Hep me: F I X the VW "Fix"
FYI, long post, thank you ahead for reading it....
Just purchased a 2012 Touareg TDI to replace my 1997 Toyota 4 Runner. The 4 Runner averaged about 19 miles to the gallon that was city and highway driving. I wanted the Touareg because I read it got close to 30 with highway driving and reports were about 26 city/highway. Well, I have had it about 3 weeks and it has averaged about 20-21 mpg city/highway. Not too far off from the 4 runner, not good.
Also, when I test drove these, I tested 2011, 2012, and 2013's models and they all drove differently. One had 98,000 miles on it and it ran like a bat out a hell, so powerful. I drove another with 51,000 and it drove much tamer and shifted really weird. Long story short, these were all TDI's that I test drove (about 6 in all) and they were not across the board equal. I figured it's because of the VW "fix".
I live in a state that does emissions testing for registration: you have to do emissions testing to get registered. So I can't delete anything. I'm considering the Kerma/Malone (stage 2) tune and the TCM tune by yrktreg. I have noticed my vehicle seems to hesitate going from a dead stop to a go. If I cross traffic, I press the gas and it hesitates like two seconds then it kicks in slowly and then after 2,000 RPM it begins to move. Will the ECM and TCM solve this and will these two items restore gas mileage? Any in here who have done both and seen gas mileage improvements?
I don't plan on racing the vehicle and I don't drive it like I stole it. I want to know the power is there, the shifting is there if I need it but I want the gas mileage that VW originally said it had pre "fix"/corruption.
Also, any of you who went Kerma regret it? Did kerma destroy your motor or have you seen no issues? I ask because I called them the other day and they said they have ironed out the bugs from years past and the 2019 tunes are mint. The euro/diesel tuners here over the phone have told me that Kerma gets the most power closest to original pre fix and Malone stage 2 is an improvement but not as noticeable as Kerma. Before I pull the trigger, I figured I ask you all who have gone this route.
