Hi all.

I feel like I've bought a story car but here goes my next problem and hope you can help.

I have recently bought a 2008 Skoda Octavia 2.0 TDI manual. Last night on my way home from work I lost a whole load of power especially going uphills. On the flat it wasn't as bad. No engine warning lights, gears were fine smooth, clutch was fine, engine was still relatively smooth. I could rev it to the red line which suggested it wasn't limp mode. The turbo however didn't seem like it was kicking in properly. Overall it drove fine but it really died going up hill.

Does anyone know what this could be?

Thank you.

Could be a sensor or something but it really needs plugging in to check for fault codes.

Vacuum pipe to turbocharger actuator degraded and collapsing under heat load, if you cycle the ignition it will probably pick up the boost only to lose it again if its a long steep hill, it will be much worse when laden, towing and/or in hot conditions.

 

If it only happens within the first few miles during the warm up phase then its clagged up vanes/actuator and needs a Mr Muscle enema, give it one anyway to show it who is boss!

Thanks both. It started doing this from cold. Just taken it to the garage tonight and it drove fine on the way there so who only knows what's going on with it. As ruffday says probably needs a scan. I've heard these talks about Mr Muscle, nooo, just nooo. Not right, recipe for disaster.

Mr Muscle in the turbo works great for a cheap fix to free up the VNT vanes!!

Started from cold this time of year and during the warm up = sticky vanes = Mr Muscle enema time.

 

On my MK1 I could delay the treatment a few years by always driving gently during the warm up period in the winter months and cycling the ignition when it did happen.

 

Recipe for disaster, for the garages losing the gift horse maybe, my car when I got it at 188K had already had two turbos replaced at a cost of several thousand pounds and was once again exhibiting the same fault which is why it was sold, I put up with it for a few winters as I had found how to overcome it but had not diagnosed the problem, when I did I gave it an enema and had to do so every 2 or 3 years.

 

I took the car up to 500K miles during which time the garages would have fitted probably 4 more turbos, I'm convinced the original one could have remained on the vehicle for its life but for their greed.

 

During that mileage I saw many French friends paying out on average €3.5K a pop to have their VV turbos replaced needlessly, now they have found an even more lucrative market with DPF replacements.

 

Its your choice, you have the info now, bet you change your tune when the garage give you the estimate.
