Seeking Advice: Retire CC or Make the Repairs?

Have a 2012 CC at 140k miles. The check engine light came on and the car started to shake during ignition (went away when started driving). I changed the spark plugs and coils but the problem remained.

The shop is telling me I need a carbon cleaning, timing chain replacement, and camshaft reseal – all things I’m sure are due. It’s roughly ~$5k, making me question whether it’s worth repairing the car given its milage.

Was thinking about other major repairs that could come soon. I already replaced the transmission at 110k miles, but haven’t yet done the water pump or manifold, which would add another ~$2k.

I figure I’m betting $7k in fixes that the car will last another 40-60k miles. I don’t drive much so that could be 3+ years. Curious what others thing – is it worth putting the money into the car or cutting losses and getting another?

You seem to have direct injection . . . so I can see the decarboning at 140K

What I’m having a harder time accepting is timing chains at only 140K. Does it actually need it, is there noise, or what’s going on there?

As for this “camshaft reseal” . . . how bad is this leaking?

It concerns me you already had the transmission replaced at 110K, which seems very early to me

I’m guessing you’re taking this car to a VW dealer or an independent who specializes in that brand?

It might be wise to seek a 2nd opinion at another shop, imo

For expensive repairs it’s always a good idea to get a second opinion. Just describe the problem and don’t say anything about the other shop’s diagnosis. Get everything in writing for future reference.

Did you replace trans or rebuild it? Cost?

If I may ask, what engine and trim line do you have???

Something not adding up in my head and I need to look it up 1st before commenting on it…
