I have a problem with immobiliser when I start the car.
When I turn the key the immo light starts flashing.
I need to try to turn the key few times before it works.

Sometimes I have a problem with remote opening the car.
I need to open it with key and turn the ignition on to unlock the rest of locks.

Scanned it with vcds today and it shows following codes:


Address 16: Steering wheel Labels: 8E0-953-549.lbl

01176 - Key
07-10 - Signal too Low - Intermittent


I can't find much about code 474. Checked Wiki and anything that comes up on google but nothing really.

Second code is explained on wiki

01176 - Key: Signal too Low

Possible Symptoms

Malfunction Indicator Light (MIL) ON
Possible Causes

Immobilizer
Wiring and/or Connector(s) from/to Immobilizer Reader Coil faulty
Immobilizer Reader Coil faulty
Immobilizer Transponder in Key faulty OR incorrect Transponder in Key

Remote Control
Remote Control Battery low
Remote Control faulty OR incorrect Remote Control used

Possible Solutions
Immobilizer
Check Wiring and/or Connector(s) from/to Immobilizer Reader Coil
Check Key Immobilizer Transponder Status
See Measuring Value Blocks (MVB)
Check/Renew Immobilizer Key Matching
Check/Replace Key

Remote Control
Check/Replace Remote Control Battery
Check/Replace Remote Control
Special Notes

This Fault Code can be stored in due to Remote Control or Immobilizer Problems. On most Models these systems are separate and should therefor also be diagnosed separately.
In case of Engine Starting Issues please make sure that you are really experiencing an Immobilizer related Problem! On most models using conventional keys, the Engine will still start but cut out after 1-3 Seconds if an Immobilizer related Problem is the cause. On models using Kessy Systems and Electronic Keys, most systems in the car won't power up at all if if an Immobilizer related Problem is the cause. If you are NOT experiencing this behavior (e.g. Instrument Cluster powers up, and engine cranks but doesn't fire at all or engine won't crank) this is likely NOT Immobilizer related.

When found in Audi A3 (8L), Audi A4 (8D), Audi A6 (4B) or Audi A8 (4D), check Wiring from Immobilizer Control Module to Immobilizer Reader Coil. A known issue would be the Length of the Wiring, an optimized Replacement Part may be available (8D0-972-275).
May be stored in Combination with 17656/P1248/004680 - Engine Start Blocked by Immobilizer in Engine Control Module.


Any advice what I should start with?
Wiring that goes to the barrel? Should I change it?:sadlike:
 
I didn't yet. Can it be a cause of the problem?

If you read the 'Possible causes / Possible solutions ' again you will see 'key signal low' and 'remote control battery low'.

This is the first place to start and the easiest and cheapest.

Change it and see if it fixes the problem - nothing lost ( apart from the odd quid ) if it doesn't work !
 
will do
thanks
 
I've changed battery in the key. Also noticed that one of the metal pieces barely touches the battery so bent it a bit.
I have started the car few times yesterday and today. There was no problem with immo even once.
Also scanned it today and it doesn't show error anymore so good times!
 
battery has nothing at all to do with immo, but will have affected the locking/unlocking.

Its more likely the slight movement of components allowing the glass bead to give it's signal properly.

I think you're wrong :yes: !! ?

In this case of course :huh:

I am not.

The Immo capsule is completely seperate to the remote section.

The immo is passive and the capsule vibrates at a specific fequency when the signal from the immo loop acts upon it,the reflected signal is then picked up and the immo disabled. Try it, remove the remote bit of your key and go start your car.
I just have it's perfect as expected

Maybe so pal - and I've changed key fobs in the past and know you have to change the capsule over as well otherwise it won't start - but in THIS case it seems like a hell of a coincidence that taking the most obvious and easy and cheap route of changing the battery, which was identified as a problem on the scan, has sorted the problem !

I know the immo is separate but, in this instance, the suggested solution worked for the guy.

What would you have suggested to try first - had you bothered to reply ?

First off i am not your pal, and had i bothered to reply as you call it, i would first have to have seen the thread which i didn't see till today hence my answer.

I suggest you wind your neck in and pat your self on the back that changing the battery in an unrelated system magicly fixed it
 
The first thing i would have tried was a spare key, assuming there is one. That would eliminate the key, and narrow it down to a reading error.

It's more likely clearing the codes has temporarily fixed it and it will re surface shortly

The codes suggest a wiring,connection error from reader to immo/dash

If the steering wheel module connection is poor the signal will be low won't it?

Fair comment - spare key first if you have one.

I suppose I assumed the codes had been cleared. Moral - Never assume !

Surely, as a matter of expediency, a new battery would be the next obvious try wouldn't it ?

Sometimes it's a " wood for trees " problem that can end up too complicated !
 
Just to let you know guys.
After changing the battery I have driven the car for a day and there was no issue with immo not working properly.
I didn't clear errors at that moment.
It works at the moment. I have cleared errors yesterday.
To make sure it did work I will wait few days,scan it again and will let you know.
No point to argue about it.
 
Cheers mate - hope it continues ok.

Sounds like from the other comments it was 'pot luck' but also sounds like the battery needed changing anyway !
 
Ah so xmas makes all the difference huh :)
 
yesterday i was a stranded due to a immobilizer fault. same thing the car will not start when the yellow light is flashing but will fire up then die after a couple of seconds, it is a intermittent issue.
after reading the threads hubby today is going to change the reader coil. God i hope this works as if not he said he's gonna break her 4 spares :(((
I LOVE MY CAR.

Did you solve it? As the immobiliser can be removed from ecu if all else fails.
 
Yes & leaves the car allot more vulnerable, not advice I would give out tbh.

Did your partner change the reader coil? Did you need the keys reprogramming? I'm having the same issue but don't want to buy new keys etc also where did you get the reader coil from?? :/ many thanks
