Check the coding in the 19-CAN gateway. I'm assuming your car is not equipped with the telephone. My car doesn't have that module so I'm not familiar with coding it. Play around in VCDS and see if it becomes obvious.

Also check coding of the 01-engine module.

I don't see any SAIP codes in the engine controller. Are you sure it's not functioning?

Now that you have all the code numbers written down, clear all the modules and see which codes come back.

 

Good call on clearing the codes. I should have done that before posting this autoscan. I will clear the codes tomorrow and check which ones come back.

I looked up the ECU coding a few weeks back and believe the ECU is coded for a 6 speed. This car is automatic. I wonder why that is, and how can I code it back?

Pretty sure the SAIP is not working. I don't hear the tell tale "vacuum cleaner" sound on start up. I have been researching how to test the relay, check fuse, test pump motor, etc. Now that I have a registered version of VCDS-Lite, couldn't I just use that to check individual components?

Regarding the 19-Can gateway, you assume correctly, there is no phone. A quick search pulled up this thread:
http://www.passatworld.com/forums/68-b5-garage/356226-can-gateway-coding-problem.html

I'll play around with VCDS tomorrow, after the axle and new brake pads.

 

If the SAIP isn't throwing any codes, don't worry about it for now. When that system wants some attention, it'll let you know. I do remember running a SAIP test in VCDS but I forget how. The test cycled the system on/off with the engine not running so the system was easier to hear and test.

 

Ok, So I cleared the codes, packed up the wife and pooch, and drove 1400 miles from Vermont to Florida. The CEL came on at 227 miles. When I got here I pulled the codes and this is what returned:

While here in Tampa, I'm going do PCV overhaul, clean the injectors, install an oil pressure guage sending unit, replace the vacuum lines, etc.

Any thoughts?

 

I think you should check and correct the coding of the modules reporting themselves as coded incorrectly. With those out of the way (and any secondary's they spawn), it'll be easier to interpret what's left.

Those low voltage codes are typically something you see after a battery disconnect or removing fuses. Did you do either of those?

The "engine speed sensor no signal" can keep the car from starting or running. Unplugging connectors can log codes like that. Was this one triggered by an actual fault or caused by harness disconnect?

 

Thanks Steve. Got it, I will check and correct the coding on the modules, especially the engine control module.

I did not disconnect the battery or remove any fuses, however, the battery has been weak and required a jump twice in the past week, so I will need to replace the battery.

The car has been hard to start occasionally. It cranks for about 3-5 seconds before it actually starts. This does not happen all the time, but more often than not. I have not unplugged any connectors other than the O2 sensor (I replaced the precat sensor), but other than that, nothing. I also did not touch anything before the hard starting problem started (3-4 months ago?). So my guess is that this is an actual code.

Thanks for your input Steve, much appreciated. I will correct the coding, do the work I said I will do, clear the codes and repost anything that comes up. Merry Christmas!

 

Question regarding the coding of the ECM:

The coding that appears after the VCDS Scan is "0016051." According to the Bentley, some model years display a 7 digit code instead of 5, so disregarding the first two digits leaves me with 16051.

Bently page Z-27 gives me the coding variations:

"16" = Emission Standard ULEV (Ultra Low Emissions Vehicle)
"0" = Front Wheel Drive WITHOUT Anti Slip Regulation (ASR)
"5" = 5-speed auto with Tiptronic
"1" = B Class (B5 Passat)

Soooooo . . .

The ASR light in my Passat is illuminated, leading me to believe that my Passat came equipped with ASR. So, from that, I believe that the correct coding should be "0016551." The fifth digit changing from "0" (without ASR) to "5" (FWD w/ ASR).

Is that correct?

 

...I believe that the correct coding should be "0016551." The fifth digit changing from "0" (without ASR) to "5" (FWD w/ ASR).

I agree, it looks like that should be the correct coding for your car.

Your ABS module is coded 00022. That's for 1.8t, ASR, CAN-BUS, Manual Transmission.
You want to re-code it to 00021. That's for 1.8t, ASR, CAB-BUS, Automatic Transmission.

