptation of Camshaft Position Right Intake. - 1.25°
678 Adaptation of Camshaft Position Left Intake 0°
