No, I drilled 1/16" holes in the plastic ribs on the IC housing, and ran lock wire through. You need lock-wire pliers to do it properly but you could probably twist the wire with regular pliers in a pinch. Mine is rock solid and not going anywhere. If for any reason I ever need to remove the sensor, I'll just cut the wire.

I'll try to take a picture tonight if it's of any help?

I had to replace the IC last year and being the dummy that I am decided to swap my original MAP sensor into my newly acquired IC. One touch with the screwdriver and the screw heads snapped off with little to no effort.
Wow, you feel my frustration, then!

Yes a photo would help greatly. I've not yet gotten around to tearing the bumper off, but if you're saying I might be able to get away with not ripping apart TWO cars I would really appreciate the help! Thanks!

New fuel filter with amsoil deisel purge
New oil amsoil 5w-40
New manual transmission fluid
-drained LiquiMoly 75w-90 (hated it, lesson learned)
-replaced with Pennzoil synchromesh (love it, slick as alligator spit)

Cleaned magnet drain plugs. Found shavings, not good. But happy I had the magnet plugs oil and mtf, thanks to ecs.

Found vw g070 manual transmission fluid on sale for around $11. Not bad price but I already installed pennzoil

Car drives so good now. I'm enjoying it all over again.

Actually yesterday:

Removed EGR cooler, installed block off plates, etc.
Installed spare set of headlights (existing glass lens took a hit).
Lost 5 pounds in the 104 F heat of the day.

Last night managed to get the intercoolers out of the '01 parts car and '03 DD. '01 was fine, just some impacted fins from gravel, '03s was literally clogged with grease on the front. Not sure if from misapplied Krown or a long time leak.

Also drilled & tapped two snapped bolts that hold the bumper on.

I'm planning on upgrading to VR6 front brakes on my 99.5 Golf. I got a good deal on some clean west coast VR6 knuckles so I spent a few nights this week replacing the wheel bearings and ball joints.



It was nice for once to work on a car project while the car is still drivable and not be in a race against time to get it fixed.

Next stop: Swap the TDI knuckles for the new ones and install the calipers, carriers, rotors and pads.

That's cool! Good luck. I would love to do this on my 99.5' also.
Would the vr6 Knuckle and brakes give you better bite? Are they bigger?

The rotors are a little bigger (288mm vs 280mm) and thicker and the brake pads have more contact area with the rotors. There are a few VR6 brake upgrade threads on TDIClub. The following post talks about some of the advantages:

I'm partly doing this for the better braking but also because most of what I'm replacing is so old and rusty on my almost 18-year-old car.

Over the last few days and next few days... Replaced alternator with a 120 amp Valeo unit from IDPARTS, refilled coolant, swapped out coolant overflow bottle, drained gearbox oil and refilled with Syncromesh, removed all inner fenders for cleaning, and spray painted backside of fenders. Might do pads and rotors all around if I have time also. It's tough to finding time for vehicle maintenance working 60 hours a week.

Brakes all 4 corners. Pads and rotors. Existing ones were super shot, one pad down to the lining, slides all frozen. What a mess...

Had/having the windows tinted on both mine and my wife's TDI's. Going with 30% LLumar ceramic on all windows except windshield. Mine was done today, love it so far!!

Over the last few days, replaced everything between the turbo and the EGR valve, changed engine mounts L and R with new Class 10.9 bolts, replaced A/C compressor, replaced idler pulley (bad bearings, guess the alternator is good after all!!!), and managed to snap one of the dogbone mount bolts... then snapped off a bolt extractor inside that...

Will be replacing the subframe. BAH

Been busy the past week and a half. Ran into lots of little issues along the way, thankfully my landlords let me borrow one of their TDIs for emergency parts runs.

G60 single mass flywheel and clutch
Rebuilt outer CV joints, replaced inners as the inner race/spiders were scored
Power Plus 520 nozzles and injectors StageIII with modified pilot injection (Drive by Wire hotswap)
NewSouth EGT and boost gauges in the dual coulumn pod (think I'll make something better later)
Turbo oil feed and drain lines (snapped the feedline trying to loosen the fitting)
IdParts 2.5" downpipe with cat
Eurosport 2.5" catback exhaust (if you are considering this, be aware that the inlet is 2")
Fremax high carbon rotors with IdParts ceramic pads (had to repair a stripped front caliper slide pin thread)
Cleaned the intake
Installed rear towing springs (I'll be dragging a 1978 Serro Scotty travel trailer around the country for the next month)
Brake fluid flush
New G70 gear oil in the transmission
DieselGeek Sigma5 short shifter
DieselGeek Panzer skid
CCV breather tube
New vacuum lines
Oil change, engine and cabin air filter, diesel filter

Probably forgetting a couple of the smaller things. Felt good to be working on the car again. Spent the last four years in school for engineering and had no time (or money) for anything other than basic maintenance.

