Hello, this is my first time using this forum.I have read articles refering to the bosch hammer and realized it is a rare and expensive item.My question is, has anyone used the durametric code reader, and if so, is it a worth while investment.I should mention , I bought my first porsche last fall,It has lots of issues,but I love it.Presently I have the engine removed to repair some oil leaks, and tune it up.It was a little over whelming at first, but with forums like this, I am becoming more at ease, so thanks for all the great articels ,it is much appriciated.
