My Lexus IS250 currently in for its MOT, just had a quick check and it's failed on the following.

- Nearside Rear Subframe mounting prescribed area excessively corroded significantly reducing structural strength (5.3.6 (a) (i))

Not sure what this means but is doesn't sound good. 😰

Car has flown though it's MOT every year for the last 10 years with no advisories aside from tyre wear. Certainly no advisories for subframe or any other corrosion.

What work will need to be done and how much is this likely to cost?

Any advice about this would be much appreciated guys

You'll need to show us pictures of the area in question.

Ah, that's unfortunate...

I'm afraid from the sounds of it that the corrosion may have reached the lower ball flange. If it has then its likely affected the reticulating dingle arm and then significant work would be required to bring it up to spec.

The LUMA shafts and hygroscopic marsel vane will then need aligning along with the serving bearings and panometric fan.

Expect anywhere in the region of £2000 to £2500.

Can you say that in English please?

As above you need pictures, but it either has corrosion or a hole within 30cm of the mounting point, as prescribed in this manual I found in a Google search.

Appendix A appears to be the guidance and the rule is below, if that helps.

It’s one of those three bullets.

Nooo, not the dingle arm! Hopefully the turbo encabulator is still intact...

Looking at pictures of corrosion rarely shows the full extent, that only becomes apparent once you start prepping for repair.

Almost invariably bigger than you think.

You'd probably do better asking for decent welders in your area.

The rear subframe will obviously have to come off before the corrective work can start.

A proper job will be a three zeros rather than two undertaking.

Just got back from the MOT tester. Luckily it's not the subframe that's corroded but the 4 parts connected to it including the bolt in the middle that need to be replaced.

The area circled is the subframe.
