Hello AOC forum users
My car is an Astra H 1.9 CDTI SRi 150 - 3 door, 2007, 60k. I am second owner from new, FSH, maintained well.
I have had the car since April 2010 and, apart from the alternator failing last year, I've had not a single issue with it and have always loved driving it.
Today however, I have noticed that it seems to have very little power at low revs, and the experience of pulling away from junctions/roundabouts is not as "snappy" as it was yesterday... and indeed as it has been for the last few years.
I have always observed that the turbo engaged at 1500 revs and continued to boost till about 3000 RPM.
Now, it seems to engage at about 2250 revs and there is a very noticeable lag.
When the turbo spools up the power feels the same as before, it just takes longer to get to the boost.
It's not so noticeable at main-road speeds, but certainly is in town.
So... what could this be?
Please accept my apologies if there are many threads like this. If I have not looked hard enough then please direct me there instead of directing time and energy toward answering this.
