Limp mode (M + S lights), P1884
 

I brought my 2000 discovery 2 to the shop for a water leak. They found a broke engine mount, etc. They finished the work, picked it up and half way home i noticed the MS llights flashing I do not know if they were flashing from the start or not (they fall between my eyes and the steering wheel). So, I inform them of the situation, and he ask me to disconnect the battery and a couple of fuses. So, I say how about I bring it back in and you take care of the situation...To make a long story short, I retrieved the vehicle and will recoupe my funds from the shop by other means.

I have had these lights before, but they were hit and miss until I found that it was the battery terminals. Now the lights flash as soon as the engine cranks. Another thing that wasn't present before i brought it to them is the fact that when i cold start the engine, it idles really high and then gradually goes down to about 750....if i put it in neutral it dips even lower. Put it back in drive it stays low.

Any suggestions are much appreciated.

The M+S switch on the side of the gearbox is a well known problem, as is the harness rubbing at the P clip on top of the box causing a short

Have a look at the link above which explains the switch

if it is a V8, is it shifting or just staying in 3rd gears?

XYZ switches are 99-04 = same thing. The brown unit cost more vs the newer black unit's. I've personally had better luck with the brown/tan units vs the newer style black ones. Either unit will work on 99-04 D2's.

Once you replace it make sure it's adjusted good or you could still get M&S flashing. Also for peace of mind get a meter and check the voltage of your batter with the engine off and on. Off you should be 12.1-12.9 and running it should be 13.4-14.4 depending on the electrical load.

You need to either activate the ABS modulator to get the air to pass thru it and then bleed all 4 corners, or go have it bled somewhere they can activate the modulator as they bleed it.
