Both the odometer and trip meter on my W126 300SE are rolling 3x faster as they should. I noticed it after I did an oil change, could it be related, cable damaged when I changed the oil filter?

6 months ago I repaired the trip meter, the gear was shot and replaced it with a new gear I bought from eBay. Worked fine and according to the GPS on my phone it was running accurate.

Thanks.
