i have an issue with my Seat Leon 1.9 TDI 2008 retaining engine temperature.
I have performed an EGR delete using a blanking plate and it appears the warm up time now is now significantly slower than it was before.
Once the car reaches 90 (without the heaters on,) if I'm sat idling and then put the heaters on, the temperature starts to drop and doesn't stay at 90.
As soon as i turn the heaters off the temperature then rises back up to 90.
I have changed my thermostat to a Gates one however, i still have this issue.
Could it be the Coolant Temperature sensor that is faulty?
