I’m having some trouble with this one. Sure, some of the repairs are quicker/easier if you part swap (like the struts), but 4 steering links? Unless they’re actually something else and just being called steering links…
OP did say it was an independent. Do you have any mechanical ability at all? Or know a buddy who does? A 6-pack (or bottle of wine, or whatever) buys a lot of time with friends.
Also odd that both horns are out. One I could see, both seems strange to me. If there’s an electrical problem that blew them, or they’ve both been exposed to an extreme amount of snow/ice/salt, then maybe. Make sure they’re actually dead. Use some sort of wire and jump from the battery directly to the wire connection on the horn…if they blow, then it’s not the horns. You can get used horns from a yard for as little as $15 - and some yards will pull them for you. $110 sounds awfully high, even for dealer prices.
Unless there’s something wrong, you don’t NEED a cooling system flush. Wipe that off the books. You CAN do it, but it’s not required…not yet, anyway. With very little mechanical knowledge and a bucket you can drain the radiator, and top it off with new coolant from a dealer. You shoulnd’t need more than that. A flush isn’t necessarily the best way to go in any event.
Sorry…I find this a disturbing post. I’m also a VW fan, and drive and work on a few.
