I have noticed that since the garage has had a play with the aircon my main fain intermittently comes on full blast like its really hot even when the engine isn't that warm, I had a word with the guy who worked on it and he cant understand why as he never touched anything to do with the fan. Could be that all the gas has been taken out the aircon and this is causing problems? Also I got the part number for my compressor - 5KO 820 803 A, I see there are lots of other compressors with very similar part numbers like 1KO 820 803 A or 5KO 820 803 B would these also fit?

Good thread.. I just got my 2008 Octavia 1.9tdi back from the garage for an aircon re-gas, he checked for leaks which was all good, filled it up, found the compressor clutch was shot so took the gas out, he said its not that hard to change as can be done from underneath but the garage want £580+VAT which includes new compressor. So if I was to do it, is it as easy as he said? If I can take off the compressor could I just change the clutch or is it easier to replace the whole compressor? Cheers..

Further to my problems I have an update, this morning while giving my lad a lift to school the Bolero sparked into life! Yesterday in all that heat it was so frustrating, everything I tried and had silly in between volt readings with nothing working, I felt for sometime it was to do with the CANbus, after all it does control the on/off function of head unit, maybe leaving it overnight and taking it for a drive this morning reset it? Messing with the amplified aerial while connected defiantly messed it up as I watched it flicker and go blank while I was unscrewing the 22mm nut, so lesson there - make sure everything is off and unplugged before metal to metal contact! Thanks Langers2k for your replies, it was much appreciated

Thanks for all your help so far.. Moving on, I checked Fuse F8 radio and its just over 12+V so all good, checked block connector again, 8.6V?? Now the ignition switch made me think again so I swapped that back to the original that was temperamental, checked the block connector again 12+V - great, plugged Bolero back in - nothing, tried Stream unit again nothing, unplugged and check block connector again back to 8.6V - what is going on! As a last chance I put the new ignition switch back in but block connector read the same 8.6V.. All this from undoing the amplified antenna without unplugging it. I'm at a loss now so I have put it all back together and I'll have to drive without no radio until I decide what to do next - very frustrating but thanks for your replies so far.

I have now double checked all relevant fuses in engine bay fuse box, so F8 = 15a radio fuse, F12 = 5a Can databus, checked power at rear block connector as suggested and getting around 7v at both positive connections. Tried both my Bolero and Stream head unit with and without the aerial connected and still no joy, it feels like it’s a simple fix but I can’t put my finger on the problem! I’m thinking if the antenna base is shorted out/doesn’t work that may render the head unit to not respond, I did find when I connected the Bolero the first time it wouldn’t switch on with just the block connector connected, as soon as the antenna cable was plugged in it came to life. If the Can databus is shot is it a case of find one used and plug it in or would I have to get it programmed? Sorry for all the questions but it’s driving me mad!!

Thanks Langers, will give that a go now and report back..

Thanks for the reply, the thing is I tried the old Stream that I took out for the Bolero which I know works and that is completely dead too, this makes me think that there is something between the head unit and aerial that has blown/shorted. I do need to check the head unit is getting 12v, if that isn't the case and the fuse is okay what could be the problem - Can Bus?

Hey all hope you can help.. On my Skoda Octavia MKII the antenna/aerial is powered, after taking the antenna base off yesterday I seen the head unit shut down as I foolishly didn't unplug it while unscrewing the 22mm nut, I must have sent a short through the system, now, the 12v powered antenna cable in the back of the head unit has no power and the HU will not switch on. So does anybody know where the power for the amplified antenna resides as in fuse box, inline fuse somewhere, or if I shorted out the antenna base would that cut power to the cable? I know its not the radio fuse in the engine bay box, or the 10a in the back of the HU plus I tried another HU to check I didn't blow my Bolero Very frustrating so any advice very welcome

UPDATE and hopefully helpful to others...but I need more help! The issue I had with the Stream cutting on/off very quickly started to happen with the Bolero - WHAT! So back to the Google searching and Briskoda links popping up with some people having trouble with their Ignition Switch, this can cause all sorts of problems but one of them is like the issue I have, so I replaced the ignition switch today and YES it worked, I have to say it sounded better too, much more punchy solid sound, no idea why this would be the case but it defiantly is? NEW PROBLEM - I knew my ariel/antenna signal is weak due to water ingress so I took a look at that, maybe a bit confident from doing the ignition switch I started to undo the bolt under the antenna, with that the Bolero flickered and went off and will not turn back on AARRGGGGHHHH!! Stupid me didn't unplug the antenna first - have I shorted the system out? I have checked all the fuses in the engine bay and side access box, I took the Bolero out and checked the rear fuse, all okay, I even put the Stream back in and thats dead too, what could there be between the antenna power and head unit to cause this - Can Bus? I dont have VCDS but its tempting with all these problems I'm having.. Anyone have an idea whats going to kill the head unit by messing with the antenna while powered?

Okay thanks, I thought it was an antenna lead. DAB is what I'm really after either through BT or the AUX, with the Stream I just plugged my phone into the AUX cable and DAB from that, as I said the Bolero is not playing ball with the factory AUX and doesn't have the option in the menu? very confusing.. I suppose there is always aftermarket DAB tuners but using the Bolero is the preferred option, what would you do in this situation?

Looking at other threads on BT modules I take it I haven't got one fitted as when I press the Phone button it just mutes? Also is this white connection power or antenna, as I said the Bolero is a double whereas the Stream and my car has only one round connector?

Hi All, Hope I can get some advice on a newly installed Bolero in my Octavia 2008. So how I got here, current Stream was popping, shutting off and on, was making a weird cycling noise when keys were out so I bought a Bolero from eBay, installed, got a code from eBay and working. Problems - The bluetooth is selected on but phone doesn't find it so taking this is only available on later spec cars? The factory fit AUX that worked with the Stream now does not work - the AUX on/off selection button is not in the Media section unlike Youtube videos showing it on the Bolero When I turn ignition off it acts similarly to the Stream as in shutting on/off/glitchy so could I have a bigger problem with say the CanBus? Not so much a problem but when plugging in the wires I noticed the Bolero has 2 round white connections next to each other like a shotgun whereas the cable in my car has only one single round connection? Hope some of you help and how you got past the same problems if you had them. Cheers.

I know it sounds obvious but the part number is on the connector and has the VW/Audi stamp, doing various searches under that part number the antenna could be the twisted wire type or the bee sting type which gave me doubts, perhaps I'm over thinking it!

My antenna is shot as it has the dreaded water ingress, looking at the part number on the white connector 6Q0035575A this antenna comes up for VW, Seat, Skoda, they look the same, have the same connectors but are they they same as in electronics in the antenna base? Cheers..

Thanks for all your comments, just gone with a Bolero upgrade (£70 eBay) for now and will buy a code from eBay or is there anyone here that provides this service and is reccomended? The Android system is nice but as my car is 2008 I don't know how long I will be keeping the car so don't really want to spend £200+ plus. The Bolero does looks a big upgrade from the knackered Stream and If I decide to go Android in the future I'm sure I will get my money back on the Bolero with the code.
