Is there any way to upgrade the ACC to PCC, as long as TSR can be upgraded by coding?

Yes, if you already have the front camera, for lane assist or TSR. Many retrofitters can do this for you remotely, if you can access a VAS5054 dongle. I wrote about my experience of having this done here: 

 

Thank you for updating me! My mistake, not enough searching.

Have you been pleased with it? Does it work well?

In a word, no. 

 

Because of covid, I only have experience of using it on my commute. On this 13 mile trip, mostly on a dual carriageway, it performs terribly. It consistently adjusts the speed downwards based on speed-signs on adjacent roads and sliproads, sometimes dangerously so. On one flyover, it reduces speed because it thinks I am approaching the junction which is on the road below me.

 

This is obviously a very limited experience of using p-ACC on one route, but based on that experience I couldn't recommend it. I have also seen others complain that the UK mapping data is not accurate or up to date enough to be able to use this feature well here. Your mileage may vary. 

 

I'd be really interested to hear other people's experience of using it though

Thanks for your speedy response. We should be able to hear from many more users, now that it is an option on new cars.

Wow, not very attractive behaviour of the car, especially on heavy traffic. Maybe on the highway, but it can be dangerous on high speed, though.
