Car sometimes won't crank when key turned.

[Sterob]

2006 Audi A6 Sedan Quattro, 175 000 km.

Hi Guys,
I seems to have a problem that seems to be slowly getting worse.....

Occasionally, when I turn the ingnition key on, The can will not crank. Dash lights ok. Battery fairly new ( genuine Audi ) No faults on dash.
Can here a faint buzzing( fuel pump maybe?) , but nothing else.

It usually clears after a couple of tries, but today it had to remove the key, wait a few seconds and it started fine. ( I don't think the wait time is relavent...lol)
I have a VCDS cable but have not hooke dit up yet, but will do soon.

To my untrained eye It seems like it might be a worn ignition switch maybe? They do do alot of work over the years.....

I guess Audi will be ready to stab me in the face when I ask how much a new one is.....

Has anyone else had similar problem? Known issue?


I don't know what to check beside VCDS.....

Audi Perth are 200km away so I can't 'pop in'.

Thanks Steve

Thanks jnrdavo, I never even thought of the starter motor. That does seem a possibility.
I just watch a vid on changing the starter.......geez......what a nightmare.....
I don't think I will attempt it as I haven't got a hoist. It would be too hellish.

Looks like I will have to get a garage to do it. dang.

I didn't see any relevant codes in VCDS, but I wasn't sure where to look.
Will have another look see tomorrow.

Whats a starter worth? $350 on Ebay.

not sure if VCDS will show up anything with start motor issues... but I could be wrong!

Not sure if you are a C5 or C6 A6, but VCDS might be able to read the part number of the existing one that always help.. Here is a Bosch one (new) for $300 or so..

Where abouts are you located? I can recommend a good garage in Sydney northern beaches, and I'm sure a few on here can recommend a few others around the country.

looks like superspares have the right starter motor then. Maybe others can chime in on recommended repair places in WA..

Also consider crank position sensor. Its cheaper than a starter motor
