My wife has a Hyundai Getz diesel (1.5 CRTD GSI) which starts fine from completely cold. It also starts fine after it's warmed up completely. The problem is when you try to start the engine when it has not warmed up enough. Revs won't go higher than about 1500 and you press the accelarator thick black smoke comes out of the exhaust. If you try to drive off while the car is in this state it won't move much faster than about 5 mph while it's giving out black sooty smoke out of the exhaust

hi ninjabadger, it's me again...you have also posted a message about the same problem on the "honest John" forum and I replied by ending with something like "...watch this space.."
Well..car came back from the garage and so far so good.
The following was written on the invoice:

THROTTLE BODY JAMMED SHUT UPON STARTING (so there is your problem clearly stated)
THROTTLE BODY REMOVED AND CLEANED, INCLUDING ACTUATOR.
THROTTLE BODY REFITTED.
EGR VALVE CLEANED.

IT IS RECOMMENDED THAT THIS CLEANING PROCESS IS CARRIED OUT EVERY OTHER SERVICE.

Now they said that the cause of the gunging up of these components was a faulty Exhaust Gas Return (EGR) valve solenoid. So, they also replaced the solenoid ! Or so they said..Now it's a reputable garage and I hesitate starting to suspect that they are not telling the truth about replacing the solenoid. They said that that's what their diagnostic tests indicated...but why on earth did diagnostics not pick that up in the first place?...me thinks..

Anyway...they did not charge me for replacing the solenoid. They said that once I'm totally satisfied that the car continues to work well (as far as this problem is concerned) then I can go in and pay them for the solenoid. (Aren't they generous!!)

So I'll give it a couple of weeks and see how it goes.

What do you think ninjabadger?

I would be interested in finding out how the cleaning process mentioned above is carried out so that I can carry it out myself because it's not a cheap job !! Also because it's really a lovely car in every other respect !

THAT'S WHERE YOU CAN HELP NINJABADGER! CAN YOU FIND OUT HOW THIS CLEANING PROCESS IS CARRIED OUT? I WILL FIND OUT SOONER OR LATER, ONE WAY OR ANOTHER !

Thanks..Nick

PS I will post the same solution on the Honest John forum in case there are other poor sods who can benefit from it. hi ninjabadger, it's me again...you have also posted a message about the same problem on the "honest John" forum and I replied by ending with something like "...watch this space.."
