My 2008 Mini s with 51 K miles, has been in to the dealer over the last 5 years three times to have the injectors cleaned ( twice with solvent and once with a walnut shell sandblaster. Just three weeks ago my mini started to run very rough, lose power, etc. One of the cylinders had no compression and a burnt valve had to be replaced. Out of warranty, have been told that this generation of Mini S has a design flaw with the injectors and this problem is likely to be ongoing. My mechanic has taken photos of all the parts that were replaced, we will be addressing Mini USA for some type of response. I really enjoy my mini, but have been told by several mechanics to get rid of it while its still running good. anyone else experienced a similar problem, any suggestions? With just over 51K this type of problem shouldn't be occurring....Help!
