When you want to move the battery to the boot (as located in the GTI), where do you have to enter the 35mm2 cable, somewhere around the ECU or where the heater tubes pass the bulkhead ? Erreesse

Had some issues recently that warranted a heap of cranking so i had to put the battery on charge in the garage. Charged it on the 'low' setting (3-ish amps i think), charger gave the green light, battery is sprightly and everything seemed great. Fast forward a couple of days and I was greeted with some intense rotten eggs through my heater blower in the morning... Checked the battery and it isn't venting anything visibly (i.e. any contents spilling out), still works great etc. The alternator voltage regulator is working fine as I checked this as part of my recent issues. I can only assume that this charger overcharged the battery a bit and this is Hydrogen Sulfide venting out the battery from that. The way I park on the drive means that the gas could pool in the battery tray a little (rather than flow down and out through the drain hole in the wing) and then be briefly sucked into the blower through the scuttle. H2S is smelly in low concentrations (before it gets so bad it stops you smelling it.....) so this would make sense. Either way I'm buying a new battery but I'm guessing this charger's over-charge circuit is duff right? I've barely had to use the thing and in my experience 12V chargers are normally pretty bombproof - not a whole lot of circuitry in those things.

ABS & Power Steering Warning Lights - Help Please
Adam199 posted a topic in Wheels, Tyres, Suspension and Brakes
Hi, I bought my first car, a VW Polo 9n (2009) in early 2020 - so very much a newbie to cars. I fitted a new radio in July of that year (incorrectly at first, which led to a flat battery from radio being left on, but later sorted it so it turned off when I switched off ignition). It may not be linked but, a month or two later I started experiencing problems with ABS warning light turning on and power steering failing. This was very intermittent and only seemed to happen when driving in traffic, with phone plugged in and radio on etc. Garage immediately said it was the alternator, but no warning light came on for alternator, also no error codes showing up when scanned, the voltage to battery and alternator was good. They said not much point changing alternator as it looks fine when tested. I left it for a while but same thing happened when driving in slow moving traffic (air con, phone and radio all on) and so I thought I should get alternator changed for peace of mind. It was changed and no problems with the car for the next 7 months or so. About a week ago the same problem has started again. Abs light on in traffic, power steering goes and warning lights on. When I pull over and restart the engine I lose the warning lights and regain power steering. Took it to a different garage this time (I've moved), they scanned it and said it was an ABS Pump fault (they checked voltage on battery and alternator and fuses e.t.c). I asked them to take a closer look as i suspected a more intermittent electrical fault and now they are getting a low reading from alternator (under 13.5 watts), when all electrics turned on (fine otherwise). I can't go back to old garage (too far away) for warranty on the alternator that was changed less than a year ago. First step I've been advised by various car mechanics is to change the alternator again as I may have just been unlucky with a dud, but if I do replace it and continue experiencing issues does anyone know where to look? Would love to know if anyone has experienced similar problems and can suggest some solutions.- 3 replies
