Hi can anyone help me . I have a e46 2001 318i touring. Yesterday when i was out on the car the "yellow warning light came on " it said on hand book Exhaust emission values!.. I had the camshaft sensor and the lamba sensor changed about 5 year ago. the car seems to drive ok but i dont want to take any chances .
ps when i start the engine first you would think that the exhaust has got a "LEAK". Then within seconds its back to its normal self . Is it back to MY BMW dealer or can somebody help ?
