Lightbulb Speedometer not working & power steering issue

Hi all!

Hoping for a bit of advice.

A week or so ago, upon starting up my car, the power steering warning light came on and the speedometer has stopped working. On top of this, all of the 'trip' details on MPG etc have been wiped leaving only total mileage showing.

The rest of the dash seems to be working fine.

I have checked fuses in glove box fuse box and all filaments seem in good shape.

I don't suppose anyone can shed some light on a potential fix or what might be causing the problem? I don't think the power steering & speedometer are necessarily related how ever it's strange that the problems came about at exactly the same time.

Thanks !

First thing to check is your battery, battery connections and "earth" leads between battery negative, chassis and engine.
Other than these known issues you would need to get decent diagnostic software (Multiecuscan or AlfaOBD) on the car and check / reset the fault codes. Is the power steering working OK? if it is it may be a CANBUS or ECU fault.
B.T.W driving with a faulty speedo is an offence (unless you are going to a garage or MOT station). If you have a GPS you could use that for now. If you do get stopped for speeding don't use the faulty speedo as an excuse, it might get you an extra ticket.

+1 for checking earths. My daughter's car did exactly the same thing. Earth lead LOOKED fine, with good connections to the chassis and gearbox, but inside the insulation around the crimped terminal that goes on to the body earth (and completely invisible to the naked eye), the copper was just green mush.
