R320 suddendly died at stop sign


If intermittent, I would suspect the pump. Maybe they want you to drive until it fails and they can be sure.
Here is a synopsis of the invoice:
ran 541011 & 541012 short tests, perform 139 WM08, ran 075701 fuel pump delivery 139 wm08
28411 NO PROBLEM FOUND. connected SDS and ran short test found code 2017-001 rail pressure monitoring via volume control valve. rail pressure to low. SDS advised to replace quanity control valve. tested amperage of low pressure tank fuel pump.running between 7 and 9.5 amps. spec is 9-14 amp. opended TAC case. advised to continue monitoring fuel pump. all ok at this time.
just got back fro driving it 45 miles, ran ok. computer showed average of 25.9 MPG.
