abs / hand brake warning light flashing?

cutting a very long story short, spent over 3 grand in 12 months fixing my car, and funds are very limited now. january my epc / traction control lights were on, took to garage, they cleaned throttle car ran fine until 2 weeks ago, lights back on, took to vw who did a lateral sensor and master reset, since then abs / handbrake lights are on, i was trying to sell the car, of course now noone wants it
any ideas .. been told it could be this, could be that, and after spending loads already i cant justify much more
