A new member here with the following issue on my Y reg 2001 Vauxhall Astra 1.7 DTI LS 16V ECO4 with 145 K miles:
Smoke during acceleration, especially uphill: Replaced glowplugs recently, regularly serviced with new air filter, oil/ fuel filters etc.
Also at high rpms (aroung 3000) while cruising on motorway (speed of 85 MPH+), the MIL light comes on sometimes (which I think could be related to smoke at high rpm) as I can see smoke through the mirror from the lights of cars behind me. I've a feeling that the turbo has stopped and car is driving like a naturally aspirated diesel at those times...
The acceleration used to be superb in my car buts its slowed a little bit recently but MPG is still very good...
I was thinking to check/ clean EGR valve and then MAF/ MAP sensors.
Any guide on where to find these on Astra and then clean them? None of these have ever been cleaned/ changed on my car.
Thanks for your help in advance..
