Hello all,

I appreciate my car is not a R32 but I have had no luck on the Audi forums so need some help please.

Car: 2006 A3 3.2 Quattro DSG, Engine Code BMJ

I bought this car after the chain had been replaced, the car was misfiring heavily and the owner had got sick and tired of it. I checked the MBV's and thought to check the timing first, I found it was incorrectly set as the intermediate pulley was half a tooth out. I also found that the filter on the camshaft adjustment unit was damaged, I repaired this with the same grade mesh, stripped down the camshaft adjustor's and adjustment unit rebuilt and put the car back together.

The timing was set correctly, the car start and idles fine (checked cam positions in MBV's) but does lacks power. Looking at the measuring blocks below it appears that the camshaft adjustment unit is faulty, as the cam timing is not being adjusted as the ECU specifies. I am thinking it could either that the cam adjusment unit is getting any oil, or I have not put it back together correctly. Does anyone have any experience on this? Thanks

Interestingly enough, I had VVT issues on my Audi BDB engine (the earlier version of yours). When my intake cam wasn't advancing, it was because the actuator solenoid wasn't working. It made a loud buzzing noise (they're normally inaudible). If I tapped it with a hammer, stopped the engine, then restarted it, it then worked. Can you hear any buzzing noises from your solenoids?

Your cams are a little advanced actually. They normally sit at -3 (intake) and -1 (exhaust). I think you may have advanced the cams a tooth?

If not that, then I guess it must be to do with the VVT unit. Maybe get another from ebay but it needs to be the same part no as yours.

Hello,

No buzzing noises from the solenoid valves but when I perform an output test using VCDS I can here the clicking which indicates they are working.. As the filter was damaged I stripped down the valve timing unit and think I have not set the position of the little valves inside correctly. I was hoping somebody knows how to put these back together as ELSA has no information on it.

I do not think it would idle as well as it does if the timing was a tooth out, I locked the cams in position, checked the marks on the cam adjusters turned the engine over and everything still lined up.

Yes I did replace and set the sealing rings 120 degrees apart on the camshafts.

Will be stripping it down this weekend and performing an output test on the solenoid valves while the unit is disassembled to make sure how far they travel and then set the pilot valves accordingly.

Regards
Khurrum

R32s can run fine a tooth out (many already do from the factory), as did the previous 12V VR6 engine, but fair enough, you sound like you know what you're doing and we can outrule the cam timing.

It can only be, as you say, how you've rebuilt the VVT variator unit. I've never taken one apart so you know more than me on that one


Good luck and keep us posted as it's all great knowledge to learn. There is precious little information on R32s at this kind of level, so hats off to you mate!

I have two vvt sensors off my old engine, I presume they work it's off of a bub engine. Looks like them in the picture, you can have them if you stand the postage

Wow, thanks ! I am going to strip it down tomorrow to carry out some more investigation, so may give you a shout. Where about are you in the UK ?

Hi Guys,

Just an update, stripped it down again after engine flush oil change, internals of engine is much cleaner, tested the Variable Timing Housing actuators and they are functioning fine, Will be rebuilding the unit again. Have been in touch with RossTech and have the response below: I am going to check:

The oil flow to the VVT unit (by installing the cam adjustor's without the housing and turning the engine over)
Oil pressure using a gauge
Oil pick-up strainer in the sump

Hello,

Thank you for sending us the information. Have you conducted an oil pressure test. This system will need the correct oil pressure and volume to function as designed.

The oil pressure should be:
(As per the repair manual)
- "Minimum oil pressure at 1500 rpm: 1.7 bar."
- "Minimum oil pressure at 2000 rpm: 2.5 bar."

If not reached check the oil pressure relief valve and or the oil pump, if the specifications are met, the oil is most likely being blocked to the adjusters.

The camshaft adjusters are basically the last in line to receive oil supply and the pressure. With out this pressure, the 'Retard Set-point not Reached' fault will occur when the ECM commands the 'Retard Set-point' adjustment to be completed and there is not enough oil pressure to move the adjuster.

Hope this helps.

Update:

Update:

Disassembled the valve timing housing, I found that I had fitted the pilot valve carrier incorrectly. They need to be hard up agaisnt the actuators and peened over. Then pressed into the valve timing housing.

Variable valve timing works fine and checked it with vcds, all I got to do know is check why the hole in the rocker cover is whistling.

Thank you.

Hi CorradoR32

What do you think of this, I was searching online and came across this for the 2.0T FSI engine

Crankcase breather A4 2004-2012,

ImageUploadedByTapatalk1372202545.881103.jpg

So went to Sanburn to see if he had anything similar, found the orange diaphragm inside the breather above (from a BWE engine)

ImageUploadedByTapatalk1372202561.294224.jpg

Its slightly thicker and the spring that came with is is shorter, I was thinking to give it a go with the longer spring from the original 3.2 engine.

(I know I should order the complete cylinder head cover, but I'm being a tight git lol! £160+)

£160! Wow that's gone up a lot!

You could try PMing Lucifer as he's usually got tonnes of bits and might have a MK5 rocker cover.

I would steer clear of the TFSI breathers to be honest as they seem to allow a lot of gunk into the engine, but then again, TFSI's 'breathe' a lot more than the R32 does anyway.

Yes extortion indeed, looking at this:

ImageUploadedByTapatalk1372244003.797253.jpg

It appears that the function of the diaphragm is only to act as a sealing interface, which would mean that the pressure is regulated by the length (stiffness factor) of the spring

Given the above I will give it a go with the orange diaphragm.

(I've bypassed the rads at the moment so don't need to put the front panel on, hence not that much work involved...)

Keep you posted on how it goes ....

(Yes I like to live on the edge lol)
