Did the cleaning work?

I'm curious what the final word on this situation was. I'm having similar problems and have come to think it could be the EGR valve. Any thoughts for or against this?

I'm experiencing some of the problems you have mentioned. I'm wondering if it could be the EGR valve. There are quite expensive so I'm going to first try cleaning mine. Have you thought about this valve? Wouldn't describe the misfiring but the sluggishness and bad performance when accelerating.

The gasket leak was earlier before the bosch reading and was visible from examination under the car and I was losing coolant quite quickly. After the gasket was replaced, as well as the timing belt, water pump and a few other things, the engine light came on. It was at this point that the mechanic found an error via the bosch reader and determined it was a sensor. That problem is fixed but now the EPC light started coming on, though intermittently.

Thanks for the feedback. I haven't had my car go into limp mode yet. I'll assume that it still knows when it needs to, so the esp light might not be indicating anything terribly serious at this point- we'll see. Sorry, but I'm not sure if 4-up means 4th gear and above? Also, by "cat", do you mean the cat-back exhaust system? I'm a "newbie" on this forum and obviously in lingo as well. ;-) Anyway, it seems clear that I need to get further diagnostic work done. Asking people on this forum to trouble shoot something like this is asking a bit much. It could be many things it seems. Regardless, I'll post the results.

2005 Octavia II 2.0 FSI 91000km A year ago I had the head gasket replaced. Shortly after that the engine light came on and we determined that a P2540 fuel low pressure sensor - range/performance error had occured and I needed to have the sensor replace. Before I did this, the EPC light started intermittently coming on and couldn't notice any particular pattern as to when and no performace changes - nothing obvious anyway. My mechanic suggested that the engine light (P2440 pressure problem) was related and it would stop once we changed the sensor. Well, the engine light doesn't come on anymore, but about 5 minutes after driving away from the mechanic the EPC light came back on. I know that it could mean many things, but I'm just trying to get as much information as I can before I go back to my mechanic (or to an authorized dealer). Any thoughts out there on this one?

Just a little update on my Octavia, post head gasket repair. Had the head gasket replaced in spring 2010. After that the engine light came on indicating the error P2540. Fuel low pressure sensor - range/performance. One guy on this forum suggested that during the gasket replacement, the sensor may have got damaged and that is what caused this error code to show up, but my mechanic did not agree with that one bit. Anyway, I had the sensor replaced after about a year, but before that the EPC light started coming on from time to time. I couldn't notice any sort of pattern as to why, nor could I notice any changes in performance - nothing obvious anyway.My mechanic said that it was likely related to the sensor in need of replacement (the error 2540 problem), but 5 minutes after picking up my car from the mechanic the EPC light came back on. Fortunately, replacing the sensor seemed to fix the engine light problem at least but not the EPC. Any thoughts regarding what COULD be the problem here? I know that the EPC light coming on intermittently could mean many things, but if anyone has an informed guess, let me know.

Yes, it's an FSi 2.0 110w

So, I had a visible raditor fluid leak below my car back in May of 2010. Had the head gasket replaced and did a few other replacements while we had things opened up in there, e.g. timing belt, etc. I joined Briskoda shortly after that because after the work had been done the engine light immediately came on and we eventually determined that it was a P2540 fuel low pressure sensor - range/performance problem, which as one member in Briskoda suggested may have occured while the timing belt was being replaced. My mechanic, however, disagreed and of course didn't agree to cover those new costs, but spent a lot of time proving it wasn't anything else. Anyway, here's the problem now. I am losing, most likely burning, coolant again and about every two weeks, depending on how far I drive, I have to top off the radiator fluid. Clearly, that's too often and either the new gasket didn't hold up OR that wasn't even the primary problem in the first place. The heads were, of course, shaved down before the new gasket was put in and apparently there was no sign of warping. I cannot visibly see the leak as I could before the gasket was replaced, but regardless I'm losing (or burning) fluid somehow. Any ideas as to what could be going on? Worst/best case scenarios? Diky moc za pomoc! (that means "thanks a lot for the help" in Czech; thought some of you guys might get a kick out of knowing a few words or two in Czech, being Skoda lovers and all...)

Has anyone ever had a problem with their side-view mirrors? I recently noticed that my driver's side, s.view mirror was shaking so much while driving that I could barely use it to see what was behind me. Was more than abnormal. I grabbed the glass and tried to sort of wiggle it a bit to see if sth seemed obviously loose inside, but nothing was. Then, when I shut the door, I could hear a something like loose springs vibrating. The only word I can think of to decribe is perhaps "boing...". Then, as I was cleaning the glass part of the mirror, the glass fell off. As you may know, the glass is glued on. So, I intend to find some type of adhesive and reattach it this weekend. Still, the question is: what could it be inside the casing that is loose and rattling and perhaps caused the glass to come off? I should point out that I think I was playing with the glass with too much force while trying to see what was causing the rattle sound and the shaking, and this may have been the main reason it fell off, though it could certainly be a combination of both. So, does anyone out there have any experience with a s.view mirror replacement or any experience at all that could help me figure out what the problem could be? I've never diassembled a mirror. I assume I will have to remove the door panel first and will read up on that before I try, but what could this problem be? As always and like most car owners I know, we want to solve the problem properly but to not have to spend a silly amount on things like this. ;-)

Thanks for your reply. I've heard something similar to what you wrote about the diesel-like sound enough times recently that I should just accept it, especially when I consider the performance alone; this engine is probably the most responsive 4 cylinder I've ever driven for a car of this weight. I'm curious, how has your Octavia treated you since you got it in 2006? Satisfied? Have you had to do any major repairs to your Octavia? I thought having my head gasket go bad at 80 000km seemed a bit early, but I've heard it is relatively common for Octavias of this type and I'm hoping it is the result of poor quality gaskets, nothing more.

