Ah, the innate bastardliness of inanimate objects! (and overcharging dealers = Smythe in San Jose) I noticed that MBZ offers a replacement gasket for the gas cap for a few dollars-even cheaper!

The car has 90K on it, so O2 sensors will be changed. If I purchase the Bosch #15738 Universal sensors, I can save her about $160 vs the cost of exact replacements.

Questions: Would there be any effective difference between the Universal and the exacts?

How are the trouble codes erased from memory?
