Assuming you did need coding, there are plenty of member with VCDS that are happy to do coding if required, it'll just depend where in England you are to who is local Anyway, I assume you're still trying to use the TEB7AS mentioned in your other thread? Not sure what the other module you've tried is? In which case, it seems others have had it working on a MK2 Octavia: - https://www.briskoda.net/forums/topic/209000-tow-bar-bypass-relay-wiring/?do=findComment&comment=2470657 - https://www.briskoda.net/forums/topic/179204-mkii-fog-light/?do=findComment&comment=2155362 I'd wire it up as: - Yellow, left indicator - Green, right indicator - Red, brake light (either side) - Blue, fog light (drivers side as stock cars only have one side enabled) - Grey, reverse light (either side) - Black, securely taped up - Brown, securely taped up - White, a good clean earth point! You've not mentioned if you're using a single 7 pin (12N), dual 7 pin (12N+12S) or a 13 pin socket. Therefore, I'd suggest you use the screw terminals on the TEB7AS to check which are getting power. Colours based from this PDF: http://www.towbarsdirect.co.uk/images/M7-WK7.pdf

I'd contact the bypass kit manufactures and see what they suggest? Otherwise maybe ask a local towbar installer if they have any experience with the Octavia and what kit they would recommend. Personally, this is one of the reasons I prefer dedicated kits over bypass style on modern cars

A wheel speed sensor would... There aren't pressure sensors, instead TPMS is done by comparing the rotation of each wheel via the wheel speed sensors. It could also be a corroded reluctor ring that the sensor reads. Ideally, the fault codes need checking with something VAG specific like VCDS.

We don't tend to use model years in the UK to describe vehicle ages. In this case, I expect they have a 70 plate which is likely a MY21 with an MIB3 headunit.

I think it's actually developer mode rather than diagnostic mode? I don't recall needing to enable it when I did my firmware update...

You should have a look around MQB-FPA, the section you're most interested in is profile position it returns to after restart. The only tweak I've made to my dataset is that the 'vRS mode' button only lights up in 'sport' rather than in every mode apart from 'normal'. Be warned, there are very real risks involved when modifying datasets so make sure you fully understand what you're doing...

In which case, reinstall the latest 20.12 version and contact ross-tech for support (https://forums.ross-tech.com/index.php). Assuming it's a genuine interface, I'm sure they'll help you to get it up and running Feel free to post a picture of it as that may also help clear this up.

You might want to start by posting an autoscan, the coding will depend what modules are fitted

No it doesn't, it used two rear radar units behind the rear bumper Still, I agree that given the OP doesn't have lane assist, no recalibration should be needed after windscreen replacement.

The first one isn't valid for MQB vehicles as there is no 'channel 34' :( The second one isn't possible by VCDS but looks to be possible by dataset modification

Plenty of people are happy with the stock and canton systems. Or at least happy enough they don't want to spend money changing it. As the connection between the headunit and amp is optical, the cheapest changes are likely to be replacing the speakers and adding sound deadening to the doors. Might be worth talking to an audio shop to see if they have recommendations? This might help:

Best bet is to contact a few VAG retrofit specialists to see if any can tweak the module if you post it to them. Lockdown restrictions means most are probably too far away to travel to. https://www.vw-retrofit.co.uk/ seem to be closeish but I've never dealt with them.

There are numerous versions which all look pretty similar depending on DSG/manual, backlight colour and if the wheel is heated. The part number will depend on which variant it is

Our Octavia's have the same headunit but mine is running slightly newer software. If you can share the files and directory structure, I can chuck them on a spare SD and see if they work for me

Certainly possible but not with VCDS. You'll need to tweak the lighting configuration directly in the BCM EEPROM using VCP or ODIS-e

ODIS or VCP can flash software and datasets, the harder part is finding the dataset... Where are you based? There are a few VCP owners on the forum so if you find one close, they should be able to check which datasets they have access to. Otherwise, there are a few companies that have access to ODIS who may be able to help. Including some that can do remote help if you have the right hardware

As far as I know, you need ODIS with a valid certificate and an online subscription to access the VAG servers. You can re-activate any SWaP/FeC codes that are linked to the VIN. Some are available to purchase later such as Smartlink or drive modes (at least for VW). I have no idea if TSR is just a dataset or SWaP/FeC issue on later cars, nor if there is any easy path to enabling it.

Welcome! At a guess, that part number is for cars a MK60 pump (with ESP) but your car has a MK70 pump (without ESP). It might help if you can confirm the part numbers of your existing ABS pump/unit

I expect it's become a FeC/SWaP function to stop people activating it for free It's normal that speed signs on the instrument cluster to need an appropriate camera and TSR enabled. Without the camera/TSR, it'll just show on the radio screen.

I'd earth it to a suitable point on the chassis. That's how the originals would have been wired in. As for the light switch, I believe it's pin 5 on the light switch to connector A, pin 21 on the BCM

Those wires aren't stock. You might need to take some trim off to find out what's been done. Looks like it's been cut off whatever it was...

Given it's only a couple of wires, I'd suggest you make your own loom The DRL connector is probably 1J0 973 722. If I recall, the fog is H8 so there are plenty of connectors online. edit: I think the original fog connector is 3D0 941 165 A edit2: Replacing the front loom could be quite a challenge and there are a few variants depending on your car's equipment... https://skoda.7zap.com/en/cz/octavia/oct/2010-663/9/971-971084/

A dealer can do it or you can do it from home assuming you can download the software update. Might be worth taking pictures from the 'system information' screen of your headunit and either dropping @pab567 a PM or add them to this thread: There will be a fault code stored due to the update but it's trivial to clear with VCDS or similar and completely normal. It won't show on the headunit or effect functionality

I'd suggest skipping eBay and grabbing some branded versions from a reputable supplier (local supermarket?) instead. Only because others have had issues with this style of battery from eBay and unlike an electric scale, your fob battery suddenly failing can be quite annoying

Why do you think it might be EGR related? - P0165 is fuel pressure - P0121 is throttle position Few links that might help: - http://wiki.ross-tech.com/wiki/index.php/P1065 - http://wiki.ross-tech.com/wiki/index.php/16505 Might be worth trying VCDS to see if it'll give you any extra info
