I am having some issues with my recently bought 325ti auto.
Have had the 'check engine' light come up on my dash twice in the last month.
I took the car the garage for a diagnostics test and the mechanic told me it was showing 'o2 sensor' as the issue.
He cleared the code and told me to come back if it showed again.
2 weeks later it comes on again, take it back to the garage, same code comes up, but this time the mechanic tells me it could be one of many problems, and that the 'o2 sensor' coming up is just a guideline to the source of the problem.
They told me I would be better if getting an electrical mechanic to take a look to try find the exact problem otherwise it could get expensive changing sensor after sensor.
Any one else had this or a similar issue?
