Car had been operating normally all service performed and no notification from dealership. On 10/26/2010 was driving at posted speed limit on alhambra blvd in pleasant hill/martinez CA. Was coming down slight hill and touched accelerator to climb slight grad when the engine just stalled and shut down. There was no warning. Car could not be restarted. There was a small noise from the engine compartment and a shutter as the mechanical power steering failed when the engine stalled. The car was put on a flat bed by martinez pd and taken to a local shop where nothing was done except call the dealership. The dealership, dorito bro in walnut creek CA, required the car be flat bedded to them. The car was taken to the dealer ship on 10/27/2010 the dealership then informed me that the battery was shot and they could not even trouble shoot the problem with out a replacement battery. There had been no battery failure prior to this incident. The battery was replaced and the dealership could not tell what was wrong with the car. On 10/28/2010 they believed it was the fuel pump. The pump was replaced on 11/1/2010 and the car could still not be started. The dealership as of 11/2/2010 has opened up another tech ticket to try to resolve the problem. 11/3/2010 was informed by dealership that the fuel pump needed new bolts because the old bolts can not be reused due to the sensitive nature of the tdi motor. I asked if the fuel pump failed and contaminated the engine dealership said no.
