Help with Code Please

[Rachel2609]

My alarm keeps going off on my 56 plate Sean Leon, I have had a friend look at it with VAGCOM but he cant find any faults.

All he can find is that the last reasons why the alarm has been triggered which is listed as code 128, which he isnt sure what it means, and I am none the wiser I have rung my local stealership and they have quoted £60 + VAT to run a diagnostic which I am loathed to pay if it will come back with no faults found.

I have read the other posts on the various parts of the forum which have given me advice on how to lock to car without arming the alarm, but I would like to get this fixed ASAP.

Can anyone offer me any advice/help/guidance???

Thanks in advance

Rachel, is there any chance you can post the exact fault on here. If I could see the reasons for the alarm going off, it would point to where the fault lies.

e.g, if it was the interior monitor sensors, it would point to wither a fault with them or something more simple.

Cheers

Where abouts are you?

Thanks guys, I am in Sheffield.

I am nipping it back in on my way home from work and will be armed with more details later this evening.

Evening

Have got more info, but think we have got to the bottom of the problem. The fault code was

01135-interior monitoring sensors
004-No signal/communication-intermittent

But we also looked at the doors, and although the drivers door was shut it was registering as open and the interior light was on, whilst the car was still attached to the laptop the light went off and the door was shown as locked, so I now believe that it's the door lock/sensor. Part has been ordered and should be sorted Monday.

Would the dodgy locking mechanism also explain the fault reading above?

Thanks

Hi

Have just had a call from the garage to say that they have replaced the door lock but the fault is still occuring, so they have taken it out as it is clearly not the solution.

He has said that it could be the window motor which is faulty as that sends a message to the ECU???

Anyway, the other thing he said was that the door had clearly been stripped before as all sorts of clips etc were broken, trims etc etc. This would be due I think, to it being hit by another car earlier in the year where a guy hit my wing mirror so hard that it cracked my drivers window and both the window and the mirror needed replacing. So any thoughts on whether the 2 could be linked??? Unlikely, but you never know.

Any advice??

I still think the interior monitoring sensors could be at fault.

When it came up with all of the reasons for the alarm being triggered in the first instance, (Regardless of the component faults) what where the reasons?

 

[longman]

An option would be to turn off the interior sensors and see if the alarm still gets triggered. If there is a fault with them, they could be setting the alarm off unecessarily.

 

[Rachel2609]

How do I do that?

Thanks

Sorry, should have explained that.

Temporarily: There should be a button somewhere in your car that you can press once before you get out and lock it. It turns off the sensors, allowing you to leave a pet in the car so it doesn't set the alarm off. The icon on it is a dot with 3 increasing sized bracket symbols out to one side of it. ( you might need to look in the manual for it, I could tell you in a mk1 Leon, not a mk2).

You will need to do this everytime you get out after unlocking it.

Long Term: You/your garage mechanic could turn them off using VAG-COM in Central Conv. 46 - Adaptation. Might be Coding on a new mk2 Leon.

Then, if after a while you notice that the alarm is no longer going off when it shouldn't, its a good start to solving the problem.

Hope this helps.
