Knock/scraping in first few minutes at first startup
My TS lusso has started making a strange noise at startup. It is almost like a knocking/scraping noise occuring two to three times a second and which lasts for about two to three minutes when the car is first started up on a particular day. It will not make it at subsequent start ups unless it has cooled down for atleast half a day.
It is really bugging me because just sounds awful. The car runs and sounds ok when warmed up and got me to and from Dorset from Essex last weekend without any problems (apart from burning a fair bit of oil as expected).
Had all the belts, tensioners and variator replaced recently as it was due anyway but had no effect on the noise.
Anyone have any ideas?
