Turbo Woes

[Ed1943]

Thanks doctordubs/crasher/zollaf but there's no way I'm able to remove and strip down the turbo. Took car out this afternoon, plenty of high revs and 2nd/3rd gear work for about 30 mins. Will this be sufficient to clear the soot or is it likely the problem will return (loss of power) or should I drive the car more energetically for the next week or so. Or does it mean turbo removal/cleaning or possibly replacement. As I said car has only 30,000 miles but it is 6 years old.

Drive.it spiritedly once a day just pulling through 2nd 3rd and a little in fourth for 3 or so days. After that it should be ok. I believe in giving a car little pulls through 2nd - 4th every so often. Keeps the passage ways clean lol.

VW garage refers to wastegate sticking but from reading other posts this is fitted to older type turbo's. Also when problem occurred there was no warning light or message.

Every turbo has a wastegate system. 2 main is the flap type and the vnt. Wat sticks is the vnt flaps and the ring connecting them to each other and the actuator

From the mountain of information on the Mk5 Forum from Zollaf and Co., with the fault code at PO234, it looks like a visit to my local garage (who are experienced with VAG vehicles) and get their views to possible removal of the turbo and either they can strip/clean or courier to a specialist. I've now had the car for just over 12 months but prior to this it had been run on long life service plan, but I have returned to the usual 12 months service intervals always assuming that clean oil is the life of the engine. Its still running reasonably ok but I'm nervous that a major disaster could be just around the corner (or over the hill!). Its great that all this information is available as otherwise you get sucked into VW main dealers and their high prices. They had quoted approx. £1500 to replace the turbo which they specified as a Garrett type 03G 253 014 FX. Assume this is stamped on the turbo. Will let you know result with local garage

After having a service + can turbo clean which didn't work have bit the bullet and replaced the turbo. Performance now returned and running smoothly (bliss). Managed to get my hands on a new turbo (not refurbished) and this together with fitting by experienced local garage resulted in costs being near to 50% of main dealer cost. Many thanks for all your help.
