I had had an intermittent problem with the EPC light coming on in my 1.6 16v. It only seems to happen at around 75mph but even then it isn't consistent. As soon as I turn the engine off and back on the light is cleared. Finally got it scanned today by any indy near me and had 2 fault codes:
16804 - Catalyst System; Bank 1: Efficiency below threshold
P0420 - 35-10 - - - Intermittent
17961 - Barometric / Manifold Pressure Signals: Implausible Correlation
P1553 - 35-10 - - - Intermittent
I was told I would need a new cat, new manifold pressure sensor and throttle housing cleaned (maybe replaced). Grand total £500
I had new cat fitted in 2009 and this EPC light first came on in May 2011 (was a one off so didn't investigate further) so the cat would have been 2 years old! Even now I can't believe the new cat is knackered so was wondering what else it could be. I have done a few searches and seems that it could be the lambda(?) sensor that could be faulty? I had the cambelt done around May last year, also had a service shortly after which the aux belt tensioner snapped and was replaced. Is it possible one of these is linked to the problem (I also have a tapping noise from the engine bay, most noticable when cold).
Any thoughts would be much appreciated
