Hello MA! Today I came back from a few days away from my R53, and wanted to take it out for a spin to run some errands. It had been sitting for a day and a half. I have been driving as I would normally do, getting into some boost and cruising around when the EML/SES lights came on. I did not notice any driving characteristic differences after the lights came on, seems to run normally so far. Any idea of what this P1948 code could be? It's a 2005 with 97k miles on it. 17% pulley, new plugs last year, supercharger oil changed last year, new air filter earlier this year. Just trying to give you guys some background info as I'm not really sure where to look? Thanks!
