I've owned a 99 model AGU car and my current 2002(03my) AUM car. VW may claim 150bhp for both cars but the current one is noticable quicker; turbo spools quicker and car feels much more eager to accelerate. I agree with GaryM; go for an AUM car. NDBW cars have a cable throttle whereas DBW have an electronic throttle; makes throttle response sharper.
Early 2000 and earlier had cloth Recaros as standard as opposed to VW's version of that. Much nicer. Also, the AGU engines (I think) are less prone to coil pack failure. Apparently much better for fitting a dump valve too, if thats your desire.
That said, the later ones are VVT and DBW and ultimately more tuneable.
Again, that said... Mines an AGU, its chipped and its BLOODY QUICK!
Never knew the difference in engine codes till now, thanks for the advice. Just checked my engine code and its an AUM, Registered March 01'.
i know someone with a 1999 1.8t and the main difference is he has more Turbo lag, his kicks in around 3k rpm, mine kicks in at 2k rpm, quite a difference there !! So would recommend going for the AUM version definetely....
didnt realise there would have been such a difference with turbo lag! That kinda helps me make up my mind with the other post by myself below (which one do i buy????). I have the choice of a 2000 or a 2001. The 2001 is a AUM, looks like i'll go for that one then!
?12.5K should be enough for even an 2003my car with money to spare. These are cars built from May 2002 onwards and had climate(and ESP) as standard. I just paid a VW dealer ?11800 for my Sept 2002 29K mile car; a 5DR black 1.8T(150) with climate/ESP/cruise/winter pack. Definitely buy a car with VVT; you'll notice the difference even without chipping the car.
Agree with Matt.... there is a definate definate difference between the earlier AGU's and the later drive-by-wire cars.... so much more eager and responsive.
If you're gonna chip i'd recommend the 150 (AUM). .if not definately go for the 180 (AUQ)... thats what i have in my Cupra and you simply wouldnt believe the difference between this and my old AGU 1.8T GTI.
Union jack is right ref. turbo; you should feel it from 2000rpm. Cars obviously vary but my AGU model seemed quite lethargic when pulling away from stationary(very little wheelspin even in wet) whereas current AUM car much keener to go from stationary and quite difficult to stop any wheelspin(I sense new front tyres on the way soon). The Recaros were actually standard upto May 2001 when the 2002my cars were introduced.
