Hi,
Thanks for your prompt response. I guess “grinding” noise is not the most accurate description. It’s more of a rattling noise, like when an empty shopping cart rolls on a concrete pavement (but much lighter/softer). Other details:
- All the parts have been maintained/replaced according to the manual.
- There is a check engine light on.
- No engine oil loss.
- No smoke coming out of the pipe.
Thanks!
