I have Peugeot 308 2008 36+k on the clock, recently have an oil leak at turbo supply hose, Peugeot at Bowen Hills said there was nothing! But local service found it, I had oil on the garage floor. How much should it cost to fix? They tell to to replace the coolant feed hoses at the same time as they are oil soaked. I am a woman and we, mostly, are lied to therefore don't trust mechanics. I’m in Brisbane, can anyone recommend a reliable mechanic?
