Got my car back after having a replacement engine and recon turbo, drove away fine then the speedo started dancing, and the fuel guage too. Cruise control now no longer activates. Had a read and i dont want to accept that the ecu or cluster has spiked with battery connections etc, the earth under the battery was not disturbed apparently. Just got back from adapting a new set of clocks in a mk4 golf, so didnt fancy getting my vcds out again lol. Any suggestions on what to test and look for before i get off my backside and have a look!?
