hi,
I have a 1999 V 206 2.0L HDI,
I was driving to work this morning doing about 60mph... I slowed down for a corner...... the speedo did not, I arrived at work and turned the ignition off. the speedo sat at 70MPH when i finished work I noticed that the speedo still kind of worked but it thought '70' was '0' so when i was traveling about 30mph it read 100Mph...roughly... I got home and looked into the haynes manual but nothing specific to this problem i went and had another look and discovered that switching the ignition on and off dropped the speedo dial from about 70 MPh down a little to about 62 and kept on turning ignition on and off about ten times until it eventually reached zero....
started car up drove to end of road and when i stoped at the junction the speedo fluctuated and wouldn't go under 30MPh.... so it now thinks 30 is the new zero.. until i go a little faster...
Any ideas anyone? cheers chris
