    RV Sprinter Trip to Glacier National Park.....with Matt98AHU saving the day !!

    Glad I could help, Harry! Was good luck that I happened to be visiting just North of Bend and had my Autel scan tool with me that talks to everything in Sprinters. Small corrections--I'm not near Portland. At least not yet. Currently have a studio a few blocks from the beach in Newport, which...

    New California smog checks.......

    Looking into this some more, take a read on this page from BAR's website: https://www.bar.ca.gov/ARSC/Newsletters/Newsletter/Spring_2020/Cal_ID_and_CVN_Detect_Programming_Modifications I just used VCDS in the "OBD II" mode (when you first start the application, you have buttons labeled...

    New California smog checks.......

    OK, so I was doing a little homework on this subject last night. I will be making a more in-depth post. Basically, what this boils down to is CARB/smog stations are using "Mode 9" to see the engine computer part number and software version number (which will make up the 'CAL-ID' portion of this...

    Additional CCM coding and configurations with VDS Pro

    I'm not sure which address it is. I never looked that closely for it because that's something that you can change in the normal scantool coding anyway. A 4 door car with 1C0 module and power windows for example will default to a value of 258, you add one to the coding to make it 259 and it...

    O2 sensor locations 2006 BRM TDI Jetta

    There's only one. If your scan tool is telling you it's the downstream O2 sensor, get a better scan tool. There isn't a downstream sensor. Just Bank 1 Sensor 1.

    California Emissions and a Tuned ALH

    Won't fail visual so long as the EGR is still there, OE catalytic converter is still there and the crankcase vent is still intact. Not all places do the snap throttle smoke test. The other part of this is the engine computer has to have no codes stored and all the readiness monitors need to be...

    Steering wheel shimmy at highway speeds, possible dog bone?

    Check the tire balance first at a tire shop. Most speed dependent vibrations are a wheel/tire balance issue. If the vibration is only noticeable when accelerating hard, or is significantly more pronounced when accelerating hard, then it's more likely to be an inner CV joint causing the issue...

    Reverse lights on when car is off

    Pretty bizarre issue. From what I understand, even on the manual transmission cars, the power to the reverse switch is on terminal 15, which is ignition switched power. Furthermore, the signal from the reverse light switch goes into the J519, central electric module. The central electric module...

    CA Smog FAIL after 5spd swap/tune

    It shouldn't be a problem so long as you're also not requesting something like an EGR delete in the tune. Seems most tuners have a hard time getting the EGR readiness monitor to set with PDs when programming the EGR delete. So, when you get it coded and tuned to make everything work correctly...

    Bye California, it's been nice.

    As some have heard me discuss in person in recent months, things have been in motion in the background for awhile to move out of state. Some of my family has moved to Oregon and deegingerkid and I are deciding to follow. It wasn't taken lightly on my part since I have a decent customer base...

    alarm

    Yep. That's what they do. It likely is a bad solder joint or corroded connection inside the door lock module. All the microswitches in these modules share a common ground input. I've had numerous lock modules where they stop recognizing EVERYTHING. They don't see a change in lock position, they...

    alarm

    Sounds like you have a bad driver door lock module that isn't recognizing that you manually unlocked it. The microswitches aren't sending the signal that lets the system know the key unlocked it... Or for now you can just unplug the alarm horn itself. It lives under/behind the wiper motor...

    Best Head Unit replacement 2002 MK4

    I second mk3's suggestion of the RCN210. I've installed a number of them in B5 and Mk4 era cars. They're cheap, very easy to figure out and work well. Some of the more advanced things like importing of contacts doesn't work with Android phones and thus you'll have to initiate a call via your...

    BEW timing belt interval

    PDs were downrated to 80k miles. They originally were 100k rated, but I think VW started seeing an abnormally high number of premature failures before that point, and thus downrated them. When you think about it, the belt does have a lot of localized stress at the cam pulley. It's not only...

    Glow plug control module part # help

    That's normal. Glow plug light should not stay on for longer than its bulb check until you get below about 40 degrees F. And, even though the light goes off quickly, that does NOT mean the glow plugs have turned off. It just indicates that it is good enough to start. You can let it sit for a few...
