Recently I had a problem in my linea Di where the engine oil and coolant oil has mixed up due to an internal leak in the cooler unit . I understand in many cases under this situation the engine get overheated and seizes:evil: ( fortunately or unfortunately engine seizure did not happen in my case). In these cases the engine is overhauled / replaced. Suppose the engine is under fag end of warranty (e.g. ur left with 3 months) and the following scenario is proposed by the company. (a) the company suggests that the defective cooling unit will be replaced and you can use the same engine In case of scenario#a where only the defective part is replaced. You do not know what is the damaged caused to the engine parts esp head gasket. damage to head gasket also can also lead to a similar mix up oils in future. (b) Replaces with a new engine In case of this scenario. What happens to the (1) engine warranty- will it be for next two yrs or for 3 months only (2) Extended Warranty (3) Vehicle registration where VIN number is mentioned. I would like to request fellow tfians to provide their take on these scenarios which would be helpful for me (facing the situation now) as well as for others in future.
