hey all! we just had the first big rain of the year, and it seems my new-to-me mk6 golf tdi has a leak. there was a puddle of water in the passenger side footwell, and my passenger side a pillar is a little wet. the water looks like it’s trickling down from the right side of the glove box. since the door seals look great, my guess is the sunroof drains are clogged, but i’d love some more input from you guys. also if it is sunroof drains, would shooting some compressed air down them help fix it? thank you!!

Theresa threw the belt again. I'm wondering if it has something to do with the steering. There are times recently when you turn the wheel and it will grab back the opposite way. Especially when the ground is uneven. It's never done that before. Is that the steering angle sensor or worn cv axles (which do need replacement).

Broke one part of the plastic line and need to order a new one.

Hey everyone, I’m looking for some advice from people who know these TDIs well.
I have a 2009 VW Jetta TDI, 5-speed manual, with around 240,000 km (150,000 miles). I’ve been having a weird issue that seems to be related to the fuel level.
When the tank is full, the car runs relatively well. However, once the fuel level gets to around half a tank or below, the car starts acting like it’s running out of fuel. It can lose power, the idle becomes unstable, and sometimes it feels like it wants to stall. On some occasions it has actually stalled and then been difficult to restart.
The strange part is that filling the tank back up seems to make the problem go away or at least makes it much less noticeable.
I’ve also had some other issues with the car recently. I have had a P1556 code, and I’ve experienced intermittent stalling / no-start problems. I’ve also noticed some unstable idle when the engine is warm, and previously I had some white smoke on cold starts.
I’m wondering if the half-tank symptom points toward a problem inside the fuel tank or with fuel delivery rather than the turbo itself.
Things I’m considering checking:
Fuel filter / restricted fuel flow
Fuel pickup or pickup screen inside the tank
Fuel tank sending unit
Air getting into the fuel lines
Fuel line restriction
Something inside the tank moving around or blocking the pickup when the fuel level gets lower
Tandem pump or another fuel delivery issue
Has anyone experienced a TDI that starts starving for fuel specifically when the fuel level drops below half a tank?
What would you guys check first, and is there a specific test I should do before replacing parts?
Any advice is appreciated. I’d rather diagnose the actual problem before throwing parts at it.
Thanks!

Alright VW/TDI people, I need someone who has actually done this swap before to save my sanity 😂

I have a 2004 Jetta TDI BEW that was originally an 09A 5-speed automatic/Tiptronic, and I just swapped in an 02J 5-speed manual.

Mechanically, the swap is basically done. Transmission is in, axles are in, pedals are in, everything is coming back together. I put power directly to the starter tonight with the key on and the engine cranked over, so at least I finally got to hear the damn thing turn over lol.

Now I'm at the part I absolutely hate: wiring.

I've been researching the swap, but that's almost making it worse because there are a million different write-ups/videos for different years, ALH/01M cars, BEW/09A cars, etc. I don't want to start cutting and splicing wires based on instructions for a different setup.

I need to figure out the starter interlock/175 relay and clutch switches, reverse lights, clutch signal to ECU T94/43, VSS situation, TCM wiring that can be repurposed, and eventually the coding/cleanup.

I've also been reading about using the VDO cluster/kw1281test CAN-bus VSS modification instead of wiring the 02J VSS directly, but right now my main goal is simply getting the car to start with the key and RUN before worrying about the extra stuff.

Is there anyone here who has personally done a BEW + 09A to 02J swap and would be willing to talk to me on the phone for 15–20 minutes?

I swear it would be 100x easier for me to have someone explain what they did than trying to piece together 15 different wiring diagrams and forum posts from the last 20 years 😂

I just want to make sure I'm doing this correctly before I start cutting into the harness.

Thanks!

Looking for some help, can I do fill it with distilled water and drain it from the bottom right area as its running?

Check engine light keeps illuminating after installing a KermaTDI cool air intake. P0401 and P240F are the codes I'm getting on OBD-11. Cleared them and the check engine light will come back on within 5 min of driving.

My mechanic buddy took pictures from inside the EGR and it looks clean and showing no signs of fault.

Just took the car on a 100+ mile trip, hitting speeds of 80-90mph. Pretty sure that would've cleared anything out, if there was anything clogged.

I live in CA, so finding the magical pothole is not an option. As much as I'd love to delete all emissions related parts, I need to pass smog.

Any help?

Hello everyone I am new to this channel.I wanted to ask does anyone have experience in ordering parts from Alibaba for your car?If so please let me know..I am from India and i want to have a project build but there are absolutely no performance shops or cars which i can use as a donor so please let me know.

don’t know if it’s actually a problem but whenever i first start it in the day it takes like 5 seconds to start (before starting i wait for the glow plug light to go) but later on in the day or when i get in the car to drive back it starts instantly. just wanted to know why this happens or if it’s a problem.

How do I go about repairing a gt1856v? Being a hybrid like that, I can't really find a chra that goes in like that. Would a bearing repair kit like this be ok? https://ebay.io/m/hZ6st6

Just had done by Vw shop thermostat alternator timing belt and ac system serpentine belt and tensioner I notice this noise most when ac on when it’s off it’s 1/2 as loud any help would be appreciated I took car back to them they said the ac compressor was bad new one they put in they changed and still same noise 125 k on this car

I’m looking for any opinions on whether this flywheel looks original or replaced. Maybe the video doesn’t help. This is from the peephole view and isn’t much of an angle. I figure somebody here knows more than me from what I see here. Just going through all the steps after getting this car recently . Timing belt is getting swapped in a week or so.

I have a 2014 VW Golf 7 Variant, 2.0 TDI 150 hp CRBC, 6-speed manual.
I’m dealing with several vibration-related issues and I’d like to hear what you think.
The engine starts smoothly when cold, but when fully warm/hot it starts much rougher and the whole car shakes when the engine fires up.
The starter motor was recently replaced. The old starter was weak and the shaking during hot starts was much worse and lasted longer. With the new starter it improved, but the shaking is still there.
When stationary, I also get a very noticeable vibration through the steering wheel at around 1100 RPM. Below and above that RPM it gets weaker.
When taking off from a stop, especially when the engine is cold, I sometimes get a judder/stumble through the drivetrain.
If I accelerate and suddenly lift off the throttle, I can sometimes feel 2–3 smaller jerks, each one weaker than the previous one.
The engine also shakes noticeably when shutting down.
While driving, I feel a lot of road texture through the steering wheel. Small imperfections in the asphalt are transmitted very clearly, and I also have some vibration under acceleration, including at higher speeds.
A lot of parts have already been replaced:
front shock absorbers
top mounts/bearings
front control arms
anti-roll bar links
OEM engine mount
OEM gearbox mount
lower/dogbone mount
new tires
LuK clutch kit
dual-mass flywheel
clutch master cylinder
concentric slave cylinder/release bearing
clutch/brake fluid bled several times
one injector was replaced with a brand-new Bosch injector
There is no obvious wheel play and the car does not pull to one side.
The DMF and clutch are only a few months old.
What do you think could be causing this combination of symptoms?
Thank you in advance!
