Hey, I have an infotainment unit took from 2018 WV beetle. It is very likely compatible with your VW golf. If yours is fried and you are in Toronto, pickup from my home for $50 or a case of beer.

If your battery was dead, you need to question why? Driving around may be enough to recharge it but maybe not. A battery charger is almost always the simplest option to recharge it.

it might be possible that either your alternator is bad or your battery is no longer holding a charge. Do you have a multimeter that you can use to measure battery voltage? There are reports on the mk7 forums that the OEM battery only lasts 2-3 years. In your case you got 5 years out of it which is about the lifespan of a battery.

Check the VW Owners manual there should be a page or two that tells you what each fuse is and where its located. If not it should be online somewhere.
^What these guys said. These vehicles do have electronics sophisticated enough to shutdown certain items when it knows the battery is weak/not charging or if there is an alternator issue... In the case of an alternator issue you should also get the light on, in the dash. However shutdown or delay of these non-essential electronics should only be temporary until the battery gets up to charge--if you drive on the highway a short while they should reactivate unless the battery or alternator are bad. In these cases you should get a DTC setting though.batcave wrote: ↑ Some VW radios have fuses on the rear of the head unit. Yeah really. You may need to remove the radio to replace the fuse if this applies to you.
I should also mention that I had a power on problem with my radio and it wasn't a fuse. I disconnected the battery and reconnected it and it worked. I'm not sure why.
I have an Audi, not a VW, but very similar.

Yeah because these cars cook the batteries. Engine bay gets way too hot, esp. after shutdown, battery has no chance to last that long. The older cars with the VR6 (Mk5 .:R32, A3 & TT 3.2L, etc.) have the battery in the trunk which is a much better idea. I believe there might have been a TSB for early battery replacement but sounds like OP is out of warranty and I don't think that TSB actually extended the warranty for the battery either. Temp probably wasn't a problem for the non-GTI Golf in previous years but the 1.8T and 1.4T probably have an engine bay that's just as hot

I did turn off the infotainment system just before the jump start (it was still working just before), that's why I can't understand why it's not turning on.ES_Revenge wrote: ↑
One thing to always remember for the future. A tip for everyone not just the OP. Whenever you are jump starting either with your car to another dead car or vice versa--always, always, turn off all the non-essential electronics like the stereo and HVAC. This will prevent any surges from possibly "frying" such components which can and does occasionally happen. Hopefully you haven't done that in this case but just a word of warning. This goes for factory stuff as well as aftermarket.

Damn, well that's not good I'm guessing you don't know anyone with VCDS or OBDEleven? When the battery was replaced, how long was it left disconnected? Was it at least 10 mins?
