Hi,

I have a 60 reg (MY11) 1.8tsi I have owned since 2016.

 

Prior to my ownership, it had an engine swapped out in early 2014, as the timing chain tensioner likely failed and caused a catastrophic engine failure.

 

Now I'm assuming, and someone cam correct me if I'm wrong, the peripherals like water pump etc, would have been swapped from the old engine to the new one during the swap in 2014.

 

If that's the case then I might need to start looking at replacing the water pump? (8 years old).

 

Reason I'm saying this is that over the past 6 months, I've had a couple of red thermometer errors on startup, that have cleared when I have restarted.

 

I suppose theres always the possibility it might be the temp sensor or connection as well.... Excuse me while I deliberate.

 

Anyway, what do you the sage and wise think...

 

It will be the coolant level sensor in the header tank. The prongs get furred up and start giving spurious check coolant warnings. Start by giving the prongs a scrape with a flat blade screw driver.

i wouldn't worry about the water pump until it starts leaking.

 

Probably best to diagnose what the warning light issue is rather than firing the parts cannon at it.
