Galaxy ecu shutdown after alternator failed!

Recommended Posts

Hi, not sure if anyone has the answer to my problem as i have looked at many posts and cant find one that matches my problem!

i have a 2006 mk3 Galaxy 1.8 tdci , 6 spd 130k that recently had a failed alternator. i drove the car home just on the battery, as i was getting closer to home i noticed that most of the electrics were shutting down! i.e trip, speedo, parking sensors , seat belt warning sound, etc,.

After i replaced the alternator the car started fine ( with charged battery) only ti find that red warning light on, abs light on, no trip, no speedometer, no parkind sensors, etc,.

Has anyone had same problem that they resolved?

Thanks for reading my post,

What happened with the alternator?
When the Voltage Rectifier that seats on the alternator, starts to broke, he could fry delicate electronics devices, such as ecu.

Hi, the Alternator just packed in! Had red battery light of for couple of minutes after starting then it came on. Then after 2 days it would not start so jump start and drove home with everything electrical working as normal then slowly shutting down! by the time i got home very little was working, i just assumed the ecu was conserving power for essentials?
