I took the car in for the MBrace telematics update and have a rattling noise fixed with the instrument cluster. The dealer fixed the instrument cluster rattle but they also fixed an oil leak that involved the replacement of camplugs. Thankfully all this was covered by the CPO extended warranty but the oil leak concerns me because I was told that with the cold weather we have been having that they have seen this often. What concerns me is that with the car driving normally I had no idea I had an oil leak and I could have potentially driven like this for months. I am also concerned about this oil leak situation happening when the weather is really cold -- is this common? How does this happen?

Could someone decode the following segment of the invoice and let me know what the line items entailed? I've never had any such repair in any of my previous cars so I am just trying to understand what is going on with the car and what was done. How much of a repair would this have been if I did not have the warranty? What are these cam plugs? I searched the forum and could not find anything.

Thanks so much!

Expansion plugs were modified to prevent leakage as of JUN08 production new improved plugs were phased into production (260 & 255 in diagram).

Thank you so much! Really appreciate it.

Good to know what it was for. I was afraid this is something I need to look out for during "cold weather"

PS: Do you know what the "Air cleaner" line item refers to?
