I have a C1A67-78 (sensor alignment) error. It seems like JLR says the first step (if clearing the code won't work) is to try running the alignment routine - then if that doesn't work, you have to remove the bumper and check the support bracket. I sort of doubt it was hit, so want to try the least invasive process before removing the bumper cover.

 

Have you tried clearing the code first?

 

The dealer did, but the code came back. The service advisor said that it's usually the bracket and I guess because it's "damage", they weren't warrantying the labor to remove the bumper cover. After I picked up the vehicle, I checked online JLR Topix and it seems to suggest the next step should have been to try and run the software alignment routine anyway, and only if that doesn't work THEN move to assuming the bumper/bracket.

 

I would take it back to the dealer and let them know that the car sustained no damage and that they should proceed with running the software alignment routine. If the service advisor tells you otherwise, ask to speak to the service manager or the owner of the dealership. Good luck.

 

Did you figure this out? Have this on a 2020 Disco and LR dealer wants $1200 to replace the bracket with no indication this is the actual problem. Car was not hit unless by a shopping cart or something, so don't see how the bracket could be damaged.

 

Oops I was only able to see the first post - replies weren't displaying before I created an account.

I will ask dealer to do the software alignment routine...

 

Yes, I have one of those BT horoscope kits you can connect to your phone and I was able to look behind the bumper. I bought a new bracket for $35, but wound up not needing it - the bracket itself was fine, but for some reason the sensor "cube" (which just snaps into the bracket) had fallen out of the bracket. I did have to remove most of the fasteners holding on the bumper (but didn't need to completely remove it or disconnect anything except one of the washer-jet hoses) in order to have enough room to reach in and push it back into place. The sensor snapped back into position just fine. After that you have to initialize a learning routine to check the calibration. I tried an inexpensive OBD tool, but it wouldn't work, so I returned it and bought an Autel MX900 for $560 on Amazon, which did the test/alignment just fine. I assume I'll get some other use out of it here and there and it was still way cheaper than having the dealer fix it. They quoted $1500 for the job too.

P.S. once you use the tool to initialize the calibration, you have to drive around a bit for it to re-learn ... it can be surprising how varied this will be. Sometimes the test completes quick and other times it could be 30-50 miles before it completes and you know for sure. The Autel will tell you the alignment angle and there are specs for the range on TopiX, so you'll know if it really is a bent bracket or something else.
