Hi another newbie

Hi - Got a MK7 Golf GTD - i think it was a Friday afternoon car had lots of problems with it.

Welcome Stubaxle 

What’s gone wrong with your GTD?

[Stubaxle]

Hi
Battery dead - replaced
Front wheel bearings
Wing mirror
Both rear brake calipers siezed

Now no sound from infotainment system
Tried restarts a thousand times, connected neg & pos battery leads [disconnected battery] to drain capacitors - no luck
took the main unit amp out in glove box to look at connections all seems ok
If i leave it overnight get in, i get sound,if i drive to supermarket for a bit of shopping, i get back in and no sound until day after when left in cold weather
then sometimes just out of the blue after say 4 days of no sound it will just come on randomly.

All auto sparkies want silly money just to switch on ignition.... then usual response is just replace everything.
the main display is fine - Sat nav , media, bluetooth, i can see phone calls coming in but no blooming sound on anything 
the park pilot sound works but i think this may be on a different system.
Pulled out a few fuses... all in tact.

its model MIB MAIN-UNIT 5GO 035 020B - HARMAN

me hopes its just a connector somewhere. but feel it will cost almost 4 figures to find out unless some infotainment ninja on this forum can suggest something to get me driving around with my favourite play list banging out again.

No sound = dark cloud

Thanks for asking.... hope you noW don't regret it

A few unpleasant bills there Stubaxle but wear and tear stuff depending on its use.
How old is the car? Mileage?

If I were you I’d post up a dedicated thread about the radio weirdness if you haven’t already in the mk7 section. I’m wondering if the component protection is activated following the battery change. I’m probably wrong but someone might have a better idea. It would drive me nuts too!

Hi Exonian
Yes racking up bills and not happy
i'll give it a try to see if the electrical ninjas can help.
do you know if its a common problem on MK7's?
I was going to see if VW customer services are willing to help

The rear callipers are probably from lack of use if the car has done quite a lot of cruising motorways and A roads. They can seize over time.
The battery is about right for the age of the car. It seems relatively common.
The front wheel bearings I’m not aware of being a common fault.

The radio unit is perplexing. Hopefully software related.

spot on Exonian
the infotainment came on yesterday ..... until i decided i needed some milk, got out, got milk, got in, got nothing from the speakers no sound again.
as the french say ....Sacre bleu.

Have you tried running a diagnostic check as that can sometimes throw up clues? Also worth checking for any software upgrade unless already covered. Sounds like a loose connection though.
