We are currently running a 5 - 6 business day turnaround on repairs once we receive your unit and please note our September closure when sending your unit in for servicing. Please be advised: We will be closed for the entire month of September. During this time you can still send your unit in to get in line for servicing once we re-open on October 1st. 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.
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.
