**Need help reading VagCom diags**

**DopeAudi13** · 11-24-2018 07:20 AM

Been having a few issue with the car lately and I bought a Ross Tech V2 cable and ran the diags. But I am having trouble reading the results. Will someone be able to help me clear some things so I can start fixing them. Thanks in advance. I am having issues with the battery and alternator that I keep needing to jump my car. I also had an issue with the fans kicking on while the car was off (it was water in the ECM box). I already dried out the box and replaced the relays that were damaged by the water. But i think the car now is having trouble charging up the battery from it being drained by the fans kicking on before. I am also having issues with the ESP light on and before I had the EPC. Any help will be great.

Get the battery / charging issue fixed, that’s the first thing you should do.

Once that fixed, clear the fault codes and I reckon 99% of them will not comeback.

These cars start to throw codes when there is a battery issue.

The common reason for an alternator not charging is because of a shot alternator or battery. test the voltage by connecting a multimeter to the battery while the engine is not running. The voltage should be between 12 - 13 volts.

Have you checked your fuses ?

I have checked fuses and everything looks good on that end. I believe i may have a bad cell in the battery. the Alternator is charging fine while its running. I am going to keep an eye on it. the one that Im trying to figure out now is the ESP unit one.

ESP could be related to bad battery.
Go to some shop and let them test the battery for you

I keep having battery issues only when it sits for a while. If I use the car everyday the car runs and everything seems fine. I think the battery has a bad cell. But the ESP light has been on since way before the battery issues came around.
