275D - P0172:
Bank 1 oxygen sensor limit position fault

1. Check fuel system for leaks, initiate test routine as indicated
2. Check exhaust system for leaks
3. Check intake system for leaks and correct operation
4. Read out oxygen sensor diagnostic data, perform both oxygen sensor test routines as indicated.

275E - P0175:
Bank 2 oxygen sensor limit position fault

Same thing as the other error but for the other oxygen sensor.

Somethings going on relating to the o2 sensors.

If you don't get it fixed by September, bring the car to me when I'm back in the US and I'll have a look.

Good luck
