Cruise control problem

Anyone got any idea why my 260e 124 (1989 model petrol, England. 109000miles )series drops out of cruise control? Doesn't seem to like to be engaged a low speeds either, drops out more often. When doing 70mph, will
surge forward first a couple of MPH, engage, and then drop out after 10 minutes.

Electronic controller unit needs to be rebuilt.
See a rebuilder site: http://gdl-online.com/begin.html
Must be others closer to or in the UK.

Not uncommon. The usual fix is to pull out the cruise control amplifier and resolder every joint you can find. This fixes 99% of them.

It's basically how to mend a CC module on the kitchen table.
