Limp Mode from IAT

hotshotrob · 05-29-2017, 02:00 PM

Hey guys, this has been happening ot me even before I went FBO. I will do a nice pull on the highway and few minutes later car goes into limp mode stating drivetrain malfunction. Now that I have jb4 to read my codes it is spitting out "108C01 charge air temperature, plausibility: temperature too high" When I check on the IAT it is over 177F! damn hot, especially when ambient temperature is reading around 78F. Has anyone else experienced this issue before?

It's either installed incorrectly or a faulty module. Had the same issue with Dinan.

I was getting the 20A201 error code also. It has to do with Intercooler being low on water. Found the Intercooler reservoir was low and the Coolant reservoir was low also. Topped it with with about 1 liter of distilled water. It is possible I have a leak. Car is going in on Friday. I would check to see if its low and top off.

20A201 - Charge air cooling system: Protection function Coolant pump active due to dry running.

Yal called it, coolant was low. Came on boost hard this morning and never went over 90F!
