battery

I have an S3 8V facelift. When following satnav the MMI reboots after about 15 minutes of driving. The screen retracts into the dash and the unit completely powers off before coming back on (without previous destination routed, very annoying). The problem started after I took it for an MOT and...

Hi everyone, Background I have an AUDI A3 1.6 TDI 2010 (8PA), 126K mileage. Last year, it was overheating and so was driven without a thermostat for approx. 6 months until the cause was identified and fixed (it was the heater matrix which was replaced alongside the heater matrix connecting...

Hi Guys, I’m hoping someone can point me in the right direction, on 3 different occasions I’ve turned my key to turn the car over but before it can even reach the first ‘point’ of the key turn where it just turns on everything electrical like the radio the dash goes dead for a few seconds...

Hi All Looking for a bit of advice on replacement battery. I've got an A4 B8 Avant 1.8 TFSI (2010), had the car around 7 years, post-lockdown every now and then get warnings about low battery (getting more frequent), do lots of short journeys with the occasional long journey. Have charged a few...

Hi, I have a 2011 A3 1.6 TDI with Start-Stop. The car came the original Lead-Acid battery (the label is identical to that shown here P/N: 5K0 915 105 G) which now won't start the car. The Start-Stop functionality hasn't worked for a number of years (see below). Therefore I want to know: If I...

Hello everyone, first post here. So, yesterday I drove my car for about half an hour, and it worked perfectly until I turned it off. Today, I woke up and went to the car and found some of the dashboard lights kinda half turned on, the car doesn't respond to anything, like, the keys don't do...

Hey everyone, Does this mean i have a parasitic draw or not since im not familiar with multimeter readings.

Got AUDI A4 - 2 years old now. Car was telling me to replace battery - I did (twice)...same problem. So I used my spare FOB. Was fine for a while then same message appeared for 2nd key. Went into AUDI spares - they sold me 2 batteries and fitted them. I returned to the car and the message had...

Hey, Today it was -10 in the night and -1 in the mormjng, my car started normally in the morning, then i went to wash it started normally again and when i did the vacuuming the battery went flat… I listened to the radio and the battery is 1 year old… when we jumped the car everything was normal...

Anyone know what the alternator should be kicking out on an S3 8V? Mine wouldn't start yesterday, jumped it and drove a few miles and it just about started again, then drove about 10 miles and it wouldn't start again. Put a new battery in and obviously it now starts fine, for now... Put my...

Are there any dash cams that can record in park mode for a few days without a battery pack? A back up battery is pricey. A Blackvue power magic ultra can cost as much as £330 which is almost the equivalent of what a dash cam costs. I’ve read some posts about dash cams in parking mode shutting...

Car is my partners 2017 A3 1.0 SE bought May 2019 and 3 years old on 31/01/20 At the end of December, the battery appeared (to me) to be struggling to turn the engine over. Not really struggling, just not what you'd expect of a 1.0 engine with a 700CCA EFB battery. We're talking maybe 3 secs to...

Good afternoon all, Newbie here (please dont moan lol) Firstly, apologies if this has been posted here before. I have a 2009 Audi A3 2.0 tdi with the stupid cluster/ not starting issue.....Done a bit of research, hence why Im here. So, my symptoms were/are.... NO LIGHTS ON DASH but Radio on...

For some reason I decided to use my second key to move the car around on the drive earlier in the week and the car decided to inform me that the battery was flat in the key. I've had the car almost five years and always used the same key. (2014 A3 Sportback SLine) I'm thinking either Audi...

Hey guys, I’ve been having a bit of trouble with the electrics in my Audi lately. On a long journey, the electrics will suddenly cut out. The engine will keep running but the instrument cluster, power steering, heaters, radio, windows etc stop working. AA fitted in a new battery and the issue...

Hi guys, Wondering if there's anyone on here that knows about the fuses in the A3 etron 2018? I've got a Blackvue Dashcam and Ultra Power battery setup and its all up and running, charging whilst driving, and so always on 24/7 (Parking mode), and it will last for 2-4 days. I've currently got...

I recently saved a 2004 A3 2.0TDi sport from being scrapped by my non mechanically minded brother to hopefully fix up and the first problem I want to address is a constant battery drain of around 1.7 amps when everything is off. My meter covers DC amps. I took out each fuse one at a time to try...

After disconnecting the battery to replace the fuel pump months ago, the keyfob still works but after locking the car the alarm will go off beeping, then to flashing and then repeat this cycle several times. It is frustrating to the point we want to either leave the car unlocked or disconnect...

My battery which has been threatening to die for a while now, sadly gave up this morning. :( It currently has a Bosch S3 fitted, is this the standard OEM part? Looking online it appears the S4 would perhaps be a better replacement? (Car is an 3 door 2009 1.4 tfsi S-Line) Either Varta or...
