Help facing a major issue
Hey everyone, hoping someone can help. I have a 2012 VW Polo GTI 1.4 TSI that broke down and I’m stuck.
What happened: Was driving normally when the accelerator suddenly became unresponsive, battery warning light came on dashboard, then the car stalled and won’t restart.
Current symptoms:
• Cranks normally, fires for 1-2 seconds then dies
• Battery was completely dead (jumped it but still won’t stay running)
• No fault codes on OBD scanner
• Already replaced spark plugs
What’s been checked by mechanic:
• Fuel pressure ✅
• Compression ✅
• Spark plugs ✅
Mechanic has given up after 3 days with no solution
Strongly suspecting alternator failure and/or crankshaft position sensor but not confirmed.
Can some please suggest anything if any1 has faced same issue or any good mechanics in Melbourne
Car is currently in Melbourne VIC. Any help or recommendations greatly appreciated! 🙏
