Case Study

Jaguar XKR Front Subframe Replacement

Our customer booked their Jaguar XKR 4.2 Auto in for an MOT and service, but it failed the MOT because the front subframe was badly corroded and seriously weakened. This is classed as a major defect, meaning a front subframe replacement was needed before the car could pass. The MOT also highlighted a faulty offside front windscreen washer and a tear in the inner wall of the offside front tyre, both also classed as major defects.

Fault Codes

No fault codes – this was an MOT failure for the following major defects:
Front subframe – corroded and seriously weakened
Windscreen washer – offside front not working
Tyre – offside front inner wall torn due to structural separation

Common Symptoms
  • MOT failure for a corroded front subframe
  • Heavy rust and a large hole in the subframe
  • Offside front windscreen washer not working
  • Tear in the inner wall of a front tyre
Jaguar XKR Subframe Inspection

Following the MOT failure, we investigated the subframe further. Our MOT tester confirmed that a new subframe would be needed for the car to pass. There was a lot of rust present, along with a very large hole in the subframe. Although the hole could have been welded, replacing the whole subframe was going to be the more cost-effective and longer-lasting option for our customer.

Once the MOT was complete, we passed the Jaguar to one of our Jaguar specialist technicians. They replaced the front subframe along with the nearside front engine mount. Because the wheel alignment must be checked and adjusted after a subframe replacement, we also carried out full four-wheel geometry work. Our technician then traced the faulty windscreen washer to a broken pipe and repaired it.

With the new front subframe and engine mount fitted, the geometry set up correctly and the washer repaired, our customer's Jaguar XKR passed its MOT and was back on the road safely.
