Judder, lack of power or an overheated particulate filter due to the 2.0 CDTI software (Insignia A, 2009 and 2013 campaigns)

Engine / equipment

Opel Insignia A 2.0 CDTI

Period mentioned

2009–2012

Symptoms

Engine judder and noises in the exhaust, or loss of power with the engine warning light on.

Possible cause described

ADAC lists two Opel campaigns with new 2.0 CDTI engine-ECU software: in December 2009 (model years 2009 and 2010, 21,200 cars in Germany), for a fault that could cause judder, exhaust noises and, at worst, overheat the particulate filter; and in July 2013 (built 2009 to 2012, 61,000 in Germany), for a fault that could reduce power and, at worst, damage the engine, flagged by the engine warning light.

Check for the garage

Ask Opel by VIN whether the ECU has the software from both campaigns (each takes half an hour and is free). If the engine light comes on with loss of power, read the codes before replacing parts; if the exhaust smells burnt or smokes, stop and let it cool.
