MAF and poor running help.

buckingthetrend · Mar 17, 2019

Hi guys.

Iv got an 04 Td4 that is running rough. I had thought injectors at first but now I'm thinking MAF. It seems to have an aftermarket MAF and I think it is in the wrong place (between the intercooler and EGR) could this cause a miss fire at certain RPMs?

Also I found a worrying Blob of metal filled oil under the MAF but found no more elsewhere in the system. Has anyone seen this before?

Thanks

That's the boosted air intake temperature sensor. It's normally in black plastic housing, but otherwise it should be there.

OK. Tha ks for letting me know Where should the MAF be then?

The MAF is on the turbo side of the air filter. It's visible once the air filter cover is removed.

OK. Have you got any thoughts on the metal filled oil found arround it? Cheers

Any metallic particles found in the intake can only come from 1 place, the turbo.
