2003 Bora 24v V6 4Mo
Intermittent problem. Car acts like it has a weak battery and takes a few cranks until it has enough power to start.
Recurring codes are; 17925, 17457, 17935.
Car drives fine once started. Fuel pump is priming at door open. All fuses are good.
The clock and odo reset sometimes on startup as well.
Every now and then after a hard start it will not rev but after a restart will be fine.
Found this thread which is similar and got me on to this forum:
V6 4Motion poor / non start
17925 is coming back most often and points to relay 428 which I plan to replace.
Any advice before I do? Thanks
