I have just changed landys from a 90 to a 90 defender tdi. whilst I am pleased with the extra power on hills(as I live in wales this is v usefull) I find it very sluggish from cold. I live at the bottom of a hill and when I try to get out first thing I have to go v slow in first gear and when I change to second I virtually lose all power to the point of stalling, it really struggles to get up the hill, then after about a half a mile suddenly has a powere surge and everything is fine. Any help would be great as I am not used to tdi's and thier ways
