I keep getting emails and PM's regarding 3.0TDI tuning so thought I'd post my build thread here too.
It was already on ASN but I seem to be doing more A5's
14/7/15 - Introduction
Well it’s been a while since selling my Golf ARL. Those that are aware will know it made over 300hp from mixture of custom made parts when no 2260 kits were available.
So the new project car is Audi A4 3.0TDI estate (CCWA engine code) - 240hp model auto (TIP) - I didn't want a manual. The auto box has reported torque limit of 700nm.
Decided on a B8 simply because the early ones suffered from injector failure causing engine damage and they don't come with the 2260 as stock.
Even though the car came with full Audi history the air filter is in a poor state looks like they've changed only the oil and filter the last few times.
First action plan is to service it soon and ask my cousin @ teamspb to give it a detail.
Here are some pics
Good news I don't think anyone has been in there

15/7/15 – Read attempt
I had some time yesterday so attempted to read the ecu, but failed to get a read out.
Further digging has shown that software 0006 is boot mode only - basically ecu out job on the bench.
I'll tackle that on the weekend.
Fixed the Fuel cap motor wasn't locking (common problem so worth trying a bit of cleaner first) and the rear wiper jets weren't working.
20/7/15 – Boot mode & service
Carried out some more work on the car this weekend.
Removed the ecu and using a heat gun, blade and patience removed the bonded cover:
Got a successful read of all memories in case I ever need to clone the ecu
Next job service (air, fuel and pollen)
Detailed
Yesterday got my cousin from (teamspb) to do the detail on the car
This week I'll prepare a stage 1 tune (with egr off) and see what it does - I've unlocked the ECU for obd tuning so will make revision uploading easier.
17/8/15 – Air box butterfly, Stage 1 tune & DPF pipe
Removed the air box butterfly
Also, started work on the tune.
For stage 1 I want to keep stock hardware including DPF and just remove EGR from software.
Even with the correct damos file this sofware it's not a easy task over 20k labels.
I was being limited to 620nm torq limit - but finding the limiter for this has resolved this issue.
Anyways after many revisions (all over boot mode) the MAF (hfm) is maxed out and remains flat lined after 3.5k
EGR is off via software
Nice punch in the midrange with healthy IQ of 86mg
It’s nice to see the fuel pump is keeping and there is no pressure drop so far.
For stage 2 (DPF off) I will replace the MAP sensor with a 4 bar unit and change the tune for a maf delete (this will not be an easy job and will require many hours in calibrating fuel)
I will book a dyno slot this week and see what it does.
DPF delete will be with me soon
22/8/15 – Stage 1 dyno
Made it to the dyno today
Stock car with stock map:
Stage 1 tune with stock hardware (inc dpf):
313hp 650nm
Pleased with the result
Just a shame I went on such a hot day. My air charge temp were showing 80deg on the dyno runs. I need to confirm at what temp does the torque limiter kick in.
More digging into the map tomorrow.
Next fit the 3" dpf delete pipe, remove the egr and maybe the maf.
24/8/15 – DPF removed
Removed the DPF pipe yesterday and fitted the 3" delete pipe.
