Try uplugging & cleaning the two round electrical plugs at the top front of the gearbox. Did you do the fluid at correct temperature & engine running ?

Surely unplugged it can't go off, so do the resistor fudge & leave the airbag where it is ?

I use one of these. Decent lenght probe makes it easy to reach awkward bits. Neilsen CT0998 3pc Mechanics Stethoscope

Assuming the Nanocom is reading the ECU correctly, then surely "right side airbag" is the one in side of the seat back ? Hence the connector under the seat, not the steering wheel clockspring..

Rather than wriggling the connector, check the contacts. Could also be the airbag open circuit. You could wire in a suitable resistor instead ?

If the motor runs, but doesn't unlock there's probably stripped gears inside. Most P38 latches suffer failing microswitches, but the motors do fail - mainly the brushes. I have repaired some of mine. There's about 6 or 7 screws holding...

Take the spark plugs out (distributor cap seems to be missing ??). Then crank it on the starter motor & check the oil pressure and get the oil circulated where required. Then I would put sparkies in & get it to fire up & idel before revving it up.

Certainly @MGT is ignoring the thread !

There's a >1999 on eBay for £300, but the pictures are blurry so who knows what condition.

From that graph, it appears that Bank-A is the bad one, however the Nanocom recording you share indicates Bank-B is not swinging through the correct range. This why we suggested swapping them over & cleaning the connector contacts. They should...

Would an Italian tune-up help ???

The O2 sensor data looks wrong. They should be switching at similar rates, so maybe it's time to put new ones in ? All the other charts appear ok to me, but it's dificult to tell from the pictures. As I said before it's generally not...

surely that would not work because the join is well before the centre box.

I might be in Reading next week, but don't know what day yet. If you're nearby I can bring my Nanocom.

Nanocom also shows BECM inputs including the window switches. That together with the ability to activate outputs to test the windows & locks means you can nail down where the fault is.

Not usually. Two Cats feed a single centre box, that then splits to two rear boxes. But saying that my MOT guy did find differences in the two tailpipe emissions !! Even he agreed it didn't make sense.

GEMS definitely has separate trims for each bank. Don't know about Thor. The pics above do show trim values, but the recording Pete12345 sent shows zeros ?? Also Nanocom is labelling them as Downstream when it should show Upstream Trims...

But that one didn't tell us to ignore it . . . hence we actually did ignore it.

Similar threads are available. Just to keep.it balanced.... https://www.landyzone.co.uk/land-rover/duplicate-please-delete.398546/

None of those show the O2 sensors. As said several times now, emissions depend on O2 Sensors, MAF, Engine speed & Temp, plus Air Leaks and how the trims are behaving. Not got one, but from various forums it appears Thor are much more...

Another thing to try is to use Nanocom Instrument Mode for recordings. Select Instruments & Motronic. Make sure Auto Recording is OFF. Then start the car & enable recording. Here's an example of the recording from one or my P38's. This...

I'm still ignoring this

Well that data shows essentially the same as post #30 above. Both O2 sensors are switching, although Bank-B voltage range is lower than Bank-A. My understanding is this shows the air-fuel ratios are adjusting more on Bank-A, but not sure...

Rather than uploading lots of duplicate pictures that don't show dynamic values, just upload the recording file from Nanocom. Make sure you do the recording at Idle & 2500rpm. Before you upload, change the filename from "xxxxx.csv" to...

BTW, re the thread title, what is "faked" ? or did you mean "failed"

Unless you have O2 sensors after the CAT's (i.e. 2 pre & 2 post), don't bother with the Downstream values. Main focus should be these values: Upstream Bank-A & Bank-B Short term trims Long term trims MAF Throttle & RPM Is the ECU in...

ok. Ignoring . . . .

Pressure test with engine hot & not running ?

Fixed it . . . .but your reply doesn't update
