Volkswagen parts reviews

Just picked up another 4 Ruthiums from rock auto, can't beat $8 a plug.

The new cylinder head fixed the smoking, I haven't had any issues since.

Anyway, the only 508.00 spec oil I've found locally has been this Mobil 1 ESP X2 at Wally World. (walmart) Anyone else running it? Anyone seen any deep analyses? I put lots of Mobil 1 Delvac through 2 TDIs totalling 485k miles, so I'm willing to bet on this Mobil 1. I like being able to pick it up locally, and at only $28 for 5 quarts!?

I then removed the existing heater core and replaced it with the new one (Nissens) and checked for leaks in the coolant system using my coolant vacuum. I had no pressure leak offs after 1hr., 15min. so I assumed since it was holding pressure there was no leaks.

I also am getting my cylinder head replaced under warranty for a 2020 GLI due to the smoke on startup. I had my PCV valve replaced around 14k miles, then did the valve stem seals and both worked for only a few thousand miles. Now the dealership wants to replace the head.

If they are anywhere close to as bad as the Kumhos that came on my GLI, your not going to have a good time. Get some Michelin Cross Climate 2s. they are supposed to be the best all around tire available.

I decided to give the NGK Rutheniums a try earlier this year after reading about them on this thread I've been happy with them so far, the engine ran noticeably smoother than with the old plugs (but that could have also been simply due to new plugs).

That’s curious….. if you look closely at the end of the shorter plug you can see another set of threads, it looks like there an insert threaded onto that spark plug. It would appear that it wouldn’t be sitting where it needs to in the combustion chamber so that may explain your misfire.

My wife's has had electronic gremlins since we got it in '21 (it's a MY22).

-Passenger seat heating mat and occupancy sensor was causing codes and had to be replaced (1 week in shop).

-In-tank fuel pump has been replaced twice on recall.

-Some other recall thing that caused it to randomly go into limp mode (1 week in shop).

My 2012 GTI has 175,000 Kms and is on Water pump #4.
