On acceleration of mostly 2/3/4 there is a pinking sound going on so the garage think it is.
they told me to use shell v power in stead of supermarket fuel and that might fix it if not might be a knock sensor all guessing.
I'm waiting to run the tank down before trying that just wondering if there a known issue to cause this ?
its the xe1 engine petrol 85k (zafira b petrol)
Serviced a year ago.
Spark plug tips are white. Oil level fine.
water pump working
aux tensioner has no play
I scanned some live data that may help change the file extension from .txt to .csv to view

With any luck someone who understands what to look for in live data may be able to find out whats up.
I've filled up with shell v power (97 octane) and done about 13 miles and has made no difference.
The only fault code is for a brake light switch which the local garage said to ignore as the brake lights work.
Appreciate any help.
