Need Help ECU problem

[Hilal]

Get your battery tested. I had this same problem happen to me when I first bought my car, battery was dead, nothing would work but the engine still started. After I replaced the battery, got all the codes cleared, and it was all good.

Regarding your engine codes, thats something else.

You put a smaller battery in... And you've got a big stereo.... And you're having electrical faults...

2+2=4.

More electricity required. Thats why they have such big batteries standard.

Once the car is running it's the alternator that supplies power. Big stereo setups often have bigger alt's

I am running 2 amps one for sub and another for front speakers, car seems to start better with new battery.
It is not that small it is 450CCA which should be pretty good, I think standard is 500CCA or 550

Stereo works and lights on etc when car is turned off, so i didnt think the battery was lacking power

[Stuwey]

Yeah, but how many volts do you have???

You'll need at LEAST 14.4 to keep these little tech-boxes running. Faulty battery or faulty connections are where i'd be looking.

You have an electrical problem, which occured after you changed your battery system.


Return it to standard and go from there...

Battery has been in for 2 months, I had a electrical problem after 2 months of putting the Battery in so I didn't really think that there was 2+2=4 lol.

I know of someone who is running a real small battery and noproblems. I will try a different battery on the weekend

[minifreak]

Battery is in garage for you..ill charge it tonight and hopefully this fixes the problem..fingers crossed

I saw VWindahouse is running a Deka Power Sports ETX14 AGM, which is about half the size and power of my one, maybe a loose connection somewhere as I had to extend the wires

Would anyone know, or know where to find the battery specs of the polo

What CCA, AMPS, etc

[Jmac]

I fitted that set up to his vwindahouses car amongst many other things and it has never missed a beat, im pretty sure this is all going off track here, send the log mate

Yay thanks to Jmac who told me to check fuse number 7, now I have power steering and traction control, so I am half way there, it must have blown when i disconnected the battery to try and reset the computer.

I wish there was someone here like Jmac in Melbourne, there is no one really that i trust, most are just out to get $$, the real Watercooled community helps out.

If Jmac was in Melbourne, I would Gladly bring my car to him

Na-ah... we're keeping Jmac up here thankyou very much

[vwthunder]

People are quick to point the finger because I have done more than them to their polo's
It took me about 1 month to get the battery in there, and i did a lot of research on what battery to use, not wanting a under powered one

[Jmac]

Knew your Batt would be good bud, now have you checked those other things i mentioned??
Or are you like me and having a beer
