Next up was the battery, what a **** that was to remove, what a ****** stupid design for the retaining plate. Anyway after a lot of swearing and grunting out it was.
Forgot to take a picture of the area once the plastic support tray has been removed but it was in a similar state, anyway it wasn't too bad, nothing that would block the drain hole. Anyway I blasted it all down and made sure the hole was unblocked, the other side was totally clear but flushed it still, forgot to get any after pictures but needless to say it was nice and clean
.
So onto the issue I had, on the s3 the negative terminal is on the right not the left, me been in my own world removed the positive first, still never thought anything of this, was only when I refitted the battery and saw the positive terminal spark I realised the **** up, straight away I realised what I did and **** myself, put everything back together and wen to fire the car up and that's when the issues started, the traction control light was on, out came vagcom but it wouldn't clear the error, ****, after reading a few post I was none he wiser, so took the car for a spin, at first nothing really worked, the parking sensor were going crazy, the brake pedal wasn't working and the traction light was still in, ****** mint I thought, anyway after 200 yards everything went fine again.
Doing some more research on the web this seems a common fault/issue with the 8e, hear cats and their ****** electrics eh.
