Testing Boost leaks at the dealers.

[dajonic]

It's not the fact they didn't do the work, more the yes we can, no we can't, yes we can and finally again no we can't. When they were presented with the facts ie modded car ( they even asked me to go home(just round the corner) and get the maps from PDT) to be told after picking the car up the next morning that actually no we couldn't touch the car due to the facr it was mapped??

Crazy but what the hey. It's over and done, finished. I'll still buy bits from them, and continue to get it serviced by my own garage. I'll speak to JKM in the mean time and sort out a date.

thanks for evryones comments.

Actually from what I have read here I think Mr PDT should have left your car stock so it could be diagnosed by a main dealer rather than map you and then say you have a boost leak.

Or even book you back in to resolve the problem.

....Good point. Don't most tuners thoroughly check the car as standard before any remapping? I know JKM do and, if relevant, they wouldn't remap until a problem is firstly resolved.

In Daves defence the car was fine during the first set of runs and the car was logged if I remember correctly and nothing flagged up before anything commenced. The boost problem only reared its head after a numerous amount of runs with the new map in place. Time was an issue for further investigation as I had to head back to Bristol from Tyne and Wear for work the next night. Dave did say idealy he'd like to do exactly that. As for taking the map back off well thats power of hind sight stuff maybe.

Its a shame you are not closer really as then this would have been a lot easier.

As for vw not wanting to work on it, thats their decision at the end of the day but their excuse is a bit lame as the map wouldnt affect any logging or diagnostic work in the slightest.

It would have been an option to leave with the car on a standard map but the customer had travelled a long way and had a long drive home, and the problem wasnt evident until late in the day so the map itself is fine, try finding a specialist and i will gladly send both the original and tuned file in an open format to them incase they need to swich between maps.

Or buy a VCDs cable and i will teach you how to datalog and how to look at the data to find the problem, its quite easy with a bit of guidance.

According to this thread http://www.mk5golfgti.co.uk/forum/index.php/topic,19417.0.html Mr Dajonic has a VCDS cable.

Cool. I'll get the VCDS sorted and go from there.

In Daves defence................

....I'm just posting to clarify that I wasn't throwing doubts about PDT - By all reported accounts they appear to be excellent in their approach and attitude.

 2.0 tfsi P0299 fault code

How major is the negative boost deviation?  What is the ecu asking for a what is the turbo giving at what N75 duty and rpm? 
A basic logging session should point you in the right direction.

The Shark dyno plot is from my vehicle and it recentlly made 236bhp on R Techs rollers with 264lbs of torque. The above plot was done at Geoff Bloor Garages in Nottingham. When I had my car in at R Tech it was to have a pressure test and dyno run because I was having a P0299 fault code re-appear. My car had no leaks and appeared to be running fine apart from the fault code coming back.
Yesterday I did some logging with Ben (Shark90) and the turbo was missing the required limit by 500millibars. Which is quite a big gap between requested and actual boost pressure. But I have fixed it today by squirting some sil spray into the N75 valve and that has sorted the problem. No more fault code......yet lol I would presume the figures to be a little higher than 236bhp, as it had a sticky N75 valve when it was done. But I can confirm that the map is smooth and pulls effortlessly.

Hmmm, interesting. ^^^ On the drive home there were no problems at all, just the code that showed up on the rolling road. Thanks for the Link Nick
