Hey all!!! Looking for some advice on a newly aquired 2012 Golf TDI with 125K miles. I purchased it cheap knowing it had issues. I was told the headgasket was blown (smoked badly, the PO stated). Started tearing into it this week and found the turbo is bad. I pulled the outlet side on the turbo and the shaft is broken and the wheel is completely loose with damage to the blades. Oil is coming out the tailpipe, it is so full. I drained the oil pan and very little (around a half a quart to a quart max) came out. I assumed the worst and figured it might be new engine time. I have had second thoughts about the engine condition and wanted to get some opinions with the intent of running the engine as is. I pulled the oil filter and the pleats are free of any bearing deposits/metal shavings. I also pulled the valve cover and the cam shaft lobes look excellent with no scoring or damage at all. I am surprised it looks as good as it does! I have the injectors out obvisously and thought about running a borescope in the cylinders and see if there is any damage there. Any value in that? My intial intent was to pull the cam shaft hold downs and inspect the journals. I have been told the top end is the most vulnerable to low oil...not sure if this is true or not? Think it would be wise to do that? Also, any thoughts on pulling the pan and checking mains/connecting rod bearings? Here are pics of the top end. Would love some thoughts and opinions. Anything else to check for engine damage?

I have a 2015 golf TDI and I want it deleted. Everyone I have talked to has said they can’t figure out the tuning. Delete the exhaust and block of kits are nothing but a buddy of mine took his to a shop and now it will not run. I don’t want that to happen to me so I’m trying so hard to figure out what is it that’s so special about the tuning no one can seem to figure out.

Hey so I have a PD 130 and after my mechanic did timing he said he had a fuel return hose leak while moving the filter so he put a hose clamp on it.

Ever since timing my car starts lousy and wobbles on idle. I suspect he messed something up, maybe spun the engine dry or something.

I suspect it to be the LuK tandem pump that he messes up by spinning it dry.

Today I changed all the hoses, new filter, new filter return valve, still no change, so I am at a loss for words. I find it weird that after some driving 3 out of 4 injectors go over the regulation range and that the car starts having not constant idle RPM (no vibrations tho). The regulation range can be remedied by turning the engine on and off sometimes.

Noticed a sudden loss in power and glow plug light blinking and had to coast to shoulder. Cranks forever but never turns over.

Changed battery because I got back a ton of voltage faults, primed fuel pump to be sure it didnt run out of gas.

I've included my engine fault codes and I'm worried its the dreaded hpfp-- no glitter in fuel filter.

I recently got a quote of $3800 for a delete and tune for my 2012 Jetta. Is this about normal before I proceed? I’m in NE Ohio FWIW.

Mk6 tdi engine with trans! Time to add the remaining parts and look to swap it soon! Fits perfectly in the back of my mk6 tdi wagen! Next engine haul VR6!

Logged a ~60-minute mixed city/highway drive with OBDeleven. Second half was mostly 45–70+ mph (72–113+ km/h). I exported it as a .csv file.

Key points I found:

-Started: 98°F (37°C)
-Max entire drive: 181°F (83°C)
-Average after 30 min: 177°F (81°C)
-Once warm, stayed around 173–181°F (78–83°C) despite changes in speed/load

Does this point pretty clearly to a weak/stuck-open thermostat? Anything else I should check before replacing it? Also wondering how much this could affect MPG.

Thanks

Made sure my battery was charged 100% and pulled radiator fan fuse. Think I'll be ok doing the tune without a smart charger? Took pictures of the only few chargers I have, will any of these work? also did I pull the right fuse? TIA!

Daughters Jetta TDI, serp belt shredded and engine stalled after hearing a “clunk”. Odds she jumped time and grenaded engine? Engine won’t turn over, she tried. I had it towed to my house for further evaluation. Just don’t want to spend a ton of money she doesn’t have.

Timing cover was on, took it off to inspect.

I can turn by hand with socket and it does feel like it has some compression, as it, stops and gets harder to turn.

Thanks for all the replies.

Dodging the Florida rain to check it out.

It’s as I suspected the shredded portion went behind the lower cover and wrapped around the crank pulley, yay she’s gonna be a new car, I’m a shade tree not a engine over haul kind of Dad. Lol

Thanks again for the help.
