I tested a brand new skoda superb diesel today,complianced as a hackney carriage,upon testing the emissions & applying the later 1.50 limit via the sun dga2500 tester,when requested to depress the accelerator the skoda will only rev to 2500rpm even with the clutch pedal depressed,this was not sufficient for the machine to recognize & it repeatedly asked me to accelerate,even at 2500 rpm the machine could not detect any reading,just wonder where we will stand when the vehicle is actually 3 years or older & a mot is required?

Hi kjb, welcome to the forum With regards the latest idea as you mention above, it would have been good if somebody in the powers that be had of thought about this problem when the smoke level is so low that a reading does not register, now although we have an old special notice telling us what to do manually, it would have been better if somebody would have had the common sense to have a manual button function on the smoke machine software function to print a copy of the emissions results, and clearly stating that a measured result was too low to record and therefore has met the minimum criteria, thus printing the necessary details as per the special notice, then everyone who tests the vehicles knows what to do instead of relying on an old special notice, and thus trying to find it without a search facilty , which I advised VOSA about a few years ago

Section 7.4 contains the procedure to be carried out; found on left hand side in the INFORMATION column under low emission diesel

Some low emission diesel engines (mainly Euro IV) and those which will not reach maximum revs (due to design features) may fail to trigger a reading due to the very low levels of smoke produced.
If the DSM does not register a reading or shows an error, the printout should be marked accordingly showing that the emissions limits were tested and met but the DSM could not register the reading.
If the DSM will not produce a printout then the tester must make a written note of the following: -
. Test Station number
. Testers name
. Date & time
. Test number
. Vehicle Type
. Vehicle VRN
. That the vehicle passed the emissions test
. No print out was produced due to low emissions.
This information must be recorded and kept with the emissions records for audit purposes for 3 months.
SEEMS BLOODY LONG WINDED,SURELY THEY CAN DO SOMETHING WITH THE EMISSIONS TESTER? IN THE FUTURE

In regards to the software of the dsm needing changing..this subject was brought up at a seminar this week,and it was said that due to the cost involved to the vts in changing the software ,,,at this moment in time and foreseeable future there will be no requirement to do so. Times are hard

Rattle off a few copies similar to the above, leave them by the smoke meter and fill 'em in as necc. Simple, and cheaper than chips (or any equipment mod's/change)

You have to keep petrol emmission printouts on site for three months but there is no requirement to keep diesel ones. I've always wondered why we have to make a note if they don't trust us enough to believe that the emissions we that low that a printout couldn't be had, that we don't have to keep anyway.

Think you might be getting your drinks mixed a bit. If i'm right, there's no requirement to give the customer a DERV smoke test print out.
