Astra 1.9 CDTI Engine Trouble / Reply

Just wondered if any of you could shed any light on where I stand concering this issue:

The car is a 05 1.9 CDTI Astra Design - 30K

On the 8th September the car developed a fault which was as follows:
The engine lost power and went it to a limp mode meaning loss of turbo and acceleration, the engine management light came on.
After stopping and restarting the car the engine management light went out and was replaced with the emission light.
Later that week the car was taken to Vauxhall.
They identified the issue as an issue with the inlet manifold and sensors, but as the parts went not available the work could not be carried out. The error code was reset and price reduction was discussed with Vauxhall.
The car was booked on the 18th September to have the parts replaced, Vauxhall had agreed to 40% discount on parts and labour. During the time I had the car no further problems occur, the car drove normally and not lights or engine problems happened.
A bill of £417.07 (£583.90 inc Vauxhall) was paid on the understanding that the issue had been fixed.
The items replaced was the intake manifold, control valve, pipes, gasket and nuts.
On the 11th of November the fault occurred again in the circumstances, the engine lost power and went it to a limp mode meaning loss of turbo and acceleration, the engine management light came on. Once again after stopping and restarting the car the engine management light went out and was replaced with the emission light - the EXACT SAME PROBLEM.

Astra 1.9 CDTi Engine Trouble.

I too today have experienced the same problem on the way to work in this blizzard conditions and for the whole of the 1 Hours journey experienced loss of power and a permanent Management Warning lamp on. When I reached my destination and parked up, I restarted my engine and the lamp extinguished and after repeated attempts was unable to create the problem and in fact when drove home the car ran perfectly.

I have booked it in to a Vauxhall dealer tomorrow for them to run the diagnostics (£77 cost to me for a start). I think it's my fuel filter at fault myself but I'm no expert. If I were you I would take the your car back to the dealer and pester them to sort it at there expense now as they have claimed to it have fixed previously.
If I get it sorted, I will post the details.

My car is 2005 - 56k

Finally got my car back today and the problem appears to have been rectified by my Vauxhall Dealer. My O2 sensor was faulty and replaced at a cost of £139.
They also cleaned the EGR valve.
The car does seem to be back to performing again. However, this is early days yet but it looks promising.

O2 sensor on a diesel???

Yep! That's what the invoice says, the Vauxhall Staff call it and what the error report described it as from the diagnostics readout at two seperate dealers and what we engineers call it.

Once more, whatever the part is called, my car works now OK.

I think Bob knows what an oxygen sensor is, he was questioning the facts. You find oxygen sensors on petrol cars.
