Talk about making a mountain out of a molehill. Just get reflashed. The tuners should do this for free when a TSB or recall is involved.
Oh, please do, for I've had nothing happen with my car since I drove it off the lot. Although I have a super tech, who is the only person I allow to touch the car at the new Norm Reeves dealership in orange county, this ECU modification/update does have me concerned.Whisper said:Just had the update done today on my 2010 Jetta (121.5K miles). Within 100 miles, the check engine light flagged....................
......Will report back with what flagged and why, once I know.
Can you let me know the name of your guy over there? I actually live in North OC and, while I like my (non-dealership) mechanic a lot, I want another opinion on pretty much everything now.Oh, please do, for I've had nothing happen with my car since I drove it off the lot.

.........Hi 'nomad,Hello everyone, I had this update done on 4-25 on my 2010 sportwagen. I have driven about 1000 miles since and I can say it's definitively an improvement.
Cheers!
I don't know. The letter from VW says Calif. will deny registration.......Yes. The letter is making the rounds. There's 3 or 4 threads going on this board alone.
Californian's are SOL - they need to have the ECU flashed, get a signed confirmation and the workorder from the dealer saying it was done before California will register (or re-register) the car. Could get very interesting for anyone who've made mods to the ECU or the DPF/EGR/Cat/Muffler/Turbo. Other CARB states may also have a registration block if it isn't done.
.........Hi 'nomad,
Has your MPG remained unchanged (or has it gone up)?
TIA,

Roger unchanged............Hey ez, sorry for not including such an important detail, but mpg is unchanged.
Cheers!
Hello everyone, I had this update done on 4-25 on my 2010 sportwagen. I have driven about 1000 miles since and I can say it's definitively an improvement. My work order states
Recall
23602599 install updated glow plugs/perform software update
I don't know that the glow plugs are an issue with this engine, especially since we had a brutally cold winter this year and the car never failed to start.
The engine felt funny at times the first few hundred miles. Regen seem more frequent and feel like an A/C clutch cycling on and off instead of periods of less responsiveness. If it wasn't for the pesky P0401 CEL since my second oil change, this car would get best car ever.
Cheers!
Quick update on this thread.P0401 EGR insufficient flow is usually a cracked DPF substrate.
Here's the break down - the EGR filter is for one EGR circuit and is feed exhaust after the DPF. Therefore it should always be virtually clean. Something causes the substrate to fracture (too hot during regen, shocked by sudden temp change, etc?). Now soot is able to bypass the substrate, BUT the DPF is neither plugged nor failing to reach appropriate temp differential so ECM fails to see a bad DPF. Soot now collects in the EGR filter, causing a restriction, as seen by the pressure sensor (on timing cover?). Restricted filter causes a EGR flow insufficient DTC.
You could replace just the EGR filter, but it will plug again. Easy check - there should not be any soot in the exhaust tips. Nor in the exhaust fitting when you remove the EGR filter.
Any faults that affect air flow or its control and measurement will play havoc with DPF life. But I suspect that the update MAYBE in response to some operating conditions that are resulting in damaged DPFs. Also maybe proactive in preventing the turbo damage happening to Passats. Just a hunch.

2010 JSW here too. Wonder about this. ^Hmmm... Wondering why your car has a recall for glow plugs, while mine (2010 Jetta) I haven't heard a thing. Time to call the dealer?
That's fantastic MPG for 2013 Beetle TDI. I've been averaging about 44 MPG.Did the update on my wife's Beetle a little over a week ago and it seems MPG is up a couple points. First trip from Florida to Maine was 51 on the high side. This last trip to Fenway was 53.5 so seems a little improvement. I've been driving it 53 miles to work and average about 55-56 mpg.

MPG has been roughly the same as before the update.Any updates as to CEL's, MPG and drivability? I'll be scheduling the fuel neck tsb HPFP warranty extension service soon, and am still wondering about the ecm update.
My drivability is worse. Under light throttle (e.g. flat road, 45mph in 5th), it feels like the car is cutting fuel for a split second. Roughly the same as if I suddenly pulled my foot off the gas pedal. I haven't noticed it at freeway speeds or while accelerating.Any updates as to CEL's, MPG and drivability?

Is the light throttle issue when the car isn't fully heated up? Like when the temp gauge is between "cold" and "normal" (12o'clock)?My drivability is worse.

I can't speak to fuel mileage since I had new tires put on not too long before the flash. It seems like I'm getting fewer active regens, so I imagine that might help.
Good question. I'll have to pay attention and get back to you.Is the light throttle issue when the car isn't fully heated up? Like when the temp gauge is between "cold" and "normal" (12o'clock)?
