Took the Speedo out to fit new LEDs bulbs, loosened the 3 screws but didn't remove before I realised the bulbs could be pulled out .
Refitted the Speedo but now at rest Speedo reads 20mph , when driving Speedo works fine but over reads by 20mph at all times
Any ideas what I have done wrong and how to fix
