hello all,
I have a 2001 disco 2 se7 with alittle over 200k miles. my problem is the cruise control only functions properly when the radio is turned off. when the radio is on, the CC seems like to wants to work but then will surge the speed and then stop. I already replaced the hoses and looked at all the other parts that go to the CC system. any ideas would be appreciated

 

I know, this is an old post. If you are still here, did you ever find the problem? I am have the exact same issue.

 

Unfortunately not. I was hoping someone on here would be able to point me in the right direction, but it seems people only know how to diagnose blown head gaskets or tell people to refer to the RAVE manual

 

Been searching here. Came across this post...
Not sure if it's a lead. Double checked ans cruise control and radio do NOT share a fuse. Thinking it's a voltage thing. That when cruise control and radio are on they can do OK until the CC accelerates the car, maybe asking for more amps or volts then it can get, and shuts down. Just a theory.
Do you have any LED interior light bulbs? I do.

 

That's interesting, I do intend on replacing the stock radio for something alittle more hip. LED lights are also something I am thinking about doing because my clock and temp control bulbs are burnt out. Have you had any problems?
