After reading this thread and one or two others on other forums, I decided to give
blacksmoke.co.uk a go.
I got this lead
(UK) MPPS V13 Remapping Tool OBD DL16 Chiptuning Flasher Remap EGR DPF FAP | eBay and once it arrived proceeded to copy my ECU using the guide on the website. The only issue I had here was an error about half way through but pulling fuse 15 (instrument cluster) did the trick.
I then emailed this map to Andrew at blacksmoke, as my ECU code wasn't listed on the website, in the afternoon and by the same evening I had a new map in my inbox. Now I was going to to some before and after logs with VCDS but I thought, sod it, get it on there! Uploading went without a hitch and the engine fired up first time. One recommendation I would make here is to pull fuse 4 (radiator cooling fan) as this kicks on during read and write operations and drops the battery voltage, in my case, by 0.6V. This would drop my battery voltage below the required 12V which is not good, apparently.
I've done a few good thrashes now and what a great improvement! Before the remap, my car had no interest in pulling beyond 2nd gear. Now it pulls like a train all the way up to the red line in 5th at a 3 figure speed. I can live with the lack of pull in 6th at these speeds.
And the best thing is, no fault codes and no clutch slippages (yet)!
Only time will tell if I see an improvement in MPG but that's an issue I'm struggling with anyway. I've had the car 6 months and calculated 38 MPG in that time with mixed driving and only using Shell Vpower or BP Ultimate. I have read every post going regarding the "issue" and nothing is at fault. I done a bottle of millers and a liqui molly diesel purge too, with no improvement. I'm kinda resigned to the fact that it's the norm for my engine...unless anyone can enlighten me?
Overall, highly recommend the service Andrew supplied. He answered my questions and provided the map very quickly!
I'm driving a 2005 A4 Avant B6 1.9 TDI 130 Sport with 146K on the clock. It's an AVF engine so has the 6-speed gearbox. According to Andrew my gains are 130bhp to 162bhp and 310Nm torque to 390Nm torque. For a total of 60 quid for the lead and map, it's a no-brainer!!!
