8v 2.0 hdi running / starting issues

Post by basberlingo »

Hi

Does anyone know of a common fault with the 8v 2.0HDi which causes the following:

Very poor starting from cold, white smoke when eventually starts. Then once started very rough / lumpy, if you attempt to rev the engine it just cuts out when first started. Once stabilized very lumpy poor running then if you rev and take the foot of the accelerator it stalls. This happens also when approaching a round about when the clutch pedal is pressed. This continues to happen when the car is warmed up but not as persistent.

If this was just a starting issue I would lean toward glow plugs / relay. But as this is the running of the engine in general. A mechanic has apparently replaced the relay, but no pre ignition light is visible or ever has been since owning the car (5+ years).

I have no experience of this vehicle as it belongs to a family member, so before I start wanted to get some experienced opinions.

Having done some research my initial thoughts are leak off pipes drawing in air. How common are injector faults on these engines?

Do the injectors need coding to ecu?

Thanks in advance,

Welcome :-D

That's pretty unusual for a 2.0 HDi - normally they either run OK or they don't. It won't be glow plugs, as they will start anyway, nor leak off pipes, as these are common rail engines, and the injectors operate at very high pressures. It could be a problem with the HP pump, or possibly an air leak on the low pressure side if it's a Siemens injection system (but again this is unlikely as that would likely just cause a fail to start based on low fuel pressure on the rail). My best guess is that the head gasket is away - although that too is unusual on a 2.0 HDi.... Beyond basic cooling system checks (is it using water / is the system pressurised), then it would need to go on a Lexia to have a look at the live data to see if there are any anomalies. There might be a Lexia owner near you: http://www.frenchcarforum.co.uk/forum/v ... 19&t=29178" onclick="window.open(this.href);return false;

But the leak off pipes if fractured would introduce air into the fuel system.?

No oil or coolant are being consumed and cant see with the pressures involved the head gasket wouldn't have blown big time by now.....

Lumpy runing due to poor compression due to blown head gasket - white smoke dead giveaway.

Wouldn't the issues become worse when warmed up not subside......

Not necessarily.... what does the smoke smell of will be the first test. There's a possibility that it's broken a valve rocker - they do sometimes just let go - which would result in one cylinder not firing.

The smoke is when the car first starts.......It not constant.

I have the same problems.. worse when cold starting.. lumpy and I have to be careful at junctions..no oil use at all and pretty fair fuel consumpion.. pre heater has all but stopped the lumpyness when starting at home but if the car is away from home and engine is cold.. she's lumpy for a good few minutes.
I've changed a bad .004 injector but that seems to have made little difference.. they're all below.002 now.
I'm now leaning towards the MAF.. smoke can be a bit stingy on the eyes.. if that helps and she has a puff of smoke that you can see at night in the following cars headlights on hard acceleration.
Gow plugs hardly ever come on in the Hdi until you get down to freezing.. I replaced all mine last year trying to find the source of the lumpyness .. but even after 250K all the gow plugs were fine and getting red hot.. and it still didn't cure it. let me know if you find a solution.

My initial thoughts were maf....I posted on another forum and was recommended this one as this is a generic french engine....First thing to check was leak off connection ..... will be taking a look this weekend. Just wanted to get all the probable issues before I started....

Just hope to god it's not the head gasket......

Surely if it were the head gasket you'd have mayonaise in your oil filler?

This is a brilll forum the knowledge base here is unbelievable.

All depends where the failure is.....I've had the typical mayo and then the ridiculous pressure in the cooling system.....can fail in a variety of places......This vehicle doesn't exhibit any of the above symptoms though.

What vehicle are you running?.. mileage?
It sometimes makes a difference..It helps to put all that info in the signature.
