    Hi guys.. here is my issue... I replaced the brake booster and then went to bleed the bakes using tecstream. I get to the brake bleed utility and start. It immediately comes up with the box saying brake bleed failed. I followed the instructions... ie brake on... car on without ready.... unplugged the fluid level sensor .... and still it doesnt work. Do i have to reset the memory and do a relearn too?? i got a replacement boster with all the same letters LC and same serial numbers.

    I've used Techstream (same laptop, same software) with two different dongles on my Gen 3, one of which could do the brake bleed procedure without incident, while the other one had lots of, um, incidents.

    Used brakes parts are not really a good idea....
    I hope you can get it working soon.

    Did you check with the dealer to see if it’s covered under warranty?
