Hi there,
I've noticed that my 5.5TT has a mild to moderate tendancy to surging when on a constant throttle between about 1600 - 1800rpm. It makes the car feel jerkier and less refined than I'd like.
I also noticed that on at least one occasion swapping from Shell to Tesco Momentum made...
Am looking to purchase a late 2011 E63 5.5TT estate. Want to know what I should look out for on a 4 year old car like this and what to look for in terms of warranty. Will be buying from a dealer but not necessarily MB (although it would be preferable).
Understand the risk of buying something...
Does anyone know if the new AMG engine is a completely new engine built by AMG. Or is it the current 5.5 NA mercedes engine with two turbo chargers added on by AMG?
