Thabks for the replys guys Via, from looking at the pics would you say the tensioner is too tight? What do you make of comments regarding steering rack position causing a noise that is common of these cars?

Had the car back with the dealer today and they are contesting this i believe they have filled with a load of hot air blaming the whine as the way the steering rack is mounted in these cars. I am fuming! But trying to keep things as amicable as possible. Had the car took over on my behalf and this is the update they emailed me to brief me on what was done. How they can think this is an acceptable excuse is beyond me. Here goes the reply 'Hi Gavin We have just put your car through workshop and my mechanic has test drove the car – the noise your are hearing is due to the power steering system mounting position of steering rack giving an effect of a whirling noise which is a normal operation of this vehicle. We also checked timing belt tensioner all with parameters and all OK and found no faults in car- but it is always better to get these issues checked out' as regards to there comments that the tensioner is OK here is a photo of it today, they also told me that this tensioner is hydraulically self adjusting and there is no way it can be too tight. Note the black rubber glazing on the roller

It is more closer to 10mm past the notch. When the engine is warm. I am having a independent VAG technician adjust it and hopefully it cures the whine. Do you know if he will be able to adjust it without stripping the front bumper off? Thanks

Can anyone shed any light on the position of the tensioner marker. This is taken after the belt had been fitted and car driven, now i know the marker does move back and fourth slightly when car is running, but should it return to the position it was set to (when set correctly, marks lining up) when the car is turned off. Thanks

Thanks for your reply Magnet, would this have caused any damage to the car do you think? I have been avoiding unneccesary runs and i will have it sorted asap, i have been driving high gears and low rpm ( car basically at idle) to avoid any damage. I would release the tensioner back myself as i know exactly how it is done but i am not sure if the camshaft etc would need pinned at TDC before i would do this as i do not want to upset the timing!

All genuine kit used. Whine is audible at idle only at low revs up to 1500revs when taking off in 1st and 2nd gear . Then a high pitched whine develops when flooring it in 3rd and fourth that i would assume is the pulleys under stress I have already contacted a good idependent with a good rep to adjust it asap as it is clearly not right judging by the markings on the tensioner. His thoughts where that the tensioner looked 'crazy' tight and the pulleys will whine!!!! I hope the adjustment sorts this or the dealer will have one very unhappy customer as they car was 100 percent fine before the belt change.

Thanks Bradley

Anyone?

Said vehicle 😉

Hi i have recently purchased a lovely low mileage 2010 a4 s line tdi 143 , its fantastic however i noticed one issue that i didnt notice during test drive . I am getting a whine when i'm travelling slow in first abd 2nd gear that develops into a turbo like whistle when accelerated . Almost like a supercharger sound. I am now convinced that the timing belt tension is to blame after much research as the garage put a new genuine kit and water pump on as part of the deal, please note this noise was not there when i test drive the car prior to timing belt change. At this stage the garage refuses to see a problem, hiwever i done my own research and renoved the top timing belt inspection cover, it seems clear to me that the tensioner is overtightned as the marks do not line up as i believe they should making me believe the belt is overtightend causing said whine, see pic attached. So my question now is can the tensioner now be put to the correct tension without replacing the whole lot, and also without stripping all the bits that needed removed to fit the whole kit.? Will the belt have stretched? It is a kevlar belt as far as i know. Any experienced audi VAG technicians on here i look forward to your response? Thanks

Did you get this sorted?
