    3.0 tdi .... Goes flat in 5th gear only ......

    The gearbox remap helps, but the going flat in 5th is a torque limiter is in the engine ecu. It’s not easy to find

    @Gazwould I have done just that, and it doesn't sound anything like the performance exhausts on YouTube on the 3.0tdi A5 's and alike On WOT it sound angry yes, a ripping boosty sound - but you only get a very slight v6 note - 5db increase over standard

    @David Hunter What car is it you have ?? You won't need any tape for the cut outs around the rear exhaust there is suitable air flow between the outer edge of the exhaust tip and the bottom edge of the valance for enoug air to pass to cool it

    Nope, no drone The only time the tone become slightly more audible is in the regen cycle, not I'm not talking loud, you just get alittle deeper v6 sound during this period As I do about 1000 miles a week I wouldn't want anything that's noises or annoying

    My friend got in my car today, we whet mountain biking at Sherwood pines, he knew that I had planned to to this, but didn't realise I'd done it - we did about 20 miles before I mentioned it ! quiet as a mouse and that's with my straight pipe version

    What power can the auto box take? 3.0 TDI paddleshift

    The power (bhp) isn't so much the issue....it's the torque - iirc our boxes are rated to 500 lbs/ft the torque covnverter will be fine Personal I find the zf g/box poor and slow to respond in all modes really - the 6hp19 isn't great IMO - the 6hp26 I had in my 335d before wasn't great but it...

    Karl, the added heat on the modified silencer will be from the extra flow. The modified side will be getting 2/3 of the gasses as the n/s is in effect blocking the gasses so they're taking the easy way out....the o/s freer flowing side. Nice neat job btw, looks well done. Any reason for...

    Well, i've been running this tweak for about 900 or so miles - it's all positive so far The car is fully adapted now, the cars exhaust note inside hasn't changed, it's note outside has stabilised - very subtle v6 burble as I have my DPF in place still Until the DPF dies it'll remain in place...

    Mini update - circa 250 miles covered, mixed driving, my initial impressions are that you need allot less throttle input to achieve speeds where previous throttle inputs have had to be greater feels allot less breathless at the top end of the revs too fuel econ seems to be slightly better...

    Amazing result from mufflerectomy tested on dyno

    Decided to give this a go on my car today - please note - MY CAR IS EQUIPED WITH A DPF I am NOT expecting the types of gain as the OP, but I am expecting a noted difference in the power delivery, power band and economy. My exhaust, 09 plate facelift 3.0 tdi with dpf, was the same setup as the...

    Amazing result from mufflerectomy tested on dyno

    my reference was to the power increase, not to the power curve yes the compound charged 35d engine (twin turbo) single waste gate) comes on sooner and lasts longer than the singal turbo set up but removing the restriction in the flow of the exhaust (and the a6 rear silencers are extremely...

    I've seen this on the 335d, I had a coupe and so was on e90 post, a couple of chaps did this - all had similar results from just the exhaust change results ranged from 15bhp to 21bhp i cannot recall the torque figures for them though if the exhaust on our 3.0 tdi cars are that restrictive I...

    3.0 tdi .... Goes flat in 5th gear only ......

    fuel system was down to swarf in the system, a component breaking down - it was a recall for certain engine codes and sizes swirl flap rods - common issue inlet o ring - relatively common issue again, you'd see an oily buildup around the pipe at the turbo end on the compressor housing They...

    The car : Audi A6 3.0 TDi Auto Quattro 2009 facelift CDYA engine code The problem : Hold a constant 2/3 's throttle - run through the gears without deviation - 1,2,3,4 all pull strong, smoothly drops into 5th and goes flat, still accelerates, then pulls strongly again in 6th The fuel...
