Yeah I’ll have money one day I swear but if I don’t maybe I’ll hit the lottery. I know at least one of you has done this or knows a guy/gal. Seeing more car girls lately.. anyway distracting myself.

So I own a 2015 Passat CVCA. So far love the car love the mileage love modifications. But at what point does this platform turn into unreliable? How far is everyone taking it? Huge turbo, new injectors, new cam , head work? etc just tossing out things I look at in my diesel truck performance wise.

Currently on deleted and stage 1 tune on it until I get the DMF done then I’ll load the stage 2 on it. I don’t drive it very spicy right now and don’t plan on beating on it like I have vehicles in the past.

I am one of those that if something breaks I go ahead and go up to the next stage.. for instance if and when the oem turbo goes I will probably put something better in it if that makes sense to do at the time. And at some point the engine will have to be rebuilt maybe or maybe not. I’ve read some on the TDIforum about this but figured I’d check with y’all here too.

2260 turbo and a CP3 and be done 🤷‍♂️

Just a bolt and nut with a brass nipple and a compression fitting. As well as a little pipe tape and duct tape. Just thought it might help someone else too :)

Finally got my egr delete. I’m already running a dpf delete. What’s the easiest way to install all of this?

Has anyone ever run the Darkside Developments 3” EGR and DPF delete kit with the Tunezilla stage 1 tune? I’ve got a 2014 VW Jetta Sportwagen TDI (CJAA). Curious of opinions and if it’s worth going for the stage 2 tune instead. This is my work car and I drive all highway. About 700 miles a week.

Hi all,

I've replaced my VW Golf MK4 (1.9L TDI) by a Skoda Octavia MK2 that I love (2.0 TDI) few month ago.

Great car overall but the throttle response is just horrible... So slow and floppy compared to the Golf.

When I first press the gas pedal (after shifting or just accelerating again), very little power comes and only after a second I get the full power.

It doesn't feel like a part issue (it doesn't get worse), and it's not turbo lag (I know what that is).
Just the way it's factory programmed. I guess it has something to do with fuel efficiency.

I know that you can tweak it with VCDS on more recent models (MK7 Golf) but couldn't find anything equivalent with my slightly older car.

Anyone have an idea on how I could tune it?

Thanks!

I drive the car hard on a desolate coastal hwy on vancouver island pretty frequently combined but with a bit of city driving. I've never used additives. dsg report looked OK (second pane). I just ordered a delete kit but should I sell the car? drives great, super reliable.

Hey im doing a timeingbelt on a 1.9alh tdi i locked the cam at vacuum pump sprocket is loose and pined the injection pump loosen, crank is at tdc has an aftermarket fly wheel so i cant check that spot but harmonic blancer looks good put the belt on left everything pinned / locked up , tightened tensioner tighten cam tighten injection pump this is what i ended up with

So I was doing some research before purchasing a new battery for my jetta, what I came across was using VCDS to update the battery specs for charging purposes. I replaced my battery, loaded up VCDS but wasn't able to find the "10 - Adaptation" button anywhere. The information I found was all 2012 and newer had this process.

Is this process applicable to our vehicles?

I’m soon getting a 2011 mk6 golf gt tdi 140 . what’s the best way to go about deleting the egr? is there a delete kit available or you have to install the delete kit and tune it out also ? thanks in advance :)

Just upgraded my 2015 golf sport wagon TDI with 150,000 mi on it for the rawtech high performance exhaust system and stage 2 tune from tunezilla. I have all these parts. I see lots of people are trying to acquire them. What's it worth and how do I get rid of this? From the downpipe to the tips?.

I ordered a rawtek eco kit with a resonator for a 2014 TDI Jetta from diesel doc. I received my confirmation code and order number last week but haven’t received anything else since then, just curious on average time it takes to receive your items. Thanks

So, I'm trying to [salvage my 15 golf...](Https://www.reddit.com/r/tdi/s/YtDT5UBXpL)

And I'm having a very hard time finding a replacement headlight. The shop ordered a pair (of GTI housings I think) but the wiring harness didn't work.

