OK. To cut a long story short. 2006 Cmax 1.6Tdci (90) engine. 2 months since owning and I get car cuts out after starting with warnings of stearing failure and engine fault on the LCD screen. Car will either move very slowly or not at all. Restart car and all is good. Its ittermitant so the car will work fine occasionally. Fault code when I got one was U0155 lost com's with instrument cluster. Checked fuses and wiring into fuse box all ok. Any ideas? Thanks
