Metering Unit Replacement - HELP !!!!!
 

My tame mechanic has advised me that my 'delicate' metering unit has now had it's last 'tweak' and that I should seek a replacement.

0438 100 125 is the Bosch part number that I can identify.

In the absence of a direct numeric match, what are my options ?

She's off the road at the moment because she simply won't idle and all attempts to re-animate her have failed. :sad:

Refurbishment?

There are a few threads recently, dealing with K-jet oriented injection, with metering head problems.

You don't mention what vehicle, or symptoms.
There's many a 'tame' mechanic foxed by older injection, and several have suggested expensive replacement parts where some system knowledge and diagnosis has been needed.

I've some good kv metering heads I bought from booty a while back if you need one
PPC magazine has run features about k jet a few issues back
Interesting read and shows how basic and simple they are once you get to looking properly

I have 1 matching the numbers which I removed fully working at the time

Am in discussion with a senior member regards a potential replacement.

Please, everybody, don't rule me out for any advice, etc. just yet.

Thanks - you may hear from me regards this.

Thanks - your matching part number is of HUGE interest.

Hopefully, your donor part will bring new life to my 31-year-old - thanks !

It might be time to discuss one of your metering heads (if suitable). My (hoped for) replacement part from another member has not materialised.
