Mine scraped a pass as well after failing first time due to smoke and then after extensive 'Italian tune up' I got a reasonable number. I have a Gus tuned 2.0 JTDM and its got a straight through pipe on it.

If you know what you are looking for it is *extremely* obvious as soon as you pop the bonnet that the DPF is missing on the 2.0. It is right in front of the engine. You would need a lot of cardboard and superglue to 'hide' the missing DPF. Sadly the job was done before my ownership otherwise I would have insisted the DPF stayed on.

In the meantime, I'm on the lookout for a 2.0 DPF as although the car undoubtedly goes very well, the exhaust smells really smoky (although no obvious smoke) for about half an hour until it has warmed up, and even then it has a bit of a BBQ effect - not as clean as other diesel cars I've owned. A new DPF costs 1600 from Alfa which is roughly a quarter of the value of my car (at the moment!). Anyone doing this sort of tuning must be a doing very well from reselling the 'knackered' DPFs on to mugs like me

Vauxhall/GM apparently used the same engine in the Insignia/Astra 2.0 CDTI and OEM DPFs for that are reasonably easy to source and fairly cheap. Here's a pic off ebay. I had a look at an unmolested 2.0 recently, and it does look very similar to my untrained eyes... quite different to the 2.4 and 1.9 DPF.


The problem is getting your hands on a 2.0 DPF from an Alfa so that you can compare with the GM one above and see if it is indeed the same fitment... so if there is anyone with a spare 2.0 DPF they can lend me...or measure up... I promise I won't sell it and go on holiday in the Bahamas

You should find someone who has a 2.0 JTD and wants to remove the DPF, then you can do a straight forward swap and neither need to pay for a part. There's bound to be someone on here who wants to remove the DPF and get a few more BHPs from their engine.

Hi guys!
Is it really necessary to remap (to avoid fault errors on dashboard) a 159 2.4 (200hp) after removing the DPF?
My problem is that I've already a powerbox and I don't want to spend more money on that. If the fault error appears only when it tries to regen, that's no problem because I can delete with FiatEcuScan until the nest regeneration! The real problem is that the fault error stays in the dashboard all the time, like that it would be impossible to escape to the complicated issues in the periodic controls and to be forced to get a new DPF to allow using the car on the roads. Can anyone help and advise me the best way?
Thanks in advance!
