what are the diagnostic codes? if they are manufacturer codes they should be 5 digits, if they are generated using a non manufacturer scan tool they will be 5 digits beginning with a letter, in your case most likely P for powertrain then four numbers ex. p0121, you may also have U codes or B codes which are basically body and communication codes. Scan the codes, write em down, clear them again, and see which ones come back. The better scan tool the more info you can extract from the vehicle. Keep an eye on the check engine light, immobiliser/security lights etc. Could be a key/programming/relearn issue. Im here if you need me.

Need more details here like petrol engine or diesel ,but torque sequence is easy start in the middle and alternate from side to side ,as for the torque then a petrol engine alloy head then 65lbs will suffice ,yes i dare say some expert will come back and say it has a special tool and you torque to so many newtons then back off 90? and tighten so many degrees ,well this old fogey does the proper way as on the assembly they pull the head down all at once with one big machine ,so start in the middle and pull down with a rachet lightly going from left to right one bolt at a time,then pull down a bit harder for the second pass then the last pass with the torque wrench .then have a cuppa and a ciggy ,visit the boys room and read the paper then pull it down again ,job done ,do not rush anything your not on bonus or the assembly line .These fancy tools that measure degrees are not cheap for a one off use and your not trying to impress a client that walks into the workshop either so do it the old fashioned way and you will not be far wrong,right iam off out now more ITVs to do ,vehicle inspections at the goverment test centre ,easy money for a old person like me who speaks the spanish
Needs to be checked at the dipstick,
Under the bonnet on the engine!
The warning light, on most vehicles,
Only comes on when the oil is drastically low!!!!
You can go to any good auto parts store and ask to borrow their ECM analyzer. Find the connecting plug (usually by the drivers left knee), connect the analyzer and turn your key to the ON position (do not start the car though). The ECM analyzer will read the codes in your cars computer and tell you why the light is on. You will also have the option to RESET CODES so you can see if the light resets and stays out.
Common problems (usually identified by a display of "factory code XXX: on the ECM analyzer) are:
A bad "batch" of gas.
Loose fuel filler cap.
Misfire (usually caused by using other than premium gas in an engine such as yours).
If it is something wrong with your emission system, the ECM analyzer will point you in the right direction. Good luck!
petrol or diesel require different oils.and ambient temperatures come into play.for average temps of say minus 5C to plus 30C use 20/50 (the best you can afford)it dont matter if its synthetic or normal cos it should be changed every 3000 miles wih a new filter.this is from toyota WORLDWIDE.(NATO/WHO use them all over africa/middle/far east/Russia.who is going to argue....
All VW product have plasma coated bores and for this reason will "use"oil.the workshop manual says "1 litre every 350 km is ACCEPTABLE".I have NEVER had a car THAT BAD,unless worn out.
check your oil every 500 miles MAX.and use 10/40 semi synthetic.(as per VW Europe/middle/far east manual.)change every 10k inc filter.
