Guys,

my car's been giving me jip lately. I'll be driving along and then when I go over 2000rpm it will struggle to get to 2500rpm.

Pull over switch off engine, restart. Everything's back to normal and full power is available.

Now it does it quite often now, I drive 60miles for work daily, and it will pretty much do it a few miles into the journey from cold. Once I restart it, it's fine.

I'm thinking it's something to do with the MAF - is this correct?

There are no warning lights, and i recently had it scanned for faults and it only came up with the stupid heater flap motor thing (the thing that messes up the cold air into the cabin) which Skoda didn't replace for me.

Since there are no other fault codes, I'm thinking it's possibly the MAF.

What do you guys think in your experience?

Ps. it's a 100bhp tdi, so it doesn't have a variable vane turbo.

Not an expert at all but when you put your foot down when this happens does the engine sound different e.g deeper tone?

its obviously goin into limp mode...you need to scan to see wot fault codes it throws up

Its the actuator sticking in the turbo i m afraid, no cure but to strip and re build or replace turbo

Is this the variable vane thing that is common to the 130bhp VW engines?

PD100 turbo is also variable vane, just a bit smaller than the PD130 ones.

Brian.

Yes, as devonutopia says its a vnt unit just like the 130..... and fails just like the 130, we always fit garrett units now as the kkk's are made of cheese and ice cream

Thanks for the replies guys.

So it's all pointing to be sticky actuator or sticking vanes inside the turbo?

If this is the case, I've read that people have used the INNOTEC turbo cleaner to various degrees of success. Would this be of use for me and my 100bhp ATD engine?

It's also worth asking, does a sticking Actuator throw up fault codes? I've had my car scanned numerous times, and it's never shown up a code relating to engine stuff (it's only ever shown me errors relating to the heater motor flaps not working for the interior ventilation). Should a fault be popping up when scanned for the above?

Is it worth trying the INNOTEC turbo cleaner stuff first?

And on the other hand, how much would rebuilding or replacing a turbo for this car cost me?

It should do really. When the actuator sticks it usually causes overboost, i.e too much boost being given, and the car will go into limp mode like it is doing for you, and the fault code is usually along the lines of "thrust sensor [This is techie name for boost sensor] positive deviation" i.e it has asked for XX boost but has seen XX+ a %% more boost, so it kills the turbo boost all together (limp mode) to protect the car. For people with no boost gauge (i,e all stock cars) I think this is a valuable fail safe function.
