Berlingo I 1,9D M WJY 2002 - electrical issue

Post by TessG »

Hello everybody,

I have Berlingo I 1,9D M WJY year 2002 and unfortunatelly I have a big issue with it.

SOMETIMES, when I want to start the engine, the warning lamp of engine heating does not light up, the clocks with temperature and tachometer do not work, the engine is cold and it is not possible to start the engine. This issue does occur also while having the engine warm - when I switch off the engine after a ride and switch on it again, the lamp of engine heating does not light up but the engine starts and the engine has hard sound all the drive. The car goes but without perfomance and there is a black smoke coming from the exhaust.

What I had changed - timing belt, candles, heater plug relay, battery.
What was checked - Fuel pump and valve clearances are OK.

Because the issue happens only sometimes, it seems to be more an electrical problem than mechanic.

Does someone have experience with this kind of issue? Does someone know what could the problem be? May someone help me with that?

Wish you a lot of kilometers (miles) with no problems.

Regards

Hi and welcome.

It sounds like the vehicle has gone into a backup mode (reduced performance) until the fault is fixed.

The best thing you can do is to find somebody with a Lexia to diagnose it and find out what the fault codes are, then post them up here. This may save some guessing as there could be several issues concerning the emissions, air & fuel etc.

Post up the VIN here so we can look at the exact engine and options.

They won't be - these are chargeable form Citroen - we don't supply those.

If you want a specific diagram, you will need to supply your VIN (as already asked for in your other post) and state for which part and we may be able to help you.

Your Berlingo is a BERLINGO VP ESTATE VAN 1.9 D 71 (DW8B) Manual gearbox 5, so has the DW8B engine with Lucas pump. This should have basic emissions fault code reading.

As this is a left hand drive model, do you have the following port located by the driver's left side?

I will check it. But what technicians told me, the diagnose of this model is stupid and does not remember the failures..

You should still get some codes if it is related to the emissions equipment.

After a discussion with my technician, in his opinion the black smoke coming from the exhaust is happening because there is some issue while starting the engine - even the engine is warm, the system does send more fuel with air into the engine because it thinks, the engine is cold. My car is without turbo.

The black smoke issues are related to over-fuelling, but the common causes of black smoke are faulty injectors, a faulty injector pump, a bad air filter or a blockage in the air pipes restricting the oxygen supply, a clogged EGR valve / Gas Recycling Circuit (depending on engine).

Is this the semi ECU controlled mechanical injection pump system?

If so, it sounds to me like the ECU is failing to turn on sometimes, so no control of the glow plugs or timing advance? (I'm not sure what the electronic solenoids) leading to poor running when it does finally start.
