Hi @asifk
I use tiptronic from Fewbie+ onwards on all my drive, i drive mostly on 2nd gear and for difficult climb and gaining some momentum where ever required shift to 1st gear. And additional to that i have fixed a push in fan and changed my engine oil to Mobil 1. I never had heating issue after this, some time when we stuck the temp will rise up little bit, but never worry just switch off the AC and drive a little bit further and it will come back to normal condition. Usually the temperature will increase when u use AC and the car is not moving, that will some what solve my fixing the additional push in Fan.
