Diagnostic advice on non start

Post by DanHolman » Tue 30 May, 2017 13:58

Hi All,

After running the DIS GT1 software; Diagnosis: starter motor. I got the following;

See repair manual,
<TIS> <FRU No. :1 2 4 1 ...>

I went into TIS but can't see how to input the 1 2 4 1 code. Are there any Diagnostic experts out there that know how to use this code?

I imagine its a reference to a repair procedure.

I'm trying to troubleshoot a non start which is increasing in frequency. Inpa has identified 112 cam sensor faulty, but the starter motor may also be on the way out?

I think its both sensor and motor. I've had non start with no crank and non start with crank.

found it. TIS chapter 1241
Check power input,

refer to Technical Data

of pull-in and holding windings in solenoid switch.

Check excitation winding, carbon-brush holder and open-coil
armature winding for short circuit to earth.

Check armature for shorted turns - use a standard test probe.

Checking that excitation winding is not necessary with permanent
magnets.

Basically, 'check starter motor'. I had no idea (and am rather dubious) that DIS and INPA can give feedback on the starter motor on a basic car like the Z3. If you have a recurring cam sensor fault (I assume you cleared the code and it's come back) then change that.