Do some research on your trans module and CAN gateway coding to see if those are correct or not.

 

hey quick question, how much did you pay for your raxles? i need to get better axles and was recomended to talk to marty at raxles.

 

I paid $199 (per side) plus core. Marty will also send you the tools you need to do the swap.

 

5-Speed Automatic Transmission (01V / 5HP19) - Ross-Tech Wiki

It looks like your transmission control module is coded for...
shifter switches installed
new strategy
DSP active
North American Front Wheel Drive

That should work.

 

It looks like your CAN needs to be recoded from 00006 to 00007 to include auto transmission.

Who was messing with you cars coding? It's all over the road. :crazy:

 

Must have been before I bought it (@133K miles) Nobody has worked on this car but myself (minor repairs, TB, etc), and I have not messed with the coding (yet). Could it be that the previous owner swapped ECU/TCU's without correctly formatting the coding to match the car?

 

I agree with Steve in Chicago, check and correct all the coding as a starting point.

A weak battery or charging system can produce low voltage codes, and may trigger other codes, make sure they are good first.

 

Who knows what happened. I was wondering if it was a manual to auto conversion.
I haven't found anything on the phone coding yet.

On my VCDS, when you get to the page where coding is edited, it'll sometimes pop up a window with info on how to code it. See if your version does that. It's a handy feature.

 

The Mechanical Failure for the brake booster is most likely pointing to the large vacuum tube that runs to the booster in the battery area. I suspect the famous L hose might be busted, or has a nice tear in it giving you that kind of code. Either that, or some other hose has failed. Suction jet pump plays somewhere in there doesn't it?

Yeah, what the hell is up with the coding of your car? Must've been a sick joke... Or a mechanics awful attempt at fixing something?

Just finished up a two day PCV overhaul. Replaced a broken crank case breather tube, valve housing and a plugged up valve. Also cleaned all the PCV lines and the puck valve. Replaced all the vacuum hoses and tested all the check valves. Tried to install the oil pressure sending unit, but broke the M10X1.0 to 1/8NPT adapter, so that will be a project for another day.

I will try to do the recoding later tonight or in the morning. Is this the correct procedure?:

"I had the P1613 code issue a long time ago. My 1999 AEB ECM was coded for an automatic transmission but my car is a manual. The ECM (because it thinks it's in an auto equipped car) tries to talk to the TCM but it can't because there is no TCM. This throws a P1613 code.

Urlik, the ECM in the older cars can be coded for either auto or manual. I guess they went to a transmission specific ECM in later years. "

On closer inspection, my ECU Cover is missing all the screws needed to keep it closed except the one in the rear which was intact, but the cover broke around it. Obviously someone did not know what he/she was doing. no surprise there. headed to the pick-n-pull tomorrow for a new cover . . .

Thanks!

 

That's how to get at and change the ECM coding. The other modules will probably be similar. VCDS might pop up little help windows explaining the various coding options.

To get at that back screw on the ECM box, turn on the key then turn on the windshield wipers. When the wiper arms are pointing up, switch off the key so the arms stop right where they are. Now inspect the plastic cowl at the base of the windshield directly over where that back screw is located. If you look closely you'll find a round plug that can be popped out. With the plug removed you'll have access straight down through that hole to the back screw of the ECM cover.

 

OK, so I recoded the ECU and the ABS and it appears that the recoding was successful. However, the CAN recoding was not. I wonder, did I need to recode in a certain order? I recoded the CAN before I recoded the ABS. Good news is that the ASR light is off for the first time since buying the car

Leaving Tampa for Tallahassee tomorrow. I will rescan and post the results, hopefully no faults will show up and I will be able to get that VT inspection. Thanks for your help Steve. :thumbup:

 

Update: After driving around FL yesterday, my CEL appeared after 310 miles. I am reposting the autoscan below. but first here are some thoughts . . .

