ATTENTION: We are currently averaging a 2 to 3 business day turn-a-round on repairs after we receive your unit. Please retain a copy of your tracking number when shipping your unit in to us for repairs since we do not send out notifications of your packages arrival. We will be closed between Christmas Eve and and New Year but you can still send your units in during this time for when we resume repairs once again on January 2nd.
Occasionally the oil sender unit will short out internally and cause the needle to peg out but return to 0 when the key is turned off.
If you suspect a faulty sender, unplug the sender and inspect for oil leakage and monitor the gauge's reaction with it unplugged to see if you get the same reaction.
