Just resurrecting this thread.
My 2018 Skoda Kodiaq 1.4TSI (52,000 miles) has a very similar problem.
Had the timing belt done at 5yrs old as recommended.
A couple of weeks ago heard a noise but couldn't figure out what it was, noticed a significant oil leak a day or two.
Now in the garage (that did the timing belt) and here's the issue:
One bolt is missing (red arrow) and another is loose (orange arrow). The missing bolt must have been loose and backed out, then ground to smithereens as the pulley rotated. The remains are sitting in the housing (teal arrows). The pulley has been squirting out the empty bolt hole, the timing belt is soaked in it.
Think I need a replacement variable timing pulley and seal behind it, plus a new timing belt. Does that sound about right? (I'm not going to do this myself).
Second question - could this be related to the timing belt replacement 18 months ago? Sounds like it's an oil leak that causes the bolts to loosen, but that was not an issue previously.
The garage have just told me they don't want to do the work.... from what I've read, I'm wondering if they may be at fault or is at one of those things?
Thanks
