Sent my car (12yo Audi A6) in as it was vibrating noisily and needed servicing for Vicom inspection. Parts needed changing include engine mounting set, headlamp including control module and parts. Servicing was completed with worn parts replaced as well. All in all, a great and professional job for the price paid. Recommended.
