i have heard it’s fine to bypass the cooler as you say you did with your audi. but i have been told that as long as the egr is bypassed via the software in ecu then you do not have to physically remove it and blank it off. but you do still have to bypass the cooling side. this sound right to you?

no i haven’t had it done. think i’m going to try to bypass the cooler part with a pipe or hose that will prove that’s my leak problem. just means the egr valve will not be cooled just like on most other diesels. if that works i’m going to remove the unit completely and blank the egr. already been quoted £69 to have the ecu software done when the egr is removed.

i think i have a problem with my egr valve so searched google and youtube. looks like a big job on the tdi cr engine at around £1600 for a dealer. apparently its at the back of the engine at the bottom. drive shaft etc has to come off to gain access to the water cooled egr valve. but this is on the 2.0tdi cr engine ( my octavia vrs engine) not sure what yours is.

hello all. car has a problem. occasionally it struggles to start but goes after 3 or 4 attempts. when it does start i get clouds of white steam from the exhaust. give it some welly and this then clears. then coolant level warning comes on. car will be fine for a day or so and then the same again. i suspect i have an internal coolant leak on the egr valve. has anyone experienced this or know of a common fault that would cause these symptoms? cheers.

car all sorted now after adding a simple bottle of K SEAL. brilliant stuff.

after doing a combustion gas detector test, it is giving a positive result for possible head gasket leak.

i feel that in my case it was not a good idea. I have used a draper expert combustion gas detector kit borrowed from a friend. an easy to use piece of kit, but it's telling me i have combustion gases getting into coolant system. which is telling me a possible head gasket problem. i am now thinking that a previous owner may have used an additive to cure a head gasket leak and then me flushing the engine has removed tha additive repair.

tried a cap from a vw golf that runs fine. i have still got the problem and the golf ran fine with my cap on.

prongs are clean. level does drop but comes back up when i release the pressure by undoing the cap.

hi i own a 2010 (60plate) octavia vrs tdi. which has done 80,000 miles, but the coolant level warning keeps coming on. if i take expansion bottle cap off to release the pressure the coolant level comes back up. after a few miles driving it happens again . temperature does not rise above 90 and it's not boiling up. the oil is clear of sludge and i cannot see any leaks. i only did an engine service on 8th Sept and have had this problem ever since. i did not do anything to the coolant system when servicing the engine. engine oil flush, then oil and filter changed 5w 30 fully synthetic, new fuel filter and air filter. surely it's only coincidental that i have this coolant problem. anyone experienced this or knows of a common reason for it.

i'm hoping not. that's the worst case cenario. i've just jacked up the expansion bottle side of the car a high as possible to see if it's an airlock in the system to try and bleed it out. i'll keep you posted.

any idea where these bleed valves are? i'm getting the same problem with my 2010 vrs tdi (60 plate) which has just clocked up 80,0000 miles.

problem sorted! when the dumb ass mechanic changed the cambelt they put the 2 fuel lines on back to front. to be fare i'm just glad it was not a problem with anything on the car, but still took 9 days and the skoda top technician to sort it!

guess what? car not back yesterday as promised!!! now the salesman is telling me that the Skoda dealer is still not happy with hesitation and they are looking at the injectors now. i've owned a car for 8 days and only had it for 20 minutes. i'm now starting to get fed up!!!