So many little things needed fixing along the way, drug the project out longer than it needed to go. The mechanic at the shop I bought the car from damaged the threads on one of the caliper slide pins, which stripped out the threads in the knuckle. I was contemplating replacing the knuckle at first, but a helicoil fixed it since the pin pretty much only sees shearing forces.
Lost half a day looking for the stupid stainless ferrule for the EGT pyrometer fitting. Nobody was home so I couldn't even go looking for a replacement.
I thought I was going to get away with just replacing CV boots since they were just stiff from age, but there was galling at the center of the inner races, so I had to replace the inner joints.

Now I just need to replace the front driver's side wheel bearing, lower ball joints, get some new tires, an alignment, and get the injection quantity settled once VCDS finishes updating so I can get on the road. I'll have to wait a week or two before I can get the car tuned (Malone stage III custom with modified EGR and cold idle) since Mark is on vacation.

Driving the car with the nozzles and exhaust (well, downpipe. Waiting for a coupling so I can cut the 2" section off the exhaust to connect it to the 2.5" downpipe) even without any adjustments is amazing. The power is there right off idle. I haven't really gotten on it yet since the clutch needs to break in. With just the downpipe, hearing the turbo spool up and down is pretty awesome, although the volume will get old shortly.

The pedal pressure on the new clutch is nothing. It almost feels like I messed something up flushing the brake/clutch fluid, but the pressure is amazingly light. Will be nice in traffic. Glad to have more than 3/4" of pedal throw once the clutch starts engaging. The old clutch was pretty worn.

Still amazed at how many single use bolts there are on this car.

Well, at first I thought our TDI was overheating but turns out it was just slightly low on coolant. I was told the warning light came on "a few times" but didn't get the whole story from my grandmother who is the usual driver. I derped a bit and overlooked the obvious cause, but I also ended up finding out the primary cooling fan was broken. Went for a test drive and it wasn't overheating (88-90C on the highway, ~93C stopped at a light, 96C parked & revving the engine). Bench tested both fans direct to battery for confirmation, motors just dead.

Seems like these TDI's don't really need much cooling, but for piece of mind and maybe help the AC out a bit I've ordered a replacement fan.

TDIs don't need the fans often, but if they don't run your A/C won't work.

I've run 30 minute track sessions where I'm shifting at 5500 RPM, EGTs at 1500 on every straight, track surface temp around 100F, and when I come into the pits the fans aren't running. They start running at 97c, and even with that kind of abuse the car won't always get that hot. After I blew a head gasket on my Golf I got super vigilant about fans running, used to plug in VCDS to check coolant temp as soon as I got into the pits. And the car simply didn't get hot.

After 3+ weeks of 104 F and 70% humidity, my A/C is very important here in south Texas. Matter of fact, I doubt anyone here would buy a used car if the A/C didn't work! (we need the fans working)

I know its no Texas but we've been having record heat waves up here in New England. High 90s for weeks, but finally its starting to drop back to the 80s.

Yea, the smaller fan still works fine. I did bench test it also to make sure both high and low speed worked, and they do. Didn't notice any performance issues with the AC with just the one fan, but we'll see if it works better or not with the second fan running.

I lived in CT for almost 40 years and remember those hot spells once in a while. Our house had no A/C so we used fans. I do miss the 4 seasons as all we have here is summer and fall.

Are there aftermarket fan upgrade kits using Spal fans? I had problems in stop-n-go traffic with my Miata's OEM fans; installing an aftermarket fan upgrade kit fixed that. The kit pulls 4540 m3/h at 0 pressure. The only drawback is that the fans are loud.

No need to upgrade fans on a TDI. As posted above, the cooling demand for the diesel is very low. I agree on the A/C however. The A/C in my Passat isn't working and as a result it's been driven very little this Summer.

Took off the gti badge from my car finally. I also replaced my drivers side window regulator. I accidentally ordered the wrong part from ID parts (regulator for the four door model golf) so I had to wait a week to get the right one from ECS.
Not complaining about ID parts though I should have known they may have been different.

I also made progress in fixing my a/c. I was finally able to jump my ac clutch. It turns out that I must have not tightened the nut far enough because the clutch would engage if I pushed it in and jumped a line from the battery. I tightened it up and it now engages without pressure but needs a jump.

Now my next step will be completing the circuit test from Dan.
I have replaced my a/c high pressure switch, whole a/c clutch assembly, and had the system charged with 750g of freon.
The a/c blows cold so now I just have to figure out why the clutch isn't engaging by its self.

Resealed the oil pan to see if that's the cause of the oil leak and not the rear main seal.

Added helper springs to the rear calipers to assist with the parking brake return issue.

Replaced the a/c compressor, expansion valve(pain in the rear), and drier. Then vacuumed and recharged the system. Nice to have cool air again!