1) I can't get the 19-Can Gateway to accept the recoding from 00006 to 00007

2) 17887 Brake Boost Vacuum System: Mechanical Failure
Does anyone know where the fuse for this is located? I want to check the fuse as a starting point, then move on to the pump(located near the ABS module?). I will also check the suction jet pump, but I replaced that when I first bought the car almost 2 years ago.

3) 16706 - Engine Speed Sensor (G28): No Signal
My guess is this is the source of my hard starting problem. Looks like swapping this sensor out is pretty strait forward.

4) I just replaced the battery, so I'm not sure why I'm getting the "low voltaage supply" faults. Maybe I forgot to clear the codes after changing the battery?

Anyway, headed up to Tallahassee. Since today is a holiday, I will have to pick up and replace the engine speed sensor tomorrow. The latest autoscan is posted below:

FYI, the Brake booster pump will not turn ON the check engine light. The only 2 problems you have really (to pass inspection) are the crank sensor and catalyst. Assuming all the monitors are done (check readiness) when you are scanning these.
Are you sure you cleared all the codes after replacing the battery? Or just the engine codes?
You can probably read the VIN with you VCDS and check to see if it's the same with the car's VIN. It's a lot harder to program the VIN in an ECU than to swap ECU and cluster from another car. That way you might know if someone replaced the ECU and cluster.

I cleared the codes after an autoscan, so I assume that I cleared them all

How do I read the VIN using VCDS? I am not sure what you mean by "It's a lot harder to program the VIN in an ECU than to swap ECU and cluster from another car." My gut tells me that the ECU may have been swapped, but I am not sure.

 

When you were in the coding pages of VCDS, did it pop up any windows with help info? If so, read the help info in the 19-CAN Gateway controller to see if that offers any clues on how it should be coded.

 

The window did pop up, but no real indication on how to recode the CAN. The window displayed the following:

"Diagnostic Interface for Datenbus (J533) Coding
+00001 = Automatic Transmisson (through MY 2001 & all PQ24 l Polo / fabia / biza / cordoba)
+00002 = Brake
+00004 = Airbags
+00008 = Steering Aid
Note: Recoding (even with same value) results in refreshing the Gateway installation list"

 

p1750 power supply low voltage

I wonder if this has any connection to the CAN gateway coding issue? The gateway is currently coded for ABS Brakes and Air Bags but not for automatic transmission.

 

After doing some research, some have reported p1750 problems as being related to water intrusion into the TCU which is located under the passenger side floor carpeting. I have had water pooling on the floor in the past. This might be the cause? I'm headed back to VT tomorrow so I will have to find a friend who will let me use their warm garage so I can work in.

On another note. I replaced the engine speed sensor a.k.a. impulse sender. That did not solve my problem and occasionally the car is hard to start. When cranking the motor over, I hear a "clicking" noise in the dash just to the left of the steering wheel. Is there a relay there that is associated with starting the car. I remember from my truck driving days having to replace an "ignition relay" because my Peterbilt stalled on the interstate outside Jackson, MS.

The saga continues . . .

 

Not sure with VCDS Lite but with VCDS, it worked anytime I looked for the VIN.

Go here:

Ross-Tech: VAG-COM Tour: Select Control Module

and click on "engine". The field with Extra should show the VIN (and something else, I forgot now what number is that).

 

I don't recall seeing a VIN listed in the ECU on a B5/B5.5, my 2000 does not.
Your correct VIN WVWVD63B42E371498 is listed in your instruments.
The immobiliser must be matched to the ECU, not the VIN.
VCDS Lite reads the exact same info from the module headers as VCDS.

In the CAN gateway, are you entering the 4 leading zeros, it is a 5 digit code.

 

In the CAN gateway, are you entering the 4 leading zeros, it is a 5 digit code.

You know, I'm not sure. I may have only changed the final digit from "6" to a "7". Tomorrow I'll go out and enter all 5 digits.

I'm back in VT. The last 3 miles of our 3000 mile trip was the toughest. Hit some freezing rain which turned the roads into a solid sheet of ice and left me stuck on a hill. If I didn't recode that ABS module and clear the ASR fault, we would not have made it!

 

+1 on ABS. Now all you have to do is get it inspected
