Bosch pump
#1
How can I tell what's been done?

Got a new pump on, coals like a bitch and is so uneconomical it's unreal, looks like it might have something lda done. As the bolts have been tampered with.

Fueling is really bad with it. And cars really sluggish. Over fueling?

I had this when I fitted the 11mm....

My bet would be two things...too much max fuel and the LDA internal wheel being wound out too much.

as soon as I wound it in a bit I got my smooth power delivery back...only takes a few min to whip the top off and check the LDA pin and setting

Just the ufo bit dude.
Pull the rubber diaphragm out thats attatched to the lda and youll see a white cog.

well....mine was grey but its clear as day...I wouldnt pull at the diaphram though...get a level of somesort under the diaphram to something bit tougher to pop it up...

worth checking the LDA is facing right way too!!!

remove the top 4 bolts. gently lift up the top and move to side.

Have cloth handy...maybe some oil residue.

get a wide screwdriver or decent lever, lift the diaphram with ya finger and get the lever under to gently lift the LDA pin up and out.

You will then see before you a loose spring sat in a recess, the recess is part of the wheel you need to turn.

standard is about two threads showing IIRC.

I found my 11mm pump to have none visible...after some fiddling, its now wound in till about one thread is visible.
Wishes for more power...
