I took my Disco to the dealer today to have my base idle set because of a high idle condition. Right off the bat it was 99.00 to have the diagnostic done on it which was required weather I knew what the problem was or not. I was not to happy about that. They set my base idle and repaired 2 vaccume leaks and a multi-point inspection. This is what else they found.
1) Transfer output shaft seal is leaking was leaking (I did not know because I park on grass/dirt)
2) An engine oil leak (very small I knew this)
3) Power steering leak (I knew this future repair)
4) 3 out of 4 tie rods have play (I did not know this)
5) Rear pinion seal leaks (did not know this same as 1)
6) Driver side Tail lamp was not correctly fitted.(I did not know this)
They also said that the following codes might be needed to be looked out
1) P0102 MAF circuit low input (drive cycle A) I have no clue
2) P0125 Water tempture sensor- no warm up fault (drive cycle B) I have no clue
3) P0130 Oxygen sensor circuit slow response, upstream sensor bank A (drive cycle C) I have no clue.
4) P1138 Oxygen sensor problem with switching lean,sensor(s) for bank A (drive cycle C)

 

Ran out of room. I got all that from the dealer and it was only 99.00 I was very happy. I did turn down the car wash which was included. I feel that Cape Fear Land Rover did me right. My Disco runs very well now I just need to fix a couple of more things. I need some help understanding what those codes are. They also said I was getting near my 120000 service. What is the 120k service. I am at 117000.

If you want some help with this get back to me.

 

Well the 120k service will be the same os the 60k service.
So your check engine light is on I take it?
The two drive cycle codes are for just that, drive cycles, if you dont drive it enough then these codes will be pending, repeated short trips for example will set "soft" codes in the ECU because the engine and emissions system is not getting up to proper temp.

SO answer me this, how do you use the truck? How often do you drive it and how far do you drive it?
Once a week to the bingo hall or to work every day 20 miles away?

 

I bought the Disco in Sept. 08 and did the 60k. I dont drive it that much I dont put 1k a month on it. I use it for light off road and when I need more room than my Accent has and does not require me to use my F350. I would like to make everything right on it. I just put the Lucas power stearing additive in it 2 weeks ago and that leak is almost over. All my oils are synthetic(mobil one). They cleared my codes but the light came back on in about 50 miles. They said this was going to happen and the cause was most likley the oxygen sensor. I do need to change the Tstat and I do have a little oil seeping from the valve covers. I am a good mech. I rebuild helicopter engines for a living so I am up for anything.

 

Replace your t-stat and then once a week drive the truck for 20 miles or more on the highway so that EXERY thing gets good and hot.
Do this for the next month, every Sunday go for a drive.
Clear the codes and then see if they come back.

 

Get your 02's replaced, they are past do.
Check the exact work done on your 60K against my list then do all the remaining work, like replacing the plug wires, induction cleaning, additive in the gas tank any anyting else
Not yet done.
I agree with Spike, replace the t/stat as well as replace the upper radiator hose with the new 3 piece hose set along with the new black plastic t with the bleed screw included.

 

He does not need that new "T" upper hose thingy Mike, he has a DI.
Replace ALL your coolant hoses.
AtlanticBritish sells kits for this.
I still say that she just needs to be driven more because your cats are not getting hot enough and that is what is setting off your O2 codes.

 

I will replace the hoses. Everything else is done except the Tstat. The Disco runes very well with minor leaks. When I do drive it my trips are 48 and 62 miles one way all highway (60mph). I am sure the O2 sensor needs to be replaced where would the bank A up stream be located?

 

Up stream is in front of the cats and downstream is behind the cats.
