1) Deutsche motors, kota damansara
2) Vagtechnik, Glenmarie

both are good experienced and cheap, Deutsche motors parts are slightly higher as they are original VW products, their parts come directly from VW service centers (but still much cheaper than u go to official SC punya cut throat price, usually 25-30% cheaper than official SC)

Vagtechnik parts is even cheaper but they are 'OEM products', still original but not sure whr they source it from (their parts around 20-30% cheaper than Deutsche motors, and arnd 50% cheaper than official SC)

for normal and major services, vagtechnik is cheaper too, they use liquimoly oil and its cheaper than deutsche motor's castrol edge, less than rm350 for vaghteknik and arnd 450 for deutsche motors for normal servis

and advise to go vagtecnik on weekdays, even on weekdays they are very crowded, go early or call for booking first before u go, walk in very susah as too many customers there
