W208 DAS troubleshooting
In your model year 2001, two diagnostic ports are featured. The engine uses the OBDII 16-Pins port. Your best bet is to use Mercedes DAS to access live troubleshooting reports.
You can go over all the basics until you really need to see what's bugging your computers...
Here are the factory docs W208 V8 4.3L you may find helpful.

2002 230K
Have and post similar problem 2002 C230K manual mechanic drives car no codes and can't reproduce- second time- last time there was a 'thunderstorm type- odor, first time none. First time check engine and some sensor reset, second time no check engine. He's been VERY fair first time no charge said nothing to charge me for. Thinking to ask him to clean out fuel injectors as a precaution, vehicle is 24 yo and no garage, parked driveway in ocean environment.Thoughts on fuel injectors or anything that could account for sudden loss of acceleration- to coast to side of the road.
Seems to occur after highway speed then about 8 miles into negotiating 25-35 mp zone

What is your fuel pressure?

Those early 2000s gas pedals are notorious for failing. Not sure if it would throw a code. You would need DAS or an equivalent scanner to check.
(NOTE: XENTRY replaced DAS. But if you have XENTRY, I think DAS is built in.)

specific setup necessary
Nowadays through OBDII DLC, we are used to access all remote modules through CAN-Bus D into Gateways to CAN-B; C; E. These CAN operations seems simple thanks to standard serial protocols.
Gateways are sleepless 24x7 modules that benefit Reboot to restore processing speed. The Central Gateway (CGW) can quietly impacts every module: engine + tranny without any obvious code.
