Tesco 99 solves rattle?????
So ive had a nasty rattle on stary up for about 4 weeks now, yes, I know it could be the variator...........ive already had 4 in my 2001 156 Sportwagon but it only happens every now and again maybe once in every 10 start ups, not always when its cold but even when the engine is hot.
So if its not the variator it could be a loose or cracked exhaust heat shield, checked that and all seems well..........so wait for this.......decided to treat the engine to 2 full tanks of Tesco 99 unleaded..........and the rattle has disappeared.
So is this just coincidence or is it likely to have anything to do with the superunleaded?
