    Hi i have these faults up on my 02 LCR, the symptoms are...on boost it is holding back and juddering big time, has no pull, as it were, in 1 -2nd gear it is not so bad, but once under full load it starts to happen. It then puts the car into Limp mode.
    Normal driving, idle etc are all fine, its just on boost the problem occurs.
    I tried a new MAF in it as i thought it may be that, but it has not cured it, so any help please as to what to try nest, i was thinking coilpack?

    The EML came on, flashed 5 or so times then went out, and has not been back on since, these are the fault codes i got from VAG COM, i have driven it today after clearing them and none have come back, but the problem pesists.

    16804 - Catalyst system bank 1, efficiency below threshold

    1. You cat is dying, needs replacing soon/ or now. Clear and if re-apears - replace cat - unless you have a decat ( speak to you tuner to get it mapped out).

    2. Coil pack for cylinder 4 need replacing. replace asap.
