- Audi A6 3.0tfsi coldstart
The cranking time is extended due to carbon deposits on the inlet ports and valves and the camchain rattles quite bad!
The car has 280.000km on the clock and according to the service history tensioners has never been charged and and the inlet never been cleaned.
Se my other video where I walnutblast the inlets.
Hello,
Thank you for this video and comments.
I have the same rattle problem on my 2009 A6 V6 TFSI.
I will try to change the 2 top tensioners.
I bought the engine timing tools.
By removing the compressor, is it accessible? Do you need to remove the catalytic converters?
For parts, I saw in another video that you bought INA tensioners? I hesitate to take those at Audi which are very expensive.
the small slides at the top were not broken?
Has the cold start rattle problem ever returned after replacing the tensioners?
Thank you for your answers.
Hi
Thank you for watching my video!
The removal of the compresor is nessecery but it is very easy and tales only about 20min
When it is of then change the oil on the gear!
On my car removeval of the catalyst converters was not needed but I read on Audizine that some S4 and S5 with same engine has a shield for the secundary air valves wich is not possible to remove with the catalyst converters not removed...
The tensioners from INA did the job and there was no cold start rattle afterwards!
The small chain guides you will need to get geniue bud they are only $4 each.
Also you need ti buy new bolts for the tensioners ant the cam spokets!
If you are happy with the car and want to keep it for a long time i would suggest that you chance the valve lifters and rollers.
I didn't and I was struggling with sporadic ignotion fault on one cylinder. It turné out to be the rollers and lifters so I had to do the cam timing twice😂
Mine does the same thing. Was there any damage to the timing components as a result of the chain slap with the old tensioner?
I am actually going to try changing the oil pressure check valves before doing the tensioner to see if there is an improvement.
Good idea with oil pressure test but I don't think you will find it too low.
It is caused by oil draining from the tensioners.
From what I could see there were no damage to other timing components.
@@torbenfunch9937 Thanks!
@torben , he is referring to the valves that keep oil in the heads.
Were you able to replace tensioner on car?
hello friend
Before you replaced did you get any code with a fault number?
Hi
No there was no fault codes regarding the timing.
But I had faultcodes for misfire on one cylinder.
It gave me some headache!
It turned out to be the rocker/rollers for the hydraulic lifters!
If you deside to change the cam tensioners then I would suggest to do the rolers and lifters at the same time. They are not that expensive. You will need new bolts for the cam covers though...
@@torbenfunch9937 thanks man, you change only the tensioners?
i have the same noise and i dont get a any fault code, but i check all the 6 cylinder, and i get 1 misfire counter on the cylinder 2, i think its a same problem :(
@@msika933 yes I only changed the tensioners!
