Hello,
Really need some help with this. My VW Golf MK4 TDI 1998 developed a problem where the speedo stopped working all together and the fuel gauge wobbles when entering a bend etc. I have had the gear stick sensor replaced and it still does it. A garage has ran a full diagnostics also and everything came up in order.
The rules have now changed as of yesterday for an MOT that now means you must have a working speedo hence why I am now in a panic to get it fixed as its due in April.
One thing I have not done is replace the cluster unit. Now I have seen some vids and looks fairly straight forward to do but I am concerned as I have heard from a garage that the immobiliser has to be reset so I may not be able to do it my self. does anyone know if this is the case or if I could replace the cluster unit my self with no issues??
thanks so much for your help.

Pretty sure you will require VAGCOM to code in the new cluster...

gear stick sensor??
most common cause of failed speedo in a mk4 is the wires coming from the speedo sensor on the gearbox, follow them along the top of the gearbox and they rub through/break. You'll need to take the battery tray out to see it properly
