Hi guys,
As my first post and my first Mercedes, hope someone can give me some guidance on a couple of issues i have been having with my 2003 w209 200.
As the title suggests, I have been experincing a gurggling/bubbling noise when putting my foot down on the gas pedal. I recently left my fog lights on and ended up draining the battery a bit, i had to remove the battery and charge it up, since then i have been running the car occasionally to make sure the battery is still charged. While feathering the engine i staterd hearing a guggling sound from behind the steering column. I took the car out this weekend for a 2 day trip and didnt have any issues. It is not over heating, i didnt notice any air bubbles in the coolant resevoir, and didnt notice the noise while driving. However i ran the engine for a bit last night, and the sound was very audible as i gave it a bit of gas...any ideas??
Second issue. As mentioned previously I dropped the battery charge by leaving the foglights on a couple of weeks ago, but even before that, the car has been very sluggish when starting up..it always starts on first try, but it sounds like a weak battery when it is first cranking over. I have measured the batter with a multimeter, and it isnt loosing the charge. The battery holds steady at well over 12.75v when not in use, 13.9 when running. But that said it seems that it is the original batter so it is well over 15 years old. I have not checked the starter relay nor the fuse yet...
And finally I have a P0120 throttle/pedal position sensor/switch A circuit error showing up on my scanner. The car idles a quite sluggish in gear, but drives fine and is relatively quiet in park& neutral. Can anyone tell me where I should start trying to troubleshoot this error?
Sorry about the wall of text, and thank you for any advice given.
