Hi all,

It would actually be really useful to have a summary of which parts are the solid version, for diesels (in my case!) and the part numbers. Can anyone help with this?

EDIT: I took the time to answer my own question and have come up with what I believe to be the ultimate cross-reference resource for A2 diesel solid TCA / wishbones! Here are all the part numbers from brands I’ve heard of:

EDIT: To be clear, the above referenced parts may be referred to as forged or cast; there is some debate as to how they are made - but in any case we are talking about the solid type of arms that are fitted to earlier A2s up until around 2002; later versions are the pressed steel plate type that rot unseen (and are hence the catalyst for this thread in the first place). On some sites these parts are referred to as being manufactured from steel, but I can assure you that to the best of my knowledge, if you order any of the above then they will be the correct (early) type.

EDIT 2: While updating the above to include MOOG and QH part numbers, I found this incredible resource which has even more manufacturers & part numbers listed: 8Z0407151L and 8Z0407152L

Note that as mentioned above, the petrol arms are different only in as far as the rubber bush that comes supplied with the arms is different (lighter duty), however the consensus is that all arms will physically fit all cars - and I have yet to see any reports that fitting diesel arms to a petrol car (or indeed, the other way around) makes any noticable difference in ride, noise, vibration or longevity! For completeness, the petrol Lemforder arm part numbers are 27034 and 27035.


Other necessary info needed for this job that I’ve mined from this thread for the benefit of myself and other members:

8Z0407183A - bonded rubber bush (The big one mounted on the console fixed to the subframe that the plain end of the control arm locates into)

Bush removal / installation tool: as per the above post by Mike
