that appears to be a camshaft position sensor performance code. you can start by checking to see if the sensor is working properly, re-check and make sure that the harness is ok by checking the resistance through the harness if all looks well there make sure the computer has the latest software on it by having it scanned at your local dealer. also you can check the reluctor wheel on the camshaft for damage or debris in the way of the sensor.
hope this helps!

You have a security issue now. Most likely you will have to get a scanner to do a relearn unless you can find a manual way to do it. Try putting the key in, turn on and wait 30 minutes. It may need time to learn the key.

A code P0430 may mean that one or more of the following has happened:
First, inspect for exhaust leaks.
Next step is to measure the voltage at the oxygen sensor on Bank 2. In fact, it would be a good idea to test each oxygen O2 sensor while you're at it.
One thing to note is that many vehicle manufacturers offer a longer warranty on emissions-related parts. So if you have a newer car but it's out of it's bumper-to-bumper warranty, there still may be warranty on this type of problem. Many manufacturers give a five year, unlimited mileage warranty on these items. It's worth checking into.

It could just be the fuel injection tips have black tar build up. But, this sounds like the typical, 1980's problem with people who used to put cheap gas in their mercedes. You get gunk buildup in your gas pump. When the car is hot, the gunk expands and you get no gas flow. First try about 4 applications of puting a bottle of good fuel injection cleaning fluids in only half tank gas and let it run almost dry. If you don't see a substantial change, don't even waste your time playing with it trying to clean anything, those are only agrivating band aids on a broken leg. Change the fuel pump! your car should be as good as new.

Do you have any codes for the check eng. light. I have seen the steering angle sensor on your model go bad which could cause the light to go on. The trans slipping could be your vehicle going into limp home mode because of the codes. Without running a quick test it's only a guess.
The problem with your gas indicator is the fuel pump, you will need to replace it. The card on the pump gets ruined from the sulphur in the fuel.
The problem with your lights could be the dimmer switch turned all the way down. Yes believe it or not this has happened.

Testimonial: "Thank you, I will check into what you suggested. The engine runs great with a can of Seafoam. Does this make sense? And I do have some codes."
