1.2 tsi - Fault code P0107
Posted: Fri Apr 25, 2025 10:52 am
Hi all,
I have a 2011 1.2 TSI Polo with the CBGA/B engine.
Just over a month ago, the timing chain guides snapped, so I had them replaced.
While the car was at the garage, they told me the catalytic converter had failed — but quoted £1.1k just for the part. I noticed GSF sell these for around £200, so I ended up replacing it myself.
However, I’m still getting two recurring fault codes:
P0107 – Manifold pressure sensor (MAP) low input
P0172 – System too rich (Bank 1)
To try and fix this, I’ve already replaced the MAF sensor and the pre-cat lambda sensor myself.
I’m kind of at my wits’ end now, and struggling to find anyone who can look at the car within the next few weeks. I really need it sorted by 14/05, as I’ve got a driving test that day — and I can’t take the test with engine lights on.
Does anyone have any advice or ideas?
Thanks in advance!
