hi all,reporting back from the garage.did nothing to it apart from topping up differential fluid and replacing air filter.as i suspected the noise is still there,except louder that now im able to properly discern the noise pattern.or maybe just because i had the radio off and no kids.i was mistaken.it was not constant.it follows the wheel speed.and it's most likely mechanical.please see the recordings; https://youtu.be/C5tzI9l7BHs https://youtu.be/1L84nnOzGkY err..embedding youtube,am i doing it right? my mechanic said it's likely the gearbox final drive gear.i believed him.but on the drive back,my suspicion arose.that may not be the case judging from the noise that's seem to be originating from the right side instead of the middle.and no clunking during start stop traffic jam.i figured if the final drive gear is knackered,that's when the noise should appear because that's the initial point the engine torque gets transferred,and that's a hell of a stress to a bad gear.or maybe im just biased since i really don't want to part the gearbox

KenONeill was right. that's not the kind of noise im having.i have a strong feeling that it has direct effect from the turbo spooling

i'll start off by cleaning the airfilter.my logic says since it only happens when the turbo kicks in, thus huge increase of demand for air more than what can pass thru the clogged filter hence weird stuff happens.it's about time anyway.

thanks for that. the noise is related to engine speed, and load.light throttle doesn't produce that noise.seems something to do with turbo, air gong in.usual symptoms i found on the net related to N75, 710N valve, coil, they don't match with what im seeing with my car,as far as my observation skill is concerned

recently, my 1.8t auto started making this noise, i'm not quite able to describe it perfectly but my best is gluk gluk gluk. when even my wife is able to notice it, surely it's there. whatever it is, the noise is pulsating at constant rate only under heavy/partly heavy acceleration. no noise at cruising speed. no noticable loss of power, or probably that's because i always back up the throttle a bit from fearing something might burst.i don't think that's highly likely but i prepared for the worst.the noise goes away when i do that. to help with diagnosing here's a list of info; -just did the coolant flange change (hoses were disconnected but inspected all seems to hv been put back in nice and tight) -replaced two cracked hoses on top of the turbo (i think they're breather hose or water hose of some sort) with generic non OEM hoses -topped up with g13 coolant instead of g12 (the only one i could find during that time frame) -no CEL -noise absent in 1st gear even when pushed hard -fuel consumption normal -temperature rock solid at 90 deg -differential is seeping oil,not seriously leaking tho -air filter hasn't been changed since the last 2 service intervals (1 year) -timing belt and water pump done at 150k km, now at 180k km i know im shooting at random here but i have yet to find time to send it for proper inspection so i guess these details might help u to help me and.always reassuring to have a heads up.

Oh that make sense.After much thinking,im going to give it a go ahead.hope nothing leaks after that

Pretty much leaves no space at the front wheel arch

Yes a 5 spd tip.with the engine,turbo and gearbox,it seems to me that the stock cooling system would have to handle too much.ill keep the stock cooling with additional oil cooler for insurance.its a very hot country reaching almost 40°c on midday plus the lazy slushbox that slips way too much doesn't help either

Couldn't find much info on this or precedent s for case study.maybe it's unnecessary?but i like the idea of preventive maintenance. Plus it's not that expensive. What's the thought on this fellow briskodarian?

My mech would advice for secondhand box for rm3k,that's about less than £600 with 6 mnth warranty. But if anything happens to my box beyond needing oil and filter change,i'd go for manual all the way

It'd never end huh?im doing cv boot replacement since its splattering grease all over.got the car up on a ramp and this caught my eye...is it bad?

Here's an update. The pas is working perfectly now.glad the fix worked

So i didn't go ahead and order original replacement. I thought there's got to be some other ways. Indeed there was.for less than €100 i got the hose refurbished by hydraulic specialist.Fitted nice and leak free.i strongly suggest anyone facing this problem to go down this route. but,here's the plot twist.during drive home after fitting the hose,occasionally the steering lost assistant for about a second and then comes back.air inside system? Pump going bad?

That would be easy if i live in the uk.finding another superb here,let alone someone i know,who would actually want to swap,i think I'll skip.what about 1 inch rubbers on the spring seats?

Im on h&r springs with stock shocks.it rides a little too low scraping all over speed bumps.bumps always catches the front part of the belly though so i guess giving a 1" lift at the front will do.but i have no idea how to go about doing it though,and cheaply as well.

I leave it without the pad for now.too lazy lately.it seems to be working acceptably fine after i fiddled with the sensor's positioning

thank a lot for the advice. It helps that i dont drive much these days.at least i can stand the long wait for shipment

Looked around for replacement and nobody has it.it has be shipped direct from Germany and thats for another 2 weeks.bloody hell.how is it so uncommon?it never breaks?well mine does.not to mention the price,€300,or myr1250 just for a hose.i could get a major service done with most expensive oil for that. Im going to a mechanic to have a look, probably just change some o-rings or patching up using heavy duty silicone or something.hope it'll hold up for another few thousand miles.do u think its a smart move or will it completely backfire?

Iob, the pic u posted shows a curved section at the end before the connection to the pump,mine is straight

Apparently its part no 10,isn't it?

is 3B1422893C number is the same with that on audi a4 and passat? do they interchangeable between these cars? im asking because most part shops in my country are not familiar with skoda, they'll go, what? no no don't have.but i'll get better chance if i mention audi

thanks for the visual.was really helpful.but,300 euro?really?does that even make sense? i'll give another proper inspection on where the leak actually is.

I think its this one then; 8D2422893BA

apparently the car survived. im looking to changing the hose. is this the correct part? part no. 1J0 422 893 DD. cant really tell from pictures. its should be the hose running from the pump towards the firewall. thanks for helping
