110TDi - power problems (continued)

[mbames]

Right then... visited the local Skoda place on Saturday.

Fault: intermittent lack of power (once hitting about 3200rpm, especially under load).

They initially suggested the MAF, until I reminded them they had replaced it a few months earlier to cure the same problem. They ran a full diagnostics, and did not really come up with anything, so they suggested changing the (n75 valve?) - some white topped valve on the passenger side of the bulkhead, but typically they had no stock. They want to sell this to me for £25, plus another £20 for labour. I reminded him I had already bought a MAF which appeared to be a wasted purchase as it had not cured the problem, so they are going to fit for free *next* monday.

Ironically enough the car was fine this morning (cooler, damp), but was useless over the weekend (hot and sunny). Not sure if temperature has any direct relation... will keep an eye on it over the next week.

i think the N75 would probably throw up an error?
i would buy it and change it yourself, its easy to unplug and swap over

I used to have a problem like this with my old lancia thema turbo..... it turned out, after alot of searching, that one of the hoses comming from the intercooler was cracked! impossible to see unless you bent the pipe, but was letting boost pressure out under load..... a new pipe for £15 fixed it!

Could well be the N75, if it isnt I suspect a sticking turbo.

Both however should throw up an overboost fault.

And just because they changed an air mass meter a few months back doesnt mean it isnt faulty again, they really are that reliable. But if they fitted the part they should have 12 months parts warranty on it anyhow.

Hi,

I exerienced a similar problem with my TDi 110 earlier this year, luckily mine is under warranty but it had several items replaced from the MAF to the ECU all without success, eventually it turned out to be a dodgy Turbo although the ECU did not report a total failure of the turbo.

I would find that at certain RPM's depending on gear there would a slight stutter and then no power at all until I had stopped/started the engine, then it would be fine again until I hit the rev band and it shut down again.

It took a long time to diagnose the problem (between Feb and July) as it was a case of trial and elimination to get to the faulty part. I did poet the problem here but it seemd to have been removed from the Forum.

If the valve thingy doesn't cure it check the Turbo next rather than waste more money on parts you may not need.

Hope this helps
