whats this likely to be then chaps ?
« on: 13 November 2015, 16:46:13 »
started up yesterday and drove down road and noticed the engine electronic/transmission electronic/immobilizer symbol was lit up.
Car appeared to be in limp mode and it soon became apparent it was not changing gear (automatic).
I think it was in3rd all the time but not sure, anyway I changed gear 'manually' and completed my short journey.
On restarting the light stayed on, so I switched off removed the key and tried again and this time it stayed off and car ran normally for the rest of day.
switched on today and started but light stayed on, so restarted and light now off and running fine.
what shall I start worrying about first please chaps
Thank you.

Need the codes read, probably find an 0340.
Are the LED lights on the auto selector behaving as they should?

Well......do you know if it was in limp mode was the speed limited? or did it just refuse to go in top gear.
If it's gone in limp mode then you would expect a code to be stored.  If it just failed to go in top it could be one of many things relating to engine or box side of things. Early symptoms of cam sensor or Something as simple as temp sensor for ECU would stop it going in top.

Not a lot of help at minute but I'm sure as more information comes out of this someone may be able to give some more pointers.

Being a 2.2 strong money is on the cam sensor...

Until you read the codes you will be pissing in the wind.

Save yourself time and money and get yourself a cheap OBD2 code reader. You will be able to tell us what the fault is then  :y

(My favourite is a Bluetooth dongle (about £15) and 'Scanmyopel' on an Android phone)

Yes it was definitely in limp mode, and it did what it was told when I changed manually.
Nothing came up on the MID and I dont have a code reader so if it persists I will have to find the nearest OOFER who can read em for me.
And the LED lights on the gear selector are normal.
Any way to test a cam sensor ?
Its running fine today by the way.

AndyH,

I thought all these cheap code readers were meant to be crap?

I can only speak as I find. The combination of a cheap Bluetooth dongle and an Android app allows me to read codes and live data for the engine, gearbox and ABS/traction control on my 2.6.

The other tool that people report success with is the hand held Maxscan (about £70 IIRC)

The best tool is Tech2 but it costs approximately £3,500. If you want to code the security systems then it is the only 'safe' tool.

If you just need to read codes then there isn't much risk of doing any harm.

Tried the pedal trick, did'nt get lucky !

Anyone in West Sussex with a code reader and a spare 1/2 hour or however long it takes?

If you don`t get the codes read, when/if it goes into limp mode, pull over and see if the revs are limited to around 3500K. If so it`s the cam sensor

Hi RobG,

Yes the revs were limited, I dont recall the limit but 3500rpm sounds about right.

Harris K Telemacher suggests cam sensor as well.

I need to get the codes read then we shall know.

Codes aren't always conclusive... as likely to suggest total transmission failure as give a cam sensor code... rest assured though, a surefire symptom of cam sensor issues on the 2.2 is spurious gearbox codes ;)

Unfortunately I don't have a code reader :-[

So if it were you then Harris, would you just do the cam sensor anyway.
And presumably I need a genuine VX one.

And could you do it for me :)

If I understand the situation in a right way I had something similar with my AR 25 a year ago. In my case I had to change the "electronic box" in left side of the gear box connected to the selector shaft which goes into the box. System did not know anymore which gear was selected. Had to select manually gears. I opened the box afterwards and realized that the sliding connectors were worn out, remember 300- 400 euro was the price of the spare part. This case have been discussed here, I did not find it yet. Can this be the case?
