Ok got an issue that I've been dealing with for a while-getting very expensive & might have to give the xtype up-but really don't want to - but as a husband & father of a three yr old got to have a safe & reliable car - hope someone can finally help me with this headache & I can keep my car -
Well this is it the car is drivable but on highway at times the car will go into a gear fault now all I have to do is pull over & turn car off & on & the fault will go away - I asko notice when I park at times pulling in reverse the car will go into a gear fault as well -

I did read codes two popped up c1155 which is front speed sencer which I replace both sencer & plug/
The second is p0116 which is thermostic I'm thinking of replacing the thermostic housing & flushing the yellow coolent out due to xtype suppose to have orange coolent the reason why I have yellow coolent cause when bought the car from the owner that was already in the system since he had it over 5yrs - I did replace the coolent temper sencer which is located on top I did notice the wires might have some damage as well

I aslo notice the car feels heavy - my Machanic notice that I didn't have oil in the rear differential he did added some it appears I have a slow leakage

Recent fix
I replaced the front spindle to to hitting a pot hole - I have a set of after market 18inch rims low pro tires - bent the spindle this is the same side as the code c1155

Oil change Castrol Edge full Synthetic 5W30-bosh filter

New ribbed breather hose replaced

Replaced mass flow sencer

Upper lower gasket/ spark plugs double platinum

O- ring gasket -

Clean throttle body

Now I notice some fix is pulling the fuse 67 from the passenger glove box but my car don't have a fuse box in side of the glove box even the manual don't show a 67 fuse
Also I don't have a alarm sounder located in the front wheel arch they said this might be the cause but my car which is 04 jag xtype American version don't have none of theses option / now this is my issue can anyone that can understand my issue help me it would be really appeseated

How good is the battery?

A lot of electrical issues are related to a bad battery.

 

Battery is good check it as well some one did suggested to get a thicker ground wire

 

I have read that the transmission ECU can cause these problems. The one on the drivers side.

 

what do u suggest -

Yes 3 months ago I took the ecm & tcm out due to I had a anti freeze leak from the reserver - I ordered a new one But due to delay and transportation Took over two weeks So any freeze was leaking down toward towards the TCM So I took the TCM out and also the ECM out And clean them both up. No signs of water damage or corrosion I waterproofed them and also added Crs spray

 

I've heard it also might be # fuse 67 I'm the glove department but my car don't have a fuse box I'm the glove department as well as no sound alarm in the front wheel arch - my car is an USA jaguar xtype might be Differnt wondering where would be sound alarm or #67 fuse
