A3 1.8 T: LMM and ESP (air mass meter causes ESP problem) Hello, I drive an A3 1.8 T with 180 hp. Had power problems until I tested the plug to the LMM (air mass meter). That helped, the engine has full power again. However, when I pulled off the LMM plug and then started the engine, since then the ESP warning light and the ESP, ASR, EDS… don’t work anymore. Is this a strange coincidence or does it hang together? Even with the LMM plug-on, the ESP warning light and the ESP, ASR, EDS… Plug still burns the lamp. Do you have similar experiences or solutions for this? Thanks to you.
