Ok not so :D more :[

Guys, Have an issue....

Yesterday I drove to Cardiff from Bristol (this isnt the issue, but I can understand why some would thing it would be..) and all was fine.
I started leaving cardiff later in the day and all was fine.
A few miles into my return journey I decided to put £40 of diesel in (as I was heading up to north london).

After leaving cardiff and getting over the bridge, I started to notice a problem, the car felt lumpy. No loss of power at this point, happy to sit at 80 with the cruise on.
Now, I then hit a hill (anyone who does the M4 to bristol from Wales will know this hill). The car upped the revs to stay at 80 but not much happened.
So i planted my foot to see if i could get up the hill quicker, the car dropped to 4th and the revs hit 4000 then stopped, the power was just not there.
Its like it was being limited at 4000rpm for some reason.

Got to the top of the hill and onto a nice flat part and planted my foot again, same result, car would hit 4000rpm then feel like crap!

It had a new injector a couple of weeks ago and since has been running fine. Oil level is fine. Insp1 is about 8500 miles away (oil service done a few months ago).

Any suggestions as to what could be wrong?
Its odd that I only noticed the problem after putting some diesel in, could it be something as simple as crap diesel?

Any help would be appreciated as always :]

For info: the car made it to north london with no significant drop in economy, if that means anything!

Oh and yes, it was diesel, i've checked the receipt :D
 
could be a boost pipe problem, like a split or disconnected pipe. It could be possible that the pipe leading to the boost control valve has an issue, resulting in the ECU cutting the fuel at whatever PSI it's set to do that, a form of limp mode if you will, since there's no EBC limiting the boost
 
sounds like limp home mode if its limiting the revs at a certain point, dodgy sensor maybe? MAP, electrovalves etc.
 
Thanks.

Kul on e36coupe has recommended a gearbox reset, which I will try later (as have about 80miles to drive.

£50 for the part, 6 hours of labour at your dealer to fit it :p

The labour parts the problem really, if it would be something they would need the car for days rather than hours, then i would need to think about where I book the car into :/
 
Mass Air Flow sensor has gave in. Or a split Vaccume pipe. Had similiar to our car, turned out it was the Split Vaccume pipe, put the car in limp mode.

Car in question Merc CDI.
 
problem has evolved....

it now wont start. turns over fine but the car wont actually start :/
AA on their way :(
