    Hi sorry to open up another thread about this, got a quick few qs.

    Got my 2009 A3 booked in for the balance shaft and hex key to be replaced.

    I just wanted to confirm whether KMB parts is the best place to source this? As my mechanic said he can supply it for £175... The warranty with KMB is 2 years but worse case scenario it did fail, wouldnt it damage other parts as well? If so whats the point of the warranty?

    Is there any other problems with this model? I Just want to do all preventative work and therefore no longer be paranoid :p

    How many hours labour will this be? Thanks.

    As a reference you could contact Mike on here who can source you any OEM Audi parts you need. I've used him a number of times, he provides a good service and saves me from having to visit the dealer myself. You can find him via the Parts Request System on here or message him privately (username: mjr901). You could also contact TPS for OEM parts (they have a number of branches in the UK and specialise in OEM Volkswagen Audi Group parts).

    So you've definitely got the inferoir 77mm hex drive key ?

    From KMB it's £215 on an exchange basis so mechanic is getting a trade discount for it to be £175 .

    As far as I know it does due to it being an 09 plate.

    I dont know if the mechanic is actually getting it from KMB parts so thats why I preferred to get it from them myself. KMB also offer a 2 year warranty but dont know how that works really...

    Again how many hours labour do you reckon it will be?

    Any other work that could be the done with the sump off? What about cleaning injectors?

    Thanks.

    Thanks but this part is sold by KMB parts as Audi charge a grand for the whole module.

    With the sump off, clean or replace the oil strainer.

    Hi soot1 thanks for the suggestion. I have read up on this somewhere but didnt know it affected newer audis, are you reffering to the oil pipe getting blocked up and potentially causing engine damage? I think it would make sense for me to do it as it has been on long life servicing every 18k but I am going to change this to 10k/annual.

    Is it also advisable to clean the sump as well as the strainer? Would an engine flush be enough?

    Might as well do the sump and engine flush whilst your hands are dirty.

    Done the adjusted balance shaft and hex key change, hope its worth it! Cost me around £600 all in including a mini service. Il try to get a picture up showing my old module so people can see what it looks like if they are looking to do it. Mind you, it didnt have too much wear on both the key and the keyway hole.
