Need help, Parkman 213 CLA C118

[Snkfear]

Hello everyone! I'm having some trouble trying to activate some features on my CLA C118 pre facelift manufactured in 2023.

When I try to connect to Parkman ECU I get an error saying "MaxLenght violation (PDU is too long), required bytes 448, available 920."


I've replaced some outdated smr-d files copying new ones from xentry install but when I try to replace the parkman one, DTS Monaco detects it as corrupted.

Can someone help me?
Thx in advance!

Hi, ur smr-d files to parkman its still to old because it doesn't show u variant of module, use a smr-d from Xentry.

Also u can try this one.

Thank you very much for the attachment, I'll give it a try later.

I already tried to change the smr-d file copying it from Xentry install, but when I placed it on the project DTS Monaco refused to open it saying that the parkman smr-d file was corrupted... but with the one you attached the project opens without issue!

Update:

With the SMR-D wojciech300 posted I've been able to connect to my parkman ECU and perform some coding.
At first I got an error saying that coding service was not supported in active session but after closing again DTS Monaco and unplug and replug the odb adapter it worked like a charm!

How did you manage to connect to PARKMAN213 and read codings using DTS Monaco? I have tried all the PARKMAN213.smr-d files I could find. Both old and new versions. And every time I connect to the device, when I try to read the coding, I get the message: "Error. Negative response received (26)". It seems I need to give extra access somewhere. I used DTS Monaco 8.16. Can you describe the entire sequence of actions starting from launching the DTS program?

Either it requires unlocking the firewall or if it is a W213 MOPF you will not be able to code PARKMAN without an enhanced certificate.

The car is GLB 250 4MATIC 2021. Where exactly do I need to unlock the firewall? In EZS167 I gave all access levels. After that I can do coding in CPC_NG, HVAC177, IC177, HU6, but I can't even read the coding from PARKMAN213.

I have uploaded some SMR-D files from the link below.
One of them is from 2023, which may solve your problem with old SMR-D files.
Hope it works.
