Bought a second hand Skoda Octavia 2.0 TDi 3 months ago, 2009 reg

It now has 57 k on the clock.

On sunday it seemed to lose power when i was driving. In 4th with my foot down and revs up to 3000 struggled to get to 60 MPH

Yesterday seemed fine foot down and it just flew today same problem in 3rd gear high revs struggled to get to 30 mph.

Booked it into a garage but mechanic has no idea of the problem without doing any diagnostics on friday.

Anyone got any ideas or knows if skoda tdis have a particular problem

Also No warning lights on the dashboard indicating anything.

any advice or questions to ask appreciated

From the limited info given it sounds like the turbo vanes problem that Octavia's are known for. When accelerating up to 3000rpm, when turbo is giving max boost, the turbo vanes stick open, causing an overboost. This results in engine going into "safe" mode, and thus the engine will have very little power as its effectivly running without a turbo. Restarting the engine allows the ecu to reset, bringing back full performance until the next time the vanes jam open, then its back to limp home safe mode. Its caused by a build up of soot/carbon in the turbo, usually when the turbo hasn't been used much, so cars that have been used for urban driving are most likely to be affected. Can be repaired quite easily and relatively cheaply by any competent mechanic.

Do you know whether other Skodas have a similar issue or is it just Octavias? We acquired a Yeti a short while ago. It's so good I am thinking of getting another Skoda when we come to replace our other car.

My dad has a 2010 Skoda Superb 2.0 diesel, approx 60k, had no problems whatsoever yet. Other than an annoying Sat Nav!
Unless something disastrous happens to this one in the next few years I think he's now a fully paid up member of the Skoda fan club!
