Title: P0321 fault code and oil pressure light!!!!
Post by: stevie040 on June 28, 2015, 07:16:35 pm

Hi need some advice. The gti had been running great with no issues. Over the last few weeks it's been feeling a bit sluggish compares to before. So got myself a. Ode scanner and went out for some runs. So booted it in second get to approx 5k rpm and it stutters and the rev counter cuts back. No codes. Do this again this time the rev counter goes crazy and eventually sits at 0 with a big red stop showing on the computer with oil pressure lift engine management light etc. one code now pending p0321.

Firstly engine was turned off straight away but when starting back up no warning lights etc. any ideas what this could? And is it a coincidence or could the sluggish feeling be related

I see this hasn't been concluded...but I will leave this for the P0321 code.

This happened on another car. It started and ran, but would kick itself into Limp in the 3k rpm range. It coded P0321.
 
What was done in trying to resolve this; G28 Sensor was replaced and still the code. Voltage checked and found OK. Pulled the oil pan and found this;
