time for an update, after much speculation on everything from variator to big ends, took it to a mechanic I know, not a dealer, not a specialist just a regular "we fix anything" and as to the knocking, he fixed it....balance shaft tensioner and a badly damaged belt. Replaced it with a brand new belt kit, even had the cam locking tool available , oil change and she is back on the road going like a boeing.
Still 3 issues to resolve,
the "injector" type indicator on the rev counter is on permanently..... though the car idles perfectly, temperature and fans are all working fine,,,
2. Air bag warning light remains on, though the passenger light works according to wether it is activated or not....
3: Radio is locked out, no code. It is the Alpine 932, have no idea if it even works and it can literally be replaced with a CD/Radio/MP3 player for a few bucks more than the cost of sending the OEM radio away in the hope that it even works after recoding
