Twice in the last 2 weeks I've had the "drivetrain malfunction" error message. Both times it was while moving in slow town traffic, roughly 3 miles from a cold start. Both times the message has lied when it said "performance is reduced". Over roughly 400 miles in between the two instances, the car hasn't run any differently to how it normally does.

It's MOT day tomorrow, and I had already asked my man to change the brake fluid and the fuel filter while he's got the car. When I get there, I'll ask him to run a diagnostic as well.

I'll update tomorrow.

Mot passed, brake fluid & fuel filter changed. 2 stored codes, one;- EGR "mechanical failure near open position", the other;- EGR "mechanical failure near closed position".

I'm going to be doing an oil & filter change (and the air and pollen filters) in the next few days, so I'll whip the EGR off and give it a blast with some dedicated cleaner while I'm at it. Then if I get the error again, I'll have to bite-the-bullet and replace the EGR.

Good to hear it passed the MOT and an easy fix....
