dingov70: Thanks for coming back.
The test is taken in Spain. The only difference is I take the car through under the instruction of the tester (same as HGV in the UK). The tester sits in the car to do the emissions part of the test.
I watch the screen for results. The idle speed is fine. At the 3000rpm test, the figures constantly fluctuate (just like the primary lambda sensor does) but as I said, this was on petrol. Im not sure what my rights are to insist on LPG test. IF the petrol lambda sensor is wonky (lazy as they can get) then the LPG lambda sensor (which is the one on the down pipe I assume) is different to the other two.
Although I was not exuberant driving the 45km to the test centre I did run the engine for at least 15 mins prior to going in for test. The engine should have been at working temp. HOWEVER, there was moisture coming out of the tailpipe (it was a cold day).
It's the fluctuation that confuses me...and the tester!
Ive been lucky, just like many others, there are NO tests at the moment...but not for ever! It failed at the beginning of March!
