Well, it seems that despite the dealers best efforts to rectify the inconsistent running of my '03 2.0FSI they still haven't sorted things, and are now putting together a proposal to replace the vehicle. Finally. I'm guessing they'll come up with a few options for me, so I'd like some advice on which engine to choose.... Having had a wide variety of courtesy cars mostly with diesel engines, and having had so much trouble with my FSI, I wonder if switching to a diesel engine would yield any more reliability...? [The FSI had 2 fuel pumps, an OX sensor, a throttle position sensor, new spark plugs, a re-programmed ECU and finally an EGR valve] Looking at a 'no cost' replacement, the options are likely (hopefully) to still be on an '03 plate, so I guess I'm looking at potentially a 1.9TDI (130 would be nice). I could always stick with petrol - so would a 1.8T be an more reliable than the 2.0FSI? They had coil pack problems did they not? My relationship with my first Audi hasn't started well, but I still really like the A4 Avant, and the dealer can't be faulted through all this (although I'll wait and see what their proposal actually is). I'd just like to make an informed choice when they present me with my options. So, is one variant more reliable than another? If I was starting from scratch, I'd probably go 1.9TDI (130) Sport to balance the performance and economy - and hopefully improve reliability. I quite liked the 2.0TDI (170) that I had for a few weeks, but the 2.0TFSI was very nice too..... Confused.
