Just been driving up the road when, whilst in fifth gear, it stopped wanting to pull, power was way down but would maintain the speed I was at. All guages were reading ok and no warning lights on. I pull off the bypass into some smaller roads and the car seems to be pulling through the gears fine, so back onto the bypass. I take it through the gears, changing at about 6k, when the problem occurs again, this time the temp guage soars into the red and the red temp warning light flashes and beeps at me. I pulled over, and strangley within about 10 seconds the temp returned to normal temp (always seems to be bang in the middle of the temp guage when normal running, regardless of how 'enthusiastically' it's driven). SKODA dealer is round the corner so I pop in and he plugs the little box of his into the diagnostic port, which tells him that no fault has been found or recorded. After some discussion I take it up the road when the same happens again, so back to SKODA where I have now left it in their hands. Still under warrantly so they better sort it out, but they can't look into it 'till it's cooled right down. I thought the ECU would record any faults or blips, but apparently not.

I'm awaiting the call from SKODA with their diagnosis..... :confused:

Oh and yes the water and oil levels were ok, and the car's an Octy vRS '03.

What engine is it?

What engine is it?

bog standard vRS Octy

(at the moment...)

Presumably no physical signs of overheating apart from the gauge reading and warning light? Temperature sensor problem?

I had temp sensor problem even though the temp was clearly ok...no problems with driveability.

Heat does have an affect on performance.....on high ambient temp days boost isn't held as well....backed off due to high inlet air temps I guess.

well, still awaiting call from garage.

The lack of power was rather dramatic because the car would not reach 100mph, which normally as you know is no problem. However, it raced up still through the first 3 gears until the 'power problem' kicked in.

maybe as you say, this was due to the temp, but bearing in mind that the power loss occurred before the temp rise and warning light kicked in. still, sure I'll get an answer from skoda soon......... :(

I would hope that the ECU would reduce engine power to minimise the possibility of damage in the event of the engine overheating. If the temperature sensor is malfunctioning and sending a signal to the ECU indicating overheating, the same should happen. When a temperature sensor played up on my Felicia, the ECU thought that the engine was warm when in fact it was cold. So the fuelling was wrong and the engine wouldn't idle until warm.

I may be on a bit of a limb, but it may be the water pump failing (if the engine is actually overheating). When it happened to mine, I could get up to speed until it overheated (which wasn't long) then if I stopped the temp would drop very quickly to normal.

(see avatar for my water pump!)

I'd agree with that, id put money on the impellor has come off the back of the water pump, need to check the return back to the header tank for good flow, bet it aint.

Just had a reread of this thread. Can I change my mind? :(

This is exactly down to the nail same problem i had a month ago,same symptoms as yours turn out to be the fins on the water pump sheered off.

just phoned skoda dealer back, the technician is still trying to find the problem....

I did mention the water pump, cheers guys, the service guy said he'd pass it on and bear it in mind, but I will be getting a call "just before 5" withthe diagnosis.

Will post the result.

Just had a reread of this[/url'] thread. Can I change my mind? :(

of course

I'm not sure if the newer pumps have plastic or metal impellors. I did read somewhere (can't find the thread at the moment) about an uprated pump you can buy... Piv34UK... over to you phil

found the link... here (looks like AMD may know where to get them)

well... just had the phone call from SKODA dealer...

it was indeed the impeller/impellers on the water pump. you clever bunch :handshke: . the dealer was surprised because the loss of power and overheat was not constantly there. anyway, just a case now of waiting 'till they can fit it in to be fixed, or i'll be asking for a courtesy car.

good to hear that the problem has been found

I had this problem..... (search the site for Error code 17704). Whilst on a long journey doing constant 55mph in frosty conditions, I turned onto a dual carriageway, and accelerated to approx. 70mph, when temp light, buzzer and STOP lights all went nuts, and temp needle soared into the red.

The car was taken away and apparently the problem originated in the thermostat, and caused the water pump to eat itself. Later that year, the expansion bottle & level sensor were replaced also.

My advice.... start at the thermostat. Th ediagnostics should throw up error code 17704 if its the same problem.

D'oh!!

Too slow.... glad it's sorted.

Got my baby back today, the diagnosis was correct, the work was all covered under warranty :yipee:

The wording on the invoice is...

Inspect for irratic temperature guage readings inspect and 1552-no fault found - Inspect found water pump impellor cracked and adrift of pump shaft - also damage to thermostat - replace.

What did bother me though was that apparently the new one fitted also has plastic impellors, they say Skoda only do the plastic version. When I asked how long this new part was covered, I wa told only for as long as until my warranty expires. Does this mean I'll be shelling out for a new one in another 28k miles? :jawsmall:

At least I'm mobile again. So far, my warranty has covered TWO incidents of replaced Coil Pack and this replaced Water Pump and Thermostat. Thank heavens I put the re-map on hold, or no doubt they would not have been covered!
