Two fault codes - seemingly no symptoms

I hope we're all ready for a potentially useless thread from a paranoid new Disco 3 (LR3) owner...

I just bought this and it makes some subtle groans and whining noises while driving, especially while cold. Makes me worried. I get a hard shift on a rolling stop and re-acceleration. Half my heated windshield doesn't work. The center console vents for the 2nd row don't blow air at all. The heater for the driver (left) side isn't as warm or blow as fast as the passenger (right) side air.

With all of that in mind, I'm getting these two persistent error codes displaying but I don't know what they mean and if they're related to the above symptoms:

U0132-87

U0424-68

Both are saying "test failed, current cycle" so they're not old codes.

Thanks in advance!!

You can ignore U codes in this case

You may have a blocked heater matrix or loose pipe duct

Make sure the air vents are turned on, and select air flow to vents on button

Yeah I wouldn't be surprised if the matrix is blocked. When the engine is FULLY warm it'll be close to the same temp as the passenger side.

No luck with any buttons on the rear vent.


Just wanted to make sure those two codes weren't something I should worry about, especially when there's no issue with the suspension...
