  1. Thanks Loren, assuming the tests are ok and the plunger is stuck/damaged does that mean that the cylinder is not working? Would you think that it's a serious enough problem to trigger the check engine light? My check engine light has stayed off. Here's a screenshot of the durametric screen. Jason
  2. My car just had a top end rebuild ('95 C4, 6speed, 93k miles on the clock) and a Durametric scan revealed the following fault codes: 49 Unknown DTC 53 Injector Valve Cylinder 3 Ironically, the wrench who did the top end (35 years air-cooled experience) noted that the wiring harness needed to be replaced again, even though the original harness was replaced under the recall several years ago. He showed me the insulation that had started to bubble/melt again. As part of the top end, just about every "while you're in there" item was replaced (plug wires, gaskets, etc, etc...) These faults were not thrown prior to the top end rebuild. What does a "Code 53" fault mean??? Thanks in advance, Jason
