After recently getting my system (kenwood double din dvd, sat nav, etc.) fitted and then re-fitted (see earlier thread), I was less than thrilled yesterday when I picked my Octavia up from Vindis Skoda in Cambridge to find that in the four days it had been with them, someone had totally messed up the settings on my head unit.

Worse still, the front right channel is wrecked, I suspect the amp for that channel in the head unit has been blown. Just a tiny crackly output through the tweater, accompanied by clicking sounds.

I'm absolutely livid. Went in there before work this morning absolutely fuming. Waiting for a call back from them now. The car was in for a couple of warranty fixes, recall work and a new wheel bearing. They had no business even turning the stereo on.

Any advice or similar experiences?

That is totally unacceptable, throw the book at them!

I always take my face-off with me whenever the car gets any work done so that people can't fiddle. If you can't as it's double din just take a fuse out.

Maybe they had the battery disconnected.

Another possibility, you have not used the VAG wiring adaptor. When they plugged their diagnostic tool in they could have send 12V up the cable thats normally used to communicate with the OEM HU. The wiring adaptor bypasses this cable.

It's not that it's gone back to factory defaults. That did cross my mind, but it's definately not. On the damage front, I see what you're saying about the diag tool, but I'm farily certain that a proper VAG wiring adapter was used.

And anyway , the problem with the K-line was that it could send 12v to the diagnostics equipment and not the other way round.

This sounds like a blown speaker or channel on the amp

Phoned Skoda customer services so they have a log of the incident. Agreed to call them back once I've heard back from Vindis.

Definately sounds like the head unit that's blown, sounds identical to when my old head unit in my Mk2 Golf went.

it sounds daft but it is not a dodgy connection on the speaker?

I have seen before a problem like that and disconnecting cleaning the connection has soughted it.

it is probibly worth a check just in case

Seems unlikely as the connections haven't been distrubed (at the speaker end at least) in the course of this work at Vindis. I saw the wiring in the door when it was being done and it looked fine. Just seems a bit of a conincidence that various head unit settings have been messed with too.

Looks like one of their people just played a little bit too much with it.

The clicking I mentioned is like a clipping sound from the head unit really.

Out of curiosity... why are you using Vindis when you are from Derbyshire :confused:

I did use Vindis in the past, but everytime it went in for work it came back worse, so I wrote a letter of complaint and haven't used them since. I still haven't claimed my free valet!

And they tried to charge me

I've fixed the location in my profile . I live in Bishops Stortford and work in Cambrdige.

I've had a catalogue of bad experiences at this dealer, see here:

Vindis have now fixed my stereo. A cable had been disturbed during the work they were doing. This wasn't really their fault, it was the fault of the nobheads at Technicar for routing the wiring so badly (one wire even goes right over the passenger airbag unit probably rendering it useless ).

The only quibble I have with Vindis now is that my car should have been given back to me as clean or cleaner than when it went in. The inside of the windscreen and A pillars were filthy. They said their usual thing that they'd valet it next time it's in...

One thing I would like to mention about Vindis is their master technician, Danny. This is the guy that did the work on my car and identified and fixed loads of obscure rattles. He also fixed the stereo and stripped the dash and door just so I could see the dodgy wiring done by Technicar and take photos of it. Excellent bloke!