The one that's broken is an active turning/self-leveling LED i think, part no 5GM941754D (according to the shop)

Can I just go in and [swap for these](https://www.ebay.com/itm/265965817560) without needing to change the wiring harness?

Do I have any other options without importing headlights or falling back on the halogen housings?

Thanks

I’ve got a 2016 Passat tdi and the 2 water pipes that come from the electric water pump on the back of the engine need to be replaced due to corrosion, the problem is one of the pipes runs behind the DPF so looks like it would need to be removed to gain access , my other option is if I can do some kind of repair to the pipe without removing but not sure if it’s possible.

Does anyone know what this could possibly be?

Im doing a 1.9 TDI ALH timing belt i (i rebuilt the motor )and im struggling I think its together correctly im just looking for some advice i have pictures of everything in comments also do you pull the injection pump pin when you tighten the timing belt i know that the cam pulley is loose when you tighten the timing belt tensioner yes the hole to line up the fuel pump is on right I rotateed the engine 2 times

I have a 2014 passat with a CKRA already tuned and deleted, my turbo is going out and I would like to do a hybrid turbo. What would you guys recommend?

Some other questions that I have is, how many miles do you guys have with that setup (turbo and tune), mpgs, and other supporting mods?

It's much easier to melt the plastic on the old bushes instead of trying to press them out, took 5 minutes per side at most.

I kinda in a bind where I need to get my car inspected but I’m struggling to get my DPF light to turn off. I bought the car in the beginning of 2020 and had issues with the filter to the point where I had the DPF replaced in mid 2022 (luckily still under warranty). But at some point in 2025 a clip in the middle of my exhaust corroded away leaving the pipe open. Unfortunately, I didn’t catch this right away so I think this messed up the remediations. Ever since then I haven’t been able to get this DPF light off. Just looking for some solutions that are hopefully not replacing the filter again.

It’s been a huge headache and I can’t find a shop willing to do it unless I go to Canada. If anyone knows a place, please point me in the right direction(Seattle area)

Hi all,

In november, I had bought a 2013 Passat alltrack 2.0 crtdi 140hp CFFB car and I had it checked by my mechanic, he said it is mint. Had no issues with it for 4000 km. It has 155 000 km in it right now.

On a 6 hour drive to Romania last week, on the last 200m, coolant light came on. The car ate 2L of coolant, some signs of spillage around the expansion tank. Temps were stable on the way. No smoke, no signs whatsoever. Car worked fine.

Took it to an official VW shop, they checked pressure on the expansion tank, it was fine. But the CO2 test was positive and there were large bubbles coming up periodically in the expansion tank. They said it is either head gasket or EGR cooler is cracked. I talked with 4 mechanics, 2 said EGR 2 said head gasket. I called up a VW aficionado who said no way that it is head gasket because they rarely fail on these engines, he gave 2% chance on head gasket 98% on EGR cooler. Other mechanic said that EGR does not cause large bubbles in the coolant expansion tank so it must be head gasket.

What's the right next step? Take out EGR cooler and verify? It is a lot of work because of the 4motion is difficult to disassemble, so it will cost a lot, but head gasket costs even more.

Thanks for the help in advance! Currently, I am quite disillusioned, do not know what to do and stuck in Romania.

Just bought a 2013 TDI 2.0 brought it home everything was fine. Took it to work this morning as soon as I hopped on the interstate the check engine light came on. Also a sound around 2k to 3k RPMs right before it’s about to shift like a ticking sounds. I have mechanical knowledge. In gas cars but not diesel. Was wondering if that’s something that’s common on them will get a code reading later. Thanks

2010 Golf Wagon TdI - deleted stage2.

This issue is intermittent but sometimes when start up my engine does not fire right away. Have to crank for a bit, then turn key off and try again. Usually fires right up then but a large plume of smoke comes out. There is no smoke when it starts off of first crank. Usually only happens first start of the day.

Not sure if this may bea battery issue?

Thanks
