Does this seem like a normal temperature for a stock 2014 Passat DSG ea189?
I just purchased this 2014 Passat DSG (after doing the buyback on my other 2014 Passat DSG), installed my polarfis and noticed higher than normal temps when compared to my old 2014. I then plugged the VCDS into the car to verify these temps were accurate and sure enough they were. I took it to a dealer to make sure the system was running correctly and told them about the high temps. They said all was normal, but when I got the car back, the temps were still getting to over 100 degrees Celsius, sometimes up to 103-104. So then for my own comparision, I measured (through VCDS) a 2012 jetta tdi and the highest temp that I saw under similar driving conditions was 86 degrees Celcius and that was during a regen.
When I took my car back to the dealer, I showed them this and they took my car on a 28 mile trip and logged temps every 4 miles. They then tested another car (a 2013 Passat DSG TDI) and got the same results, over 100 degrees Celsius. Also to note, it was 40 degrees outside when the dealer ran these logs.
I am able to get the temps up to ~100c just sitting in my driveway holding the car at 2k rpms. I am worried about how hot the car is running. Did VW mess with something causing these cars to run hotter when they did the fix? Something tuning would fix? Can anyone comment on this matter or tell me their coolant temps on a fixed ea189 passat?
Fast forward a week or so later and I look into the problem a little further and noticed high oil and egt temps. Oil is around 245f and egt's are 900f with little acceleration and 30 degree weather. Them seem to climb just barely hitting the pedal like during a regen. I can get it up to 1200f without any effort.
Car has 72k on it and I have owned it for about a month or so. Turbo was replaced by previous owner as stated in the carfax.
Any help or advice would be greatly appreciated.
