Welcome to another video. If you want to get in touch with us check our website www.vagtechnic.uk In today's video we have an Audi S4 B8.5 with CRE 3.0TFSI engine . Coolant leak occurs from the front of the engine so typical job for us ... water pump , thermostat , pipes and PCV . Owner wanted to clean the intake valves from carbon as well and this is how they look after 100k . Next car is a freshly imported Audi RS4 B7 from Japan . We also have a UK one on the ramp for a bigger job so why not to compare them Thank you for watching
