Thanks for the extra info. Following a bit of surfing I found the detailed Euro 5B and Euro 6 emissions online (where I saw where the NOx levels dropped in Euro 6); I contacted Skoda UK customer services (out of a sense of mischief) and asked them if they had the official figures for the emissions of the 1.6tdi engine of 2013 compared with 2015. You could have heard a pin drop! It was suggested that I should speak to a Skoda retailer as only they would be able to give me this information . Yeah, right! That was a sidestep worthy of a bullfighter. I suspect that they thought I was some reporter trying to stir up the system cheating story. Might go and torment a Skoda retailer later!

Thanks. So presumably engines manufactued from 2015 have lower NOx emisions than those from before. Interesting stuff.

Interesting point; a 2013 1.6TDi CR Elegance is listed as having 99g/km CO2 emisions, is £0 rated for road tax and yet is not ULEZ exempt. Only cars post 2015 are ULEZ exempt despite many of those I have seen having the same emissions figures. Anybody got any idea why?

I think you are right! Very relieved to have got everything working, and am very grateful to @langers2k for his assistance. Hopefully we can get together for him to cash in on the drinks tokens sometime.

All fitted and fixed. Everything is back to normal. Many thanks for all the assistance.

Sorted. We have 12v on pin 1. Main dealer replaced the fuse for slot 10 in slot 9 and in the dim light under the dash I couldn't see the slots, so pulled and checked the fuse far right thinking that it was fuse 10! Now awaiting the delivery of the replacement display.

Thinking about it, pin 1 is the orange lead that I had no continuity between the display unit connector and the 12 pin connector on the head unit which we were assuming was because that was CAN bus.

I checked all the pins and the only ones that had earth or voltage are those mentioned. Pin 1 certainly had nothing.

Your assumptions on what I have done and found are correct. Now I understand what the yellow ones are and why we can tick them as fine, thanks I have ground on socket 7 of the display connector (useful for them to have them numbers marked!). 2.5volts on socket 3 and 1.5volts on socket 9. So if that is what you expect we are looking good. I have sourced a display unit on ebay and will be buying it this evening. Hopefully all will be well when I fit it! I will keep you posted with the outcome. John

Hi Langers2k, Checked the feed to the sceen and came up with some interesting results. The red/white, blue/white, orange/brown and orange/grey all gave a full scale kick on the ohms meter so no continuity issues there. However there were an orange cable which gave nothing, and and orange/lilac which gave a small reading 3000 ohms rather than the 100,000 ohm full scale reading. I could not see any sign of the latter two cables on the diagrams you sent me linking to anything that made sense. Am I missing something? Also I am used to continuity tests being a yes/no result and not a small meter reading, which I do not understand. I have attached a picture showing the cables at the head unit end of the loom to demonstrate that the plain orange cable is really a plain orange cable! The fakra cable, as you suspected showed full connectivity. I am at a loss as to what I should do next. Cheers, John

So if I drive the car around the block those codes will auto reset? Got it into my head that the radio was fuse 10. You are quite right, radio is fuse 12 and is okay. I have just pulled fuse 10 and that tests out fine. When I was looking for the screen in the manual, I was looking for "Display Screen" and completely missed that it is "touchscreen". Damn! Off to try and test the rest of the feeds to the screen

Full auto scan attached. Will be continuity checking the display later today (won't be adding power! Fuse 10 is the radio according to the owners handbook, and I pulled that to stop the radio's quiet playing as the volume control on the display does not work. So that fuse is okay. I went looking for a Display screen fuse as soon as I realised that the screen wasn't working. Couldn't find one listed. Seems odd that there isn't a fuse to protect the screen against power surges (like numpties touching a socket bar against the positive terminal ). Thanks, John Log-FD63 BSX-TMBKG7NE6E0116084-128983km-80146mi-v2.txt

Yes would like to know how controller maps are created. I learn better when being shown rather than reading manuals! Yes I read the read me file and have saved the log file on my PC as well as my laptop [hard drives can fail, and will do so when you really need that file] Thanks to everyone who is helping!

Just after I posted the last update, I remembered that I had removed the radio fuse as the radio was playing softly enough that it could be heard around town, but not on motorways etc. which was driving me crazy! Replaced fuse and rescanned. Everything the same except for: Address 5F Information Electr. 6691 Data bus for Control/Display U10AD 00 [009] - No Communications Must admit that the VCDS is a great tool, it's just that it propduces SO MUCH information that working out what it all means is a bit daunting for a newbie!

Received the VCDS this morning, and ran auto-scan Following faults came up: Address 3 Brakes 16401Tire Pressure Warning. I know about this one it came up after the initial problem with the lights staying on and the blank display screen. Just need the display screen to reset tyre pressures! Address 17 Instruments 3 faults found 16777018 Function Restricted due to Interrupted Communications 16777020 Function Restricted due to Interrupted Communications 16777022 Function Restricted due to Interrupted Communications Does this mean that VCDS had interrupted communication or instruments did? Address 19 CAN Gateway 66052 Infotaiment CAN Bus Address 52 Door Elect, Pass. 589843 Window Regulator Front Passenger side. Not noticed anything wrong! not too worried about this as I suspect it doesn't have anything to do with the display being blank Address 5F Information Elecr. Cannot be reached Is this due to the failure of the display screen, and/or head (control?) unit? My question is this. Does anyone know if any of these fault codes confirms that the display screen is dead? Should I being doing more than just an Autoscan? I have been having a Google around but haven't found anything helpful yet. I have been told that fitting a second hand screen is straightforward and effectively plug and play, so should I go ahead with a second hand screen and see if I get some form of life, or is that just too simple?
