Short circuits all over the place.. HELP!

[Shubz8p]

Hi all, this is my first post here. I picked up my first audi (8p 1.9tdi e) about a month ago and fell in love witb the car very quickly.. Until a week and a half ago.

My battery was going flat every morning - And I mean *flat* like unlock the car with the doorlock kind of flat. I’ve been jumpstarting it every morning and the hazards would come on as soon as the battery got a lick of charge, and the hazards wont go off until I pressed the unlock button on the fob, which tells me that something is setting the car’s alarm system off? But the car doesn’t make any noise. The confirmation beep doesn’t work either, and I’m pretty sure they both use the same unit to play sound.

a week ago, I was on the motorway and suddenly my glow plugs light started flashing (It’s kind of relevant I promise) and the car went limp too.

On the dial switch for the headlight settings, the led that lights up the icon for each setting is very very dim.

Yesterday I called over an autoelectrician, who ran a scan on my car and found short circuits all over the place (scan log attached).

The glow plugs, the alarm system, the dial switch, etc

The man concluded that my priority is the glow plugs and the alarm siren need replacing.

This morning, when I jumped my car (I know I should be disconnecting the battery at night at this point) my headlights came on as soon as I jumped it! I checked inside and the dial was set to off.

Now, I’m planning on replacing the glow plugs anyway, but as for everything else - Sometimes these kinds of problems are caused by one thing rather than it being everything individually failing, and I’m ready to accept either outcome. But just before I go all in, I wanted to ask if anyone has any ideas?

Also, I am aware that the turbo over boost error in the log is probably why the car went limp that one time but I just think it’s a bit convenient that the glow plugs are shorting too.

Before you do anything or buy anything get the battery professionally tested, because a dying battery can cause all these problems. If the battery is more than five years old don't bother getting it tested, just buy a new one and get it coded to the car.

I feel like an idiot for not having mentioned this already, but I have changed the battery already since the problems arose.

That's a good start. Was it coded to the car?

No, I didn’t know youre supposed to do that

I'd bet that's the reason.

Well, the issues started occurring before I changed the battery. I changed it because I thought the battery was the culprit. The battery going flat only started happening about a week and a half ago, and the battery was changed just under a week ago.

Hmm, I think I’ll have to get my hands on a ross-tech. I’m going to get the battery coded in regardless now that I know it something that should be done.

However, I’m still doubtful as to whether this is the source of my problems. I’m deathly scared that there’s a messed up wire somewhere that will take forever to diagnose.
