Diesel cutting out and revs problem

23rd April 2016, 00:57

Hi guys, last few days my diesel started to act funny first i had a minor second radiator leak (eu spec with AC ) and fixed it with wurth leak stop solution , after that i noticed that while driving revs would start to drop faster than usual and eventualy at the stop the car would cutt out compleatly and chek engine would come up,or if it doesnt cutt out the revs would go between 650 and 900 ,oh yea and there would be some power loss during driving but that would clear by it self . I checked for the fuel line all good ,1 small air bubble at the top of the line that didn't move more than an inch by squeezing the pump thingy and drained the fuel filter . What do you think ,i narrowed it down to an ICV or thermo problem since the car doesn't really turn the fans on (coolant is new ).Please help those 43kw are stand alone problem but the power loss is killing me .

Probably an air leak in the fuel system, leakoff pipes are common, only use o.e replacement if required.

You think? Long time ago i had an air leak on the O Ring or fuel filter housing witch was caused by eaten fuel filter rubber seal ,but filter was replaced in less than 6 months ,and i don't remember filter causing a check engine light to come on ,also with false air in the system he has trouble starting witch i do not have now .Cheers for the reply

If the check engine light is showing then plug into a code reader mate.

A code reader won't work with this engine, only Peugeot specific software can rear the codes.

The diesel has no ICV. The fuel pump controls everything. There is only an anti-stall screw - and that certainly wouldn't lose you power

a 1.5d with a good coolant system will never need to use the fan unless sitting in traffic. The radiator core is huge.

Fuel pump failure is very rare.

These engines with ECU have a semi-electronic advance - which does go wrong on occasion and isn't worth repairing. The easiest way to check this is: on the side of the fuel pump where the 4 hard lines come out. There are 2 plugs, black and blue. Both plugs are 2 pin. disconnect both of them and drive the car. If the problem has gone then it's the electronic advance which has failed.

If you can live with the EML staying on, the electronic advance isn't needed so it can be left disconnected.

Wow guys i tought after few days that this thread is dead

Friend of mine did the diagnostisc there were some old errors stored since i had problems with the pump and alternator etc... Error codes were P1106, P1205, P1200,P 1300 ,P1516. Beside those there was error for coolant and real time data showed on idile temperatures from 26 degrees to 90 in matter of seconds ,than back to like 50, so thermo is definitly gone but since they don't have those old school thermos that get stuck in open or closed position this just went mad. For now we erased those errors and outside temperature droped from 27-28 degrees to like 5 so no problem with rev drop but i will definatly change thermo for now since is 5 euro fix and start from there.Thanx for the help !

So it's peugeot planet software that's needed then?

P1205 is the electronic advance in the pump!

Wipe the codes and see what comes back

Ideally. Some of the professional garace readers can see them though. like sealey etc.
