Obscure error codes but DSC, ABS and Brake warning lights on dash. Would come on after a short drive, go out and then come back on. Called ECS and explained the problem and advised what I would need to do. Removed the entire ECU and Pump/Valve body, shipped to ECS via their online shipping process which makes everything easy. The online system reports progress, takes payment and repaired device returned 10 days after sending. Fantastic service.
