hi my car has the usual coolant temp sensor issues,from cold it starts spot on but after say a couple of mins it has a bad idle where it nearly cuts out then the revs will shoot back up to a thousand rpm,the car is running rich and it drinks fuel,also takes ages to get to 90 degrees,and doesn't like starting when it gets hot,now going through my receipts it's had a coolant temp sensor that was bought in June this year and it's a dansk europarts jobby,would these cheap ass coolant temp sensors really fail after such a short time,I'm picking a fibi one up tomorrow from my local vw parts specialist just to rule this out,what do you guys think
