    Wireless Charger upgrade/replace old factory unit with pics

    I bought that Carqi Wireless charger for my Regal and it will fit the Commodores too. The consoles are the same, you guys just have a lid over the cupholder and we don't. The whole cup holder assembly is replaced by this product. I did not plug in the wireless portion... I just wanted a better...

    Looking for Help Acquiring Parts

    In short, I am simply being particular. The exhaust components do differ between the GS and the VXR. Given the option, I would much rather use an OEM component to achieve what I am after vs. chopping up my own exhaust or going the aftermarket route (which we all know is almost nonexistent). I...

    Looking for Help Acquiring Parts

    Hello All, I have been trying to acquire some Commodore ZB components but have found it very difficult to find sellers willing to ship out of the country (understandable). Most licensed Holden parts dealers are not allowed to ship outside of Australia due to licensing agreements with HSPO...

    Engine Undertray

    Exactly right, it just depends on the engine whether the skid plate is there or not. The front subframe is identical across all Insignia/Commodore/Regal. So yes, the provisions exist to mount a skid and anyone could purchase the four clip on U-nuts, bolts, and the skid plate itself. I...

    Engine Undertray

    My 2019 Regal GS with the 3.6L has no engine underbody tray/splash shield either. In my market, all of the 2.0T equipped variants do have one.

    There's still a pumpkin with diff. fluid. The clutch packs are a separate system with their own fluid.

    ZB Commodore - Warning - diesel brake pads sticking to the disc rotor?

    Yeah I'm starting to realize that myself. I've always liked the new and shiny things. These past couple years have shown me where things are headed with an unsustainable reliance on semi conductor chips, IOT, and complicated software systems. I'm finding myself becoming more attracted to the...

    ZB Commodore - Warning - diesel brake pads sticking to the disc rotor?

    Hopefully pads are not going in that direction. It's bad enough most OE tires don't make it past 50km. Here in the States, my brother has a 2016 Chevrolet 2500 with over 160km on the clock. It's a farm truck that sees frequent towing, with and without trailer brakes to assist deceleration. The...

    9 speed Transmission Flaring

    On particularly cool mornings, I have noticed a bit harsher of a shift in those gears. I have had that "characteristic" from day one. My service manager even asked me if my vehicle had that symptom... I didn't even provoke the question, it was just out of the blue. It may be a common...

    ZB Calais Tourer Is It Worth The upgade

    This is one of my only complaints from an ergonomic standpoint as well (at 6'3"). Incredible headroom, there's almost endless seat adjustment, and the steering wheel adjustments are adequate. The dead pedal is far too close when I get situated. I know it isn't the safest thing to do, but on...

    Replacement rear compartment courtesy light.

    Minor details :p More or less just showing they are available elsewhere (vs. directly from Holden). Is there no equivalent parts website down there?

    Replacement rear compartment courtesy light.

    Is this the part you are looking for? GM Parts Direct says it is not compatible, but I just pulled the courtesy lamp out and verified that the P/N matches. $28.73 sounds a bit more reasonable. https://www.gmpartsdirect.com/oem-parts/gm-courtesy-lamp-13503059

    9 Speed Auto...

    I have found the transmission to be on point in almost all regards. I've used adaptive cruise in exactly the same scenario as described and I have never noticed any "doughy[ness]". Cruising around in 9th gear at 1,000-1,500 RPM is great for flat roads but it's silly to expect a nearly 1,800kg...

    @TeePee53 is spot on. Only the Insignia and Commodore VXR are 5x120. ALL other Insignia/Commodore/Regal variants are 5x115, including the Regal GS.

    Issues zb

    I get more of a clunk than a squeal. It happens with every cold start. I have discussed the noise with my service manager and was informed it is normal. They say the noise is caused by the injectors/timing actuators being pressurized after sitting or something along those lines. I don't...

    Is there a way to disable the alarm but still lock the car?

    The app is on Google Play or the Apple store. As far as the car side of things, there's no sort of profile you can set up? For if there's more than one driver for example? Here's what the app looks like:

    Is there a way to disable the alarm but still lock the car?

    You have to have an account, whether it's through Cadillac, Chevrolet, Buick, or GMC. You just download the corresponding app, sign into the app, sign into your account in the vehicle, and everything is linked up. But, I'm not entirely sure if OnStar is required for that. Do you have accounts...

    Is there a way to disable the alarm but still lock the car?

    ...One would think, but who knows lol Odd the info isn't in your version of the manual. I looked that up in the Buick app for what it's worth. TANGENT: Do the Commodores have a similar app to access the manual and other stuff? If not, I wonder if the Buick app would work.

    Is there a way to disable the alarm but still lock the car?

    According to the manual, the only way to achieve this is to lock the doors physically using the key (not the fob). I've never tried it, but it's simple enough to pop the cover and lock the door. I've done that a few times when programming a new fob. Not sure if that also disables any "motion"...

    ZB Gearbox issues

    That's an interesting graph. I would assume many other sedans follow a similar trend. Our Regal sales are similar to yours. I don't want to get too far off topic so I'll just post the link to a chart here for anyone that's interested. While our sales numbers are barely worth noting, the amount...

    ZB Gearbox issues

    I'm amazed that there have been no reported trans issues with the Regal GS. Some relatively new info indicated that only 1,319 were sold in the US, so maybe it's just the small population and and even smaller sample size on the forums. I have praised the trans and it's reliability thus far but...

    Auto Folding Mirrors - Standard on RS or RS-V?

    Be grateful, we didn't get them on any trim in the US. Buicks are marketed as "affordable luxury" here and while that largely holds true, they stripped the Regal of many luxury items available on the global counterparts in favor of affordability.

    ZB Screen Surround Plastic

    After downloading the service manual @stooge supplied, the info you're looking for is on page 1183. Search "instrument panel trim plate". In order to get to that point, you'll have to remove a few other trim pieces first though. I had to remove the same trim pieces covering the screen...

    Rear diff noise...

    Interesting... do you have more info on that? Unfortunately, from what has been shared on the Buick forum, the issue is not limited to the V6. There have been about a half dozen folks with the I4 speak up and only one with a V6. That's not statistically significant given there are far fewer V6s...

    Rear diff noise...

    There have been a lot Regals going through rear differentials. It sounds like you have some of the same symptoms described by the Regal owners, so be prepared to have the entire differential assembly replaced. Check out this thread for more details: Joining the Rear Diff Club

    Used ZB RS 3.6 - Hiper strut suspension

    Any difference between 18 and 19 MY?

    If we're strictly going by the 3rd VIN digit, ours are branded as a Buick (4) in the US. I didn't realize until now that the Commodore ZB is branded as an Opel (V)... weird. The next few digits narrow down the Make/Model regardless of what the 3rd digit is. But to answer your question, ours...

    Actually yeah, that's correct, but it is Android-based. Full on Google Android Automotive OS isn't gonna be available until later on, which doesn't apply to us.

    Software Upgrades

    It also somewhat depends on which software the car has, at least as far as infotainment goes. If it has the older Blackberry QNX software (early 2018), not even the Regals are receiving updates. The new Android Automotive Android-based OS software (late 2018 and on) is being put in almost...
