I started using an online parts shop in the Czech Republic called oemvwshop.com over a year ago and they have been great. I have found stuff from them that I couldn't find anywhere domestically, including my local dealer. Even though they're in Europe, most shipping costs are usually pretty reasonable for normal size/weight items, around $35 for DHL Express. The total cost for all of the brake parts was $2000 not including the rotors and brake lines. I comparison shopped, and this saved me $500-600 dollars compared to a shop like ECS or the dealer. I got OEM rotors from ECS for another $500 along with the special spacer you need to attach the rear carriers ($25.) I made this decision because the shipping costs for the rotors from OEMVWShop due to their weight would have canceled out any savings. You could probably find 3rd party rotors for less. Darkside made me a custom set of brake lines for $65 (the R32 connectors for the front calipers are different.) I already had 337/20th Anniversary brakes, so I didn't need the rear rotors or splash shields.

This is the whole list of parts:

1J0615123E - Front Left Caliper
1J0615124E - Front Right Caliper
1J0615125B - Front Carrier Left
1J0615126B - Front Carrier Right
1J0615423F - Rear Caliper Left
1J0615424G - Rear Caliper Right
1J0615425F - Rear Carriers x 2
8N0615311C - Front Splash Shield Left
8N0615312C - Front Splash Shield Right
1J0615301AA - Front Left Rotor
1J0615302A - Front Right Rotor
8D0615269 - Front Retaining Spring x 2
Darkside Brake Lines
ECS Rear Carrier Spacer

So $2,600 about for a big brake kit?
That's using the site he did and getting the GREAT deals on the front calipers and carriers. Which look to be a sale price, not an every day price.

Keep in mind the R32 front set-up requires higher priced front rotors as an ongoing maintenance.
The MKIV platform offers a few different front brake set ups 280mm, 288mm, 312mm & 334mm. (the Audi TT MK1 shares the last 2).
The first 3 use the same caliper, just different carriers (the 280 carrier being fixed to the knuckle) and the 334 (R32/TT 3.2) set up uses a 2 piston caliper. Blue as shown in the pics above.

And the 334 set up only fits under a few 17" wheels, so many use 18" wheels.


Rears fall into 2 groups
232x9 solid
256x22 vented
There's a different carrier for the 256x22 rear caliper when used on an AWD car, and as mentioned above, spacers can be used to allow the AWD caliper/carrier set-up to be used on a FWD car.


There are TONS of brake options for the MKIV (& TT MK1) platform, the question is what's your priority? How much do you want to spend?

Let me preface this by saying, we're going to talk about bigger brakes. I don't want to start a big debate/discussion about better brakes, this is just about bigger brakes :).

To increase the size of the front brakes the first thing you would have to do is replace your front "knuckle". The MKIV TDI and 2.0 (gasser) comes with a 280mm front set-up with the caliper carrier fixed to the knuckle. Once you do that, you're open to most all the front options I mentioned above, plus you also open up to a few aftermarket and other OEM calipers with adapters. But these still require the knuckle that supports the removable carrier.

Some like to swap the knuckles and go for the 288mm rotor/caliper & carrier set-up. This is commonly referred to as the 1.8t/VR6 set-up, as it came stock on most 1.8t & VR6 MKIV's. Some variations of the 1.8t (& the TT MK1) came with a 312MM front set-up, which was the same knuckle (different for TT) and caliper, just a "taller" carrier. This is probably the 2nd most common (the 334mm/R32 set-up benmarks went with is fairly rare, due to price and used market & future rotor prices).

Another option is the 1.8t/VR6 knuckle, the 312mm rotor, adapters and Brembo 4 piston calipers (fronts from the Porsche Boxster non-S).

That doesn't cover all the options, but touches a few of the more common front bigger brake options using mainly OEM parts. There's a HUGE thread over on VWVortex that goes into detail on many more options.

For the rear, it's typically the "vented rotor" caliper and carrier, that support as the 256x22 rotor. Some of the 1.8t MKIV (2oth AE, 337, later GLI, etc.) used these, so they bolt right up to the MKIV TDI. If you get the vented rear caliper with an AWD carrier, ECS makes a set of spacers that run about $25-30 to offset the caliper/carrier combination enough to allow them to be used on FWD car.

There are also some more aggressive options (280 or 288, using the MKIV smaller front rotors, but need a daters and then you get into e-bake cable stuff, blah, blah, blah) for the rear too, but this is the most common "bigger" rear.

I had rounded up soooooooooooooooo many different pieces over the years, even 18z's at one point, but now have a TT with the same set-up benmarks showed (expect not blue & no rear bracket/spacer) and just don't see me doing anything except possibly going for a lighter 2 piece rotor set-up ... once I use up all my spare parts.


