Some of our customers find that there convertible roofs on BMW 3 series, 6 series, Z4, Audi A3, Audi A4, Audi A5, VW Golf stops working. This can often be due to wiring problems in the loom where 2 or more wires have shorted out. We can trace this break in the loom and fix it without the need of an expensive replacement loom. A main dealer might quote you up to two thousand pounds to replace the loom, if not more. Here at German Tech we can repair the wiring loom for a fraction of the price and have many happy customers who can testify to this.
