Hi, I am a connect owner hello everyone

[Drews]

Hi ,got a 2005 connect L230d only had it a week ,all was fine then had loss of power after topping oil up ,turbo intermittent loss was ok at low revs but on motorway wouldn't pull very well seemed about 60 ish top speed as speedometer struck on full speed but drops occasionally not done diagnostics yet just thought I would see if you guys have any ideas as there's no smoke runs ok apart from turbo thanks for any replies in advance
