As I told before, maybe not in the exact terms, but it is the architecture that varies. From what I heard recently, the lane change indicators could be customised by MASS using their SDT. Basically, the BCM and ECM arent the same. The car will have a number of such modules, interconnected through the CAN-Bus. Since I am not aware of the detailed aspects, this is what I can think of. Considering the case of a swift or its family, including ertiga, BCM controls wipers, indicators, rear defogger, central locking, interior lights and a few other components. Hence these features may be customised if there is anything possible. Perhaps the timeout for the lights could be changed since its based on a timer run by the BCM. Suppose you upgrade the instrument cluster of a Swift LDi to the one on the VDi, the harness itself is different since it doesnt need to many signals and data.

Features like headlight, fog light, mirrors, windows etc have distinct circuits that branch out at the junction box, after their respective fuses. The BCM of a top end swift will be different compared to the base version since there are some features missing. So is the wiring harness. Hence straight forward mods are not possible and easy like using the VCDS.

In case of a VAG car what I think is just everything is mediated by the BCM. Moreover, the smaller cars or lower variants will have the same backbone and wiring harness in most of the cases. Hence, you could enable some important features either only by coding or by addition of a plug and play module + adding that patch.

Could you explain a bit more about this. That is:

1) Difference between OBD and VCDS.
2) Does is have a separate interface like OBD or do you have to connect it to your laptop ?.
3) How do you connect it (the cable) to your car and where ?

OBD is to get real time readings from the car. For example, boost pressure, Rail temperature. OBD is also for Fault codes specific to Manufacturer+General fault codes.

VCDS is OBD+, it has all the functions of OBD and Additionally gives you options to configure the control modules. For example, it could be

1. Super high tech control to configure your ESP, Torque compensation, Brake force distribution, Angle and intensity of your Projectors, Internal Surveillance sensitivity, OR

2. Simple configurations like - enable sound unlocking, Enable comfort blinking of wipers (lane change)

VAGCOM connects to the OBD connector, over the years, the connectors have evolved

Laptop-(USB/Serial/BT/Wifi )- compatible VCDC Cable - OBD port.

Aah! this explains it perfectly :D

All excited at the prospect of unlocking additional "goodies" in my Yeti, I took her across to the Bosch Service Centre to get her "scanned". The owner said that he had the requisite software and cables, but was not very familiar with how to operate the software (My bad, I did'nt care to check which software he was working with). He was fairly confident that any features for which sensors/ wires were present could be adjusted/enabled.

I prepared a long list - thanks to various forums, from Briskoda to our very own Team-Bhp - of tweaks that I wanted to carry out and landed up at the workshop to implement them. The software in question was not "VCDS" but something called "bosch ESi 2.0" I guess it was an OBD system which allowed me to see various values and also tweak a few basic functions (like lane change indicator count) but did not have the more detailed functionality of the VCDS. I played around for a good half an hour, delving into every menu in the system (assuming that the functionality would be present but differently organized) but with limited luck :) - walked away doubting my "programming skills"

Now that I have read this it makes perfect sense - and I'm on the lookout for someone who has a proper VCDS setup in or near Gurgaon/South Delhi.

Can you share the link to this cable? I want to get my hands on to this also.

couldn't get exact url

but found an alternative

The amount of customisations VCDS offers is massive! Right from enabling the honk-honk during locking/unlocking the car using the keyfob, auto door locks when the speed crosses 15 kmph, auto unlocking while removing the key, enabling cluster staging (not possible on the stock clusters of the Polo, Fabia, Rapid and Vento), XDS settings, brake assist settings, number of lane change indicators, activating emergency brake flashers and so forth.

@Gannu , By cluster staging if you mean needle sweep - I will like to inform you it is possible in the stock cluster.

I have two weeks old vento and the needle sweeps on ignition.

Which cluster have you have installed on your Vento?

Ownership thread yet?

Its the stock cluster.

Ownership thread in the making. will post soon.

Could you PM me your Vcds Log file? Would like to compare modules

so cool. was the needle sweep on ignition "ON" by default from factory or did you activate it via VCDS ?

Bro were you able to activate this on your vento ? If this actually works with stock cluster then would it be also be possible to activate this on pre facelift polos ?

Cheers.

Did you use the software that came along with the cable?

[quote=rana_kirti;3491141]so cool. was the needle sweep on ignition "ON" by default from factory or did you activate it via VCDS ?



The needle sweep came activated from the factory. Sweeps on ignition on.

Can you shed some light on what exactly is the 9w2 Bluetooth module? Does this basically activate bluetooth in your car?

Correct me if i'm wrong, but what i've understood here is that your car did not come with bluetooth and you managed to activate it with the VCDS?

Just wanted to confirm that "needle sweep" works with the Polo stock cluster in the GT models(maybe in the other models as well but I have not tried it). Its located in VCDS as "indicator celebration" and not as "staging"
