You don`t say what fault codes the garage had registered but have they checked the turbo waste gate for seizure? Common problem on these. Also play in turbo impeller,splits/cracks in intake system/intercooler, if they are struggling to read codes then check the ECU at the bulkhead for water ingress-another common problem, rainwater drips on top of it.
