Default Please Help ME!!!!!!!

hey guys, new to the audi world, just purchased a 2002 a4 quattro 1.8t 5spd with 182,000kms. I love the car and want to do everything i can to keep it. but its causing me some headaches.

Yesterday, the car wouldn't start in the morning(it was about 2 degrees celcius) it cranked, but did not want to fire. So after about 5 minutes of cranking it over, I let it sit for 15 minutes. When I cranked it again, it fired, but was really rough. Once the engine was warm I tried to rev past 4000rpm while in gear and it would not let me go past 4000rpm, it felt like it redlined there.

That same morning I brought it to a local vw/audi shop and had them diagnose the CEL that had been on since I bought the car last week. It pulled up the following 11 faults;

116825 - EVAP Emission Control Sys: Incorrect flow
P0441 - 001 - upper limit exceeded - Intermittent

116840 - EVAP System:Very small leak detected
P0456 - 002 - Lower Limit Exceeded - MIL ON

16804 - Catalyst System; Bank 1 : Efficiency Below Threshold
P0420 - 002 - Lower Limit Exceeded - Intermittent

17544 - Fuel Trim: Bank 1 (Add) :System too Lean
P1136 - 001 - Upper Limit Exceeded - MIL ON

16706 - Engine Speed Sensor G28) : No Signal
P0332 - 004 - No signal/Communication - Intermittent

16684 - Random/Multiple Misfire Detected
P0300 - 008 - Implausible Signal - Intermittent

16685 - Cylinder 1 Misfire Detected
P0301 - 008 - Implausible Signal - Intermittent

It had the same faults for all cylinders as the one above ^

16705 - Engine Speed Sensor (G28): Implausible signal
P0321 - 008 - Implausible signal


They cleared the CEL and the 4000rpm limiter went away. That same night I went to go start the car and the immobilizer would not let me start it. So I left the key in the ignition for 10 minutes exactly and at the 10th minute the immobilizer light turned off and i was able to start my car and drive, but the 4000rpm rev limiter was back as well as the CEL. PLEASE HELP!!!

You have some serious issues going on, I mean serious because it seems to be multiple issues. Its seems that you need to start with the engine speed sensor first.
Then the misfires, then the evap problem
