Tried a search but couldn't find anything specific to the A/S3. Has anyone had this done ? Wondering what the recommended service interval is and what people have paid to have this done at either Audi or an independent ? I'm thinking it's not practical to do at home ? I've just been quoted £180 by a VAG specialist - is that about right ? My car has done 30k and is stage 2 tuned and also has a TCU map so I'm thinking it wouldn't do any harm. It's had 3 oil changes, brake fluid has been replaced twice and Haldex fluid once so it's only ATF that's not been changed. Thanks in advance !
