Thread: Lupo 3l -need help

    Lupo 3l -need help

    Hi , i have a Lupo 3l and im having some annoying problems with this car since i bought it .
    1 when engine is cold at idle i have lots of vibrations and clattering noises like the engine mounts are broken, which are not ,so this possibility is excluded .I noticed that at idle rpms are fluctuating from 840 to 861 , torsion value is 0.0 to -0.5 from time to time .I noticed that if i press very gently the gas pedal the vibration and hard noises dissapear like magic , so i raised the rpms at 860 -880 .Best sound of the engine is with the rpms at 880-900 and at this rpms the car is very quite . I have to mention that the vibrations and clattering noises are significant low when the engine is hot , but i still have the clattering noise under torque and when downshifting gears also when gliding in neutral(eco).
    I want to fix the problem since raising the rpms is not a permanent fix .
    2 My dashboard is showing a very high consumptin then in real life , and i cant find if this is procent or a fixed value;for istance at consumption 4.4 l showed i have real consumption of 3.1 ,at 5.7 the real consump is 4.3 and i had even 6.9 and real was 4.5 .
    What i found with Vag that my dashboard is coded with the 1.9 diesel Pd , and the 1.2 pd is not shown in coding , only 1.4 pd and tdi and gas models ;i found this strange even if the coding cant be changed .the tires are new and respect the car dimensions .i also record 0.5-0.6 l/h at idle .
    Sorry for the long post

    Check the mounts fully. On the RHS (looking forward) there are long bolts going into the block. These should be changed every time the timing belt is renewed. Also check the compression on each cylinder.

    What is the part no. of the ECU?

    Part No is 6E0 920 800 J. Timing belt was changed 10k , 6months ago , and i think this is the mount that has to be removed for the belt to be changed and it was in good shape then .Motor feels very stiffed ,cant feel any play if i try to "shake " it .Is there other way to check it ?The bolts should be changed or the mounts ?Can u help me with the part no of the mount or the bolts that need to be changed ?
    Thank you

    6E0 920 800 J is the instrument part no., not the ECU (engine control unit). The bolts should be changed every time the belt is changed as they are otherwise considered likely to break. Mounting is here:

    http://www.parts-catalogs.info/volks...ent_id=1209604

    The two parts of the assembly 6E0199167F should not be separated as they are torqued to a specific value.

    Correct but not necessarily the mount, unless it has been tampered with.

    I dont seem to find those long bolts .what are they supose to do ?My steering wheel is on the left side so i should i see them on LHS in front of the passenger side ?A part no ? Sorry for so many questions but at this point the mechanics do whatever i told them to and charge apropriatly even if they think there nothing wrong with the parts since they all dont know what is the problem

    The bolts are in the link, 18 & 19. All 3L's are LHD! The bolts will only be the cause of the problem if they are broken, whereas the mount may be if it has been tampered with.

    Thank you for the link Rab i will check the bolts again today .ecu no is 045 906 019 AE

    Checked the car yesterday , the bolts are ok , the mounts are ok , the bone mount is brandnew , i will try to change the gearbox mount to see if something will change ,its cheaper ;also checked the "alternator flywheel" wich seems to be ok too.the consumption showed is 8.2 now on 60 km in town .i discovered that my tank shows 32 l wich is false , i always fill the tank until it overspills and im using the black knob for reserve too so i must have atleast 41 l in the tank .im starting to hate this car .
