Multivan losing power?

[shogun2]

Hi all,

The Multivans' in the shop for some wok on the sat nav and doors. In the mean time the dealer has lent us a 77Kw TDI Transporter. What I have noticed is that there is significantly more "go" in the Transporter with the lower powered donk than there is in my 2005 128Kw TDI.
Is there anything I should be looking at that may be slowing down the response of the Multivan? It just seems sluggish in comparison.

The Mulitvan is somewhat heavier, so bare that in mind.

Does your Multivan have the AXE engine in it? If so, it might have a cracked exhaust manifold.

Are the AXE engines prone to have cracked manifolds more than other engines?

How do I find out what engine the MV has in it? It's a 2005 version.

Inside the service book there's a sticker. The engine code is on that.
I am thinking it might be a MAF.

Is yours auto and the loan one a manual?

[shogun2]

No - both manual.
Gavin, what's a MAF?

OK - just googled it - Masss Air Flow sensor! How would this affect the performance? How would I ask the dealer to check it?

I am with cracked exhaust Manifold....

Have you had issues with exhaust fumes in the cabin?

No - both manual.

The MAF measures airflow but if they fail it'll still run, just not as well. Does it feel to be actually down on power, do you remember a time when it went much better??

VAG-COM can read the MAF and tell if it has quit.

I think it has been a lot more responsive before, but it's been five years since it was new, so it is a bit had to remember. Should I ask the dealer to run vagcom and look for error messages while they have it?
