2.0 TDI 170 Remap

[Ahun7er]

I am looking at getting an economy map on my 170tdi as I will be covering lots of miles and also i've been advised it will eradicate the flat spot I have at low revs.

I just want to know first if there is anything else I will need to do for the remap, assuming the standard clutch can cope with this type of map?

I have read about doing a DPF delete and EGR blank but ideally want to avoid this extra cost, are there any implications if I don't?

Thanks in advance.

Hi, I've been running a remap on my 56 plate 170 for the last 18 months or so. EGR & DPF are still on (and have caused a few issues by themselves-might decat at some point). I don't push it often & never from standing start so clutch has been fine (I was worried about this too). Mine's not an economy remap and has given a lot more punch to the old bus. Basically... go for it.

Don't do anything until the oil pump drive is investigated , engine code ?

You don’t have to do anything with the car, no one put maps that can harm either the gearbox or the engine into your car. That is bad for business! I run a tuning company myself, and I suggest to leave EGR and DPF for now if it’s working like it should.
They also do diagnostics of your car beforehand, and they either fix the fault codes or let you come back to remap after you have had them fixed.

I think the reference was to the known mechanical issues these engines can and do have. Basically make sure all upgraded parts have been fitted before tuning.

Cheers guys.
Mines the BRD engine. I was just wanting to ensure I didn't have to do any mods to accommodate the remap.
Just to make for a better drive and fuel economy.
I've read and been that the flat spot low revs is typical for the 2.0tdi and is rectified with a map. (I'm used to the 1.9pd as my previous golf had which was much more responsive at low revs)

What we are saying is the EGR and DPF as they are functioning fine should be left alone and no mods are needed to accommodate this type of remap?
I suppose I can always give it a go and if there are any issues I can get the map taken off.

With the 170 the turbo is bigger thus takes longer to spool .

BRD is affected by the planned obsolescence 77mm oil pump drive balancer shaft issue .

Modified remanufactured balancer shaft and 100mm hex key kit , if you don't it's just a ticking time bomb .

 

[Ahun7er]

I get this regarding the bigger turbo but I've had bigger diesel turbos before which are much more responsive lower revs.

I'm not certain that the balancer shaft has or hasnt been done by the previous owner as it has been looked after but it's a risk I currently have to take and a bridge I hope I don't have to cross.

So as this question is regarding the remap does it put more strain on the balancer shaft?

 

[Gazwould]

I don't get these people who want to spend money and do modifications and show no interest in rectifying a known major engineering issue which to rectify is a modification !

The remap will put very little to no extra load on the balance shaft but as above yeah it’s expansive to get it replaced but it’s cheaper then replacing the turbo and a engine rebuild when it fails.

Does the 170 have a DPF then?
Mine's a 140 '08 BRE and no DPF (last of the line, so I'm told) and no longer has an EGR either.

Mine's a 56 plate 170 - and yes it has a DPF. I have been told by a few places that it's an early model to have DPF (which would explain why the technology doesn't work very well)

How about the BRE, same oil pump issue?

Didn't you put a link somewhere to a company called KLB or some such that did the oil pump mods?

 

[Gazwould]

Yep BRE has 77mm oil pump drive .

KMB Parts Direct .

 

[AvantMike]

And with awesome timing... here's what a BRD hex key looks like after 88km
@Gazwould should be receiving his commission any day now.
Took my indy 4 1/2 hours to replace hex key & oil pump, parts from KMB

 

[Gazwould]

Just 0.5mm off those 6 edges and the oil pump fails to pump .

They'll all look like that now , serious design fault .
