Hello,
I am having problems with my car these are symptoms -
vauxhall astra design twinport mk v(5) 2005 1.6 has done 70K miles
Failed on MOT all emissions (See link)
http://postimage.org/image/shio5k08b/
- Running very lean
- ECU putting tons of fuel in because of lean running so its eating tons of fuel
- White intermittent smoke from exhaust only seen myself once
Garage number one says (After MOT fail on emissions) -
The o2 sensor gone and needs a new CAT. (£550)
Garage number two says (After emissions fail and white smoke)
- Needs new engine (Piston rings gone) (£1500)
What I have done
- New sparks
- New air-filter
- Various chemical cleans (RedX, Injector Cleaner, Cataclean)
- Only one error code now cleared and not returned (Running lean)
-Linked to laptop no obvious problems
Possible problem
- the o2 sensor might not be functioning correctly seems to take some times a few seconds to cycle further testing will be done on weekend although this does not explain white smoke.
Points to note
- Car idle perfect
- Car drives fine
- Using lots of fuel
-No signs of blow headgasket
When the car was running I put my hand under exaust fumes and it was so hot it burnt
when the car was blowing white smoke I put my hand in same place and it was just warm air, I could also feel flicks of liquid got a white piece of paper and the liquid was clear like water.
Any suggestions as to what could be causing white smoke.
Originally thought maybe the cat is dead but this would not cause smoke.
Then thought maybe its unburned fuel but this would be black smoke.
