Check engine light. . .

[Ag4.8]

Scheduled oil change as directed by iDrive. Got the check engine light the day before the appt. They called to tell me the cause is the "fuel vapor pump sensor" near the fuel tank. They are ordering it and will replace on Fri. I have done a search and never heard of this as a cause.

Has anyone experienced this?

Also. They SA noted that my iDrive said oil service due in 700 miles, but my key said 4500 miles. I had the oil changed at the dealer at 7500 miles (and today at 13000.

There is a pump that tests the fuel pressure sensor... fairly common as these age. The are also called leak diagnostic pumps... here is a reference (different model, but you get the idea)

Not sure why there would be a discrepancy with the key and the car...I thought they synced up when you start the car. Did you give them an old key that had not been used? Or maybe used one key at the last visit and a different one now?

Yeah that sounds like the part they are replacing. Only have 13000 miles though. Oh well. . . .

I only use one key. Other is in a drawer at home as the wife has no interest in driving it.

Had mine trigger CEL for that part at around 30k. Parts ordered and replaced within a few days.

I still have 21000 miles until next oil change, that is after driving almost 4000 miles since last oil change. Asked my dealer to reset it because whoever reseted the last time, obviously did it wrong. When I got my car back, it still had 21000 miles and said "CBS takes care of milage until next oil change" on the invoice. You would think, common sense in any mechanic would say "25000 miles per oil change" doesn't sound right. Obviously not the case with some. I am going to have to get that taken cared of on my next visit.
