Thank you for your time and effort Steve Q, most appreciated .
I have ordered suction cup clamps specific to this job and will give it a go.
My Audi is the 2003 A4 1.8T, which has had a ridicules amount of money poured into it by the previous owner, and the softop was replaced in 2017. So I was prity disappointed when the glue failed, in the heat last summer, 39 degree's in Jersey!!
Finding parts is problematic, as my Audi dealers don't stock anything for this age of car, obsolete apparently. I need a new rear light unit, found one on Ebay for £95.00, my local car parts company was charging me £157.00!!
I was advised by my Audi dealership to scrap the car as they can't get any parts or solution to the roof problem.
Audi's you just have to love them to own one!!!!
cheers Chris...
