Hello,

I have a grey 2010 1.6 Diesel Polo. It doesn’t drive but it starts. I have been told by a friend who’s a mechanic it’s a possible filter issue, but they’re not 100%.

Would it be worth investigating to try and get it fixed, or am I best selling for parts?

If best selling for parts, what would be the best way to go about it?

It’s in average condition, usual wear and tear. Never been in any crashes or written off.

When it was driving, there seemed to be an issue with acceleration. If the revs went too high, the engine slowed down and it would need restarted. I was told it wouldn’t be worth trying to fix it.

Any advice would be appreciated! Thank you.

Does it start normally. or struggle to start?

I'm guessing he's thinking the filter housing is pulling air through a split or a bad seal. I'd be tempted to bypass it with a bit of hose for diagnostic purposes and see what happens.

The engine going into limp mode if you've been pushing a bit hard. normally without throwing an engine light, is typical of the variable vanes on the turbo getting stuck, although i can also be the EGR sticking. There's various ways of doing a DIY clean on the turbo and EGR using Mr muscle oven cleaner. I've not done it on a 1.6, but there should be a few videos on youtube.
