Broken road spring

AdrianH · 10-07-23, 09:03 AM

Immediately I've got the Quattro running nicely again and a working radio/cassette player, and 'pa-clunk' –*the front O/S spring snaps. Great. First time I've ever had a spring break on any car actually.

What are the options here? I don't want to lower it, or uprate the springs or anything like that,*just original spec. Any pointers, or is it just a case of phoning around the usual suppliers and keeping an eye on eBay?

The same place that produced the uprated coils for the ur have the specs to be able to run off a set. Assuming that they’re still in business.
An original, but obviously used, set of coils was used to create the benchmark for the uprate.

The uprated versions made for a group buy came in two versions, iirc. 25%, or 30% uprate, but intending to retain standard ride height. A small oversight saw the free length of the springs not being set properly, resulting in loose springs on assembly until there was weight on wheels. That could easily have been corrected.

I do have a full set of original coils (1985 WR, non-a/c) sitting around from when I did my suspension rebuild. They’re surplus, but as I’m not in the country at present or for a while, they may be of little use to you. They’re also in need of properly cleaning up, and painting.

I'll PM you. Not getting any joy in the usual places and I need the car back on the road.

Be really careful, I sourced some from bilstein about three years ago to do my suspension and bush replacement. The ones supplied were the wrong height originally, and also wrong rate.

Problem here is the death of the quattroforum where all the information and discussion was for this, I tried to find it when I was looking

(Ignore this –*I missed Darren's earlier post)

Digging around on the internet, Bilstein claim their part number 36-227464 is a fit for the urQuattro – as well as the Typ 89 80/90 and Coupes. Specifically, a replacement for Audi part number 893 411 105 B which is obviously not the original spring p/n which I think is 853 511 115C.

Is anyone able to confirm this will work? Seems a bit iffy to me but if it gets the car mobile again without compromising the handling I guess it could be OK. At any rate they could do until something better comes along.

I must admit, not being able to obtain a spare part as simple as a road spring is starting to put me off these cars, much as I love them. Basically you need the car, and a shed full of replacement components.
