Heater And Gauge Problem

8 posts in this topic

hi all,

i have two problems the first is after a mile or so i loose my mph reading on the dashboard, then a little while after i loose my digital milage reading, after this everytime i change gear it sounds like im riding the clutch, until ive turned off the ignition for a few hours then its fine for while and the process starts again, i think it could be the speedo sensor, am i right?

the second is my heater blows cold air but the temp gauge is reading normal and when the above problem happens the temp gauge rises instantly to just under the red but still without hot air coming through, but when the above problem doesnt happen i do get hot air, could this be caused by the thermostat?

please help winter is here and its bleeding cold in the mornings,

many thanks.

They should do it for free. They updated my CMAX for free and also explain to them the problems that has been happening.

Normally its the diagnostics fee, so about £60 + VAT or thereabouts.
