Help - Fault Codes

B6/7 S4/RS4

;D ;D ;D Back on the road again… Isn’t there a song called that.

Well… we finished the job this morning just before mid day, cleared all the previous codes that had caused us to half remove the engine again, took if for a drive (About ten miles) ran perfectly, really strong on torque and power.

So, I took it home, gave it a really quick wash and then went for a long drive, steady for about the first ten miles and then gave it a little more and gradually started to increase the rpm further up the range.

Suddenly when accelerating hard in third gear I felt the engine flutter and hesitate, and a loss of power. So I slowed down a little and pulled into a service station, got out my little VAGSCANNER and checked if I had any fault codes… Sure Enough : 16405 bank 2 camshaft a (intake) p0021-002 retard setpoint not reached (over advanced) mil.

F-ck…Sh-t… and a lot worse… So I cleared the code and started on a very disappointing drive home, BUT suddenly after driving for about five minutes and deliberately driving on and off the throttle, full power returned and the responded perfectly to the throttle. So I decided not to go home but continued on my driver for another hour in all types of roads and traffic, clocking up over 50 miles… Without any further problems. Arrived home, checked everything physically, ran another scan, NO Fault codes at all. Went for another thirty minute drive, no problems at all.

Oh I’m hoping whatever it is has sorted it’s self out.

I did wonder if the pistons in the actuator/solenoid could be a little tight, being brand new and maybe now they’re bedding in.

I’m certainly hoping so.

Just going to let the car cool down so I can start it from cold and go for another run tonight.

So, for the last sixty miles she’s running perfect, after that one hiccup… Keeping my fingers crossed and it is so nice to have no timing chain rattle on cold or warm start up.

Here’s a few pics of today, back on the road at long last. Haven’t really given it a good clean yet, but what the hell.

I’ll keep you informed…

;D ;D ;D ;D ;D Anther Drive… Still running perfectly and no fault codes. ;D ;D ;D

Congrats it’s a great thing to go threw all that. Do you have a jhm tune…If you do it triggers a code sooner then stock would to keep you safe from chain disaster. Expect to see that maybe one more time. For whatever reason that L version of the adjusters are very tight.

The car is sooo good looking it makes it all worth it.

Thanks Justin

I believe that could well have been the issue (Piston in the solenoid/actuator) may be a little tight, now with almost a hundred miles of running the fault hasn’t come back again.

I will be emailing Jake at JHM on Monday to get the download.

Unfortunately I only have a Window’s 8 laptop, but Jake has told me that it has worked ok for others, and if I do have an issue, it will be downloading the file into my computer, not when I download it into the car.

I’m going for the 93, as I can always get high octane here in England.

Oh and many thanks for taking an interest in the job and giving advice, it’s nice to know that someone who know’s more than you is watching… LOL.

JHM Tune (93) is ordered… :wink: :wink: :smiley:

Still running fine… This part of the story is now complete.

Thread now moved on to here… http://audirevolution.net/forum/index.php?topic=2745.0

It’s great to see a happy ending. Funny how AZ had nobody over there that was of any help. It’s nice to see more and more people are getting help here and helping others with issues find the help here.

Yep… I’ll be staying here and hoping to help/contribute

Many Thanks

Jim
