Pierburg Manual Auto Differences

Post by WreckTangle » Sat Aug 22, 2020 3:52 pm

I am attempting to resurrect a Pierburg 2E2 to fit to my 1.8 GT2 Auto which is currently sporting a Weber fitted for a previous owner. Irrespective of the pros and cons of these rival carburettors my aim is to restore the car to stock.

I have got two units. One the, I believe, correct 027 129 015Q and the other 027 129 016H originally from a 1.6 but which had been fitted to a 1.8 Golf by the person from whom I acquired it. My plan is to strip down, clean and reassemble the 027 129 015Q and to use the other unit to replace any broken parts from the first. This is proving to be a sound strategy since the latter was recently removed from a working car and the one I want to reuse appears to have been stored for a while and consequently had some severely rusted screws some of which are not in the best condition.

There are a few subtle differences between these two units and I am trying to establish definitively the features that are different on cars with automatic transmission.

So far I have established that autos use a four point vacuum unit whereas manuals (without aircon) have a three point unit. This is indeed the case on my carbs.

There are references online to them using different “brackets”. I have yet to establish what this means.

I think the throttle levers are different. They are on the ones I’ve got. The manual transmission type appears to be as per the drawing (part 21) whereas the corresponding part for the auto is as pictured. Is this a known difference? I can find no online references to the part number on the auto part - 338857B.

Any further information on these queries or any other known differences between the manual and auto carbs gratefully received.

Yeah, the linkages are very different. If the weber was fitted correctly you should still have the kickdown spring and correct cable coming from the auto box.

Here is a picture of the linakge - https://www.clubgti.com/forums/proxy.ph ... 947f2d70e1

Thanks. That’s very helpful.

I had a little bit of trouble with the link and had to copy and paste it into my browser. This is a direct link to the same picture.

I also then found these pictures online showing the throttle linkage connected. I now know what to check is attached to the Weber.
