Hi not so long ago i had the PPP fitted to me WRX 2001 EU import and i have had the engine light come on twice since,
i have took it to Quembys in baldock to have it checked and they say the fault is the exhaust heat sensor

i was just wondering if this is the norm cos they say they will consider changing it but i never had the problem before they fitted the PPP

question is really should they replace this for free

Thanks
Geoff
