T5.1 2.0 TDI 100k CAAB
We only use the van for trips, and I've noticed a tapping noise that's got gradually worse over the last few months.
On checking under the he bonnet to try and locate the sound I opened the oil cap, and it was immediately clearer/louder.
There also what looks like exhaust gases, pumping out in time with the noise.
Other than the noise, there's no other indicator that something is wrong.
No warning lights or fault codes on VCDS.
Drivers well, no loss of power.
Just done two engine flushes, it's running fresh oil, and is regularly serviced.
So far, the shortlist of potential problems is:
- Damaged Camshaft, followers, lobes
- Sticky Lifters
- EGR valve stuck open
Appreciate any help narrowing down the cause. Will probably get it booked into VW for a diagnosis next week. Thanks
