My guess is that the buzzing noise is either solenoids or the stepper motor on the throttle. When the ECU is unsure about throttle position, it attempts to close it. A problem with the battery voltage may trigger such a behaviour. Some electrical buzzing is usually heard under the bonnet just before...

The next time this happens check the voltage of the battery. It may be loosing charge overnight, but then quickly charges once the engine has started. Check, clean and protect with silicone or other grease the terminals and any associated contacts. I think the problem is somewhere around the battery.

The driver's door was clicking loudly. Upon some research I found that this is often caused by the retainer shifting up or down in its rollers. So, looked into mine - it was in the low position. Apart from this, everything looked good. I found a cheap solution not involving taking off the door panel...

The same job again - took just over an hour, and bruises were avoided by padding the door sill with sheet foam. It is still a pig of a job... The first step is to remove three pieces of plastic: pull the kick panel near the clutch pedal, pull the panel near the door with the airbag switch on it, the...

First post updated, enjoy!

With a fuelling problem there will be abnormal trim values on OBD... You may also look at the boost pressure live readings, also on OBD. One more option is the dephaser stuck in the retarded position. If the case, then it may rattle on startup or may be just stuck. Hi Bob there isn't no fault codes ...

It is safe to remove the battery from the card, no programming required after.

Yes, the wires are short - design fault. They break because of it. A good idea is to extend them a bit.

The oils are listed in the Parts section of the forum. They are thinner than for many other cars. The oil is added to the box though the filling hole until it starts flowing out from the same hole. I usually trace a pvc tube there from the space under the bonnet, choose the largest diameter to make ...

The motor was making a clicking noise because one of power pins in the connector to the regulator was corroded and burnt. As I understand, it attempts to operate, but then looses the contact as the pin overheats. It can be also the connector between the door and A-pillar. The clicking stopped probab...

The engine started itself?!! At least the car didn't steal itself while speeding through a dozen of cameras... These two incidents involve different computers, both connected to the same UPC and battery. If there are no warning lights on the dash, then you have found a dangerous design fault, yet an...

When was the oil changed and what oil/filter were used?
Any warning lights recently?
Is it on the original turbo?

If you can get it from the breakers cheap, then go for it. Otherwise, just change the pulley and see...
Change the oil/filter, BTW. If suspecting oil failure, then run on an ester-based oil for a season; it will make the internals of the engine shining clean.

I think, all versions must be compatible, some are just better designed internally than the others. There is also a dephaser control solenoid valve, which is essential for the dephaser operation. It makes sense to check/replace it as well.
