Same kind of feeleing, when you are running outta of gas, but the tank is quite full! Also I think that it might be problem with cluth, but who knows...<p>2morrow, I'm going to service. Will se what happens. But if someone has any kind of idea, what it might be, be free to tell me <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0">

Re: Diesel probelms :( I think (tomi22)

EGR problems and a batch of bad clutches I have heard. All should be covered under warranty.

Re: Diesel probelms :( I think (Johann)

Mine does this every now and again. Mine actually seems worse for a short while after service. <p>I am on 40K miles (well will be tomorrow). The car has had the relevant software updates and has also had the EGR problem one morning at avout 28K miles<p>Not bad enough for me to pursue the dealers about - as I am sick of them dismissing such things.

Ok, so I just came back from service. I told them everything what I have written here. They had it chcecked by the computer, and... discovered that Volvo already issued a software upgrade in order to solve this problem. They said that they had "few" (3-5) cases like that, and everythime software upgrade, advised by the factory, solved the problem. If it shall happen again, they will look at once again, as soon I will have my first maintenance service. Currently I'm on 14500km (8787miles) and in 5500km (3333miles) I have to have my maintenance - about 2 months. <p>Also they said, that car is loaded with all kinds of sensors, and if they are not saying anything, then it is ok. But they cant guarantee that nothing will happen - this I understand, its simply beyond the control. <p>After this upgrade, I have a feeling that car is a little bit more "aggresive", I don't know, but I think it runs better. Well they said that the engine was tuned from the beggining, whith this upgrade. Also I think that they did something with clutch, as it runs also better, then before. But this they didn't tell me, and I dont expect them to tell me - as long as everything works, I don't care <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/biggrin.gif" BORDER="0"> <p>So now its seems to be ok, will see how it goes later. At least they said that the problem wont make me be stranded on the autobahn <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/cool.gif" BORDER="0">

I had the same thing, accompanied by a burning smell when you get out of the car (only happens every few hundred miles).<p>The dealer reflashed the ECU with the updated software as per the above post.<p>However, it's doing it again. I read a post on another forum where the owner had had numerous reflashes and a couple of replacement EGR valves but still no joy.

Re: (MarkE)

I think that EGR Valve is outta of question, as they said that IF the emissions level is to high, then sensors should be flashing, saying STOP, maintenance required. Nothing like that happened.<p>They also said, that they had only FEW cases like that, and UPGRADE of ECU helped. BTW, they said that it is NOT a reflash, but FACTORY solution, made specially for this kind of problems. Unfortunately they did not tell me exact factory explanation, and I did not aske them for it.<p>Also, they said that it should not cause any problems - I hope so <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/rolleyes.gif" BORDER="0"> <p>Also, as I said, the car seems to run smoother, which is not a surprise, as they said that this upgrade is also responsible for... engine tuning and fuel injection sequence.<p>I only wonder wht it took them 3 hrs to do it <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0">

Re: (tomi22)

My guess is a reflash is done to make adj to EGR duty cycle.<br>From factory it may be a little too aggressive with a tip of scale<br>towards emissions rather than performance.<br>I wouldn't bank on the emissions warning, sure if REAL bad, else no.<p>This re-flash could have been monitored if you had a scan tool and checked normal cycle values before you brought it in and then after.<p>Doesn't sound like something you'd have done....<p>Still might not be out of the water with egr, they are prone to sticking, cloggin up, particualrly if you baby your diesel or most drives are short city like commutes.<BR><BR>

Re: (Dzljet)

Perhaps... who knows. Anyways, soon I will have regular service, and I will write all those EGR and other ideas on a paper, and ask them to check it. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0"><p>

Re: Diesel probelms :( I think (Richard_S40)

Yeah, but fault is on teh side of... electronic progress. Todays cars are loaded with sensors, practically everything can break in no time <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/frown.gif" BORDER="0"> Tehy also said, that if it will happen again they will have to take engine - well injectors and all - into parts and carefully run a check <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/eek.gif" BORDER="0"> <p>This scares me little bit, but to be honest, I will change mine in one year anyway <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0"> 2.0 Diesel into D5, which now came into sale <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0">
