I have been running the OSRAM Xenarc Cool Blue Boost D3S Xenon 66340CBB-HCB for six months without any issues. Great light output, color and even distribution. I would recommend Sent from my iPhone using Tapatalk

Here is what I got out of my reader /writer: 3. Body control module---(12), which means 12 errors with a ‘Fault’ status, within my module (s) Here are the additional details I got: 3.1 B1325-03 Control module power circuit - Low voltage DTC history status : History Since DTC clear : Passed and failed Last test : Passed This ignition cycle : Passed MIL status : With regards to voltage in each shock, the looked normal both before and after the clear

I was feeling the same way until I cleared all the codes. I recommend either having the dealer clear EVERYTHING or doing it yourself Sent from my iPhone using Tapatalk

High Guys, I feel your pain! I have had ongoing issues with my MagRide in my 2015 Yukon Denali - BUT WAIT! I have good news! My ride is now (last 2 weeks) SMOOTH as driving it off the lot! Here is a very brief summary of what I did: Had 2 bad shocks, 1 up front and 1 in the back = Replaced all 4x Result: Ride was better but NOT smooth NOT what it should be Took it to several stealerships - No one could "find any issues" Bough this reader / writer: Autel AP200 (TH200) <-- Link to Amazon Best $70 I have spent on the truck Read and Cleared ALL Codes (Especially ride control) Note: I did NOT have any "check engine" codes or lights Result: SMOOTH SMOOTH Ride - what it should be after having new shock all around I am very very happy with the ride in the Yukon again. Note: No matter how may times I asked stealerships to check ride control modules and any low level/deep codes = They all failed, they said they could not find any issues

Sorry for the delay, I did not yet, I emailed WAMs to see / verify that programming will resolve the issue first. I have not heard back from them yet. Sent from my iPhone using Tapatalk

My '15 Yukon started doing this 3 months ago... turned out one of my rear Magride shocks was leaking... replaced both shocks and it resolved the issue. (note i have 110K miles on my '15, i would hope '18 shocks would not be leaking yet)

First, Big shutout to @cmatt and @pgamboa - you two rock! Second, I finally got around to retrofitting my '15 Yukon Denali with HUD (yes, it did not come with it - very early version I guess). Thanks to this thread, a harness from CMATT, and other google searching everything is in and working, sorta... Note: before sending my OEM cluster to WAMS to be programmed I thought i would give it a try, and what do you know "0 MPH" was displayed At this point the HUD will display the DEFAULT view, but when I try to switch to a different view via the "INFO" switch - the HUD goes black - no info and will not come back. It is still working as i can move the display box up and down but no data is shown. The only way i can get the data to display again it by disconnecting the cluster connector (P16) from the back of the cluster (essentially resetting it). After that, the data will display again. Question: Does anyone know what might be causing this? is there something to try? Thank you _Dave
