Question VVT Turbo problem HELP!!!

[lynneandcrow]

Hi there just a couple of quick turbo related questions. My car (AUQ 1.8t 2003) went into the garage today with the error code 16396 which is the vvt over retarded code . So the mechanic lifted the rocker cover off and all seemed fine with the vvt . He was going to take the sump off next but then moved onto the silicone hoses but noticed oil in one so he worked his way round to the intercooler and found that it was full of oil (fresh). So the turbo had gone great news. My questions are.

What turbo is it that is in the car is it a k03 or a K03s?

Could the turbo failing trigger this code?

Or has the sump filled with that much sludge that its done the turbo in?

Thanks

Id drop the sump and check the oil pickup pipe to make sure its not clogged, it can starve the engine of oil and blow your turbo.

And depending on engine code depends on the turbo IIRC, my AUQ has a K03s

K03s

if the turbo would be 'failing'?how exactly do you mean?
not boosting or boosting then dropping off or is there some smoke coming from the exhaust when the car has been sat at idle the turbo will start smoking blue ish fumes that what happened with mine,or another simple way to check if the turbo is on its way out is take off the turbo intake pipe and see if there is any play in the turbo, or in the intercooler normally can mean the turbo is leaking its seals?
sometimes owning cars like these it help if your handy with the spanners and want to look after the car imo.whats the mileage of the car as well, do you let the car warm up and cool down?if not this can destroy the life of a turbo

Thanks for the response to my problem.

There were no other symptoms to this issue other than hesitant boost from time to time but I recon that as I have been nursing the car all weekend tIll the garage opens it must have happened during that time this is why I have not noticed it. No there was no blue smoke on start up or whilst running The milage of my car is now aproaching 115k.

Now im looking for a turbo was looking at one for £210 which seems really cheap but have spoken to my mechanic and he says it sounds like a crap chinese copy not an authentic one and that i should steer clear.

Anyone know a good turbo specialist or retailer.


Turns out its a k03-052 turbo btw.

I've heard good things about http://www.turbotechnics.com/

No blue smoke though? Has the mechanic stripped the turbo off and checked it?

the VVt fault code points to a faulty VVT chain tensioner which has failed either through age (wear n tear) or lack of oil pressure normally due to a blocked oil pick up.

drop the sump and fit a new oil pick up and refill with fresh oil. wipe the codes clean if it comes back then the VVT tensioner needs replacing.

as for the oil in the intercooler pipes this is normal to a certain degree. the oil vapours in the crankcase get sucked though the breathers and back into the turbo intake pipe to be burnt off inside the engine. this causes oil to sit inside the boost hoses and intercooler/s. if there is a lot of oil inside then there would be cause for concern but I would imagine if it was as bad as your describing then your car should be smoking more than Dot cotton!

or the cheapest way 1st id guess is to check all the crank hoses are in all good nick if so then move on to what brad barker said about whipping off the stump and fit a new oil pick up pipe, then if not the chain tensioner as just mentioned, but I would of guessed if the pick up pipe was on its way out then the oil light would start flashing on and off ect,but then if its looked after then surely it wouldn't block up??im guessing.
a new turbo can be brought from aet turbos £420 re built that's how much it cost me, then all the other bits and bobs about £530 but that the last solution, and it would be smoking like dot cotton mostly at traffic lights and at idle

 

[lynneandcrow]

Thanks for all the responses there was no smoke but the turbo has been whipped off to a rebuilder/recon for a check and the turbo needs a complete rebuild. The other thing that is concerning me now is that my mech found shards of metal in the sump?? The oil pick up is goosed was not to badly blocked but there was defo a small blockage.

Looks like its going to be a hefty bill £400 for a recon turbo and then labour awch

 

[leegreenaway]

Jesus christ thats alot of dollar, you can usually get your original rebuilt for less the 200 quid! As long as the housing is sound....Sounds like cartridge/compression wheel in the turbo shredded!

Bad luck mate...i forked out 300 quid labour when my MK4 Golf GT TDi blew a few years ago and the garage screwed it up (never again!!!)...id recommend a braided oil feed pipe (or return pipe, its been a while since i fitted a turbo) too since the OEM ones are stuipdly expensive and a pain in the arse if the mechanic bends it on reinstall.

Not sure if this is a china copy but i believe it is a direct oem upgrade for the K03s, i read a thread somewhere on here

Yeah it looks like a chinese copy it has Toyo etched on it on a close up view of the picture. Cant remeber the actual real manufacturer of the k03 but im prety sure its not Toyo. Been on ebay and the net for ages today and authentic an ko3 would cost over 1k new recon 450+. Not going to risk it with a cheap turbo dont want to have to pay all the labour charges again.

Why are turbos so expensive?

 

[leegreenaway]

Never know...mate, i know people use the toyo intercoolers on here upto stage 2

There are some sellers from germany with the K04-001 too, id check to make sure they are borg ones though...itll be first on my list when i blow my turbo lol

 

[brad_barker12]

The k03 k03s and k04 turbos are all manufactured by KKK (borgwarner)

The fault code would only show if there was a fault with the Vvt tensioner. It wouldn't have anything to do with the breather pipes mate. Although it could be related to the oil within the intercooler pipework

 

[dazjstuart]

Just remember when asking for turbos and that, most people know what you mean but there is no such thing as a K03s! What everyone refers to as a K03s is a K03-052. The 052 bit is just the BW part number for a 180bhp version of their K03 turbo. There's a thread, think its on an Audi forum somewhere, where someone wrote to BW and got clarification on the matter.

Well hopefully all will be fixed when I get the car back tomorrow the mech is just going to put the drive shaft back on and the exhaust then that should be it done. Not too worried about the vvt now as it go's cos its a £80 recon part with an hours labour. After forking out 10x that its just a drop in the ocean but it has taught me a lesson! Dont ignore or reset fault codes that seem silly after all it was a £16 part the pick up pipe that has had a slight blockage and has cost me a fortune.

Thanks for all the help guys will update you when I get the car back on the road.
