update time for the jag, ran well for a couple of months then packed up on 1 August, was going to sshmoke it down to Padstow to see mutha thestags resting place, Well it would be rude not too, with it being her birthday and all that.
Hasnt been used since, sorned in the back of the barn.
It has had a gearbox issue for a while now which I am fairly certain is a microswitch or the selector cable, normally starting it up and running the selector round the j gate twice sees it good.
Anyway so Fatha thestag did that, then low coolant warning light came on, funny that! never used coolant before + I had used it the evening before for an 80mile round trip to pick up Mrs and little* thestags from Tiverton parkway.
* they aint little any more
The expansion bottle was very low, hmmm filled it up and ran the car up and down the lane and the MIL light popped on, arse.
Dumped it in the barn and took the Yeti instead, Mutha thestag would NOT have approved of the frivolity of the Jaaaag. Maybe her spirit knackered it.
Anyway roll on to Sept when I was next in Devon, Battery flat as a witches tit.
Charged it up but it was losing charge almost as fast as I was charging it. Halfrauds did a drop test on it and it lost another 2v while they did that. Utterly fucked. As luck would have it they had another on the counter, exactly the same £130 to you my son. big fucker it is.
Hooked it all up, started it and the MIL popped straight up along with messages about gearbox, traction control and ABS.
Plugged in the ODB reader, the port is a cunt to find, interweb gives about 15 different locations. eventually found drivers foot well up against the centre console tucked up behind the facia.
There was a ton of codes, I find the best thing to do is make a note of the numbers, clear them and then retest, the new ones will be the problem. Cross checked these against the ROM to get a better idea of the fault
P1637 CAN Link ECM/ABS Control Module Circuit/Network
P1638 CAN Link ECM/INSTM Circuit/Network
P1642 CAN Link Circuit
P1643 CAN Link Engine Control Module/Transmission Control Module Circuit/Network
P1646 Linear O2 Sensor Control Chip (Bank1) Bank one is on the right hand side of the engine bay if you're sitting in the car.
And a message scrolling on the screen which read "Trac not available, asc not available, failsafe engine mode, gearbox fault"
Popped it into reverse and it went backwards, popped into drive and it went forwards, then put it into Park and the tacho went to Zero, but the engine was still running.
Check ODB again and a new error had popped up. Still no Tacho though
P0706 transmission range sensor a circuit range performance
Wierdly when I tried to get it back out of park to move it the gearstick seemed to think that the engine wasnt running, goes ping ping ping. restarted the engine and the gearstick moved fine.
Dumped it back in the barn as I had Range Rover Axles to strip.
Looked up all the codes and in isolation it would look like Lambda sensor drivers side, ABS module (know issue with soldered connections) and gearbox sensors. Somewhat bewildered I continued searching but this time for instances of multiple codes.
Another X308 owner had exactly the same issue - right down to the expansion bottle being mysteriously empty.
Also every single error code I have is linked to the CAN circuit, in really bad cases failure of this circuit can prevent access to codes
Item #3 that the pen is pointing too is the coolant level sensor. It would appear to be a friction fit into the bottom of the expansion tank
Here is another unit from evilbay, I am 200 miles from the Jaaaag and Fatha Thestag is in Spain. The smoll hole near the bottom is where the sensor goes.
They have a certain notoriety for popping out and showering the loom and connectors that are situated right below.
So the fix is,
Ignition on, disconnect battery and strap the two terminals together (Jaaaag hard reset)
Pull the expansion bottle and investigate, hope I dont need another - 2nd hand is a futile gesture and Jaag want hundreds
Pull all the loom connectors, clean, hair dryer, lube with lecky cleaner and reassemble
reconnect battery and watch those codes go away
For the gearbox I have found where the two sensors are, how to adjust the cable and if need be how to strip and rebuild the expensive rotary switch on the side of the gearbox
Will be back in 2 weeks filled with enthusiasm and knowledge to fix the broken jaaag.
Then I need to look at the bodywork. Huge
giffer Fatha scrapes on both front corners of the bumper, rust on o/s/f arch and trailing edge of wing, might just get a better wing. and o/s/r arch leading section by the rear door opening.
