Been revelling in the reliability of my urS6, and thanking my lucky stars when reading other members posts about engine faults.
Unfortunately my time has come, while accelerating away from pulling out at T junction there was a slight jerk, a bit like when you're walking quickly and one foot slips on a wet leaf.
So drove at the same speed as the rest of the traffic, and found a few minutes later on the motorway that when floored while it tries to do it's best to respond, and rev and produces boost, but not freely, it is like it is getting choked for petrol, as if the pump is starting to fail ? Fuel filter is fresh.
Not sure if this is the way a pump fails, as on my Avant it stopped almost instantly with no warning, and we had to change lane and coast to a halt.
Haven't suffered a boost leak before, so don't know what the symptoms are when one does, can't hear any obvious whoosing sounds, but hard to hear on the motorway, but the car doesn't do any hard cut like a rev limiter.
As I say, at say 4k rpm it's hesitating a bit and is not reving out cleanly and easily to the rev limiter, as it normally does / can do whenever the occassion demands it.
Will eventually show max level of boost, but not as energetic as normal, and I don't feel happy forcing it to perform.
I don't have vag-com.
Any comments or questions appreciated.
Thanks.
