Default MPG after belt + change.

A4 2.4 SE V6 '97

I had ALL the cam belt related parts changed a few months back, including
water pump, now and have noticed a drop in MPG. She's gone from 31 to
29..............would this be expected.

Must be something else like tire pressure or outside temperature or
whatever.

If the mechanic changing it got the timing wrong it could do- if for
example the valvegear was out by one tooth it would be enough to affect
performance but might not damage the engine.

That thought crossed my mind after I posted my earlier, frivolous, reply.
But even one tooth would cause a huge loss of power/performance, wouldn't
it?

Juan, is performance otherwise unaffected?

no, performance is much the same, if anything a little better. This made me
think it adjusted the timing a little................so if that's the case
then it would consume a little more fuel. This with the added thought that
everything is tight and may require more power. The job was carried out by a
very competent garage..........I made sure about that.

How do you notice something like that?

My mpg varies wildly on a weekly basis.

the digital onboard computer tells me and cos I got a policy..........keep
the revs between 1500-2500 on average.......55/60mph. I also use minor B
roads most of the time.

Mine tells me too (in my 'budget' A4.....), but I don't really pay much
notice of it. Last tank was 26.9mpg, but I've seen as much as 35.5mpg.

I certainly couldn't see a pattern in it.
