2014 Touareg TDI Fix Reports

I am about to schedule the fix for my 2014 RLine TDI Touareg. Anyone had it done and if so what has been the results. Fuel economy is a concern but mostly performance. Any feedback will be appreciated.

Here lemme stir the pot.... my estimate you will lose 10% (minimum) meaning burning more fuel. There will be a significant felt loss of performance too and am thinking towing anything substantial will suck, oh and youíll burn more AdBlue too. Now the good news is you can (once VW fix is done), redo the fix back to better than stock and turn off the AdBlue as well as delete the DPF and SCR.

Above is based on ďVW fixĒ for 2015 Jetta TDi that is currently being sent back as itís now undesirable. And what Iíve done with our 2012 Touareg TDi, which has made it most enjoyable to drive.

Good luck hope Iím wrong...

wow, that was helpful.


I have had it done on my 13 touareg, vs just guessing what will happen based on a different engine.

Total power feels similar, but the throttle response is totally different. WAY more throttle required in the midrange to get the vehicle to move, which makes it feel like it has way less torque for everyday driving. It is painfully slow to build boost/power after taking a sharp rolling right hand turn onto a different road, for instance.

Basically, now, the driving dynamics suck balls, even if total power is the same.

Less tendency to downshift while decelerating.

Fuel economy seems down, but I havenít gone through a whole tank to calculate for sure. Iím also aware fuel economy may increase somewhat (as compared to immediately after the fix.. not before) as adaptive values within the ECU are learned. Anyone reporting less mileage via the MFI readout should be ignored.. we donít know whether that reporting is accurate post fix. Calculations based on fuel pumped vs miles driven is the only thing that can be trusted.

Iíll likely be getting a Malone tune soon, most likely stage 1 as I plan to keep this vehicle for a long time and want to reduce turbocharger wear.

Jus’ so you know.... stir the pot... means in jest, joking, a hint of sarcasm...

Interesting that you have actually done the “fix” yet have nothing to really add.... aside from less felt performance and no fuel loss numbers to substantiate.... too funny. If you actually read what I said, even though it’s a different TDi platform the results of VW factory “Fix” are not surprisingly different... driving dynamics suck balls (as you put it) and I’ve returned Jetta for same reason.

Our Touareg engine platforms are different, (12 versus 13/14) There are significant gains from Malone tuning. MY 13/14 respond even better than the MY 12. I’ve completed Malone Stage 2, Rawtek Exhaust with AdBlue, DPF and SCR deletes and can say, there is a significant increase in felt performance, off idle to WFO. Fuel usage is about the same, (stock versus noted mods), and would increase I’m thinking but it’s challenging to curb the wife’s right foot, she loves the extra performance and it’s her rig.

Not sure I understand your logic as it pertains to “turbo wear”?

To the OP, recommend Malone Stage 2 along with above noted mods you will be pleased with results.

Cheers,

Are you compelled by local legislation to get it done?

Or is it a moral choice?

If not either, why have it done at all?

VW Touareg models are as follows:
Generation 1: T1 is model 7LA & facelift T2 is model 7L6
Generation 2: T3 is model 7P5 & facelift T4 is model 7P6
Generation 3: T5 is model CR7 [Not available in "VW Atlas" North America!]

Personally if I asked the question OP did I wouldn't be looking for sarcasm or how other cars performed, but that's me.

And yes, a "turbo" can/will "wear" out, specifically the bearings and seals. The primary way tuning makes more power on turbo vehicles is to increase boost which allows increasing fuel.. more boost means more RPMs of the compressor/turbine wheels and shaft, (almost always to less-desirable parts of the compressor maps of those turbos,) wearing out the parts I mentioned more quickly. Removal of the DPF and to a lesser extent SCR will lower operating temps which will offset this wear to a small extent but during the times you are actually pushing the vehicle (high boost) the turbo is working a LOT harder and there is no way around it.. this leads to increased "turbo wear". One potential advantage to a DPF/SCR delete is no chance of shutting the car off during a regen, but this is easy enough to avoid without a delete if you are paying attention.

Edit: that said, most people are happy with their malone tunes, IMO it is best to understand that there are tradeoffs. For me, and the reasons stated above, stage 1 is the sweet spot.
