  1. A/C ECON light stuck on

    mikrt posted a topic in Audi A4 (B7) Forum
    Bought my A4 (B7) 2008 privately yesterday morning, and didn't notice till last night that the ECON is on all the time. After a quick google it seems likely cause/s can be faulty A/C thrust pressure sensor and/or low level gas (either lost over time or due to leak).Don't want to buy sensor (and remove bumper etc) if not needed, so I intend just regassing first to see if that fixes it.My question is, can the sensor be removed with system under pressure? Or will I lose all the fresh gas (and cash)?Intuition tells me it's not a good idea, but there are write ups online that say it can be done.Thanks in advance
