After two visits to the dealership for MAF code P0102 they found that the plug/ wire had broken in the connector. After the MAF problem was resolved I was getting a code for the Valve Cam Position Sensor. |
| 136000 mi US $180 |
P0172 code for running rich. I am still chasing it down. Changed spark plugs and added fuel injector cleaner to the gas. Still reads code but light is out. It may be fuel filter/ pump or computer problem. |

turbocharged 260hp 2.0L I4 5-speed manual FWD

| 3000 mi | Cold air duct was rerouted |
| 48000 mi US $5000 |
Fuel system Fuel pump was bad and pumping fuel into the oil Low Coolant light keeps illuminating, no sign of leaks anywhere. Had vehicle up on hoist and no sign. No coolant residue in tailpipe. WTF Replaced engine due to extremely thick oil. Only thing we could find was a problem with the original engine having hairline cracks in the head and block that allowed small amounts of antifreeze into the oil, turning it to sludge. |
| 41000 mi US $26 |
Exhaust valve actuator failed. Repaired in the driveway. |
| 3720 mi | ECM failure. Don't know why or how, probably just defective from the factory. Car threw a CEL and later, after 10 kms it started to sputter and rev at unusual idle levels and it was also in "limp" mode. Threw 9 codes at the dealer; they determined ECM |
| 27280 mi | Mass absolute pressure sensor failure.... new part installed, no recurring problems. |
