2.0TDi Remap?

[A3TD1]

Hello all,

Ok so me and a good mate of mine have identical 2006 A3 S Line 2.0TDi 140 automatic motors with paddle shift, 3dr. He had his remapped and subsequently the car went through 3 turbos and a 4th one was fitted after the remap was removed and the car has been a1 ok since the remap was removed.

I have been wanting to have my car remapped for a while now but have been really off put by my mates experience. He was lucky that he was financially able to just blow money having his car fixed each time it broke, I will not be so lucky.

I've been kinda put off remaps after seeing him go through so much bother so I wondered is that the norm or was his a one off experience?

I have spoke to a few remap people who say they simply will refuse to remap the 2.0tdi since it has "so many problems" whereas the 1.9tdi is "a solid engine".

Shall I leave it alone at 140 or shall I go for a remap? whats the consensus?

Sorry - don't know the answer mate but what I do know is that there are a hell of a lot of threads on another forum about that very question.

The answer is very simple, the person who remapped the 2.0TDI hasn't a clue what they are doing full stop.

Yes the 1.9TDI turbos are much stronger than the 2.0TDI and many tuners are stuck with thinking they can tune the 2.0TDI just the same as the 1.9TDIs

Its 100% important to tune the 2.0TDI correctly and also adjust the vgt pilot control maps that control the position of the turbo vanes.

So its not a case of just flashing in a tuned file that these tuners get via email, you really need to tune these to match the vehicle.

I've seen some shocking tuned 2.0TDIs over the years by some of the so called best tuners out there.

Why they are having problems with turbos blowing is that the turbo is spiking (over spinning) this happens when doing a few things, injecting to much fuel early on, requestion to much boost pressure & not controlling the turbo correctly, So basically not tuning correctly.

So anyone having a 2.0TDI tuned please please make sure the tuner datalogs blocks 011 with vcds on either the rolling road or out driving. Then look at the logs and anything over 2600 actual turbo pressure you will have problems.

I'll dig some logs out when I have time and show a correctly tuned and control turbo and then a out of control turbo.

The 1.9TDI could cope with poor remaps but not the 2.0TDI, this is why many won't tune them.

I've tuned 100's with not one single turbo gone.. (Touch Wood)

Wow, most of that tech stuff went over my head straight away however if and when I come to tune my car I will definitely keep you in mind, sounds like you know what you're doing!

I won't name where my mate had his car remapped but maybe if I say it's a large place in Manchester and they claim to be "awesome" you'll know where I mean? That's not to slander them though they did give very good service and gave a full refund after removing the map and returning the car to standard...

Where abouts are you based?

[PendlePerforman]

We are based in Lancashire, also we are about to sponsor this forum and give technical info where needed.

I've known bigger companies than the one you mention blow many of these VAG 2.0TDI turbos up.

I'll do a write up about logging these so anyone with Vag-Com can check there turbo themselves before or after tuning.

Hi Martin

I have a 170 2.0 TDI. I've been thinking of having it remapped for a while but have read a few negative posts which has put me off. You come across as knowing what you are doing, I have some questions for you.

Currently I find my car a little slow of the mark but when it gets going, it is fine. Will a remap fix this? What sort of bhp can I expect and 0-60 time? Can i expect better mpg?

I usually have to clear the dpf out every 2 weeks or so - I do mainly short drips during the week. Will remapping increase/decrease the frequency?

Once the remap is in place, can I take the car to any audi dealer for a service? There's no chance that they can bugger things up?

How much does the remap cost, how long does it take? Can I drive the car up and get it done on the same day?

Sorry for all these questions.

Dave.

Dave,

I really shouldn't be giving this info as yet as I haven't fully sponsored the forum so I'll keep things short.

The 170hp 2.0TDI has a much stronger turbo than its 140hp model so there isn't as many problems there, with it being the dpf model we cannot tune it as well as the non dpf model so you are looking at around 200bhp which will be a smooth (safe) remap and power will come in earlier within the rev range.

The best option you really have is to have the dpf removed and also tuned, this will release a massive restriction within the system and also no more regen every few hundred miles.

The standard remap can be done at our workshop within a couple of hours, the dpf and remap needs 5hours.

For more tech info throw us an email over. Use google to search

Hope this helps

Due to unforseen circumstances it appears I may have to sell my car however I will buy another A3 as soon as possible cos I love it! Do the newer (after 58 plate facelift) have stronger turbos or are they still cack in the 140 variant?

Sorry for the late reply, Yep the later 2.0TDI have improved turbos it was the 2005 / 2006 models. But still make sure you get it tuned correctly and the tuner must log with vcds and set it up.

No worries Martin hopefully it'll be you if you're still in this business at that time! Do you have a workshop or somewhere you can do the full DPF removal replacement with pipe then do the whole remap shbang and test it all etc?