Thanks for the tip. I'm sorry I didn't see your reply earlier. My settings on this forum indicate that I should get emails sent to me if someone replies, but I haven't receieved anything. Anyway, my mechanic has since the time of my first post concluded that the fault is not in the wiring but in the sensor itself, so I will have it replaced and then we'll see. I've had some other people suggest that it was probably wiring damage while the timing belt was being replaced, but if my mechanic disagrees, there is not much I can do besides taking it somewhere else - an option I'm not quite ready to do yet. It took me quite a while to find a guy I trusted. I hope I can say the same thing in years to come about this particular guy. The fact that he did at one point tell me that this sensor is in no way connected to the work that he did seems a bit odd as I learn more about it. This may be slightly off the topic, but by chance that I catch you again, I've got another question. As my original post mentions, I've got an Octavia II FSI 2.O 110Kw with about 85000km on it now. I was initially quite taken back by the diesel-like, almost unhealthy sounding engine in idle and first gear, but was reassured that it was quite a normal sound for this type of engine. After a few weeks I grew a bit weary of this sound being "normal", assumed I had a hole in the exhaust manifold and took it to a shop that only does exhaust systems and they told me there is no problem with the exhaust system but that the engine did not sound healthy at all. I pushed them to explain themselves, but got very general answers, nothing specific and my conclusion was that they are just not familiar with this type of engine. My mechanic says there is absolutely nothing mechanically wrong with the car and had a chance to look closely at things when he replaced the head gasket (presumably) so I decided it was best just to trust him, however, just for a piece of mind I am trying to get as much information as possible (joining this forum was a start) and have since got a second opinion from another mechanic indicating that these engines just sound that way. What exactly is the reason for the rough sound? If it is normal can a light knocking even be considered ok? I've never owned a diesel, so this further adds to my uncertainty about this engine noise. Let's assume it is mechanical and the "rough" sound isn't entirely natural for this type of engine, what are some of the possible problems it could be for an engine with only 85000km? Thanks in advance if you find time to answer my questions.

I don't know if this means anything more than the error code itself, but the recent information I got was that it is a P2540 error: low pressure fuel system sensor, circuit implausible. Any ideas what I'm looking at here and why this may have suddenly occured after having the head gasket replaced? Thanks, Daniel

Glad to have found a forum like this! I'm an American living in Brno, Czech Republic and it's nice to read about Skodas in English language, although admittedly it is a bit odd as I live in a country where 1 out 3 cars is a Skoda. Still, the point is the ease of communicating in my native tongue, even if I speak a slightly watered down version of proper English. ;-) I own a 2005 Octavia II 2.0 FSI 110kw. I have a post under the Octavia II section where I discussed having recently replaced a head gasket and have since had a problem with the engine light coming on, last diagnostic indicated a P2540. Fuel low pressure sensor - range/performance. I describe the problem and ask for advice in my post under the title " 2005 2.0 FSI" so have a look if you are interested or might be able to help. Anyway, I guess I should just be saying hello here and not delving into the problem. Thanks. Daniel

I recently bought a used 2005 Octavia II 2.0 FSI with 80 000km. I bought the car after doing a fairly comprehensive diagnostic using a Bosch motronic device and the eyes of a certified Skoda/VW mechanic who inspected the car quite thoroughly. We discovered that the head gasket would need to be replaced if I planned to buy it. The gasket's fault was minor and there were not any signs that it had started to effect performance at all, no frothy oil from coolant leaking into the oil chamber either. I was able to negotiate the cost of this work off the total cost of the car, so I decided to take a risk and bought it. The car's exterior and interior were both in mint condition and mechanically the car checked out, other than the worn gasket (and of course the potential hidden problems which may have contributed to the gasket's failure). So, I had the gasket replaced and decided to take care of some other things while the mechanic had things apart: new water pump, timing belt and pulleys, gas filter, new plugs and a few other things I can't think of right now. After two weeks, the job was done and I was free to go. Keep in mind, I had only driven about 1500 km after buying the car and before taking it in for the gasket change, so I was eager to finally drive my "new" car. During that time, there was no serious loss of oil or coolant, so the gasket leak was in fact barely noticeable; replacing the gasket was fortunately only a preventative repair at that point. After I got the car back, the engine light came on after about 15 km. Returned to the mechanic and his tests revealed very inconclusively, or rather quite generally, that there was an air pressure problem, so he slowly went through all the hoses and found one that seemed weakened and replaced it. Got the car back, drove another 50 km this time, light came on again. At this point, my mechanic decided to double check his work, so he concentrated on checking that the timing was in fact set properly (which it was) and concluded that there was a gas pressure problem and found a cable that was faulty (although I am not entirely sure exactly what it was -- I should point out that I live in the Czech Republic but am originally from the USA, so even though I speak Czech relatively well, certain things go over my head, especially when talking to mechanics). Got the car back again, managed to drive an amazingly smooth 175 km before that light once again came on. Went back to the mechanic, did the diagnostic and the final error code reading was this: P2540. Fuel low pressure sensor - range/performance. My mechanic is too booked up to deal with it straight away, so I am using this free time to get a second opinion. I trust my mechanic, but he's had my car longer than I have since I bought it in March and I think he may need a break from getting a phone call from me every two days. My question is, has anyone else out there had any similar problems with this particular engine? Is it just a coincidence that this problem started happening just after the head gasket, timing kit and that work was done? Mind you, I had absolutely no troubles during the 1500 km I drove the car before I took it in to have the gasket replaced. If it isa P2540 error, what could this mean? Worst/best case scenario? Thanks in advance for anyone who chooses to dive into this with me.
