Hi
My local garage has given me the following error code on my 56 plate Grande Punto 1.4 sporting active but says its OK to carry on driving. What does the error code refer to?
00321(141)

The code you've given means almost nothing really, unless someone else has the same code reader to translate it. EOBD error codes usually start with a letter, so possibly:

P0321- Crank/RPM sensor, or
P0141- Post-Cat lambda sensor.

A Crank sensor fault can cause non-start issues, so is fairly important to be investigated. A post-cat lambda sensor fault is less urgent (as it's use is to monitor the efficiency of the cat), but still needs investigation.
