[VR6cramp 0]

I need some help from all you rado nuts out there with alot more knowledge than myself :)

 

Basically my VR6 has started to kick out some nice black smoke! Also when starting it leaves a nice black soot splatter on the ground blow the exhaust :shrug:

 

Also i am sure its using a lot more fuel than it used to but maybe that it just me.

 

Could it be overfueling? if so what could be the possible causes and solutions???

 

Thanks you your help will be much appreciated :)

I'd guess at a failed lambda probe, but you really need to get it scanned for fault codes to be sure. There's a sticky thread showing people with the gear to do this and their locations.

Lambda doesn't engage until 70 deg water temperature.

 

First thing to check / replace is the ECT (AKA "Blue coolant sensor"). The engine probably thinks the car is in Siberia and is fuelling it to suit.

Well i have just been round a mates house and he has hooked it up to the Vagcom the faults found were:

 

00537 - Lambda (Oxygen Sensor) Regulation

08-00 - Control Limit Surpassed

00533 - Idle Speed Regulation

10-00 - Adaptation Limit Not Reached

 

We are going to replace the Lambda sensor to hopefully sort that issue!

 

Has anyone ever had the other fault before or know of what it might be? :shrug:

 

Thank you in advance for any info
