hello I have had the vcds cable for quite a few years and used it successfully to fix many vehicles and make lots of adaption,, great piece of kit, I am a real VW fan and run a V6 Amarok as a family car.

One of my customers has bought a 2018 diesel VW Transporter, not sure which model it is, he bought the van and then found out it had a speed limiter set to 70.

I thought i could fix it with vcds, I have recently serviced the van and today finally got chance to do an auto scan and have a look around, please see attached.

I completed the autoscan, saved it then proceeded to go into the engine module, clicked security access, it highlighted 27971, i filled in the field and then it said :

controller refused to send a seed, Error 7F service not supported in active session,

I tried for a while and it would not accept the code. Please see the autoscan, I would also like to find the power output if that is possible from the autoscan engine code details

Thanks for reading, any help would be appreciated.

I'm afraid your VCDS cable can't modify this engine controller.
Have a look --> https://forums.ross-tech.com/index.php?threads/22540/post-196728

Anyways, VW has an updated ECU software for this engine, so perhaps the most beneficial way to proceed would be to have ECU reprogrammed with the new software. Reprogramming should clear also the speed limiter.

CXGB engine is specified as 75 kW (102 PS) at 3000-3750 rpm, max. torque 250 Nm at 1500-2750 rpm, comes with 5-speed manual transmission.

Many thanks for the reply, shame about the fix, he will be gutted, I think it has already been remapped hence he has missed his chance of the software update from VW.
Thanks for the engine power information and the feedback, thought I was going mad?

Is that why the module wouldn't accept the security access code?

Unfortunately your VCDS cable is not capable of coding/adapting this ECU any more. The protocol in the ECU is beyond capabilities of older VCDS. Also module 13 is beyond it's capability - see the faults.

You would need current HEX-V2 or HEX-NET interface to access T6 EU6-engines (ECUs made by Delphi) - as verified in the linked thread.

I don't think that's this issue here; in other words I don't think an interface upgrade will help with removing the speed limiter.

Check the ECU for the following Adaptation channel:
IDE02248 -- Individually adjustable top speed limit
and see what it is set to.

If it won't take 27971, check what you have in this measuring value:
IDE00323 -- Security Access: Number of invalid keys