Hope that helps.

Yeah it was. He was just low on power. He's running 230 nozzles and a Vnt17.

Our 2002 wagon has had intermittent limp mode for a while with the charge negative
deviation code. I ran the operational N75 test and got zero vacuum after the N75.
The vacuum pump pulls down to 25" Hg so that's not it.
We'll see if a new N75 does the trick when it shows up next week, courtesy of IDParts.

Spare n75 and a 109 relay are always nice to keep in the trunk ;)

Will the 1J0906381A 109 relay work in a PD TDI? IDParts says: "Relay 109 is the main power supply relay for A3/B4, and A4 TDIs with the ALH engine" while mine is BEW.

If not, what is the correct VW part number for the PD 109 relay?

As far as I know, they use the same relay. The gray one is the updated part and last a long time compared to the bulkier black 109 relay.

Thanks. The picture on the IDParts site seems to show the black version so I sent them an email asking if they have the gray one.

Black versus gray no longer matters. We do our best to get ones from Euro suppliers, but they are all the same design now.

Just rolled over 350k km, passed some adventure big rig camping truck thingie and as I pulled by there was this crazy loud shuddering sound. Thought my flywheel exploded but turns out that truck had his exhaust pointed right at my passenger windows since it was lifted to the moon. (Think Dakar rally support truck) yikes.

On another note I kind of ordered a new car, 2020 Subaru Legacy Limited GT (XT for you Americans).
It's time for more amenities and AWD. Will still keep the Jetta and possibly do a 2260 of some sorts in the future, it'll be my really fun car.

Finally ordered a new fuel cap because the lanyard on my old one broke. Also finally took the time to figure out how to hang the cap properly on the fuel door. Simple yet satisfying. Shouldn't be breaking any more lanyards anymore:D

Does the 2002 Golf have a bracket on the fuel door?

I was finally able to get to replacing my front driver lock module. Removal went well until I realized that the tab that runs along the top edge of the door card snapped off! Ugh! This was a JY find that repacked my original one which was super flappy after the same tab broke off. Now I have the door card sitting in my garage clamped up waiting for the epoxy to cure and re-secure the broken tab. I’m hoping it takes and the lock module replacement cures my alarm going off at random hours of the day AND night!

The fuel cap should have a couple notches, and that should allow the cap to sit on the door.
OK, then it is like my Jetta. I didn't understand the comment about figuring how to hang the cap as mine just clips on the door using 2 of the notches with the lanyard cap connection 180 degrees from the door. Any other position of the lanyard connection puts strain on the lanyard and its body attachment point.

Correct. I had never even noticed the notches prior, and had just let it hang from the lanyard while fueling. Until 1 day it broke. Then I put it on the pump after that while filling.
When I looked at my new one I purchased, I saw the notches. Both old and new caps had them, just never even thought to look on the cap itself. My Cummins cap hangs by a spot welded bracket on the inside of the door. I had the truck before the car, and the TDI is the first car I've owned. Just cool things I guess I notice along the way.

I put 4 hankook kinergy h735 tires on my car (upgraded size from 205 70 r 15 ecopias to 205 75 r15 ..
I'm hoping for better fuel mileage because of the overall larger tires...

I only drove the car twice so far after having the tires put on an it seems quieter and a little less peppy but I guess that's understandable because of the higher effective gearing.

unfortunately I haven't driven anymore because my starter went out and I'm waiting for a new bosch replacement to come in tomorrow...

Oh I forgot, I had tire pressure monitoring system installed along with the new tires ....

I wanna drive bad to see about mileage before I install the 3" turbo back exhaust and brm intake manifold .

I feel like a kid just before xnas!

Golf: Replaced the AC compressor, condenser and receiver drier. The compressor was no longer compressing. (Yeah, it might have been just the RCV but the compressor was 21+ years old and super corroded.) Also replaced the power steering pump (started leaking underneath) and the high pressure power steering line (very corroded and didn't look like it was going to last much longer).

To anyone opening up the AC: You're going to need to replace the receiver drier and if your car is old and corroded like mine, it's going to be very hard to get the top bolt off that connects the receiver drier to the condenser. Do yourself a favor and just pull off the lock carrier as shown in this video: https://www.youtube.com/watch?v=HkiwMq02Dhc
It's not that hard and it'll give you a lot better access to that top bolt.

It's a bit confusing because they do not have "109" on them. Just "Mahle" and a part number.

But I've got three TDIs and all three have a spare 109 in the glove box. Just cheap insurance.
