MY21 Wolfsburg V6 Moonlight Blue
The jerkiness issue aside, that's been reported by some launch owners, the root cause of which is yet to be formally ascertained(maybe it's the lifters as pointed to above), I don't think there's a cooling issue as such, it's the way the car has been designed with ecu managing it all. Why would you want the gearbox to be cooled upon startup rather than designing it to ensure it gets to optimum temp asap, same how engine cooling is designed.Thanks for the explanation Singh, as usual very concise and helpful.
So in your opinion is the engine and transmission cooling system on the CR Touareg up to the job? I must say I become concerned when I see the engine oil temp running at 120C or above.
I note that in my case the 190KW engine is the same as that used in the Amarok but for clearance reasons I guess, the oil pan capacity is significantly reduced. This can’t be good practice for engine longevity! Should owners planning on long ownership install extra cooling for both?
I also agree that the current CRV8 is of Bentayga origin but the V6 is Audi design and used in many VW Group vehicles.
Has there been any transmission, gearbox failure due to overheating, I don't think so. Has any touareg karked it whilst pulling a Bruderx(or a Jayco)? Nope.
So far it's temp anxiety rather than any performance issue, loss or degradation.
Is the jerkiness attributed to how gearbox cooling is designed I don't think so. My closest guess is mechatronic still, but I could be easily wrong as there's report above re lifters, valves being the issue. (Worth investigating if lifter part numbers have changed over the years)
The only change made in two years to the design of the CR related to cooling that I know of is the front side ports are open from my21.
Do we have enough information relating to this change for my21 vs my19 Touareg pulling the same weight to see if this makes a difference to temps I don't know.
So, from my perspective put aside temp anxiety and enjoy driving 😉
