JSS Motorworkz is an independent car workshop in Toh Guan, Clementi, that specialises in European and Japanese cars, with a focus on German makes such as BMW, Mercedes-Benz, Audi and Volkswagen. Its best-known work is engine and gearbox repair and overhaul, backed by advanced diagnostic tools. Other services listed include engine carbon cleaning, injector cleaning, servicing, accident repairs with insurance claims handled, and car sales and consignment. The website says it is the official servicing partner of CarVault Singapore, and it opened in November 2022.
Customers who write about it praise the thorough checks and the clear, honest explanations of what is needed and what it costs. One owner says a fault that other workshops had failed to fix for three years was finally sorted, and several reviews say the staff do not push extra work. Walnut blasting is a common job, and owners of Mercedes cars mention it often. One reviewer gave a one-star review after walnut blasting on a Mercedes, saying the work did not go well, so it is a mixed picture on that job.
The workshop is open Monday to Saturday from 9am to 6pm, and the unit is number 02-140 in the building. Within a kilometre there are 60 other mechanics. Our pick in Clementi for a careful diagnosis on a German car.
