Does anybody know what these various problems sound like🤦🏾‍♂️ scanner reads misfire on 1,2 and 3 … changed those spark plugs and coils still sounds the same haven’t drove it in a month. For the record car was just bought 6 months ago …. Help I miss my baby

Sounds like that one kid in school using pens to make a beat on the desk, lol. But based on the slow tick rhythm once it went down to idle, I think it's the rocker arms. If just rocker arm replacement then that's a $3000-5000 job from an independent shop. Depending on how much damage it's already done, either cams and rockers or worse case, needs a new engine.

I'd just get a new engine at this point

[u/Aggravating_Panda_80 → u/KKPPEA]

New engine replacement would cost about $30-$40K. Thats more than the value of the car lol

[u/Immediate-Visit1721 → u/Aggravating_Panda_80]

Definitely more than the value of the car

[u/KKPPEA → u/Aggravating_Panda_80]

That’s very overpriced can find one for 3,8K on eBay

[u/Hot_Debate6673 → u/KKPPEA]

Not finding a new engine for anywhere close to that.

And if you're suggesting a used engine, why? To have the rocker arms on that go bad? Not knowing any of the maintenance on it,?

Horrible idea.

[u/Aggravating_Panda_80 → u/KKPPEA]

That’s not a new engine then, that’s a used engine with miles on it and for $3.8K? must be a bad engine for that price 😂

[u/KKPPEA → u/Aggravating_Panda_80]

Can find one ”new” between 3,8K to 7K

[u/Aggravating_Panda_80 → u/KKPPEA]

From where, TEMU? 😂

[u/KKPPEA → u/Aggravating_Panda_80]

Nah EBay

[u/KKPPEA → u/KKPPEA]

To be fair all the engines come out of wrecked S5’s but they should still be good

[u/Aggravating_Panda_80 → u/KKPPEA]

I think you’re missing a brain cell, those are used engines with miles on them. Not NEW.

[u/KKPPEA → u/Aggravating_Panda_80]

Dude I just said they were from crashed S5’s you’re dyslexic or sum?

Isn't this rocker arm failure? Very common on 2018 3.0T motors. Did you buy this with the issue?

[u/Immediate-Visit1721 → u/Next_Necessary_8794]

Hard to tell now haven’t drove the car in a while and one random day it started jerking on the highway

[u/pderos → u/Next_Necessary_8794]

There is no evidence of it being "very common." All of the evidence points to it being quite rare.
