Nemo Broke down again auto gearbox issue

[ohspecial1]

Hi folks

Semi auto so yes manual gearbox with electronics

Stopped at lights into nutral and automatic trans fault

[ohspecial1]

Seems to clear if restart the car and put into manual mode

[GiveMeABreak]

It really needs a diagnostic and them pop the fault codes up here.

[ohspecial1]

Well will be putting into garage tommorow but they are saying its intermittent as they had it couple of months ago cleared the codes and it went on

[ohspecial1]

can i ask are these gearboxes just total crp not even 30k on the clock

[GiveMeABreak]

Yes, avoid like the plague. Stick to a manual or a proper automatic with torque converter. These things are a PITA when they play up and because of their nature can be expensive to troubleshoot.

[ohspecial1]

Well
Will find out tommorow the local garage has said if it needs any gearbox or actuators its to the dealership as it all needs programming

Just wondering if i run it until it dies

Will the manual side be affected

[GiveMeABreak]

Yes, because at some point if the hydraulic actuators that operate the clutch and undertake the gearbox changes fail for whatever reason, then you won't be able to drive the vehicle.

Codes the same

My wife's 07 C4 is almost on 100k and my 12 late Berlingo is at 159k. Both with the piloted box and the only hassle we had was when my wife's car started jumping into gear when the engine was started cold. It stalled immediately, then you could star it and away it went. It took a while to find the cause*, but as I suspected, these boxes don't have a neutral, but rather electrically dip the clutch and select 1st at shut off/start up. The throttle then allows the clutch to be feathered until you are rolling. It's actually quite clever and simple set up, but relies n the sensors.

*The cause appears to have been the crank seal weeping & allowing oil to contaminate the clutch. It finally came to the point I had to change the clutch, but then other nonsense started (injectors wuldn't come out after a glow plug broke & we needed the head off).

Anyhoo, back to your issue. A coil misfire or short circuit "can" cause issue, which is likely why your second error, U1213 is flagging up. The CanBus system requires absolute clean signals and a steady voltage. I would test the battery & the alternator to see if there is any disparity in voltage, charge output and terminal clamps are tight. A slipping belt also caused us some issue recently. U1213 is an ABS/ASC parity/toggle bit error, which basically means the signal from the ABS system is being corrupted. We had an ABS system fault which caused limp home and/or no drive. In my case, the Berlingo had a bad sensor. But I have experienced ABS error with a worn wheel bearing. At 30k I wouldn't neccesarily imagine a worn bearing, but with the sh!t state of the roads threse days, I wouldn't rule it out. I have also seen damaged or cracked reluctor wheels (the toothed rotor that the sensor reads creats a magnetic field which then collapses, it's basically a Hall Effect system) that are caked in rust and catching the sensor.

A few things to check. I cant see why the garage would be suggesting a new box at 30k. Seems someone isn't entirely clued up on these boxes.... Took me a while, but loads of reading and a good bit of personal experience has given me a respect for the system. My latest fun was her C4 and brakes not bleeding I have now bled the system 6 times and still only got an 80% pedal. However, it's sufficient to drive safely & all the systems function. But can I get the bleedin air out? Not yet, but I will....

Hi Well the nemo doesnt have abs not in 2010 model

And the Gearbox is totally crp and mostly only makes 70k
So with having to go to dealership
I would have thought your talking 4k plus not worth it

[GiveMeABreak]

You do have ABS, but you don't have ESP (Electronic Stability Programme).

Marc

Have u known a bad battery to cause any of this issue
I dont mind going out and buying a battery on a chance

[GiveMeABreak]

No further info on those faults which I think I may have advised of previously, unfortunately.

So whether the ABS ECU is sending incorrect speed info to the gearbox ECU that is preventing it from changing gear, I can't say.

Regarding your battery - of course a weak battery can affect systems that rely on a certain voltage to operate, but given the lack of info as to whether this is responsible I can't say. Whether you can try a BSI reset (BSI Reset / Battery Disconnect / Reconnect Procedure) and see if that helps temporarily, again I can't say, but won't make anything any worse. You could have the battery health checked. If you are getting 14.3+ volts into the battery when the vehicle is running, then I can't see that this is going to cause the issue to be honest.

P0750: Gearbox fault - The gear does not engage: Not characterised
P1394: Gearbox ECU fault: Cruise control / speed limiter off request (from the gearbox)
U1213: Information fault emitted by the ABS ECU: Coherence

Hi thanks Marc

Been to many gearbox people and seems they wont touch it with a barge pole

Its more do i drive it until it is un drivable or do i spend getting it sorted

I was shocked at 29k milage i expected like 60-70k
