Cheers , Aiden is nearer .

Haven't thought about the thermostat housing , what's the importance of it ? Original breaking or something I guess .

A dealer or TPS item only ?
I've broken two and I'm careful.

The stat gently pushes in and then twists into two very delicate clips in the plastic stat housing.

Fitting the stat without it being secured is very difficult.

Less than a tenner from VW if I recall.


Any idea what part number , Col ?

First 3 were over .

I wouldn't call 0.08 well within :wink:

Still mission accomplished and largely due to a new thermostat .

Yes definitely less diesel particulates to breathe , just as well they don't analyse NOx :wink:

Just to clarify the first 3 blows being over were over the 0.60 VIN , not the slack 3.00 default .

First blow was around 1.75 so technically a fast pass but he knew I wanted to find it's true mean .


Just to throw confusion in the mix one year dad's dpf euro 5 blew nearly 2.00 on the first acceleration requiring more , the end mean result was extremely low .

This year first blow was not much over 1.10 so fast pass with a now gutted dpf & egr off Stage 1.

So the Dpf's aren't the impeccable soot catchers you think .

To blow low everything must be perfect.....
Even some dpf equipped Euro 5 & 6 could struggle to pass their VIN value .

So as it stands concrete evidence to get a lower mean value .

2 Stroke oil and a new thermostat ( obviously do CTS at the same time ) .

My dpf gutted/egr off stage 1 remapped 2012 golf has a vin value of 0.60. I always do a service before my MOT, oil & filter change plus fuel filter, + 2EHN with premium diesel, and a cheeky clean of the tailpipe, but to be fair my tailpipe doesnt have much soot in it. If mine fails this November i guess the worst case scenario is a new dpf. I have already contacted the tuning company who did the work on mine and have said they would turn all the sensors back on in the map for free, but reiterated that i would be fine and wouldn't need to. Only time will tell i guess

2012 dpf equipped 0.60 lol .

The dpf pressure sensors should still be working it's just the remapping adjusts their perameters so a regen is never requested .

Maybe it's easier to generalise to 'off' .

Yeah these vin values are laughable, but if thats what the testers are adhereing to, then people will struggle.

My tester gave me the impression he was going to tick the boxes for not having a vin valve - is it there / is it readable etc so it's back to the default !

He already turns a blind eye to my downpipe .

Yep the dopey population are slowly waking up to the news lol.

Hopefully theyll get the worst offenders before most get wise to it.

Yes itll be unfair on some but thats life. Meanwhile what sneaky tactics are going on with diesel pricing just now!

Hi folks, just seen a comment on a RAC forum from a current MOT tester regarding the new emissions test on diesels,
" as a mot tester v/w audi diesels from 2010 cannot have emission checked as you cant rev them up the dvsa have told us to abort that part of the test and have not told us of any new way of testing them "

How true is the above ?

So nearly month around since changes are in action. Anything new about it? Any fails due to lower smoke test numbers ? Any other things, people having problems with? Or it was more just a panic before, and nothing really changed? My neighbour passed his 55 plate merc e220 with second time, failed on rear tyres and one front sidelight. Smoke test was 0.18, and that car ir far off being perfect, so don't ask me how. It's an automatic transmission, so maybe different limiters at idle, just guessing now.

It was a lot of scaremongers posting cr@p.
The main changes only concern newer cars.
With a b5 or b5.5 they aren't interested in the plate value as they don't come into the new reg's.
