    2.0 tdi 140.

    Mine would smoke before I did my injector seals... there’s a load of things it could be though. Worth getting it on VCDS first to see what’s going on.

    2.0 TDi 140 PD - Rough idle and misfire...

    OK, its taken ages to sort this, but it is now fixed. I'm not sure if anyone's interested, but I have seen so many similar threads on forums that never get updated with an answer, so I wanted to get this on here! So, I removed injectors 2 and 3, and cleaned up the tips with carb cleaner. I...

    2.0 TDi 140 PD - Rough idle and misfire...

    Right then, its taken me a while this one... but I've taken the fuel filter off today, and the fuel inside is black. Not thick with oil, it looks clear as you pour it, but once it's in a jar it looks black. Clearly something is going on and I think it's the injector seals. PLan now is to order...

    2.0 TDi 140 PD - Rough idle and misfire...

    I’m well aware of the BLB oil drive issue... I spent a week with it off the road while I removed the balance assembly and sent it off to be re-engineered with the longer hex shaft. That was over two years ago now; luckily I was able to stop the car immediately on seeing the warning light and get...

    2.0 TDi 140 PD - Rough idle and misfire...

    John Clutton... that sounds like 'limp mode'... mine did that when I blanked off the EGR valve, before I had the EGR mapped out. So in light of some of the above suggestions, my car has the EGR valve present but blocked off and the engine map allows for this. It does not have a DPF. My cable...

    2.0 TDi 140 PD - Rough idle and misfire...

    Thanks for the suggestions... my cable hasn’t arrived yet so no progress. I’d have thought if it was an injector then I’d lose top end power.. ditto if it was the injector loom or worn camshafts. Plus this is when it’s warm rather than cold, so I’m not sure it’d be glow plugs. My google...

    2.0 TDi 140 PD - Rough idle and misfire...

    Thanks guys, that's a good list of suggestions. I've got vcds cable coming so that may help... I like the suggestion about the breather pipe... I do most of my own maintenance so maybe I've knocked something by mistake. The trouble with these cars is their complexity... various things could...

    2.0 TDi 140 PD - Rough idle and misfire...

    Hello all... I have a 2005 A4 Avant, 2.0 TDi 140 PD (BLB engine), with 177,000 on the clock. I've had it for nearly 5 years and it's been great, but 6 months ago it developed a really rough idle. It now takes a while to start, runs rough for the first 30secs or so, and settles down to a smooth...

    2.0TDI LUK Clutch and DMF

    I've just had this done in January. I bought the clutch, DMF and slave cylinder for £430 online, and had a local garage fit it for £200. I've got a 140 TDI, remapped to about 175bhp, and it doesnt slip for me. I think the same clutch is fitted to both the 170 and 140 though, so I knew I had...

    A4 BLB EGR delete...?

    Yeah given that I've had water drip out of the EGR cooler I'm pretty confident it's that and not the head. I'll bypass the coolant flow through it and see if I still get coolant loss. 100mm hex drive was fitted a couple of years ago after I lost oil pressure. The car is 12 years old with 176k...

    A4 BLB EGR delete...?

    hey guys, I've got a 2005 A4 Avant, with the 2.0Tdi BLB engine. The car has been losing coolant for ages now, about a litre per 100miles, maybe a bit more. I've kept it topped up and it's been ok, but it is getting annoying. Anyway, I figured it could be the EGR cooler. I get white smoke on...

    Stupid question... What are these bolts?!?

    It's ok, I realised what they are... They are the bolts that pass through the rear of the sump and into the block, at the flywheel end. The car is back together now and luckily, the engine and turbo are both fine. Goes to show you should stop immediately if the oil pressure light comes on! I...

    Stupid question... What are these bolts?!?

    Hey guys... This is a stupid question... So over the past couple of weeks, I've been replacing the balance shaft in my 2.0TDi A4 (B7) which had the hex drive fail. I took the car apart two weeks ago... Removed the bumper, put it in the service position, lifted the engine, dropped the...

    New stereo advice

    What do you want to get from the upgrade? Better sound, more connectivity, sat nav? Cheaply eBay jobs won't get you far I shouldn't think. Audi sat nav should be an easy fit but might cost a bit. Some of the new Pioneer double DIN units look smart and will control an iPhone etc. I'm going for...

    New pioneer install

    Did you swap any connections while the head unit was powered up? Pioneers are well known for blowing the tiny fuses that sit on their line-out circuits. This causes a thump through the speakers when you change some settings. I had it happen on my old 77MP and had to send it out for repair.

    Audi S4 Avant B7 Progress! 358bhp

    If I'm reading that correctly, it's 262 at the wheels, and 358 at the engine... So these cars lose 100bhp to the transmission? That seems pretty high... I dread to think what mine actually puts down on the road then... Not a criticism though, it's a nice car ;)

    Springs / shocks for B7 Avant 2.0TDi...

    Cheers, will do. Also I've noticed that the rear of the car seems to sit lower than the front... Not sure if this is normal, and is it likely to be level once I swap to a new set of springs?

    Springs / shocks for B7 Avant 2.0TDi...

    Hey guys, So my Avant 2.0TDi SE needs new shocks as the old ones are leaking a bit, and it also needs new bushes in the front suspension. The car had 160k on the clock so I was thinking of putting new springs on as well, so the whole suspension is refreshed. It's a family car, so some...

    A4 Avant suspension and tyre questions...

    It's not an S-Line, just a regular SE. I've not done the tracking... Ive had poke around with a pry bar and some of the bushes are definitely knackered, so I'll do the lot while I have the car apart. I'll get the tracking done afterwards. Not sure the rear end is adjustable at all though, which...

    A4 Avant suspension and tyre questions...

    hey guys, I've got a few problems with my 2005 A4 Avant TDi... It's due an MOT soon, and has a lot of play in the front suspension. I intend to change all of the bushes at the front, and the drop links. Am I best just buying standard, or are there any updated parts I could fit to improve the...
