Hi, driving a T Reg EC11 and having a right problem. Can’t decide if it’s the Jake Brake or something else.
If loaded, after a couple of hours it starts to have problems pulling and sometimes I can only get about 50/60 kph out of it, it’s almost like the Jake Brake has partially asserted itself. It I stop for a ‘■■■’ break for 30-45 mins and then start up again it’s good to go for another couple of hours.
But typically everytime ive been near the company mechanic or the boss the ■■■■ thing wont do it!
It’s less of a problem when i’m not loaded but it’s still there hanging around.
Has anyone else ever come across this sort of a problem and if so, can you head me in the right direction of what ‘bit’ is playing up■■?

Driving me mad! Literally!
Thank you.
It sounds more like ‘the brain’ to me, You probably need to get it into a proper ■■■■■■■ workshop, so they can get it on the laptop, and check the faults out, as it sounds like it’s going on to ‘limp home’ mode
I’ve been on to the jakebrake site and have downloaded the installation manual and the troubleshooting document. Am out on the road at the moment in france on my way to Cherbourg for a pick up at the moment, truck will be parked up over the weekend so I will take the time to read the docs above and have a bit of a ‘thunk’ about it.
At the moment the boss suggests ‘just keep going’ as I do have this work around ( the stop and wait for a bit reset), until we can get it looked at properly.
Just want to be sure that it is the jakebrake and not something mind blowingly simple that is nothing to do with the jakebrake, and that i’m just not thinking of something that is staring me in the face! Ha ha.
Had a headlight go on me earlier this week, and after all the normal checks got the company mechanic out only to find I was looking at the wrong fuse and the correct fuse had gone. Did I feel a prat!!
Keep the info coming peeps. All suggestions gratefully received.
the maoster:
I’d be very doubtful that a “T” reg would have a brain sophisticated enough to go into any kind of safe mode.
I’d be more inclined to check that the motor is breathing properly and has no obstructions in the air inlet/filter.
You say it’s more noticeable when loaded, but that could be because you need more power to shift a heavy vehicle as opposed to a light one.
All the EC11s have ‘a brain’ as they are just the old L10s opened up a bit with Electronic fuel management, I’m fairly sure, and don’t forget T reg is 1999-2000 not as old as it sounds. It’s the time scale that makes me think it could be electrical, that and mates having similar problems.

oh please no, not electrical, not my favoured part of a truck ! (Chuckle), now if it was mechanical i’m your man, but electrics are a minefield to me!! I was so hoping this would be something simple and easily fixed…
The M11 did indeed have an ecu with it at the age stated,as I used to see them being built at Darlington,when I used to go in there on average 5 days a week with parts.
I would be very tempted to make that a starting point,to find the fault,but a visit to a ■■■■■■■ service centre will confirm or deny it.
The ■■■■■■■ M11 has got an ECU and also could be specced with a jake brake. I have come accross a similar problem to this that eventually lead to the engine not firing at all.
The stop solenoid can play up. It doesnt necessarily close completely but only partially causing a fuel starvation. I had to dismantle the stop solenoid which isn’t an easy job at the side of the road. It sits at the back of the pump/ecu etc and slightly below it. 4 allen bolts hold it together. If you do dismantle it, be careful, there’s washers, shims, o rings etc so just note the order in which they came out.
When i took it apart i noticed that a shim had become slightly concave which i assume was affecting how the solenoid was working. Flattened the shim out, re-assembled and the engine started, ran and pulled fine.
I could be completely wrong and i appoligise if i am but that’s all i’ve come across. Hope this helps somehow.
We had the same problem with our T Reg Alpha with an M11, it turned out to be a broken wire on a sensor which inturn put the engine into “safe” mode, £40.00 later on a new sensor and it was good as new!!!
So i would recomend going to an agent and let them plug the computer into it.
They sold quite well in France during the 90s, 11 litre, 14 litre and a fair number of EC127s with Detroits, there were also a few of those in Holland, a company which belonged to Penske I seem to recall.
Sounds electrical to me, as has already been said all M11 emgines had the ■■■■■■■ Celect brain on them, even some L10s had it, the EC10-350. If it is fitted with a Jake brake, and this problem has existed for a while, I think you would have had conclusive proof before now. The stress that the engine would be under with the Jake partially applied at the same time as its fuelling, would surely cause major failure bofore too long.
