NCT Diesel Waiver

Pimp Ninja

I don't know much about cars, so please bear with me here.

The family car is a 2006 model Ford Focus 1.8 Diesel 190,000KM approx.
It mostly gets used to drive a 10 min round trip to drop the kids to school 5 days a week and occasionally on weekends makes a trip to the supermarket or down "the country" to see family.

Back in April, it went for its NCT and passed, about a week afterwards it started to loose power. Initially it was almost un-noticeable but gradually got worse.
We couldn't afford the repair at the time so kept the car off the road and the kids were walked to school.

The behaviour of the car was during very easy acceleration it seemed to drive as expected, but anything remotely normal or "harder" acceleration the power was not there and there was a whooshing noise of escaping air from the engine.

On examination I found that a pipe (I now know to be called the turbo pipe) which comes from the top of the engine and runs down the left hand side of it was split, and when any pressure built up in it (like when accelerating) the split opened and that was the cause of the noise and loss of power.
Its been repaired now, after being off the road for just over a month.

When I spoke with the mechanic who fixed this (trusted family mechanic) he suggested that things like this can be seen as a result of the NCT test and the emissions test on diesel cars because they are revved so high.

Now I'm pretty sure (since i signed the waiver) that I have no come back.

What are my grounds for refusing to sign the waiver in 2015, or are there any further suggestions that anyone can make so I can follow it up?

If the pipe had been in good condition then no amount of revving would have caused it to split. This isn't the NCTs fault, the pipe was just old.

Theres 190k on it, pipes are bound to wear over time.

If you dont sign the waiver you wont get an NCT.

These turbo pipes on Ford tdci engines seem very soft, had a transit connect '07 and in 165k kms replaced 5 of these. Nothing to do with the way they are driven. Van was off road for 4 weeks may '12 as these pipes couldn't be got such was the demand for replacements (and they were not cheap) in this country.
So nothing got to do with the poor old NCT being to blame and all to do with manufacturers making parts as minimal as possible and once it lasts past warranty period, another cash cow to up their profits......

That pipe is very prone to splitting, they really are of poor quality. Had to replace it on my old Volvo S40 with the same engine.
