Anyone had their emissions fix reversed?

Following on from an earlier thread asking whether anyone has had their emissions fixed, I was wondering whether anybody has had their fix reversed? And if so, what were your reasons and did the reverse deliver what you had expected?

Hello,

I had mine completed and it made no difference to anything i.e. performance/fuel etc.

I don't see why anyone would have it reversed to be honest

Then you've been very lucky, I suggest you take a look at this facebook pressure group with over 7,000 affected members trying to hold VAG to account for the damage/expense/inconvenience and occasional threats to life that the emmissions fix has caused.

Wow. I also know of people who have not had a problem with the update. It would interesting to know what cars / models and years were effected.

My last Exeo 170 wasn't fixed, I ignored all the letters. My replacement Exeo 170 was fixed before I bought it.

I find they both drove the same but the fixed car regens it's DPF a lot more. When a car regens, diesel ends up in the oil supply. Over time this dilutes the oil and causes the level to rise, which shortens it's service life. If you have a fixed car you should really be changing your oil much more, like every 3000 miles. My fixed car will be rolled back for peace of mind, the place I'm using only charges £60, which is 2 cans of oil.

This is interesting information.

My car was done a a log time ago now, well over a year ago now. Also, my car gets a service every 10k and the oil is in great condition when it is removed, so I don't worry nor am I concerned about it. My car works brilliantly and it is currently at 184k, which stills run like the day I got it at over 100k ago.

Mine had the fix before I bought it and I’ve done around 10k with no issues (touchwood) and monitor it with VAG DPF. It usually regens every 200-300 mile when it gets to 20-22g of soot. It appears the 1.6 TDi VAG engine has suffered issues the most! I know quite a few 2.0 engines have had issues also mainly the EGR valves but to be fair most car manufacturers EGR valves fail at some point. I did look into having my reverted when i first purchased the car but talked myself out because as the old saying goes “if it’s not broken don’t fix it”

Funnily enough, "if it ain't broke, don't fix it" was the reason I didn't get my old car fixed :)

I've read that the fix forces the EGR valve to open further than it was designed for, so they get stuck over time. You can buy copies of the Dieselgeek limiter thing on eBay for a tenner, bolt it onto the EGR and it stops it opening too far. Trouble with the Exeo is a lot of other components have to come off to get access to this (injector pipes & fuel rail among other things) and I can't be bothered with that hassle if the fault code appears after the TBM warranty has expired.

I totally agree with you on the fact that most EGRs fail at some point, however have you seen how much an EGR is for one of these in the current market? They went mad and upped the prices big time! If I can avoid that charge with a much smaller charge, I'll give it a go :)

The 2.0 engines have been lucky, especially compared to the 1.6. My best friend's partners MK6 Golf 2.0 TDI became problematic just as their first child arrived. They couldn't take her home because it refused to start in the hospital car park and VW told them they had to wait a few days before it could be looked at. They couldn't fit the baby, pram, mum and dad in the Mk2 Leon Cupra so it wasn't a fun time for them. It came back with a new EGR and it's been fine since, but to eliminate the risk of having it happen again they've had it rolled back and noticed their MPG has gone up.

Good to hear you're keeping an eye on things with VAG DPF, keep it up as you'll have the upper hand if things start going bad.

I’ve only ever run the Exeo on v power diesel since I’ve owned it and always ran v power on my previous Mini’s and feel it helps keep things tickling a long and keeps the internal parts cleaner. Possibly a placebo but like I say I “touch wood” so far as it runs a dream!

All affected engines across all affected VAG brands have been suffering, sometimes quickly sometimes a year or more later. As mentioned previously the chief culprit is the EGR valve that fails, at one point there was a global shortage as so many were being replaced. Also common fails after having the fix done are the injectors. The issue is so bad thats why VAG introduced the Trust Building Measures to replace certain failed parts for two years after having the fix done (this is because although they wont admit it for legal reasons, the same parts keep failing after the fix for thousands of customers, resulting in very hefty bills putting people off buying VAG altogether). Some dealers still try to wriggle out of this though and charge customers, or dont inform them of the Trust Building Measures. After that two years though you are on your own. Even if parts dont fail, the engine after the fix does work alot harder and the main way this manifests itself is an increase in the frequency of regens, with many reporting they are happening every couple of hundred miles. For me this would be every single day.

I still dont understand why people have had it done, its a big risk to the car for no benefit to the owner/driver. With many drivers having had the fix applied without their permission there is no way my Exeo is going anywhere near the main dealer ever again, unless it becomes a legal requirement. It should be noted that in the US VAG were forced to buy back any affected cars that owners didnt want 'fixed'.

Tom, who is doing a rollback for £60, my 2nd Exeo had the Fix before I bought it, have not noticed any difference to my 1st one though.

Unit18 in Milton Keynes.

Same here, I ignored all the letters for my first Exeo, tried to find a replacement that hadn't been fixed and gave up after 6 months when this high spec one came up. I noticed a difference in MPG and it regenned too often for my liking. I had the rollback done last Friday, MPG is already up and engine sounds more relaxed at idle.

I scanned the new Exeo today (only 64,000 but with the emissions update), EGR insufficient flow fault, I have a 165,000 mile Exeo, same spec but no emissions update and have never seen EGR faults, is it worth taking it in to the dealers for the 2 year warranty on emissions update and then rolling back?

Yeah if I was in your situation I'd do that, in fact the tuner that rolled back my car said I should probably wait until the EGR fails and do the same.

Im glad i never had mine done. Saying that I dont think I've ever seen my dpf regenerating. Ok my exeo has only done 44k and does a mix of short and medium length journeys for the most part. Its never once told me i need to drive at high revs to burn it off.

Had mine done, just so I have the "stamp" in the books. Then immediately took it to a local remapper to get it done properly.

Interesting thread guys. My exeo’s EGR Light started coming on intermittently less than a week after my last service (December)which I thought was weird. The update was done a year and a half ago... I turned down the offer at cost to me to have it checked (at cost to me) at my local dealer and I’m horrified by the cost to replace the component. MOT coming up at the end of the month so a we bit concerned. My exeo is just under 40,000 miles.
Any contacts in the Bromley/Orpington area who could reverse the “update”?
