Your engine requires a lubricant that is approved to either 502.00 or 504.00

The only VW standard that Elf lubricants with an SAE grade of 10W-40 (there are several) are approved for, is 501.01 (petrol) and 505.00 (diesel).

Elf Competition SM 10W-40 (if that is what the mechanic used) is not one of those products - it is not on any one of VW's list of approved lubricants (to date).
