VW emissions recall, anyone had it?

During active regen, the excessive extra exhaust heat will, in part, transfer back into the engine block, and thus into the engine coolant.
Therefore the engine coolant will be higher than normal, and if you stop your journey before the active regen is complete, or too soon after it has completed and the exhaust and engine have not returned to normal temperature range, then the the ECU will sense the extra temperature and leave the coolant fans running on the radiator, and also usually runs a small coolant pump to keep the coolant circulating through the radiator until it is back down to normal operating temperature range.
This is all perfectly normal part of an active regen cycle.
Hazards being on is likely nothing to do with it - most workshops require you to drive into them with hazards on so that it's clear you're there - certainly every decent workshop I've been in.
Point is, just because the fan is on, doesn't necessary mean a regen has taken place.
Frequency of regen really depends on how the car is driven, but under normal driving the driver shouldn't be able to notice anything different.
I honestly believe that a large part of the reported increases in engine faults post recall was actually down to the lifting of the 'German engineering' placebo effect. We have had people with EGR failures, DPF blockages, oil pump failures, turbo failures and DMF harshness issues all under the impression that these are new faults that never would have happened before.
Sorry, no. These are all very very common faults that the VAG range has suffered from for over a decade. Especially those damn EGR's.

It also happens when the car has done a dpf regen. My friends dpf failed a couple of years ago whilst we were on a trip back from France and the fans kept staying on as it was trying to regenerate. My coolant temp gauge was dead in the middle (i know it's "dampened" so doesn't move) and the oil temperature was down at 92C and it was about 3.5C outside so I highly doubt the coolant was that hot.
I agree with the accountant the hazard flashers are 21watt bulbs x 4. 84watts total. without a stable power source to compensate for this pulsating load. he said in his post (the hazards were flashing the whole time the ecu flashing was taking place).
i had a luncheon meeting today with a local remapping specialist hoping to get a group buy deal for all of the affected owners that i hold contact details for. i showed him a copy of "the accountants" comment regarding hazard lights flashing during a remap. he was horified, he said that this sort of variation in voltage can in most modern ECU's cause eproms to go into lockdown. so the accountant could have found something quite useful to our case...
Finally had a call today regarding my wife's Leon to say the fix was ready. I said I wanted to wait until I'd got some real world reports about the impact to performance / fuel economy (it's a 1.6 so requires more than just a software update). Next service probably due around June time so will likely wait until then, if at all.

not sure if this helps you make your decision found this on another forum 1drv.ms/b/s!AvcWk_HHJ7e2lSKCPGtHBV19b90L shows performance before and after the recall / fix.
I would have thought hitting the emissions limits would be a problem higher up in the rpm range, not lower down?
Seems bizarre that the change is happening lower down?
So we get a tad bit more in the higher end of the rev range and lose a tad in the lower part.
No biggie = my car wheel spins like crazy in the lower range anyhow lol (175ps)
Still not letting them do it to my car! Are we going to be forced to do it? Will it have any impact on resale value?
Heard UK users are taking VW to court soon - hope we get the same level of compo as our american counterparts

I wouldn't personally call a 32% to 40% loss of torque and a 15% to 20% drop in power between 0 and 2,000 rpm a 'tad'. What's the rev range diesels tend to drive in, again?...
Indeed, in practical driving terms, you have just traded your 2.0TDI in for a 1.2.
I would expect this to be almost undrivable, certainly very disappointing.
Any owner who had dropped that off for the fix and then gone back to drive it home would assume that it was broken. Indeed, he would probably stall it a couple of times before getting used to the new torque curve (or lack thereof)
I question the validity of that graph. The driveability of my A4 didn't change, and that much of a tail-off in torque would have been instantly noticable.
Again, we get "figures" but no source or citation from "the accountant".

Quite - EVERYBODY would notice the difference if the figures were as low as they are in that diagram! - am still not risking it though lol
Will wait for more feedback before I allow them to do this.
Knowing me, I'll have sold the car before I get round to letting em do it - already fancy me a Volvo S90....
Theres defo something not right about that diagram - it comes up in chinese first then translates to english! - err woot!
I did a bit of further digging and found a big thread on honestjohn with numerous people complaining about a sudden massive/dangerous loss of power at low revs and lots of EGR valve issues / repairs needed. Going to refuse to have it done until such time as there is clear incentive to do so: http://www.honestjohn.co.uk/news/vo...guans-losing-power-after-ea189-emissions-fix/
Article is about Tiguan but in the comments lots of people have mentioned their experiences across other marques / makes / engines.
The irony is with the legal challenge being mounted this month, I think there is arguably more of a case to answer on the impact of the fix, than the actual defeat device given the less stringent regulations in EU compared to the US. I am really surprised that nothing in the media is talking about the devastating impact this fix is having on some VAG cars, now admittedly of the large number of cars the percentage of people voicing concerns online isn't that high, but it isn't just the odd one or two people, there is literally dozens and dozens of people reporting similar issues (as comments on a four month old article on a single website). I don't feel entitled to compensation as it stands, but if I had the fix done and experienced problems, I might do.
