Lovely E92 325i coupe we had in this week, absolutely mint car but the rear end was showing its age abit. A new car to the customer, he wanted to bring a new lease of life to the car, and future proof it for him self.
We agreed a new rear subframe and mounting bush’s were required, as well as the customer insisting we replaced every suspension arm, nut and bolts to really freshen the car up.
The car ended up needing all the brakes, flexi pipes and handbrake shoes replacing as well while we were doing the rest of the work.
A rare car given years of new life and one very happy owner…..

New customer visited us this week, with an on going issue with his M135i.
Been to 2 separate garages and had a lot of work done trying to rectify the fault, a very bad knocking from the drivers front wheel.
The last diagnosis was the the steering rack was at fault and that the repair was going to be over £3000 to fix.
The customer wanted a second opinion from us and after a quick test drive and on ramp inspection we found that the driver side engine mount had completely collapsed!!
We have seen a few of these now, but never seen one so bad, the entire engine was basically sat on the subframe, no wonder his vehicle was knocking.
New mount fitted and car drives like it should again.

435d convertible in this week for what was almost a complete car shut down electronically of most of the car.
The entire K-can2 line had been brought down from what we suspected to be water ingress, because the even the rear boot release had failed this caused some issue as to how we could get into the boot. We finally broke through into the boot, got the lid open and found the ASD module ( sound amplifier ) to be sat in over 2 inch’s of water.
New ASD fitted and programmed, boot dried out and car was fault free ready to be collected.
These cars suffer a horrendous design flaw in what is a rain drain system that blocks up the rear 1/4 panels and floods the rear end of the car.
I’ll let the video show you just how much water we remove from these cars!
