Hi guys, hope you can help to see if you have come across this issue before?
We have a 2015 mk3 Octavia with the 2.0Tdi engine (CRMB) and every now and then when driving the car will hick up (like it's trying to go in limp mode for 1 sec) and a red warning will display for a sec (sometimes not long enough to read) stating please stop engine overheating!
Now the water pump has been replaced with the revised genuine pump, the coolant temp sensor has been replaced genuine.
There are no codes stored in the ECU.
With live data on the car such as:
Coolant temp
Rad temp
Oil temp
ECU temp
Intake temp
All are in spec and when the warning displays there are no temperatures spikes!
Any one come across this?
