Hi
I have seen some info on turbo failures, and wondered if my issue was related - if anyone can shed some light please?
I had 2 instances where my car went into 'Limp home mode' - which I had no idea exsisted before then, forst was a short journet and it just seemed like there was no turbo the car just wasn't pulling.
But when I got in it the next day it ws fine, the second I was on the motorway doing about 85 when it lurched slightly and lost all turbo it was as though it could barely drive, again it got me to the airport and when I returned it drove okay. I took it to a local garage (not Skoda) they put it on the computer and I got the fault code: 00564 Boost Pressure Regulation Limit Exceeded (Overboost Condition) P0234 Intermittent.
It had happened twice in a week and I was driving it pretty hard at that time, I have driven it like a baby since and it hasn't re-occurred?
The garage reckon it could be an electrical fault like one of the sensors (which I had on my Mk1 Octavia.
Anyone else had this, was it a sensor that caused the problem?
Many thanks
Rob

It sounds like the dreaded " stuck vanes in the Turbo" problem. You will find that you can poodle around like Ms Daisy ( >2000rpm) but as soon as the engine needs to boost itself up some Torque, it will slip into Limp mode. Its a fairly common problem with the Turbo on your car ( GT1749 ). There are posts on here showing how to take the Turbo apart and sort the problem but unless your a mechanic I would say it would be more cost effective to replace the Turbo before it completely fails and does possible heafty damage to your engine. There is also a post mentioning a cleaning treatment which looks like it could work to de-cake the vanes of the turbo if you do a search here and on ebay " innotec turbo cleaner ". If you need to replace the Turbo, I can't recommend Turbo Technics enough. Get it to a VAG specialist first to diagnos the problem............................Best of luck with it.

agree with the above

turbo's can be cleaned if you find the right person instead of replacing the unit it just easier for a garage to replace turbo

try the cleaning first if that fails find a turbo specalist and see what they say :thumbup:

Yes, almost certainly the turbo I had the exact same problem. Dont pay more than £600 for a recon unit fitted. Its not a huge job for a garage who knows what they are doing.

BTW, as a matter of interest, are on fixed or variable servicing?

Same here, I had a few overboost conditions then the turbo went bang spectacularly (turbo casing split in two) which cost a fortune as it threw shrapnel all around the intake system, even managed to pierce the intercooler!

I told the dealer about it and they said it was a nuisance fault and not worth worrying about. Lucky it was just inside the warranty period.

You have been warned, get it looked at ASAP.

Before the overboosts I would sometimes get a high pitch scream/whine from the turbo not dissimilar to a jet engine. It also felt like I was driving along with the handbrake pulled up. Once I lifted off and put my foot down again all was well. Sticky turbo vanes - another quality aspect of the 2.0TDI engine :thumbdown:

Hi All

Many thanks to you all for your replies and help, I will try the cleaning first, as this happened first in November, (twice) and hasn't re-occurred I do drive over 2000 revs on motorways etc, but not often do I thrash it these days as the cost of deisel is getting silly :o)
Not sure that I will be up for stripping down the turbo to clean it unless it is a fairly straght forward job (haven't seen the posting).

Westallc - Not sure what Remapped is so I guess not.

Stacon - re servicing I just get it done when the indicator calls for it, approx every 20K miles..?

As I said, my local not Skoda garage said it is probably electrical, I know there is a sensor on the air intake which went on my Mk 1 Occy , but you guys seem to be pretty confident its the actual turbo so I'll go with that.
It is out of warranty sadly, just over 3 years old and 58K miles on the clock, I guess I should look at getting this replaced along with the cam belt - an expensive few months ahead then I guess.

Cheers All
Rob

As it is only just out of warranty and has fairly low mileage, I would look for some goodwill from Skoda, as this is a very common complaint. Does the car have a fairly solid service history ??

Yes it has been serviced regularly, but I think my warranty was only 2 years as it was a European parrallel import, i.e. I bought it from a UK dealer who bought it UK spec from Europe, so I got a 2 year warranty instead of 3 years, also I live in Northampton and the Northampton Skoda dealer has recently gone bust so there is no Skoda dealer locally mearest is Bedford I believe, so I don't think this will help to be honest?
Thanks
Rob

I wouldn't let it go. Its still a Skoda regardless of where it came from. I would still try to find out where it came from ( what country ) and chase it up there or go to a UK Skoda dealer and try it through them, if they get the go ahead on warranty its a paying job for them in these lean economic times. Its very low mileage for a turbo to go. This is such a common fault I would nearly argue that the garrett turbo is not fit for purpose. ( clutching at straws I know ).

I have just run Vagcom on my wife's Octy 2. The car is 3 years old with only 30k genuine on the clock. - I have serviced every 10k myself using approved engine oil. - I would not pay the ridiculous amount my local dealer wants for servicing. I have the P0234-000 fault code (Overboost) after the car went into limp mode about a week ago. - I was driving the car pretty hard at the time. - I pulled over turned off for about two minutes and all has been fine since. - Surely the Turbo can't be om it's way out with only 30k on the clock? - I will try some Turbo cleaner anyway.

Get it diagnosed asap, its unlikely at this stage but if the turbo fails as others have said it can cause major problems. When mine finally died on the Odty 1 it went up the road doing a passable impression of a red arrow, clouds & clouds of smoke.
If it starts smoking stop asap. the smoke is coming from burning engine oil which a diesel can run on. If you are really unlucky it will dump massive amonts of oil into the car & the engine will just rev & rev until it goes bang, the imiter wont work as all that does its cuts off the diesel supply but if its running on engine oil it just revs higher & higher. If you get this problem & you cant stall the car on the brakes the only way of stopping it is to block the exhaust & hopefully strangle it that way. (carry a potato maybe) Ive heard of one person, a mechanic who could not stall the car, had to declutch to stop quickly & it went bang
