Re: TDI 130 Alternator problems

Check glowplugs and make sure they're switching off. If the engine is at
operating temp, they shouldn't switch on.

Hello,
I have a Seat Ibiza TDI 130 Sport from '03 which has started to behave a
bit
strangely.
It has a dashboard mounted voltmeter standard from the factory, and from
the
day it was new it always reported 14v with the engine running, no problems
there.
However, in March this year, it started reporting 12V or less when the
engine had just started, and will not reach 14v until the engine reaches
2000rpm almost exactly, everytime. It's like the alternator does not
switch
on until 2000rpm is reached. When the car returns to idle it stays at 14v.

I reported it to the dealer, and they initially thought that the
alternator
needed replacing, which they did, but the problem is still there and now
they're claiming this is normal - although it clearly isn't because the
car
never used to do that.

The alternator has been replaced, a new one is clearly visible, as is the
rear-section of the alternator, which is where I believe the rectifier is?
Any ideas what's causing this problem? The revs required to turn it on are
gradually increasing, and I'm worried it'll leave me stranded one day.

Cheers ~
