Hello everyone. This is my first post on the forum even though I am a long time reader, so please be friendly to me

 

I have two recurring issues with my Octavia. First is that the coolant warning light on the dash comes on but I cannot find any problems. The fault seems to be triggered by cold & damp weather. When the weather is warm & mild like we have been having in the UK recently, there is no coolant warning light when I have started the car after not using it from the previous day. However, when I start up the car around when the weather is cold + damp say around 0530 hrs, then the coolant light comes on. I have checked the coolant levels & all is fine. No leaks either, & the engine temperature is always stable + never overheats. 

 

The 2nd issue I have is a screeching metallic sound coming from the rear nearside wheel when steering either direction. It only happens from cold when I start up the car, but after around 5 minutes it is gone. 

 

I have had the car looked at by the dealership I bought it from & they cannot find anything wrong. I bought it 2nd hand back in November 2016 & it has another 6 months warranty left. I have booked it in with the dealership again to take a look at these issues which keep on happening. If anybody has any ideas about what they could be then please let me know. Cheers. 

 

1. replace coolant tank, or scrape the two prongs with a long screwdriver or similar.

 

2. Disassemble rear brake disc pads from slides and clean up surfaces and re-assemble with a little ceretec grease.  Inspect pads / discs while you are there for wear and make sure handbrake mechanism is releasing properly.

Thanks for the reply. I just hope the dealership are looking at the problems properly rather than just a visual check. 

 

For 1. the latter would be best to try first imo. Also I have heard it could be related to a water pump issue which I am hoping it is not. I will update when it has been to the dealership. Cheers. 

 

Mine did it too. Lots of others have as well. If your level is not dropping, and your car is normal temp, I doubt you have a cooling system problem.  Give the prongs a good scrape on all the surfaces you can reach. Solved my issue.
