MOT

Arrived at My Garage in Emersons Green to find that the MOT chap that I normally see was away on holiday but no problem as another technician was doing the MOT's that day.
As the car was driven into the workshop I hung around outside waiting and watching. After about 20 mins I couldn't resist going in to see how it going.

Not good as the car was failing on the emissions test, he tried a couple of times and called a colleague over for verification, "sorry but your cats knackered".
I found this very hard to believe because the cat was less than a year old and supplied by Brown and Gammons, who are a well respected MG specialist.

The MOT continued and the car passed on everything about from the emission test. Armed with this information I called B&G to ask for their advice. They were very helpful and asked when I could bring the car back to them for them to inspect for themselves, so I wanted to get it sorted ASAP, so agreed to drive the 2.5 hours on Saturday morning.

Got to B&G this morning before they opened, I was impressed to get there that early, and duly waited for them to open. They quickly diagnosed that the cat had failed and offered to replace then and there. Interestingly the sound from the exhaust on the drive home was one that I was familiar with but hadn't heard from my car for a little while now. So I'm confident that the retest of the MOT next Friday should be a formality but there still remains the issue of lost horsepower and why the cat had failed.

After a few searches on Internet, it seems that most cats fail because of either over fuelling and petrol contaminating the cat or compression loss, this comes back to the earlier problem experienced at the rolling road session.

So the next sprint at Curborough next weekend will still be with a car that I'm not sure exactly is going on with the engine but hopefully the following week when the compression tests are done, should be sorted and we can find those missing horses!!
