Title: Screeching noise
Post by: Youngie on March 13, 2020, 22:37:59: Hi Guys,

I recently bought my i30 for a run around for work. I have encountered a very annoying issue with it and looking for some help to solve the problem,

When i turn the car on there is a screeching sound, this normally last a few minutes when idle, it goes away and comes back so i got a new drive belt and tensioner pulley fitted.

After 2 days the screeching is back and is louder and constand, it does go away no matter how long i drive for, seems to increase when i accelerate. Anybody have some soloutions to get this to stop before i get a massive bill from a garage.

I know very little about cars

Thanks

What does mech say ??
Manual or auto ?

Said its just a process off elimination! It could be either one of the pullys? Once the tensioner and new belt were on it stopped the noise for a day or 2 and then it came back

It is very intermittent, has done it about 4 times in the last 6 months. Mentioned it when it went in for a recent service but they didn't find anything other than loose heatshield. Very difficult to diagnose what it is because it happens so rarely. It didn't sound as though it was coming from the drive belt end of the engine.
