Hi all

Right, my astra 1.7cdti, had a problem with hunting/ rough idling cold so replaced the SCV and has stopped it, thing now is randomly it will idle rough when you stop, ie of a motor way up to traffic lights and run rough fora few min then settle.

It's done it once this morning when i got to the shops and it did it there as I parked, run rough and then settled.*

Not sure what it could be, thought the EGR valve maybe.

Any ideas welcome.

cheers simon

Hi guys, all of a sudden I've noticed my fuel range dropping a lot.
For instance, yesterday it said 480 miles drove 30 mile now says 425 and I'm driving sensibly.
Noticed first gear seems sluggish with hesitation then bouncing but other gears work fine.
Wondering if egr is blocked.
I've cleaned it on my old vecci which was easy also cleaned the inlet manifold and eventually cleaned the swirl flaps.
Egr easy to do on the 1.7cdti? Anything else I can try?

So when my car had Turbo issue's the dealership did a software update to the ECU.

This update is related to the DPF 

Quote:It adjusts the parameters for the dpf temperature sensors to improve dpf performance and avoid overloading dpf, eml lights and in worst cases engine stalling.

it's a software weakness that only effects astra j, cascada and zafira tourers up to model year MY13.5. The update will just adjust the software weakness that is present.

At first I didn't notice
