Common Problems with the AU??

Yes, it’s easy. Take the clock fascia off with a small plastic lever and the unit is held in with one screw. The fiddly part is taking off and refitting the tube for the cabin temp sensor.

Once you get the unit out, you can see the bulb holders in the bottom of their little wells. Unscrew and take the bulbs out of them, measure and go shopping to match the size. From memory they are 1.2watt bulbs.

AU2 GHIA 2000 Tickford VCT 4 litre - oil leaks increasing ...
1. Behind power steering pump RH side of motor (supposedly to do with timing chain tensioner).
2. LH side of motor between head and block - approx location 2nd piston from front.
Long-existing oil leaks. Does not use huge amounts of oil but makes a mess. Have pursued this in the past with mechanics - seems it is in the "too hard" basket.
Have owned this car for 13 years, only done 220,000 km. Excellent order. Has had lots of money spent on it, want it up to scratch.
Any suggestions?

Hi all I have a 2000 au series 2 Fairmont
I’ve been having this issue for a while now where it will stutter with anything over 50% throttle. Orgininally I cleaned the o2 sensor with some contact cleaner and it cleared..but it came back so I replaced with a genuine Bosch o2 sensor thinking that was the issue but after 2 days it has come back again…does anyone have any clue what this could be

The next things I’m going to check are fuel pressure reg and coil pack as when I replaced the old o2 sensor it was as black as the ace of spades

In the last 1500kms it has had brand new fuel pump ,fuel filter, leads and plugs.

Thankyou

The inlet manifold gasket is a very common problem with these cars and the issues that you are experiencing point to this may be the problem.

The second most common issue is the coil pack.

See that’s what I thought as well but it doesn’t skip a beat at idle.it idles very smoothly and it’s not high or low…when I’ve got my next day off on Saturday I’m going to check it as well as tps and fuel reg…coil will be the next thing I look at after fuel reg…thanks for your suggestion I’ll let u know how my diagnosis goes.

An AU can idle as smooth as a baby's you know what with a blown inlet manifold gasket.

I've owned a few AUs over time (three of them with now over 300,000ks) and not once have any of them had sensor and/or fuel reg problems. That is not to say that yours could be different.

I have had to change the manifold gasket on each and every AU that I have owned as well as the coil pack. An AU inlet manifold gasket will cost about $25. Even if that is not the problem, it will be good insurance, as it won't be if, it will be when the manifold gasket blows.

Let us know how you go. There are a bunch of us AU tragics on here that are always more than willing to help.

Yep, my sportsman would take ages to crank sometimes, not all the time. I let manifold gasket was the fix. Did plugs, leads, coils etc etc, chasing the problem.

Cheers man for the help Inlet manifold gasket will be the first thing I’ll check tomorrow will keep you updated thanks again

Well here's one for you. AUII Fairlane 5ltr V8 I turned the aircon on the other day and all works fine I can adjust the fan speed etc but when I turn it off the display reads as it should off, the problem is the fan is still on and even when I take the key out of the ignition the fan is still working very slowly the only way to stop it is to disconnect the battery. I am wondering if there is a faulty relay something like that, that is still powder up. Any help or suggestions would be of a great help.

Quick update: replaced the intake manifold gasket turned out it was blown but still hasn’t fully fixed the issue also did a new throttle body gasket with it as well. I think my next go to is gonna be the coil pack is that what you’d would suggest or something else..
Cheers

Thanks for getting back to us. It allows others to read the outcome and possibly help them with a similar problem.

Yeah, I would be changing the coil pack next. Try and avoid the cheaper ones, they can be a little hit and miss.

Plan is to replace it with a genuine vdo coil pack

Hi all, having a bit of an issue with my au thermo fans
Replaced thermo fan motors with tested used ones.
Now fans will cycle in before normal operating temp and will run continuously no cycle out.
Any suggestions?

Have already swapped relays
