My name is ***** ***** I am a professional here at Just Answer. I noticed that your question had not received a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
My info is somewhat limited on your model here but I had seen no one else has responded and would like to see if I can help here.If at any time you feel that I cannot help with this please let me know.
If there is excess carbon build up in the engine or valve this may be causing this issue here as well as possible fault with excess back pressure in the exhaust system due to a restricted exhaust component.I would have the fuel gauge issues corrected here and the carbon cleaned to see if this corrects the egr fault here as well as the exhaust tested/checked for any restrictions possibly.
As for the fuel gauge issue in allot of cases I find the fuel level sensor in the fuel tank is the cause not sending the correct signal to allow the gauge to operate properly.If you know for sure you have no power or signal (as some gauges do not use a power signal they use resistance instead) I would have the wiring checked leading to the gauge to see if any wiring issues are found needing repaired.

O.k.,the back pressure test is a good idea to see if a fault is found.I would also trace and check the wiring to the fuel sender to see if any wiring issues are found.
