I have an automatic 1994 C180 (W202). It always starts, it always goes and it always gets me back home again. There are some problems though.
Here are the symptoms:
• It often fails to accelerate and seems to get stuck in one gear. Perhaps this is limp home mode?
• Usually a little bit slow to start. It always starts first time, but I have to crank it for a few seconds.
• It sometimes stalls. I can't find any pattern to this.
• The coolant light vaguely comes on and fades in and out. I have checked the Nissens Denmark radiator coolant and it does look a bit murky, but I don't think it would cause all this. It's not overheating.
Most of this is not as common in the cooler months. Whatever is wrong, it seems to be triggered by heat.
If it has a MAF sensor, I can't find it. There's nothing like that near the air filter.
The battery, alternator and voltage regulator all seem to be working the way they should.
