20 tdi tuning

**jkh112** · 04-06-2008,08:12 PM

I have had my 20 tdi s-line on order for a while now, so am looking forward to driving it soon.
One of the things I would like to do is tune the engine. I previously had an older a4 with a remap taking the 140 bhp up to around 170 bhp and was very pleased, but as it was an older car it never went to the audi dealers for servicing.
I am worried that if i get the remap done on the new s-line then an audi dealer may upload a new map at service time and over write it, or worse spot that the car has had a remap and cause problems with the warranty.

Has anyone had any experience of taking a remapped audi to the main dealers for servicing and if so did they notice, or over write the remap?

As long as you notify the dealers deceptionists prior to workshop visit there should be no issue.

The technician has the option to bypass the servers request to carry out a comparison test and you have the right to decline any workshop action campaigns (recalls).

There is already some wac active including egr valve replacement.

As I don't really want the remap to be known by the dealer (company car!) perhaps I would be better off with a tuning box. Anybody got any good or bad experiences with these?

remaps are difficult to detect

I had a tuning box from dragon performance for a good while, it was very effective and did exactly what they claimed except with fuel consumption.

It didnt cause the car to use more fuel and probably improved economy slightly, but the fuel consumption readouts on the dash became inaccurate, giving average of 57 when actually more like 52mpg.

This makes sense considering the way it works by intercepting the fueling signals to the injectors and modifying them so more fuel is being fed into the car than the ECU thinks.

This means that although you may get fuel savings, they are nowhere near those claimed by the manufacturers or as displayed on the dash.

I have since changed to a bluefin from superchips as I didnt like having the obviously visible box under the bonnet. Similar improvements, maybe not so savage at 1800ish when the turbo kicks in but pulls through a little better at higher revs with bluefin, and fuel use readings are accurate.

Ive still got the digital box sitting around somewhere, which i'd be willing to sell for a good price if anyone is interested. I've got the 04 plate 140 bhp golf, so should work with any car with the same engine, although i dont know about the compatibility with audis or newer models.

Hi Dod
Is the tuning box still for sale?

I see they now do a superchip for the 143 but not a bluefin yet

Firstly stick with a PROPER remap even if it's a handhelp device like blufin or a ChippedUK ST3 handset that I can supply. As already said with the add on tuning devices they do intercept the fuel readings and so on which are NOT the proper way of doing things. If you have the proper job then all correct maps within the ECU are altered. It is very difficult for dealers to know if a car has been remapped but if they did detect it and reset the ecu without your knowing, then the company that put the remap on usually will just re-flash again at a nominal charge. It all depends on where you live as what company you want to use. Should you ever have any problems you don't want to be travelling for hours to the company to get things sorted.
