Hi,

I recently purchased a used EOS 2011 and in less than a week the DSG mechatronics unit failed.
I test drove and had it checked by a mechanic before purchase and serviced it after purchase.

It is now at a place called mechanic that specialize in DSG repairs. They quoted $3,800 for the mechatronic unit and possibly a further $1,800 for a clutch pack.

The transmission seems to be just fine, no noticeable shuddering, shaking, jerking, no harsh shifting but when the transmission warms up it fails by not going into 4th gear. P,R,N,1,2,3 all still function correctly. Once it cools down everything works just right again.

Should I just bite the bullet? or is a there a cheaper option, will VW australia help in any way? isnt it a known fault?
Does this all seem plausible?
I hope my engine doesn't explode the week after I get it fixed, isnt their also a concern with the timing chain tensioner?
