WOULD A Inlet Manifold & egr valve OFF A 1.9 115BHP MK4 GOLF TDI (fit ?)
ON A 1.9 90BHP MK4 TDI THANKS

Yes,

There shouldn't be any issues with the EGR valve (045.131.501.C).

Likewise, for the AGR and manual transmission ALH (not automatic ALH) 90 BHP TDI engines, the AJM/AUY 115 BHP intake manifolds would also fit (038.129.713.J).

So to summarise, cross check your engine code and there shouldn't be any issues providing you have a manual transmission.

As a straight performance enhancement, NO, you will not see any power improvement, since (as mentioned) the parts are equivalent.

However, if your

• EGR valve is sticking and not closing properly
• Intake manifold is significantly clogged with soot/carbon/"gunk"

Then in these cases airflow will be restricted (engine breathing difficulty), so indirectly performance will suffer. Installing a properly functioning EGR valve and a "clean" intake manifold may help.

You can check for engine breathing issues such as the above, either using measuring blocks in VAGCOM/VCDS software or by disconnecting the boost hose from the EGR and ensuring the EGR valve is closed when the engine is off, or applying a strong vaccuum to the EGR valve to verify functionality.
