loving my bravo, miss the coupe, but still have an eye out.

well today I drove to Eastbourne, filled up after 2 miles of leaving the house, then on the way there i get loss of power under 2k revs, bit like the handbrakes on, like it all day. drove home, seemed to sort its self out, now back to no power. not smoke so ruled out turbo, any suggestions?

Ive seen EGR threads, is it that? just to add, no engine warning lights are on.

thanks guys in advance

It could be EGR, but that throws an engine warning light. Does yours have a DPF?

Hi, i dont think it does?

Not that then; they were fitted from 2010 or thereabouts.

its wierd, no faults, could it just be dirty petrol maybe? happened after i filled up yest. may get some redex and see if that helps??

Petrol or diesel?

If it's the diesel then take it out for a run and thrash it (few miles on m-way or similar at 80 in 4th should do it), this often cleans up sooting in various places. You may see black smoke as whatnot are aiming to do is get the exhaust hot enough so the egr opens and deposits it's carbon contents to be burnt.

Petrol, errr...... Battery off and ecu reset??

It's mjet, I'm Actually thinking boost leak?

Check egr and for split hoses. Boost pressure sensor also a likely culprit which is easy to remove and clean. Further from there afm meter issue etc.

Had loads of these troubles with our mjet 140 147.


Do you have a code reader? Faults should be logged

I haven't got a code reader, but I'm going to have the under tray off in a while and check out all the hoses. Seems to be just long turbo lag.

My 120 is a mjet, but a 1.6 diesel.

I would.say boost peak but only if it's flat at the top end too. My coupe did have a low torque issue once, turned out the vac pipe to the dv was damaged.

sorry, its a 1.9 8v mjet. i think it may have been a bad tank of fuel because when i filled up again it seemed to be ok?!?!

Saying that. it may have happened again this morning, will kepep my eye on it today

I've had a couple of the 8v turbo diesels in Stilos and they suffer from intermittent boost sensor issues - mainly because the sensor is just in front of the left front wheel so it gets soaked if you go through a puddle which leaves the sensor a little, er, sensitive.
The loss of power usually only lasts a few seconds though.

thats good info tim, thanks. its been alright since i put a fresh tank in, and thats useful to know as a place to fault find if it happens again
