    Hi,
    I had a scan done today thanks to Dave from B8 forum.
    It shows 2 errors which I want to fix asap.

    FIRST ONE
    17664/P1256 - Engine Coolant Temperature Circuit (G62): Open / Short to B+

    Possible Symptoms
    Difficulties with starting a cold engine.
    Diesel: an indication is extreme long time burning time of the glow indication light.
    Starting the engine when engine is warmish or warm, idle rpm immediately is 1200 - 3000 rpm.
    RPM at idle is irregular.
    With all engine temperatures seldom idle rpm will vary between 900 - 1000 rpm.
    With engine warm (90 °C) the engine temperature suddenly drops (70 °C) and slowly comes back to 90 °C.
    Bad acceleration during warming up.
    Possible Causes
    Wiring and/or connections faulty
    Engine Coolant Temperature Sensor (G62) faulty

    Possible Solutions
    Check wiring and connections
    Check / Replace Engine Coolant Temperature Sensor (G62)
    Special Notes
    In MY 1995-2002 (?) in Europe at VW-cars the G2/G62 had the bad reputation of breaking down often. The default G2/G62 is black and all replacements are green.

    SECOND ONE
    17994/P1586/005510 - Engine Mount Solenoid Valves (N144/N145): Short to Plus

    Possible Causes
    Wiring/Connectors from/to Engine Mount Solenoid Valves (N144/N145) faulty
    Engine Mount Solenoid Valves (N144/N145) faulty
    Possible Solutions
    Check/Repair Wiring/Connectors from/to Engine Mount Solenoid Valves (N144/N145)
    Check/Repair Engine Mount Solenoid Valves (N144/N145)
    Category: Fault Codes

    Any idea if its easy to change coolant sensor? Would prefer to do it myself when I have a spare minute.
    Maybe price from stealers ?

    With the engine mount solenoid valve am I looking at new engine mount?

    hi mate the coolant sensor is not hard to do just fiddly as for the engine mount that if its the same as mine was just a broke wier again
    fiddly if the wier is broken to close to the mount.

    Thanks mate. I'm almost sure that my engine mount is screwed but not sure about this error. Is there a way to say which mount one to check?
    I've read about G62 being pretty common to die in B6's. Will have a look at it when have a bit of time. It's about 15 quid so not tragic.
