No need to use VCDS after disconnecting the battery, just drive the car for a few hundred yards.

Any independent with an online connection to the VAG/Skoda servers can remove CP.

AFter 156,364 miles I'd suspect the DPF could be clogged.

These cars have a variable charge system designed to keep the battery no more than 80% charged, so the charge rate and the charge voltage varying is normal, whether that explains how much your idle speed varies I'm not sure.

It already is Superb Mk IV

Ever used the non-smooth version of Hammerite paint? That's hammer finish.

iOS17.6 is still developer beta, public beta won't be for a few days. I also see the black maps with Google Maps, so it's not just an Apple Maps bug.

Are the glow plugs in good condition, they're 9 years old now, and it sounds like they've never been as good as they maybe should be?

The data plate shows the engine type as CUNA, which AFAIK is the 2.0TDI 184?

Fuel starvation?

So max trailer weight is 3512-1912kg = 1600kg, which is slightly over the often mentioned 80% of vehicle weight guideline which would be 1529kg.

Check the vehicle data plate on your car for GTW. I *think* the 0kg GTW problem only applies to the Octavia 4.

Most likely you need to swap the ignition and non-ignition wires to the radio, usually these are red and yellow.

I agree, I had a non-res Milltek on a previous car and the drone was so bad I had to add the resonator after a couple of months.

Over several years I've asked Tracker to provide any data that proves the recovery rate with a Tracker is better (to justify the cost and risk of fitting one - I had one fitted to an Audi S3 but the install was botched leading to water coming into the drivers footwell), they have always failed to do so - simply re-quoting their marketing waffle.

That's just a scan, not a log of the changes you have made. Looking at that the problem is Trouble Code C110B54 - Adaptive cruise control sensor No basic setting. Somehow you've deleted the basic settings of the front radar. I think that means it needs recalibrating?

Does OBD11 save the changes you make (like VCDS does) into log files?

In the absence of any replies here I've gone with a personal recommendation of an independent in Bradford-on-Avon, VW Audi Cars and having used them twice now am happy to recommend them. https://boavwaudicars.co.uk/

@VWD I was pointing out that tuning a VCR to find TV stations isn't an option, as you now say yourself, as VCRs don't have digital tuners so using the VCR to select channel isn't going to work - you would need to select channel using the additional Freeview box.

Are there any VCRs that can decode digital Freeview transmissions not just old-style analogue (now turned off) transmissions?

Same thing at the Exeter park and rides.

I had that on a car over 40 years ago, the problem was that no coolant was reaching the temp sensors because of no water flow - if there's no flow then it really makes little difference where the temp sensor is!

Sounds like the linkage between the exterior handle and the actual lock has become disconnected.

I copy the old files onto a NAS drive, then quick format as it's quicker than deleting the old files.
