because I had noticed that the car was slightly hesitating every now and again ( once a week, something like that). After much debating with the dealer, I ended up paying to have the part replaced out of my own money rather than warranty. After reading some posts on SS, there were several recommendations that even if the part is not faulty, it is probably good idea to replace for the cost and the amount of miles on the car 45K. So, I picked up the car last night and it was zooming around. Not sure if it was the cooler temps in NJ or the part itself. But either way I was satisfied. Turned the car on today and sure enough the hesitation is back. What now? I remember someone stating the solenoid could be the problem? I also remember reading there is a 3000 RPM hesitation? Can someone please shed some direction? Thanks.<p>

<br>It could also be the fuel pressure sensor or the fuel pump.<p>The fuel pressure sensor sometimes trows a CEL and a code for the dealer to read, sometimes not. May be you could ask your dealer to change it as a try out, if that is the problem you'd pay for it (or get it via garrantee), if the problem continues you'd return to your original sensor. That sensor is expensive, around $250 or so.

Re: So I had the dealer replace the Turbo Control Valve on my car... (Jayam)

they had mentioned that they had checked to see if there were any codes and none were found.<p>When you say the fuel pump, what would be a sign that it is failing? Hesitation? Or does it consistently underperform?

Has this car had the Volvo ECU upgrade from late 2004 installed?<br>This fixes this problem on 99% of the cars

Re: So I had the dealer replace the Turbo Control Valve on my car... (JRL)

yes, all the current upgrades have been installed and verified by the dealer. What I'm afraid is that is we won't see any more hot weather and when this problem rolls around again, it will be past the warranty. Has anyone replaced the solenoid yet? Where exactly does that sit, in the air intake manifold downstream of the TCV?

Re: So I had the dealer replace the Turbo Control Valve on my car... (R Crazy)

For me it was the fuel pressure sensor, but I did get the fault codes.<br>It is quite a bit cheaper than replacing the fuel pump. About $350 with the labor. Part alone $200, if you want to do it yourself, but you need to drain the fuel injection system, remove the charge air pipe over the engine and remove the cover over the fuel rail to get set to remove and replace the sensor.

Re: So I had the dealer replace the Turbo Control Valve on my car... (MagoonR)

If the pump is not working properly, would a code be created?

Re: So I had the dealer replace the Turbo Control Valve on my car... (Cicada)

well sure enough now a check engine light has come on. man, when it rains it pours. And of course it's a holiday weekend and there is no way of letting them know I am going to be there Tuesday morning with the car. I am really frustrated. We'll see what the code is. I hope it has nothing to with the recent TCV I replaced.<p> <IMG NAME="icon" SRC="http://www.vortexmediagroup.com/images/banghead.gif" BORDER="0">

Re: So I had the dealer replace the Turbo Control Valve on my car... (needsdecaf)

I would hope the dealer connected the hoses!!!!<p>With the check engine light, some code has to be on the ECU, right??? We'll see what it is on Tuesday. My patience just keeps geting shorter and shorter.

Re: So I had the dealer replace the Turbo Control Valve on my car... (R Crazy)

so the MAP sensor was bad and caused a code and was repalced. I haven't picked the car up, but has anyone else experienced this? I am dying to see how the car is going to respond tomorrow. Does the MAP affect performance at all?

Re: So I had the dealer replace the Turbo Control Valve on my car... (phuz)

that would explain the hesitation that I was feeling. After replacing the TCV, it had to be the fuel pump or this sensor. It's all coming together now.<p>Thanks for the info.<p> <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0">

Re: So I had the dealer replace the Turbo Control Valve on my car... (23109VC)

car is driving great, although for some reason it feels a tad bit slower with the new MAP sensor than the one that was faulty (after replacing the TCV). Maybe I was getting too much gas??? Either way, the car is a lease and thank god I have another ~2.5K before the lease expires, so the cost was a big fat $0. If this happened a few months from now I would have been SOL. I am sure in retrospect that the new TCV had something to do with the MAP sensor finally throwing a code to the ECU even though the car was hesitating before I changed the TCV. So I think the MAP sensor was starting to go then I changed the TCV (mis-self-diagnosis) and then it couldn't handle the new TCV and threw the code.<p>Might keep the car. Still debating.<p> <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/confused.gif" BORDER="0">
