For All people who have had to have their Turbo cleaned!

[bombheads12]

please could you place your vehicle details in here, reason for doing so? well I am considering contacting the manufacturer to state a complaint via watchdog (who ever) as i believe there is an underlying design fault on the Leon MK1 and possible MK2 as i know particulate filters are placed on the newer model in order to stop Turbos gunging up. p.s. the filters are a nice £1000 each and there are two!
So come on please lets see how big this problem really is, I also believe its a manufacturing defect as in no teflon surfaces we shall see eh?
Thanks In Advance

mine for starters is a 52 reg 2003 110bhp asv SE model only just coverd 50600 miles and already needs a clean not on!

I thought particulate filters are placed in the exhaust system to help combat the amount of soot created by the bigger diesel engines. Therefore it wouldnt effect the turbo what so ever, you just need to give your car a good thrashing now and again to help burn off the carbon that may accumalate within the turbo.

Ptar.

i thought DPF is just a recent thing on new models. yours will just be a cat converter.

 

[Muttley]

Particulate filters are there to comply with the more stringent environmental legislation that applies to later models.

They are after the turbo and will make no difference to soot deposits on the variable vane mechanism.

you should do some more research before contacting anyone & potentially making yourself look very ignorent of how the thing functions in the first place.

As people have pointed out, your understanding of everything mentioned in your post is flawed. I would hold fire on your letter and maybe get new sources of information.

So enlighten me? this is one of the quietest forums for a vehicle make that i have used in a long time lets get the ball rolling
my first question is?
why should a turbo need cleaning after 50,000 miles! you say i am flawed ?? it was the service manager that told me particulate filters were fitted to new Seats and he showed me the bill for replacing them £1550, and i said i was considering contacting the manufacturer as a potential problem but with only my response I am hardly going to have much evidence eh? im not that daft
but so far as i know that leaves as a probable cause inefficent burning of the fuel by the combustion process leading to too much carbon being buitl up, before you ask yes i am a mechanic of 20 years experience before moving onto aero gas turbine engines
so fire away with the answers
please

Out of interest, which side of the turbo needed cleaning - hot, cold or both?

Forgive me for pointing it out, but you seem to have a smidge of an attitude going on, which isn't endearing people to you. We're not SEAT but it feels a little bit like you're blaming us for a problem with your car.

 

[andycupra]

ive been active onthis forum for a good few years and i am not aware of any common or near common issues with turbos needing cleaning.
many on here run remapped cars and still have no issues.

I cant comment on the newer MKII cars, although i have seen a fair few posts moaning about DPFs... however ill say no more as i dont have a complete understanding of the issue.

Nah sorry for coming across like an attitude, I am purely asking people do they have problems? yes mine is having its turbo cleaned after 50,000 miles, and yes i believe its the hot side, and i believe its to do with the vane actuating mechanism getting clogged with soot (carbon) due to not enough gap between operating vane and housing.
I am not blaming anyone here for the problem,lol I am purely stating that if this is a well know (trade problem) with this turbo the Garrett VNT15 i believe then why has there not been a product recall/replacement?
Do you think SEAT could sell their vehicles if it were known that every 50,000 miles you had to fork out for a turbo clean the average motorist would Sh*t himself at the thought of it! lol

You know how it goes - if it's not a dangerous problem then there won't be a recall.

Same as the problems with the particulate filters on the Mk2 - it seems to be something that owners are just having to put up with.

 

[bombheads12]

Yes true MarkE
cheers for the reply gotta run beers on the table in the pub! lol
take care have fun

 

[CupraMVR]

I know we hav had a few cars in with this problem with the turbos glogging up with soot. but its not only on the leons its on all PD engines causing the problems, we normally take the turbo off clean them and refit.

its just the time to take the turbo off and refit, that the money is involved and a few gaskets.

 

[bombheads12]

Thanks for replying CupraMVR i presume you are a garage? so maybe you could answer my question why do they need cleaning at such an early age and then how often do they come back as in clean at 50,000 and return at say 100,000 or do you advise a cleaner bunged down through the system? my reason for asking this question is quite obvious .
As Time goes by the parts will dissapear oh and by the way mines not a PD lump as mine is the 110bhp VEP i think tho god knows what VEP is lol

7 year old car
50+ thousand miles

and this is a warranty thing in your mind yea?

the service manager is as ignorent of how it works as you I'm afraid.
diesel = soot.. unless you have something else injected to burn off the byproduct soot

VNT's will clag up in use...

I think you have zero hope of getting anywhere with this..
good luck tho

 

[bombheads12]

okay so do you know how often they should be cleaned ? as in #14 ?? or would it be better getting a different turbo fitted? and on a side note i do not expect a warranty repair, and i do appreciate soot all i am saying is there is an inherrent problem with vane turbos if they need cleaning every 50,000 miles as most turbo diesels i have had do not suffer from turbo cleaning every 50,000 miles thats what i am trying to say

 

[CupraMVR]

I think its a bad design on the VNT unit on these turbo's, there is not a service advise on the units but we have done a few at work.
I work at awesome gti in manchester, so we know about the problem with the turbo's but its the same on VAG group cars

 

[Muttley]

It will depend entirely on how it has been driven. If the car has only been used to potter around town at low speeds and/or has been driven by a fanatical economy-measure driver then the turbo will never have got hot and the soot will have accumulated. In normal mixed driving, with a measure of motorway-speed cruising, the turbo will have got up to its expected temperature and burned the soot off.

The majority of the soot in a modern diesel is generated by the action of the EGR system, operating to reduce NOx emissions. If your driving happens to coincide with the performance areas where EGR is active then you will soot up sooner rather than later.

How do you know that the turbo needs cleaning? What symptoms is the car showing and who has told you that cleaning the turbo will fix them?
