Thanks, I have ordered from them before and seems like a great place to save some $$$. Until I can get the car into the shop(next tues), i've been monitoring the engine temp from the "Hidden menu #7" and carly app. I'm trying to confirm that my thermostat is faulty as the other day i noticed a temp of 85 but then quickly dropped back to 70. With winter approaching the outdoor temps have been around 0deg C and on my 30 min drive this morning my temp was still at 70. Could there be another factor the engine temp is not rising if say the thermostat IS working properly (I have a fault for egr cooler bypass valve does not open). I have noticed the vacuum line for the valve is a very poor fitting but also cannot budge the valve by hand.
