We need some specifics to be able to help.

What lights, in what situations?
Have you scanned for codes? You MUST have that ability.

It should all be solvable, assuming you don't have some sort of catastrophic level of failure going on.

You have entered the Rover Club. Land Rover G4 plus lights on the dash.....now if you have a few oil drops on the driveway we can make it official! For starters, what parts did you change and what led you to change them? Having the correct code reader is going to be key. Looking at your dash, you have the Three Amigos (ABS, Hill Decent, TC). You need a code reader that can provide a proper reading. A Nanocom is one unit. I use a iCarSoft 930. Both units can read and allow you to reset/turn off the ABS light once the problem is fixed. A simple and cheap option for codes is a Bluetooth OBD and the Torque App. Although this unit will not read ABS faults for the Three Amigos. After resolving that I would look into doing Option B for the ABS Modulator if it hasn't been done by previous owner(s). Search the forum as this has been covered. You can also rent a Nanocom from board member @Extinct Either way you need a proper code reader to determine why the Check Engine Light is on and what codes it is throwing. The BRAKE light can be part of that hot mess w/ the Three Amigos.

As WindyCity and I already said, you must have a PROPER OBDII code reader. Some do not do a good job with our trucks. You mentioned that there are no codes currently. That is not true. To have those lights on you DO have codes. (unless there is some catastrophic level of failure somewhere) Those codes are incredibly common for us.

- Service Engine Soon (SES)/ Check Engine Light (CEL) means that there is an emissions related error. You have one or more codes related to that.
- Three Amigos are Traction Control (TC)/Hill Decent Control (HDC)/Antilock Braking System (ABS). A common error. You can find tons of info in the forum on this. There can be a couple of different solutions depending on the codes you find.
- Brake Might be related to the Three Amigos and might be a different issue. Read the codes.

An important thing to know about our trucks is that they are VERY sensitive to low Bat/Alt voltage. A bad charging system will cause many spurious error codes. If your battery or any part of the charging system, including cable terminations and ground connections are questionable, you will get spurious errors. Don't chase ghosts, fix the charging system first if it is not up to snuff.

Since you say you have already changed parts, I recommend clearing all codes and driving to see what returns. Then work those.

Good luck.
