hi, i have a 2008 a4 2.0t and have no check engine light, however, i am still pulling a p0321. the car runs perfect until i get on it, then it will cut out at about 4300 rpm's(in 1st and second i havnt tried thrid) as if i hit a rev limiter. i looked all around and can't find anything about this problem only others with same code but no one is cutting out like mine is. any help is greatly appreciated. thanks for looking!

this also happens while the car is in neutral but not until about 5200 rpm's instead of 4200 when in gear it has intake, exhaust, and front mount intercooler on it and im not sure what else.

What did you find any?
P0321, Ignition/Distributor Engine Speed Input Circuit Range/Performance.

There was an open electric wiring CKT? or I hope you already have a good running and enjoy. x19

sorry for slow response, it was the crank sensor on the driver side of the engine. was a pita to change to and should have been easy in my opinion. lol

oh! this thing also towards the end prior to being fixed started getting worse and the RPM range it would cut out at would vary at any given time from 1500-5k lol very odd and had me puzzled but glad i figured it out eventually.

It's nice to hear. x19

BTW, as we all know that every engine require clean OIL all the time and these debris in your oil are causing built-up the sludge inside of engine which means conventional filter won't remove tiny tiny debris and change oil every 3000 miles. Remember, TURBO require the cleanest oil(cleaned oil) all the time that is. But what will be happening if you could remove the debris from your 3000 miles oil(before change oil) or are you still want to change oil less than 3000 mile? It's better to see the oil cleaning patent device in old post.
Good luck and your TURBO makes more power hopefully.
