Default I video taped with my phone but the sound does not come through on you tube.

I taped 3 attempts so that you guys could see that it does the same thing every time. No start first crsnk, start second crank. I don't know if I mentioned that if I shut it off and immediately start, it starts like lightning.

If it is a cam sensor could the behaviour be so predictable?

Default It will not hurt to change the CPS. It's only $80.80

I'll see what happens after that.

Default Meh, I have $78.50 here--->

<a href="http://www.germanautoparts.com/Audi/A8/EngineElectrical/45/1">German Auto Parts</a>. Pay no attention to their note, you only need one sensor. I hope that does the trick. It sucks to have to throw parts at the car though.

Default Re: Meh, I have $78.50 here--->

So far this week, FPR, switch and I'm ordering a CPS. The car has 117K this is all stuff that would have probably failed in due time. I lie to myself and call it preventive maintenance.

Thanks for the heads up ricoblanco.

I have ordered parts from here lately. This guy actually answers the phone and will call you back, something unheard of lately.<ul><li><a href="http://www.foreignautomotiveparts.com/RenderScriptTemplate.epc?_cmd=epccat_VehicleWHD&am p;cookieID=2HB0HESZV2HB0HLRE5&amp;yearid=1999%40%4 01999&amp;makeid=AUDI%40%40AUDI&amp;engineid=13525 62%40%40A8+QUATTRO++%2F+V8%2D4172cc+4%2E2L+GA

Default Re: How do I diagnose?

I agree. I think an injector is leaking down. A couple of ways to diagnose. First with a fuel pressure guage hooked to the outlet of the fuel rail (where fuel pressure regulator sits) Turn engine over a couple of times; turn off and watch pressure guage. Or, pull injectors and rail up; turn engine over; turn off and watch tips of injectors for fuel drip. You might try putting in a bottle of Red Line SL1 in first to see if that clears something out. (Pour the whole bottle into the tank) Peter

The signs of the leaky fuel injector is a lot of smoke at start up and fuel in the oil.
