Took my car to a Mavis to get a tyre replaced. Whilst it was jacked up they brought it to my attention that my shocks show signs of leaking and needed replacing. I figured it's an upsell, they checked the computer several times - presumably for stock availability, before chatting to me about it. It's a 2016 A3 with 90k miles on the clock. It's only driven about 5k-10k miles a year but we are in New Jersey which has notorious pot holes. I'm happy to have my mechanic do this if it's necessary. My annual service is coming up this month. Are there any obvious signs looking at the photos?
