I’m pretty sure I read somewhere on here that they had cracked the Bosch ecu on the 6.1’s and can now be remapped ?
Not sure at all Personally I do not like HALDEX I would much prefer a Torsen / Ferguson limited slip geared differential with permanent 4WD HALDEX is a pit in the arse design that is not very reliable or fool proof and needs religious maintenance oil changes etc I have no idea if our vehicles are adapted to use it, making the vehicles slow to respond to an instant instruction by the right foot to go and why it has to THINK ABOUT IT FIRST. You are the first person that I have heard complain in a manual 4Motion so perhaps it is something else that is going on. What engine do you have and what power? Is your vehicle jsut uinderpowered or does it struggle to pull away in that very first instance making you choose not to proceed with pulling out for instance. Is it that very fisrt instance you saying go the vehicle ponders then goes?
OK thank you for qualifying that it must be only the DSG vehicles that hesitate to pull away initially from stopped as was previously thought One is waiting at a busy junction see a gap plant foot on accelerator, nothing happens, have never measured the actual time delay, probably less then a second but it feels longer one then may abort the attempt to pull away because the opportunity has gone to perform it safely. Once going if one decides to proceed it is fine it is just that initial delay which is believed to affect only DSG 4Motion vehicles and I think regardless of engine?
It has been cracked, but the ECU needs to be sent away (to somewhere in France) and the turnaround is far from instantaneous - they need it for something like a week or two.
If you thought the performance was an issue why buy it?
Yes we do. And really changes the characteristics of the gearbox - How it should have been out of the factory.
I would go along with what you say but I think it may be worse in 4Motions possibly, I have heard some other 4Motion DSG notice the delay . This Carevelle 4Motion is the first DSG I have driven though have owned conventional automatic such as the Touareg 5.0 litre which had non of that and also provide loads of engine braking also which seemingly the DSG does not provide even when paddling down sever gears on down hill slopes.
@skyrunner123 Did you work out if it’s just the accelerator kick-down resistance (yes, manual and DSG variants all have them)?
My T6.1 manual 150 22 plate (owned from new) does exactly the same as you describe.
