Title: No volume on sound system
Post by: Graemehaw on 24 July 2019, 16:59
Hi all
I have just bought a 2014 golf gti. Loved it. However 1 week into ownership and im hit with a bill for 5.5k.

Basically the volume on the sound system would only go up halfway. Took to VW they updated the firmware, made it worse and now it has no sound at all.

Great. They have quoted 5.5k to fix

Surely there must be another way?!

Is this a common issue? If so is there a work a round??

Just sold my Renault Megane and that has had less electric electrical problems than this in my 4 years of ownership.
I was led to believe VW were better made.

Really dissapointed

£5.5k to fix?

Really? Have they at least explained exactly what needs fixing? I don't think a brand new head unit costs anywhere near £5.5k so I think an explanation is needed.

If not, try an indy. You may get more sense from them. Or at least better customer service.

Is the a main control module?

I've asked for a written quote and what it includes
Are there different parts to this unit?
Ie head unit and DVD drive in glove box
Is there an other parts to it?

I managed to get the sound back on after watching a you
Tube clip but sound control still only works up to half way
At least it's got some sound. The engineer could not
Even don that
The service girl did not have a clue
Just kept repeating herself that it would be
5.5k to fix

Name and shame the dealer. Sounds like they are trying to pull your pants down.

Sorry to hear of your sound problem.

This may sound obvious, but have you tried moderating the volume using the controls on the steering wheel?

Yeah I was going to ask if the problem was the volume knob on the unit.... so yes try the volume on the steering wheel...
Title: Re: No volume on sound system
Post by: Graemehaw on 24 July 2019, 21:28
Yeah the controls on the wheel are the same
I'm convinced it's a software bug
But updating the firmware did not work
Title: Re: No volume on sound system
Post by: Graemehaw on 24 July 2019, 21:34
I have the sound working again but again only up to half volume

Have you tried a reboot?

Hold down the power on button for ~5 seconds
Title: Re: No volume on sound system
Post by: Graemehaw on 25 July 2019, 09:02
Yeah sadly the reboot doesnt work

This sequence I found on you tube does seem to work
https://www.youtube.com/watch?v=r540d-pcw40

But I have to do it everytime I start the car thanks to VW

The issue was not loud sound before I took into those idiots, now no sound, untill I complete the above process everytime I start the car

Gonna do some more research into this, it seems a common issue. Im just really surprised there is no one here thats had the issue?
Is there a separate amp anywhere?

Have a look on honestjohn. He regularly recommends electronic specialists for this sort of thing. Ask him if need be, all free. £5.5k is criminal.

Try these people:

https://vw-retrofit.co.uk/

They fit OEM nav units to Golf's without nav. They have parts and technical capability.

I have seen people say that a Mib2 nav unit is only £650 supplied and fitted.... I expect they can fix your problem for a few hundred quid...

These guys have a great reputation and also offer all types of repair or upgrade for much less money.

This sounds like it shouldn't even cost that, to be honest. It's a software bug, isn't it?

I reckon VW were quoting for just ripping out and replacing the whole lot, speakers and all, including labour.
Title: Re: No volume on sound system
Post by: Watts on 25 July 2019, 12:55
Can't the unit be "un-updated"? Presumably at some point a bug has been introduced and you need to get it back to how it was like a return to as it was originally. I agree with sjw, this shouldn't be costing anything. I'd be concerned that replacing a part may not solve the problem.
Title: Re: No volume on sound system
Post by: fredgroves on 25 July 2019, 12:59
Possibly not. If the code update function has a check that says "if the proposed version is greater than the current version then update..."

Quite a lot of things won't let you downgrade in that way - you have to effectively wipe the memory and flash from new.

We have factory equipment that is just like that and its a b1tch.

Bugger. Modern stuff might be flash and high tech but when it goes wrong it's a big pile of sh!t :rolleyes: Roll on the MK8 with a new selection of software issues...

Post by: Graemehaw on 25 July 2019, 13:27
So spoken to VW again and the cost is £5,208.64 plus vat plus fitting plus coding.
The part they will replace is JUST the main unit.
This is the drive that sits in your glove box.

Nothing else, no new screen, speakers, JUST THAT

As already said its almost HALF the price of the car. An insurance company would write the car off. Totally ludicrous.
Title: Re: No volume on sound system
Post by: fredgroves on 25 July 2019, 13:36
Thats crazy. Those guys we linked above would give you new screen and box for about 600.... I am sure they can fix this for you!

I had a similar issue with my Mk7 2013 GTD. 6 weeks after the warranty had expired my media system just stopped functioning. The tech at my dealership did everything he could, but couldn’t get it working. VW themselves were incredibly unhelpful and I was quoted £3500 for a new head unit. Luckily for me, the dealership felt this was ridiculous and replaced it for me, I don’t know if they got anything back from VW, but they kept my custom. Whilst I’m no expert, I would have thought that the sale of goods act may assist. Is it reasonable to expect a £5000 media system to pack up after 5 years? I think not. Good luck with your endeavours.

If you've only had the car a week, can't you take it back to where you bought it from? Or was it a private sale?

Was thinking the same.
Title: Re: No volume on sound system
Post by: Graemehaw on 25 July 2019, 13:53
Private sale sadly.

The links people have posted have been brilliant, looks like its a common issue and can be fixed for around £400.
I can even find brand new on line from car electric places for circa £2k so where are VW getting 5+k from?!
Title: Re: No volume on sound system

VW main dealer pricing... you haven't had a VW before have you... its all ok until its out of warranty...
Title: Re: No volume on sound system
Post by: Guzzle on 25 July 2019, 14:03
If you're going down the replacement unit route, be aware that Discover Nav and Discover Nav Pro are two different units. Fine if you're not bothered, but don't buy a Nav thinking it's a Nav Pro!

Thanks yeah have checked that, mines a pro
Ive heard theres a later one that has carplay etc as well

There are actually three later Pro ones !

MIB2 adds car play/android auto and VW CarNet - same physical form as your existing one.
MIB2.5 adds the much bigger Mk7.5 buttonless touch screen
MIB2.6 adds permanently VW connected  CarNet with a GSM modem (built in VW SIM). Mk7.5 from about November 2018 onwards.

2.5/2.6 is kinda my name for them, I don't know what VW actually call them.

Have you tried disconnecting the battery and leaving it off for 10 minutes or so?

Might be worth a try before chucking a load of money at it?

Also I had a BMW and it started doing all kind of strange electrical glitches (including something with the stereo) and it needed a new battery-might be worth a shout on a car of this age?

A great reputation for being massively expensive. Still cheaper than VW mind.

Tell them to go and swivel. £5.5k is a ludicrous price. Not sure why they'd price themselves out like that, surely if other places are doing it for a few hundred quid, they should match that as it's better than nothing? What a strange practice.
Title: Re: No volume on sound system
Post by: Guzzle on 25 July 2019, 18:14
The places doing it for a few hundred are likely to be used/reconditioned units. Or dare I say via 'unofficial' supply channels. I doubt your local dealer will offer to provide used parts. These units also need to be installed by someone that knows what they're doing to overcome the component protection, it's not a job for a novice.

The theft protection setup is not that easy either. Units are paired to the original ECU and need recoding to pair to your car. Involves internet communication with VW HQ I believe.

I’d be inclined to go to a Indy with a vw licence for upgrading modules, and get him to check the update, or see if he could redo it, as I’m sure this was just a firmware glitch
