    A6 3.0TDi BMK often won't start when hot. No fault codes, what to investigate?

    Afternoon mate, yes I did, I should have updated the thread at the time! In my case it was the crank speed/position sensor. From memory it’s located near the bellhousing on the back of the block, possibly at about the 9 ‘o’ clock position on the bellhousing when viewed from the back. It was a...

    Budget brake upgrade: Q7 brakes and or ducting, anyone done it?

    That's a great link, thanks very much! I will look into S6 brakes. It doesn't talk about fitting any of them to a 3.0 TDi though.

    Budget brake upgrade: Q7 brakes and or ducting, anyone done it?

    I had a feeling you'd come through with some good info Karl! Thanks as always mate! I'll look into high temp fluid now, I'm sure even changing the old fluid will make a noticeable difference. As an aside, does anyone know if the master cylinder would be ok with a pressure bleeder (gunsen ez...

    Budget brake upgrade: Q7 brakes and or ducting, anyone done it?

    Interesting! I'll double check later, but I'm pretty sure I bought 321mm vented for the front when I did them last! I know there were two options for my year, and I think mine were the bigger of the two. You say originally, what are you running now? Sent from my iPhone using Tapatalk

    Budget brake upgrade: Q7 brakes and or ducting, anyone done it?

    Good morning all, I hope you've had a good weekend! Mine has been eventful! I have discovered just how limiting the 321mm single pot brakes are on the front of my 2005 3.0 TDi quattro. I managed to set fire to them after some 'spirited driving'. I'm not exaggerating when I say set fire to them...

    Rear Indicator LED bulb flicker

    I don't believe it is possible to disable the bulb monitoring. I have fitted LED DRLs and Sidelights to match my factory xenon color and they do exactly the same thing for the same reason. It may be worth dropping T8UPS a message on here though as I'm sure he's looked into the issue in the past.

    Exactly, it was the first week I had it and I assumed the DIS was fairly accurate. Yes, but the fuel gauge is also not particularly accurate either. IIRC there is a procedure for calibrating the fuel gauge, but I've not done it. At the moment the first half a tank is more like 2/3, and the...

    Sounds good to me. In tank pump shouldn't be too bad. there is an access hatch under the carpet right behind the seats in the saloon. There is a sloped piece of plastic with a hatch in it, that cab be removed, and then I think there is a rubber or plastic cover over the actual access hole. It...

    Yes that's a definite possibility. How old is the filter? Unfortunately it's a sealed unit, so it's not possible to have a look at the filter element and check for contamination. Clogged in tank pump strainer is also quite possible.

    Yes this could definitely cause it! If it's very low on fuel, the in tank pump may be struggling to get enough fuel to properly prime the engine. As a side note, my C6 3.0TDi is the only car I've ever run out of fuel in! The range lies almost as badly as the DIS MPG, I ran out with 30 miles...

    Silly question

    I have found in heavy traffic that sport mode uses less fuel. It is much more keen on downshifts, so is using more engine braking and therefore less fuel. For anything else I completely agree, it drinks like a fish! It's still a lot more fun though!

    A6 3.0TDi BMK often won't start when hot. No fault codes, what to investigate?

    Morning all, this problem is now happening with more frequency, so I have had a chance to investigate more with VCDS. I've checked the coolant and fuel temp sensors, I've never seen fuel temps above 78deg and coolant temps above 84deg even when it's not starting. I've checked the rail pressure...

    A6 3.0TDi BMK often won't start when hot. No fault codes, what to investigate?

    I'll have a read on my lunch break, cheers mate. I know it was a big issue with the early 2.0tdi, but it could be mapped out. I had the hot start fix done on mine when it was mapped. I've not seen anything to do with a known hot start issue on the 3.0 though, but I'll see what I can dig up.

    A6 3.0TDi BMK often won't start when hot. No fault codes, what to investigate?

    Cheers Karl, I'll have a look at those when I'm home tonight. Presumably it will refuse to start if either the fuel or coolant temps are too high? If it happens again, I'll log the fuel pressure again and see how reliable it is under cranking. I'll check the in tank pump later, does it run all...

    A6 3.0TDi BMK often won't start when hot. No fault codes, what to investigate?

    Good morning all, Over the last few months my 2005 A6 C6 3.0 TDi has developed a hot start issue. When it has been on a good run and is nice and warm, it will refuse to fire. It is now happening more than once a week! It will always crank perfectly, for exactly the same amount of time (about 3-4...

    3.0 TDI BMK new injectors fitted, running nicely but now smoking even worse on idle! Where to invest

    Haha I'll give them a chance for a few days then. I've got a 35 mile round trip to work, so that should give them a bit more of a gentle run!

    3.0 TDI BMK new injectors fitted, running nicely but now smoking even worse on idle! Where to invest

    Got you, hopefully they will settle at reasonable values. Am I correct in thinking those values are a timing offset in ms from the 'ideal' injector timing? Or is it more related to the flow characteristics of the injectors? I took it for a really hard run just now at 120+, the brakes overheated...

    3.0 TDI BMK new injectors fitted, running nicely but now smoking even worse on idle! Where to invest

    Only been in a few hours and done about 3 miles! It sounds like I should give it a few days, if it doesn't get better I'll order a set of 6 new crush washer and 6 new o rings and do the job again with them. I took out and checked the one I re used, I couldn't see any reason for it to leak...

    3.0 TDI BMK new injectors fitted, running nicely but now smoking even worse on idle! Where to invest

    Afternoon all. I've just replaced all 6 injectors on my 3.0 TDI BMK with used low mileage later revision units (I had 059 130 277 S, which is the original revision, I have just fitted 059 130 277 AH, which seems to have no issues). I did this to cure the well known injector failure on this...
