I have bought a series 1 focus rs with around 37k miles from a reputable dealer of rs's but in less than 1 day the turbo failed. They have replaced the turbo but in only a few hours the turbo has failed again. It looks like a lubrication problem to the turbo to me but I wondered if this was a common thing that points to a bigger issue that I should be afraid of, or is this an unusual thing that has a smaller non serious problem behind it?

Any advice would be appreciated to quash my fears thati am about to have to embark on a road to ruin due to the start on a long list of issues this car may have.

Cheers.
