my bmw had lost 3 1/2 quarts of oil and was ticking loudly
Hi, I brought my 2004 330i into the shop today as it was ticking loudly. The
check engine light had been on for three months. I had it checked before I
left CA for MN and the codes were PO171 an dPO 174. The mechanic
cleaned but did not change the air sensor so the Check Engine Light
remained on. Yesterday, there was a loud ticking, and the lower gears were
dragging as if there were a strong wind when it was a calm day. When I
brought it in for a diagnostic, the engine was missing 3 1/2 quarts of oil.
Once we topped off the oil, and I drove off, the ticking stopped. In the past,
the oil light always came on when it was a quart low, and I would top it off.
Thoughts? Thanks in advance!
