I spoke to my local dealer to and they are in the dark as to what the full impact will be they told me to just wait for a letter.On the other recall about fire risk I called the customer services and they told me my car wasn't affected.

If you have recently spent good money on a Diesel Mercedes Benz that will fall under this 'software improvement' I would suggest the day before it goes in for service/upgrade have the car tested on a reputable Dyno and do the same the day after. ANY drop in performance would mean that you didn't get what you paid for in the first place.
Ask for your money back as it is no longer the car you purchased.
It might cost you a few quid and a couple of days off work but it could pay off if you end up taking them to court.

W204 Coupe was introduced in 2011, so will be Euro 5 with EGR and DPF. So although I have no direct knowledge from MB, I would expect that as a minimum an EGR remap is likely. The effects on performance may be measurable (though not necessarily at full-load on a dyno as suggested), but aren't likely to be noticeable by most users. It also depends a lot on how much adjustment is needed and where in the map(s) the adjustments are made. They could for example leave the map(s) alone above 90% load, max acceleration would be unaffected.
I wouldn't let this put me off a C-class coupe, they're a really nice car. Our previous car was a 2015 C220d AMG Sport Premium Coupe, liked it a lot. If I was getting another one I'd consider a C250d AMG Sport Premium Plus (more acceleration and panoramic roof).
Just don't get a Fire Opal Red one.
Cheers, think I just got a bit spooked what with this and all the talk of the plans to try to 'phase out' diesels. I'll go and take a look and see how it goes.
Oh I'm sure there are plans to phase out diesels, especially pre Euro 5 in cities. I don't think they'll be banning Euro 5 anytime soon, like before 2020. However by 2025 I think it's quite likely that pre Euro 6 diesels will be banned from major city centres. That could be extended to include all non hybrid/electric vehicles.
This is all speculation on my part.

In the present "diesel averse" climate that prevails at the moment I would hesitate to go down the compression ignition route with any new car to be honest. Remember its not necessarily any actual legislation implemented in the future that's the problem but buyers perception or fear of any future legislation that may determine the market.
Certainly a consideration. Diesel used to be a bit of a no-brainer. These days it has become more of a quandary.

Mines not on pcp once its paid its mine.went that route with honda and got sick of it after the 3rd car.
Ours is ours.
Selling my 2015 VW and ordered a C250d so I've been done over twice now!
Does anyone have any details of the MB "fix"? I was right not to take the VW "fix". You never go first. Let others find the faults first..... I assume that my OM651 based C Class will have the "fix" applied at the factory as its not yet been built and its too soon for the new OM654 roll out.
I'd still like to know the MB fix. I've heard that MB shut off the NOx fix below +6C to protect the engine (EGR or something in the DPF I assume). I fail to see how the fix can magically fix this or they would have fixed it in the development phase of the engine. My GUESS is that all the fix will do is turn off this temperature switch (maybe a little less opening of the EGR) and then play the numbers game on the number of EGR/DPFs that fail. Some they will replace as goodwill - the rest will be put down to wear and tear. I think that VW are playing this game but there is a strong correlation between these new failures and SW "fix". The VW letter very sneakily said that there would be some wear on the transmission!
So again - any info in exactly what the MB fix is would be of great interest.

As already alluded to EGR is used to reduce NOx but increases particulates. If the fix is aimed at reducing NOx then its likely the EGR valve is going to be open more of the time in the new setup. This will probably reduce engine thermal efficiency and hence mileage to an extent.

It's a shame that Dieselman is no longer allowed to post, I suspect that he'd have a little less to say than usual.
Or if they can bill it (i.e dealer labour and component) straight back to the engine / electronics manufacturer (Renault) as normally happens with component failure / issues under warranty

Road Tax & Future congestion charges
I read recently that the government were looking into recovering the road tax lost due to inaccurate data being provided by the manufacturers. If the data had been accurate then the road tax collected would have been much higher - that introduces an interesting dimension as the manufacturer caused it but the individual benefitted from it - years of litigation to decide who pay's ! Can't see it happening.

if that happened people could sue the government for lack of checks on motor mfr's after all it is their fault for allowing them to get away with things plus not punishing the firms too unlike america which has sued them to get them to pull their socks up.

yes, i saw a Watchdog programme where VW owners complained the performance was lacking and lost power for no reason. They also used a viewers car pre fix and the TV programme took it to specialist to measure performance of engine and there was absolutely nothing wrong with the performance. Owner takes it in for the official VW mod, gets it back and problems! TV programme approach VW and they say no known problems
