I drive a 2010 plate, A3 2.0tdi 170bhp CBBB engine. I have owned it since new, always used 5W/30 507 spec.
It has REVO remap to 205bhp. Same engine, turbo, clutch etc. Just hit 220,000 miles!
Just don't drive it within an inch of its life, no need, has loads of power!
Don't remap it to death, never thrash it when cold, you know the score.
No problems.
But, I'm a bit of a ****** for oil changes!!
I do it every 5000 to 8000 miles, I don't do the 10,000 or 20,000 mile thing that VAG say.
In fact, I'm changing it again in the morning, after only 5000 miles.
For the cost of oil, compared to the car I love, I think its worth every penny!!!
(don't tell the wife lol)
