How did you ascertain that your " Haldex etc all good." ? 

 

The best way to tell if your haldex and transer case/bevel box are functioning correctly is to take off hard on a low traction surface while someone outside the car observes if both front and back wheels are spinning.  If only the front wheels are spinning then you have an AWD problem (and that could cause lots of traction issues/lights etc when driving "semi-normally").

 

If you have proper AWD functioning but are still getting lots of traction warning lights I'd have to suspect that maybe your tyres are worn/crap, and/or the roads are wet, cold & slippery, and/or you are driving significantly too fast for the conditions.

 

Also I strongly suggest leaving ESP active when driving on public roads (ie don't long press the traction control button).  If you have a crash with ESP disabled (and disabling ESP makes it MUCH more likely that you will lose control & crash) then it is quite possible that a crash investigator may check, find out what you did contributed to the crash, and possibly deny insurance coverage and/or cause traffic charges to be laid against you for disabling a car's safety feature.  Even experienced race car driving instructors tell their students to leave ESP enabled on race tracks

[edit:  on most cars, but VW's may overheat brakes on some circuits if car senses a possible "loss of control" situation).]

Thanks for the replies. Looks like I may have to live with those pesky yellow lights. Maybe the VCDS option for ESP Sport won't provoke them... .

Even that turns them on, proper PITA as I would love to turn TC off permanently.

Off topic, but ESP needs to be turned off on a track for all but a novice track driver as it can cause brake fade and/or boil the fluid as it has to work overtime on a track. I'm led to believe that ESP will still kick in if it needs to if you get completely out of shape.

 

Agree for the road, but TC and ESP are two very different animals.

TC/ESP is now in sport, not disabled so half off I guess. Full Haldex service and new pump a few months ago. Tyres about 4.5mm all round. Far less TC intervention in sport so it's not a grip issue, rather I feel it's some innate quirk of the VW system that doesn't handle extra power particularly well. The car is now much sharper on the throttle. It's interesting how much more intrusive the ESP is in the Golf than my RWD E63s, but there you go. 

 

Thanks again for your replies all, very helpful.
