Some people say the the rust in the lower corners of the rear window is the result of a weld breaking inside the hatch at those corners. You may want to look there and repair if necessary while it's apart. Otherwise moisture will get in again right away.
Drill a tiny hole and squirt it a couple ounces of Krown

2001 Beetle GLS TDI (BIODSL). 01 original Glow Bug TDI (sold)
Lost a/c the other day with windows fogging up pretty bad during heavy rains last week .
Finally got around to looking at it , a/c compressor runs fine but no fans , fuse is good.
Tested both fans low speed and they are non existent…..ohms check out is infinity….. looks like I’m gonna need two new fans.

Anyone recommend a good place for moderate priced fans?
Not new, but when my fan went bad I pulled one out of a gasser since they generally have lower miles. Not a common in need part so they are generally pretty cheap. I think I paid about 10$. Only takes about 45min to install the passenger side fan in the bug and 5min of that is putting it on stands and removing the skidplate. W/J/G should be easier then that.

wasn't my tdi, but this is what i use for easy no-weld, no-fuss, no-leak boost tap:



can be found super cheap on amazon/aliexpress. you can use these on alumumum/stainless pipes too - i just use a large bolt/washer/nut after i drill the hole to clamp it down to make a flatter sealing surface. just needs to be placed close enough to the end of the pipe you can use pliers to get it in there . in this case i used some long reach pliers.

take out the schrader valve, use a short piece of larger vac line + reducer to the small boost line to your gauge. you can plug it up by putting the schraeder valve back in. also convenient as a place to put air in the system for pressure testing :)

Neat!! Never thought of that, but I've used one of those to replace the nipple on the bottom of my garden tractor's gas tank 😄

yeah, they work great, i love 'em. for us common folk who don't have a welder. although, even if i could weld, i think i'd still choose this method.. buy a pack of them super cheap. i've put these in a few mk4's and others. and no leaks. i cringe when seeing those plastic pipes drilled and tapped with like barely 3 threads in plastic.. which will often leak even if with teflon tape. just not enough meat.

My first 2003 TDI got a used 5 speed after the original 5 gear failed. Two years ago it had stripped the teeth off of the shaft. I welded it back on and it worked for 30k, just shy of 2 years. I put a used one in from a silver Golf I picked up at the auction a few years ago. It belonged to a member here I'm guessing from the tdi.com decal on the window. The car looked like it was launched. Both hubs were snapped off and 3 of the four struts were bent. I hope no one was hurt.

Man you need a welder, even if it's just a little 110 flux rig. I bought my brother in law's Hobart 210 and it's saved me so much hassle so many times. That and I just love fabricating stuff. Couldn't use it to fix the gas tank though as it's a plastic tank 😄

i know i do, and i would love it. i've contemplated getting a basic harbor freight welder, but i'm literally up to my eyeballs in wayyyyy too much stuff going on. i can't afford a whole other project/setup/learning-experience lol. i don't even have a shop. my basement is a half-finished total gut/renovation- been languishing for years unable to get the time to work on it, and now full of carp parts/tools, lumber/wood, building supplies, contractor tools, random crap... it was supposed to be a finished living space 5+ yrs ago. 😩 but not having welder keeps my creativity level up :p generally, i'm able to do all i need to do without it - aside from a couple things - like custom exhaust of course or weld-on map sensor flange. for future planned pipe-dream projects welding capability will be necessary :)

I have one of those Harbor Freight welders and can confirm they suck!

I am a little spoiled having access, at points in my life, to much better equipment and have found some of those cheap welders actually make it harder to weld without a lot of practice. For that same class (size/rating/etc) a cheap unit will make you walk away and say its not for you vs a better quality unit getting you hooked.

You don't need to drop massive amounts on name brand, but it will make a difference spending a few extra bucks. I think you can even get a decent Hobart at Harbor Freight or Northern Tool vs their store brand.

I may swap the backs, too. But not sure how hard that is.
Nice score with the Recaro seats!! Even the driver's seat thigh bolster looks decent, but good idea swapping them.
Rear seat bottoms swaps are measured in seconds, not minutes (it's that easy) of course; the backs are a little more involved, but not by much.

No one ever sits in the back, really.

I meant the backrests on the front seats. To keep controls on the correct (outside) side, it's a lot of work.

So I just swapped the bottom cushions side to side, and discovered the bracket for the fore/aft adjuster lever is broke. Seller refunded me $50 for that, which is ok.

I might grind the bracket off my old front seat and weld that to the recaro. But then I can't sell my old set, really. I'll figure it out in the summer when I have more time to dick around with it.

installed the seats when I got home. Very comfy

The wagon runs!! First time fired up in months, thanks to the postman dropping my elbow this morning !
It means i didnt screw anything up installing the 1856v nd pd150.
Thats incredible, but also i was unsure what the cpu would do without the tune to delete my 'smart' vnt actuator! I took it for a rip today (minus the back window) and it felt awesome to have boost again. Solved my injector 1 misfire issue as well! It purs instead of bouncing around while idling.
Im stoked to have it running again and kinda wish i never started down the Rust-eration path.
I stopped by the wreckers today on my drive and found a mint gasser 2.0 wagon that im thinking ill buy for the body parts... rust free, too bad its not an alh manual

Are you referring to the post number or how close to your member number ???
I didn't know there was that many users over the years. 😀
Neither, the number of pages in this thread, 420. :D


But now I'm curious, where are you seeing a member number?

Just finished my morning commute in the Recaros for the first time. Fan-freaking-tastic. The "normal" VW sport seats are a step up from the base ones, but the GLi seats are lightyears ahead of them both.

"I smoked , but I never inhaled"
~ Bill Clinton :ROFLMAO:
Speaking of smoking, I noticed after my first test drive with the untuned PD 150 and 1856... that the engine bay was like really really hot... this got me thinking maybe my rerouting of the coolant lines might not be working super efficiently or something.
I did step on it a couple of times because I was excited to have boost pressure... Anyone got any ideas?.. other than taking it easy until its tuned for that bigger turbo.

After my VCDS, I didn't get a no boost code! But I did get some others...
00300 - Transmission Fluid Temp. Sensor (G93)
27-10 - Implausible Signal - Intermittent
It's in tandem with brake light switch and triptonic switch.
I replaced the brake light switch already, so I'm hoping that clearing that code will work.
But maybe its a solenoid or fuse or something.

Ideas?

Probably the 420 factor
