Fault Codes AUDI A4 2.0 TDI

[VAG]

Hi There was driving my car today when the glow plug light started flashing so took it to local garage who put it on Diagnostic machine and these are the fault codes that have come up

Car is A 2007 Audi A4 2.0 TDi 170 BRD

01025 EGR System insufficient Flow P0401 Short With Power intermittent
05214 Mass Air Flow during Regeneration too Low P145E Short With Power intermittent
12546 Motor For Intake Manifold Flap (V157) No Signal P3102 Short With Power intermittent

The top two Fault Codes the garage could clear but last one wouldn't Any idea what it can be

Thanks In Advance

Thanks for the reply can these two codes be related as a brand new EGR was fitted About three Months ago

Check the 15 amp fuse in the plenum chamber water box first.

Thanks Crasher for replying just wanted to know where the fuse box is located can't seem to find it

[Crasher]

The big plastic box under the windscreen that has a stupid buried screw at the back which means having to take off the wipers and scuttle trim to get at it.

Hi Crasher just checked the two fuses in ECU box and both seem fine below is a pic of where the fuses where just to make sure I checked the right ones
18893
Thanks

They are the correct two fuses. Do these codes you listed clear and come back immediately or do they take a while to come back?

Thanks Again Crasher The intake manifold flap code will not clear but the EGR insufficient flow clears but returns after a while and the MAF code has not returned yet

Have a new V157 manifold flap fitted and go from there.

Hi Just received the new manifold flap which has come with a sticker saying that it needs to be programmed/updated just wanted to know if that is necessary and if yes how is it done
Thanks Again

[Crasher]

Not that I am aware of and no mention on ELSA and I have never seen it on VAS PC for the V157.

Hi There just to update been over a month after fitting new inlet manifold flap and also EGR was replaced under warranty and car has been good since then
Thanks again Crasher for all your help
