2000 TDI Jetta, just getting verified and wrapping my head around all this

[Wrenchly]

I'm still getting the initial setup finalized, but here goes with doing things backwards! A full auto-scan:

End----(Elapsed Time: 05:25, VBatt start/end: 11.9V/11.9V. VIgn 11.8V)-----

The primary reason I bought in to this was to get some old keys deleted from the car, but I guess that's not really what I should be worried about! And it seems I need a PIN to deal with that, but I'm PIN-less at this point so I guess that can wait for another day

The car has a number of things that need work, and I had only known about a couple items the scan is listing. I knew about the turbo boost going negative, and the glow plug heater circuit. All the rest is new territory for me

The combo coolant temp sensor seems to have a bad connection at the harness connector, still haven't sprayed some contact cleaner in that. The dash gauge stops working at times, but after unplugging & plugging it back in, was 'fixed' for a while

Every now & then, the brakes make a really bad grinding noise and the pedal feels like a bucket of gravel went through the caliper

And my most favorite problem, the turbo never gets past 2.8lbs most days. But on random cold starts, will jump to 10 lbs in 2nd & 3rd. I do wish it would always hit 10 lbs everytime I floor the car. I'm thinking there's probably a ton of gunk in the works that needs to get cleaned out the hard way

However, if anybody knows what it takes to shut down the radio for the key fob remotes, I'd like to look into that at some point. Thanks!

For start your car is 2000 not 99.5.

-At 300k Most likely you need turbo. If this car was driven like old lady does it , then Turbo on those cars get lot of carbon at exhaust side and actuator start getting stuck at some points, if this keep going for long time it will damage rod inside turbo and there is no way to fix it , 99% this is your problem.
-Brake switch is know problem on Mk4 cars , So I suggest change it, they are relatively cheap , maybe $20.
-16764 - Glow Plug/Heater (Q6) Circuit----- Either Harness is bad or glow plugs , Look at your harness and if you see braking in peaces , need harness.
- Coolant Temperature Sensor fault in Cluster , also know problem on those cars , Change sensor and make sure you buy original form VW Dealer, OEM or Aftermarket are junk.
-For ABS, check sensor .

Well there you go, first basic mistake! Had to go & look at the registration, but you got that right, it's a 2000. Might just write that on the dash where I can see it, for every time I stop in at the parts store. Funny thing is there's this tag in the binder that has the owners manual, says in green letters 'MY 2000'

I see a range of years on that scan log, but nothing that specifically states it's a 2000. How can you tell from that?

Previous owner was an old lady who drove drunk a lot. Lots of interior damage, passenger mirror broken off & missing, right rear door badly dented but still opens & closes. Few other little things like the thermostat was missing. I had thought the temp gauge was broken the first month until I realized the coolant wasn't really hot enough. I think the car was driven like that for a long while. It made more power after I put in a thermostat. I'm expecting that turbo is more than just clogged a bit

The dash gauge worked after fiddling with the connector. I had unplugged it to see if there was power to each glowplug. I guess it couldn't hurt to just change that out, but it also couldn't hurt to spray it down with some contact cleaner 1st. Would it work to just get a sensor from the outfit I bought the Hex-V2? They looked pretty serious for everything else they were selling. That was Cascade German in Gresham Oregon

I checked the resistance on the glowplugs, and they're all in spec and pretty close to exactly the same value

The plastic insulation on the glowplug harness fell apart when I checked for power, I actually had forgotten to look for one of those. It's connected with aftermarket inline crimps, so I think it's been changed out once already. I think that would be the 1st thing to try

Looking at the wheel speed sensor is on my mind, but so is this freezing cold rain out in the muddy yard I'm working in...

Yup! I've fixed the thread title.

From Part numbers of modules .

 

[Wrenchly]

From Part numbers of modules .

Ok, so the modules in each model year get unique part numbers? I would have expected something like that to only change between the generations

How do you use the part number to find a year? I don't see anything in those that would indicate the number '2000', so the obvious is out

 

[PetrolDave]

The suffix of part numbers changes too - indicating newer versions either for a model update (including but not restricted to model year changes) or an update for a new model.

The suffix is like a version number? There should be a list of all known part numbers somewhere

 

[PetrolDave]

Yes like, but not only, a version number. And, importantly, a later version is in many cases NOT a suitable replacement...

Lists of version numbers seems to be a closely guarded VAG secret - the best available are lists of superceded parts and their suggested replacements.

Yes, it's confusing but VAG seem to like it that way

Ok, well I think a list of superceded/replacement parts is pretty much what I was thinking of - being that would be what we would know for sure

Wouldn't a 'suggested replacement' be a case where sometimes the later version isn't suitable? I'm assuming that these part numbers only concern logic control modules installed on my car, which I would assume can be a bit finicky when hardware isn't exactly the same as what the firmware expects to see, right?

There was a huge transition between MY 1999 and MY 2000. These cars got internal CAN buses during that transition, and the instrument cluster is a dead give-away. 1J0-920-... is a CAN bus instrument cluster found only on MY2000 and newer, whereas 1999 and earlier had 1J0-919-... clusters.

There are other clues as well. The fact that your have "Address 19: CAN Gateway". MY 1999 and earlier simply didn't have that. Plus the fact that your cluster shows IMMO data. 1999 and earlier NAR cars didn't have that either.

You could have avoided the possible confusion by posting the UNEDITED Auto-Scan (i.e. not removing the VIN ).

In many fault conditions the VIN can be important, which is why we always ask for an UNEDITED Auto-Scan.

I didn't do any editing to the saved log file, I had assumed the VIN was not there because the software had been updated to no longer include it. I see enough tutorial videos on how to use software, in which the current version is changed in various ways without the video itself having been updated, I just thought it was that sort of thing

I'll do another auto-scan and see if it looks any different before exporting to a text file

Not in this case. MY 2000 and 2001 Mk.4 cars used Immo-2 and did not know their own VIN, hence VCDS has no way of knowing it or including it in the scan.

[Uwe]

Without careful, detailed research of the part numbers, it could indeed be a 2001, but not a 2002 or newer because those use Immo-3 and do know their own VIN. They would also show Immo data under the ECU, which yours does not.

Well that seems to settle that! All part of being very familiar with VCDS I would think

Maybe the Ross-Tech software could include a placeholder to show that the VIN is missing due to this, and not edited out?

I did not know that, I had *assumed* that knowing the VIN was mandatory for OBD vehicles - good to know otherwise.
