Is it safe / advisable to get the cambelt changed by a non VW garage? Are there any special tools needed etc that only VW would have? Reason I ask is a guy at work got his renualt laguna serviced from a mobile guy and had his cambelt done too (one of those guys that comes to your work). He later read in the Haynes Manual that a special tool is required to tighten the cambelt, which he thinks this mobile guy couldn't have had.
Cheers.
