2006 A4 Avant S-Line Tdi 170 Performance Issues - Please Help!

[Andrew170]

Does it reach normal temp within a reasonable time? I had a faulty thermostat which meant it ran too cold and really dammaged performance and economy! Also if the exhaust doesn't get hot enough the gasses condense and you'll ge todd smells and visible smoke out the back...

I'm two weeks into ownership of my A4 avant, s line 170. It's 35k miles, 2007 and replaced a 2004 golf 140 tdi. So I think I'm a similar case to original thread author.

My initial experience was very similar. The car didn't seem as nippy or responsive as the golf, and mpg is dispointing.

However I've decided the problem is the comparison and not the car. The A4 is clearly higher geared than the golf as at 90mph the golf would be doing 3k rpm in 6th, whereas the audi is running at less than 2.5k rpm in 6th.

The A4 is basically a more comfortable cruising car, and driven as such, rather than like a nippy hatchback I've found the mpg is improving. Also noticed much better performance on a tank of premium shell diesel. Its early days, but now I'm getting use to the car, I becoming happier with the way it drives.

Next question for me is to remap or not??? its another £300 after all!!
