Hello
Ive had a couple of lights on the dash and had limp mode a couple of times, and getting the following codes, which I have cleared a couple of times, and keep coming back.
16804 -Catalyst System; Bank 1: Efficiency Below Threshold
17978 - Engine Start Blocked by Immobilizer (car always starts fine)
17705 -Pressure Drop between Turbo and Throttle Valve (check D.V.!)
17559 - Long Term Fuel Trim Additive Air; Bank 1; Range 1: System too Lean
16891 - Idle Control System RPM: Higher than Expected.
What do you reckon this all points to? Lambda sensor? New Cat?
I have cleaned out the throttle body, and car has just had a major service including plugs, cambelt change and fuel filter.
If it is the lambda sensor, which is more likely to fail, the front or rear one?
Many thanks in advance.
