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
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.
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.
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?
