  1. Water ingress in footwells around centre console

    Afternoon all Apologies in advance for the long read, but as you'll see, I'm confused . . . . . . so I've found water under the front carpets of the Smart - which from what I've read isn't all that unusual - but what is unusual is how it's dispersed. The majority of the water is around the...

    My 450 CDI has had a replacement turbo, EGR valve and a new exhaust fitted but it is not making any boost whatsoever and I can't figure out why this might be. The actuator seems a bit stiff but apart from that, the car does appear to be running normally but severely lacking in power, meaning ~55mph...

  8. 1984 synthetic engine oil

    Iíve been tidying up a wee bit and found in my shed six litres of synthetic oil from 1984. At that time synthetic oil was rather expensive and I only used this oil for winter.
