Stop start not working after being at dealership

What is brake under pressure too low mean?

My guess - it's just poor German-English translation: unterdruck = vacuum (as the brakes are operated by engine generated vacuum)

German VCDS:

Anzahl verhinderter Stoppvorgänge (Statistik)-Bremsunterdruck

Also what are you using to read that specific info.

The snippets were generated by VCDS - so called blockmap files which is a snapshot of all and every data parameter available from engine (or any controller).

---

VCDS > Applications > Controller Channel Map >

[ Single controller address - 01 ]​

[ Login or security access code - Leave empty ]​

[ Function - Measuring values ]​

[ Output - CSV file ]​

Go

The result file blockmap-01-... will be in folder C:\Ross-Tech\VCDS\Logs\....

Note: only VCDS HEX-V2 and VCDS HEX-NET cables have the capability to create blockmap files.

I have VCDS but it’s an older version and I don’t know if it can read a 2022 vehicle or not.

Surely there will be limitations - as noted above it probably won't create the blockmap file.

Instead it probably still can show all of the parameters - by searching and ticking them individually - max 12 at a time (of 1500 of total) - via
VCDS > Select > Engine > Adv. Meas. Values

The brake under pressure has me intrigued because since they replaced the brake fluid the brake pedal doesn’t feel hard when you come to a stop like it did, in fact you can sometimes push it all the way to the floor. Quite concerning really. Not sure what this means apart from it’s not right.


REALLY stupid question, how do I tell what version of cable I have?

I presume you've ceased to drive the vehicle if there are question marks over a critical safety system? The anchor pedal going to the floor is not good at all. Get it recovered and sorted. Phone Motability RAC, they guarantee to be out within half and hour.

It's printed on the sticker on cable's connector, also seen in VCDS Auto-Scan header. Well, only the newer cables are identified in the header - older ones do not identify themselves.

Good points, well made.
I would also add to get van recovered to the alternate dealer mentioned earlier in thread?

Yes parked up currently and not being used I value not only my safety but that of everyone else on the roads and pavements etc.. RAC are not 90 minutes if you are at home, in our experience recently it can be up to 48 hours.

RAC run a different scheme for motability to the commercial one for Joe Public. They have special patrols dedicated to just motabikity customers. They will come very speedily for a motability call - they're contractually obliged to.

You are crrrect about the different contract. We have a dedicated number to call and you get answered usually within 2 rings. The time is am quoting you are the worst case when at home, normally it is around 6 hours. I have been keeping a log just out of curiosity to see how slow they are.
