Why do all jobs on an E9 escalate? when I got the car it had brake servo's (cheap Chinese sh1t) that were slow to operate and worse slow to release plus fluid leaks from the top of the overhauled master cylinder, so I bought a pair (UK RHD car) of rebuilt units and thought it would be a quick job to refit them, the PO had relocated the PAS reservoir, altered the servo brackets, relocated the fuel vacuum unit and relays, , sorted through my parts and found correct brackets, longer hoses for the PAS, changed the imperial pipe ends back to metric, then found the calipers were sticking, removed them to reseal, then decided to fit the new sports Bilsteins and drilled discs that came with the car, then decided to blast the struts and backplates to repaint them with Kephos, so it goes on and on...... time to stop looking for jobs to do on it!
